19 <sect>Installation (Original version by Iain Phillips, G0RDI)
24 This section describes the installation of DX Spider v1.35 on a
25 <htmlurl url="http://www.redhat.com" name="RedHat"> Linux Distribution.
26 I do not intend to try and cover the installation of Linux or the setup
27 of the AX25 utilities. If you need help on this then read Iains original
28 HOWTO on the <htmlurl url="http://www.dxcluster.org" name="DXSpider">
32 I am assuming a general knowledge of Linux and its commands. You should
33 know how to use <em>tar</em> and how to edit files using your favourite editor.
36 The crucial ingredient for all of this is
37 <htmlurl url="http://www.perl.org" name="Perl 5.004">. Now I know Perl 5.005
38 is out and this will almost certainly work with it, but
39 <htmlurl url="http://www.redhat.com" name="RedHat 5.1"> comes with 5.004.
40 <em>Be Warned</em>, earlier versions of
41 <htmlurl url="http://www.redhat.com" name="RedHat"> <bf>do not</bf> come
42 with 5.004 as standard, you need to
43 <htmlurl url="ftp://upgrade.redhat.com" name="upgrade">
45 <P>In addition to the standard Red Hat distribution you will require the
46 following <htmlurl url="http://www.cpan.org/CPAN.html" name="CPAN"> modules: -
52 <item> Data-Dumper-2.10.tar.gz
53 <item> FreezeThaw-0.3.tar.gz
54 <item> MLDBM-2.00.tar.gz
55 <item> TimeDate-1.08.tar.gz
57 <item> Net-Telnet-3.02.tar.gz
58 <item> Curses-1.05.tar.gz
59 <item> Time-HiRes-01.20.tar.gz
65 <em>Do</em> get the latest versions of these packages and install them
66 but use the above list as the earliest versions usable.
71 I will assume that you have already downloaded the latest tarball of
72 the DXSpider software and are ready to install it. I am assuming version
73 1.35 for this section but of course you would use the latest version.
76 Login as root and create a user to run the cluster under. <bf><it>UNDER
77 NO CIRCUMSTANCES USE ROOT AS THIS USER!</it></bf>. I am going to use
78 the name <em>sysop</em>. You can call it anything you wish. Depending
79 on your security requirements you may wish to use an existing user,
80 however this is your own choice.
88 Now set a password for the user ...
93 # Retype new UNIX password:
94 passwd: all authentication tokens updated successfully
97 <sect1>Installing the software
100 Now to unpack the DX Spider distribution, set symbolic links and group
101 permissions. Copy the tarball to /home/sysop and do the following.
105 # tar xvfz spider-1.35.tar.gz
106 # ln -s ~sysop/spider /spider
107 # groupadd -g 251 spider (or another number)
110 If you do not have the command <em>groupadd</em> available to you simply
111 add a line in /etc/group by hand.
114 # vi /etc/group (or your favorite editor)
117 You also need to add some others to the group, including your own callsign
118 (this will be used as an alias) and root. The finished line in /etc/group
119 should look something like this
122 spider:x:251:sysop,g0vgs,root
126 The next step is to set the permissions on the Spider directory tree and files ....
129 # chown -R sysop.spider spider
130 # find . -type d -exec chmod 2775 {} \;
131 # find . -type f -exec chmod 775 {} \;
135 This last step allows various users of the group <em>spider</em> to have
136 write access to all the directories. This is not really needed just yet
137 but will be useful when web interfaces start to appear.
140 Finally, you need to fix the permissions on the ax25_call and netrom_call
141 programs. Check where they are with the <em>locate</em> command and alter
142 the permissions with the <em>chmod</em> command like this ..
145 # chown root ax25_call netrom_call
146 # chmod 4775 ax25_call netrom_call
149 <sect1>Setting callsigns etc
152 Now login to your machine as the user you created earlier. In my case that
153 user is called <em>sysop</em>. Once logged in, issue the following commands ....
159 $ cp perl/DXVars.pm.issue local/DXVars.pm
161 $ vi DXVars.pm (or your favourite editor)
165 Using the distributed DXVars.pm as a a template, set your cluster callsign,
166 sysop callsign and other user info to suit your own environment. Note that
167 this a perl file which will be parsed and executed as part of the cluster. If
168 you get it wrong then perl will complain when you start the cluster process.
169 It is important only to alter the text of any section. Some of the lines look
170 a little odd. Take this line for example ....
173 $myemail = "ianmaude\@btinternet.com";
177 There appears to be an extra slash in there. However this has to be there
178 for the file to work so leave it in.
180 <P><bf>PLEASE USE CAPITAL LETTERS FOR CALLSIGNS</bf>
183 DON'T alter the DXVars.pm (or any other file) in /spider/perl, they are
184 overwritten with every release. Any files or commands you place in /spider/local
185 or /spider/local_cmd will automagically be used in preference to the ones in
186 /spider/perl EVEN while the cluster is running!
189 Save the new file and change directory to ../perl ....
196 Now type the following command which creates the basic user file with you as
203 <sect1>Starting up for the first time
206 We can now bring spider up for the first time and see if all is well or not!
207 It should look something like this ...

223 If all is well then login on another term or console as <em>sysop</em> and
224 cd to /spider/perl. Now issue the following command ...
231 This should log you into the cluster as the sysop under the alias callsign we
232 set earlier. In this case the callsign is G0VGS. The cluster callsign is set
233 in the DXVars.pm file in /spider/local. In this case we will assume that this
234 was set as GB7MBC. You should therefore see this when you login ....
237 G0VGS de GB7MBC 19-Nov-1999 2150Z >
240 If you do, congratulations! If not, look over the instructions again, you
241 have probably missed something out. You can shut spider down again with the
249 and both the cluster and the client should return to Linux prompts.
251 <sect>The Client program
254 In earlier versions of Spider, all the processes were Perl scripts. This
255 was fine but with a lot of users your computer memory would soon be used up.
256 To combat this a new client was written in "C". This client only works for
257 <em>incoming</em> connects at the moment. Before you can use it though it
258 has to be "made". CD to /spider/src and type <em>make</em>. You
259 should see the output on your screen and hopefully now have a small C program
260 called <em>client</em>. Leave it in this directory.
264 <sect1>Allowing ax25 connects from users
267 As stated previously, the aim of this document is not to tell you how to
268 configure Linux or the ax25 utilities. However, you do need to add a line
269 in your ax25d.conf to allow connections to DXSpider for your users. For
270 each interface that you wish to allow connections on, use the following format ...
273 default * * * * * * - sysop /spider/src/client client %u ax25
276 <sect1>Allowing telnet connects from users
279 Allowing telnet connections is quite simple. Firstly you need to add a line
280 in /etc/services to allow connections to a port number, like this ....
283 spdlogin 8000/tcp # spider anonymous login port
286 Then add a line in /etc/inetd.conf like this ....
289 spdlogin stream tcp nowait root /usr/sbin/tcpd /spider/src/client login telnet
293 This needs to be added above the standard services such as ftp, telnet etc.
294 Once this is done, you need to restart inetd like this ....
301 <P>Now login as <em>sysop</em> and cd spider/perl. You can test that spider
302 is accepting telnet logins by issuing the following command ....
305 client.pl login telnet
308 You should get a login prompt and on issuing a callsign, you will be given
309 access to the cluster. Note, you will not get a password login. There seems
310 no good reason for a password prompt to be given so it is not asked for.
313 Assuming all is well, then try a telnet from your linux console ....
316 telnet localhost 8000
320 You should now get the login prompt and be able to login as before.
322 <sect1>Setting up node connects
325 In order to allow cluster node connections, spider needs to know that the
326 connecting callsign is a cluster node. This is the case whether the connect
327 is incoming or outgoing. In spider this is a simple task and can be done in
331 Later versions of Spider can distinguish different software and treat them
332 differently. For example, the WCY beacon cannot be handles by AK1A type
333 nodes as AK1A does not know what to do with PC73. There are 4 different
334 types of node at present and although they may not have any major
335 differences at the moment, it allows for compatibility. The 4 types are ...
345 For now, we will assume that the cluster we are going to connect to is an
349 Start up the cluster as you did before and login as the sysop with client.pl.
350 The cluster node I am wanting to make a connection to is GB7BAA but you would
351 obviously use whatever callsign you required. At the prompt type ...
358 The case does not matter as long as you have a version of DXSpider later than
359 1.33. Earlier versions required the callsign to be in upper case.
362 That is now set, it is as simple as that. To prove it, login on yet another
363 console as sysop and issue the command ...
366 client.pl gb7baa (using the callsign you set as a node)
370 You should get an initialisation string from DXSpider like this ...
377 If the callsign you just set up as a cluster node is for an incoming connect,
378 this is all that needs to be done. If the connection is to be outgoing then
379 a connection script needs to be written.
381 <sect1>Connection scripts
384 Because DXSpider operates under Linux, connections can be made using just about
385 any protocol; AX25, NETRom, tcp/ip, ROSE etc are all possible examples.
386 Connect scripts live in the /spider/connect directory and are simple ascii files.
387 Writing a script for connections is therefore relatively simple.
390 The connect scripts consist of lines which start with the following keywords
395 # All lines starting with a # are ignored, as are completely
398 timeout timeout followed by a number is the number of seconds to wait for a
399 command to complete. If there is no timeout specified in the script
400 then the default is 60 seconds.
402 abort abort is a regular expression containing one or more strings to look
403 for to abort a connection. This is a perl regular expression and is
404 executed ignoring case.
406 connect connect followed by ax25 or telnet and some type dependent
407 information. In the case of a telnet connection, there can be up to
409 The first is the ip address or hostname of the computer you wish to
410 connect to and the second is the port number you want to use (this
411 can be left out if it is a normal telnet session).
412 In the case of an ax25 session then this would normally be a call to
413 ax25_call or netrom_call as in the example above. It is your
414 responsibility to get your node and other ax25 parameters to work
415 before going down this route!
417 ' ' is the delimiting character for a word or phrase of an expect/send
418 line in a chat type script. The words/phrases normally come in pairs,
419 either can be empty. Each line reads input from the connection until
420 it sees the string (or perl regular expression) contained in the
421 left hand string. If the left hand string is empty then it doesn't
422 read or wait for anything. The comparison is done ignoring case.
423 When the left hand string has found what it is looking for (if it is)
424 then the right hand string is sent to the connection.
425 This process is repeated for every line of chat script.
427 client client starts the connection, put the arguments you would want here
428 if you were starting the client program manually. You only need this
429 if the script has a different name to the callsign you are trying to
430 connect to (i.e. you have a script called other which actually
431 connects to GB7DJK-1 [instead of a script called gb7djk-1]).
435 There are many possible ways to configure the script but here are two examples,
436 one for a NETRom/AX25 connect and one for tcp/ip.
440 abort (Busy|Sorry|Fail)
441 # don't forget to chmod 4775 netrom_call!
442 connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh
446 # you can leave this out if you call the script 'gb7dxm'
454 connect telnet dirkl.tobit.co.uk
457 # tell GB7DJK-1 that it is connected to GB7DJK
458 # you can leave this out if you call this script 'gb7djk'
463 Both these examples assume that everything is set up properly at the other end.
464 You will find other examples in the /spider/examples directory.
466 <sect1>Starting the connection
469 You start the connection, from within a sysop enabled cluster login, by typing
470 in the word <em>connect</em> followed by a script name like this ....
473 G0VGS de GB7MBC 13-Dec-1998 2041Z >connect gb7djk-1
474 connection to GB7DJK-1 started
475 G0VGS de GB7MBC 13-Dec-1998 2043Z >
478 This will start a connection using the script called <em>gb7djk-1</em>. You can
479 follow the connection by watching the term or console from where you started
480 <em>cluster.pl</em>. You should see something like this ...
483 <- D G1TLH connect gb7djk-1
484 -> D G1TLH connection to GB7DJK-1 started
485 -> D G1TLH G1TLH de GB7DJK 13-Dec-1998 2046Z >
487 CONNECT sort: telnet command: dirkl.tobit.co.uk
488 CHAT "login" -> "gb7djk"
490 Red Hat Linux release 5.1 (Manhattan)
491 Kernel 2.0.35 on an i586
495 CHAT "word" -> "gb7djk"
497 received "Password: "
499 Connected to GB7DJK-1, starting normal protocol
502 GB7DJK-1 channel func state 0 -> init
504 <- D GB7DJK-1 Last login: Sun Dec 13 17:59:56 from dirk1
505 <- D GB7DJK-1 PC38^GB7DJK-1^~
506 <- D GB7DJK-1 PC18^ 1 nodes, 0 local / 1 total users Max users 0 Uptime
513 With later versions of Spider there is a set/login command for users. This
514 tells them when a user or node logs in or out. If you do not add a line to
515 your scripts after the final line (or before the client line which should always
516 be last if needed) then the login/logout information will be sent to users
517 <it>before</it> the login actually completes. This means if a node is
518 unreachable, it will continue sending logins and logouts to users even though it
519 is not actually connecting. To avoid this use the following line ...
526 In a script, this might look like ...
530 abort (Busy|Sorry|Fail)
531 connect telnet mary 3000
533 '>' 'telnet 44.131.93.96 7305'
540 Cluster links in particular suffer greatly from the presence of telnet echo.
541 This is caused by the telnet negotiation itself and can create at worst severe
542 loops. At best it creates unnecessary bandwidth and large logfiles! There are
543 things that can be done to limit this problem but will not always work dependent
544 on the route taken to connect.
547 Telnet echo itself should only be a problem if the connection is being made to
548 the telnet port (23). This port uses special rules that include echo negotiation.
549 If the connection is to a different port, such as 8000, this negotiation does
550 not happen and therefore no echo should be present.
553 Sometimes it is not possible to make a direct connection to another node and this
554 can cause problems. There is a way of trying to suppress the telnet echo but
555 this will not always work, unfortunately it is difficult to be more specific.
556 Here is an example of what I mean ...
560 abort (Busy|Sorry|Fail)
561 connect telnet mary.lancs.ac.uk
564 '\$' 'stty -echo raw'
565 '\$' 'telnet 44.131.93.96'
569 So, the first connection is made by Spider. This is fine as Spider uses the
570 Net_Telnet script from within perl. This actually uses TCP rather than TELNET
571 so no negotiation will be done on the first connection. Once connected to
572 mary.lancs.ac.uk, the command is sent to suppress echo. Now a telnet is made
573 to a cluster node that is accepting connections on port 23. The problem with
574 this link is that the negotiation is made by the remote machine, therefore you
575 have no control over it. The chances are that this link will create echo and
576 there will be no way you can stop it.
579 <sect>Automating things
582 Ok, you should now have DXSpider running nicely and allowing connects by cluster
583 nodes or users. However, it has to be shutdown and restarted manually and if
584 connection scripts fail they have to be started again manually too, not much use
585 if you are not at the console! So, in this section we will automate both.
586 Firstly starting the cluster.
588 <sect1>Autostarting the cluster
591 This is not only a way to start the cluster automatically, it also works as a
592 watchdog, checking the sanity of DXSpider and respawning it should it crash for
593 any reason. Before doing the following, shutdown the cluster as you did earlier.
596 Login as root and bring up the /etc/inittab file in your favourite editor. Add
597 the following lines to the file near the end ...
600 ##Start DXSpider on bootup and respawn it should it crash
601 DX:3:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
605 This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart
606 it should it crash for any reason.
609 As root type the command <em>telinit q</em>. DXSpider should start up
610 immediately. You will see the output on tty7 and if you login as <em>sysop</em>
611 you should find everything running nicely.
614 So far so good, now to automate script connections...
616 <sect1>The crontab file
619 Login as <em>sysop</em> and create a file in /spider/local_cmd called crontab.
620 Edit it with your favourite editor and add a line like this (I have included
624 # check every 10 minutes to see if gb7xxx is connected and if not
625 # start a connect job going
627 0,10,20,30,40,50 * * * * start_connect('gb7xxx') if !connected('gb7xxx')
631 The callsign involved will be the callsign of the cluster node you are
632 going to connect to. This will now check every 10 minutes to see if
633 gb7xxx is connected, if it is then nothing will be done. If it is not,
634 then a connect attempt will be started.
637 There are probably lots of other things you could use this crontab file for.
638 If you want to know more about it, look at the
639 <htmlurl url="http://www.dxcluster.org/cron.html" name="DXSpider"> website
640 at the cron page where it is explained more fully.
645 Starting with version 1.13 there is simple hop control available on a per
646 node basis. Also it is possible to isolate a network completely so that you
647 get all the benefits of being on that network, but can't pass on information
648 from it to any other networks you may be connected to (or vice versa).
650 <sect1>Basic hop control
653 In /spider/data you will find a file called hop_table.pl. This is the file
654 that controls your hop count settings. It has a set of default hops on the
655 various PC frames and also a set for each node you want to alter the hops for.
656 You may be happy with the default settings of course, but this powerful tool
657 can help to protect and improve the network. The file will look something
662 # hop table construction
667 # default hopcount to use
670 # some variable hop counts based on message type
681 # the per node hop control thingy
713 Each set of hops is contained within a pair of curly braces and contains a
714 series of PC frame types. PC11 for example is a DX spot. The figures here
715 are not exhaustive but should give you a good idea of how the file works.
718 You can alter this file at any time, including whilst the cluster is running.
719 If you alter the file during runtime, the command <em>load/hops</em> will
720 bring your changes into effect.
722 <sect1>Isolating networks
725 It is possible to isolate networks from each other on a "gateway" node using the
726 <em>set/isolate <node_call></em> command.
729 The effect of this is to partition an isolated network completely from another
730 nodes connected to your node. Your node will appear on and otherwise behave
731 normally on every network to which you are connected, but data from an isolated
732 network will not cross onto any other network or vice versa. However all the
733 spot, announce and WWV traffic and personal messages will still be handled
734 locally (because you are a real node on all connected networks), that is locally
735 connected users will appear on all networks and will be able to access and
736 receive information from all networks transparently. All routed messages will
737 be sent as normal, so if a user on one network knows that you are a gateway for
738 another network, he can still still send a talk/announce etc message via your
739 node and it will be routed across.
742 The only limitation currently is that non-private messages cannot be passed down
743 isolated links regardless of whether they are generated locally. This will change
744 when the bulletin routing facility is added.
747 If you use isolate on a node connection you will continue to receive all
748 information from the isolated partner, however you will not pass any information
749 back to the isolated node. There are times when you would like to forward only
750 spots across a link (maybe during a contest for example). To do this, isolate
751 the node in the normal way and put in a filter in the /spider/filter/spots
752 directory to override the isolate. This filter can be very simple and consists
753 of just one line ....
757 [ 1, 0, 'd', 0, 3] # The last figure (3) is the hop count
762 There is a lot more on filtering in the next section.
764 <sect>Filtering (Old Style upto v1.44)
767 Filters can be set for spots, announcements and WWV. You will find the
768 directories for these under /spider/filter. You will find some examples in
769 the directories with the suffix <em>.issue</em>. There are two types of
770 filter, one for incoming information and one for outgoing information.
771 Outgoing filters are in the form <em>CALLSIGN.pl</em> and incoming filters
772 are in the form <em>in_CALLSIGN.pl</em>. Filters can be set for both nodes
776 All filters work in basically the same way. There are several elements
777 delimited by commas. There can be many lines in the filter and they are
778 read from the top by the program. When writing a filter you need to think
779 carefully about just what you want to achieve. You are either going to write
780 a filter to <em>accept</em> or to <em>reject</em>. Think of a filter as
781 having 2 main elements. For a reject filter, you would have a line or multiple
782 lines rejecting the things you do not wish to receive and then a default line
783 accepting everything else that is not included in the filter. Likewise, for an
784 accept filter, you would have a line or multiple lines accepting the things you
785 wish to receive and a default line rejecting everthing else.
788 In the example below, a user requires a filter that would only return SSB spots
789 posted in Europe on the HF bands. This is achieved by first rejecting the CW
790 section of each HF band and rejecting all of VHF, UHF etc based on frequency.
791 Secondly, a filter rule is set based on CQ zones to only accept spots posted in
792 Europe. Lastly, a default filter rule is set to reject anything outside the filter.
796 [ 0, 0, 'r', # reject all CW spots
806 30000.0, 49000000000.0,
808 [ 1, 11, 'n', [ 14, 15, 16, 20, 33, ], 15 ], #accept EU
809 [ 0, 0, 'd', 0, 1 ], # 1 = want, 'd' = everything else
814 The actual elements of each filter are described more fully in the following
820 The elements of the Spot filter are ....
823 [action, field_no, sort, possible_values, hops]
827 There are 3 elements here to look at. Firstly, the action element. This is
828 very simple and only 2 possible states exist, accept (1) or drop (0).
831 The second element is the field_no. There are 13 possiblities to choose from
837 2 = date in unix format
840 5 = spotted dxcc country
841 6 = spotter's dxcc country
847 12 = callsign of the channel on which the spot has appeared
851 The third element tells us what to expect in the fourth element. There are
855 n - numeric list of numbers e.g. [ 1,2,3 ]
856 r - ranges of pairs of numbers e.g. between 2 and 4 or 10 to 17 - [ 2,4, 10,17 ]
857 a - an alphanumeric regex
862 The fifth element is simply the hops to set in this filter. This would only
863 be used if the filter was for a node of course and overrides the hop count in
867 So, let's look at an example spot filter. It does not matter in the example
868 who the filter is to be used for. So, what do we need in the filter? We need
869 to filter the spots the user/node requires and also set a default rule for
870 anything else outside the filter. Below is a simple filter that stops spots
871 arriving from outside Europe.
873 <tscreen><verb>$in = [
874 [ 0, 4, 'a', '^(K|N|A|W|VE|VA|J)'], # 0 = drop, 'a' = alphanumeric
875 [ 1, 0, 'd', 0, 1 ], # 1 = want, 'd' = everything else
880 So the filter is wrapped in between a pair of square brackets. This tells
881 Spider to look in between these limits. Then each line is contained within
882 its own square brackets and ends with a comma. Lets look carefully at the first
883 line. The first element is 0 (drop). Therefore anything we put on this line
884 will not be accepted. The next element is 4. This means we are filtering by
885 the spotter. The third element is the letter "a" which tells the program to
886 expect an alphanumeric expression in the fourth element. The fourth element
887 is a list of letters separated by the pipe symbol.
890 What this line does is tell the program to drop any spots posted by anyone in
891 the USA, Canada or Japan.
894 The second line is the default rule for anything else. The "d" tells us this
895 and the line simply reads... accept anything else.
898 You can add as many lines as you need to complete the filter but if there are
899 several lines of the same type it is neater to enclose them all as one line.
900 An example of this is where specific bands are set. We could write this like
904 [ 0,0,'r',[1800.0, 2000.0], 1],
905 [ 0,0,'r',[10100.0, 10150.0], 1],
906 [ 0,0,'r',[14000.0, 14350.0], 1],
907 [ 0,0,'r',[18000.0, 18200.0], 1],
911 But the line below achieves the same thing and is more efficient ....
916 1800.0, 2000.0, # top band
917 10100.0, 10150.0, # WARC
918 14000.0, 14350.0, # 20m
919 18000.0, 18200.0, # WARC
929 # This is an example announce or filter allowing only West EU announces
931 # The element list is:-
932 # 0 - callsign of announcer
933 # 1 - destination * = all, <callsign> = routed to the node
935 # 3 - * - sysop, <some text> - special list eg 6MUK, ' ', normal announce
937 # 5 - 0 - announce, 1 - wx
938 # 6 - channel callsign (the interface from which this spot came)
941 [ 1, 0, 'a', '^(P[ABCDE]|DK0WCY|G|M|2|EI|F|ON)' ],
946 In this example, only the prefixes listed will be allowed. It is possible to
947 be quite specific. The Dutch prefix "P" is followed by several secondary
948 identifiers which are allowed. So, in the example, "PA" or "PE" would be ok
949 but not "PG". It is even possible to allow information from a single callsign.
950 In the example this is DK0WCY, to allow the posting of his Aurora Beacon.
957 # This is an example WWV filter
959 # The element list is:-
960 # 0 - nominal unix date of spot (ie the day + hour:13)
968 # 8 - incoming interface callsign
970 # this one doesn't filter, it just sets the hop count to 6 and is
971 # used mainly just to override any isolation from WWV coming from
981 It should be noted that the filter will start to be used only once a user/node
982 has logged out and back in again.
984 I am not going to spend any more time on these filters now as they will become
985 more "comprehensive" in the near future.
987 <sect>Filtering (New Style v1.45 and later)
989 <sect1>General filter rules
992 Upto v1.44 it was not possible for the user to set their own filters. From
993 v1.45 though that has all changed. It is now possible to set filters for just
994 about anything you wish. If you have just updated from an older version of
995 DXSpider you will need to update your new filters. You do not need to do
996 anything with your old filters, they will be renamed as you update.
999 There are 3 basic commands involved in setting and manipulating filters. These
1000 are <em>accept</em>, <em>reject</em> and <em>clear</em>. First we will look
1001 generally at filtering. There are a number of things you can filter in the
1002 DXSpider system. They all use the same general mechanism.
1005 In general terms you can create a 'reject' or an 'accept' filter which can have
1006 up to 10 lines in it. You do this using, for example ...
1013 where ..... are the specific commands for that type of filter. There are filters
1014 for spots, wwv, announce, wcy and (for sysops) connects. See each different
1015 accept or reject command reference for more details.
1017 There is also a command to clear out one or more lines in a filter. They are ...
1024 There is clear/xxxx command for each type of filter.
1027 and you can check that your filters have worked by the command ...
1034 For now we are going to use spots for the examples, but you can apply the same
1035 principles to all types of filter.
1037 <sect1>Types of filter
1040 There are two main types of filter, <em>accept</em> or <em>reject</em>. You
1041 can use either to achieve the result you want dependent on your own preference
1042 and which is more simple to do. It is pointless writing 8 lines of reject
1043 filters when 1 accept filter would do the same thing! Each filter has 10
1044 lines (of any length) which are tried in order. If a line matches then the
1045 action you have specified is taken (ie reject means ignore it and accept
1049 If you specify reject filters, then any lines that arrive that match the filter
1050 will be dumped but all else will be accepted. If you use an accept filter,
1051 then ONLY the lines in the filter will be accepted and all else will be dumped.
1052 For example if you have a single line <em>accept</em> filter ...
1055 accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
1058 then you will <em>ONLY</em> get VHF spots <em>from</em> or <em>to</em> CQ zones
1062 If you set a reject filter like this ...
1065 reject/spots on hf/cw
1068 Then you will get everything <em>EXCEPT</em> HF CW spots. You could make this
1069 single filter even more flexible. For example, if you are interested in IOTA
1070 and will work it even on CW even though normally you are not interested in
1071 CW, then you could say ...
1074 reject/spots on hf/cw and not info iota
1077 But in that case you might only be interested in iota and say:-
1080 accept/spots not on hf/cw or info iota
1083 which achieves exactly the same thing. You should choose one or the other
1084 until you are comfortable with the way it works. You can mix them if you
1085 wish (actually you can have an accept AND a reject on the same line) but
1086 don't attempt this until you are sure you know what you are doing!
1089 You can arrange your filter lines into logical units, either for your own
1090 understanding or simply convenience. Here is an example ...
1093 reject/spots 1 on hf/cw
1094 reject/spots 2 on 50000/1400000 not (by_zone 14,15,16 or call_zone 14,15,16)
1097 What this does is to ignore all HF CW spots and also rejects any spots on VHF
1098 which don't either originate or spot someone in Europe.
1101 This is an example where you would use a line number (1 and 2 in this case), if
1102 you leave the digit out, the system assumes '1'. Digits '0'-'9' are available.
1103 This make it easier to see just what filters you have set. It also makes it
1104 more simple to remove individual filters, during a contest for example.
1107 You will notice in the above example that the second line has brackets. Look
1108 at the line logically. You can see there are 2 separate sections to it. We
1109 are saying reject spots that are VHF or above <em>APART</em> from those in
1110 zones 14, 15 and 16 (either spotted there or originated there). If you did
1111 not have the brackets to separate the 2 sections, then Spider would read it
1112 logically from the front and see a different expression entirely ...
1115 (on 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
1118 The simple way to remember this is, if you use OR - use brackets. Whilst we are
1119 here CASE is not important. 'And BY_Zone' is just the same as 'and by_zone'.
1121 As mentioned earlier, setting several filters can be more flexible than
1122 simply setting one complex one. Doing it in this way means that if you want
1123 to alter your filter you can just redefine or remove one or more lines of it or
1124 one line. For example ...
1127 reject/spots 1 on hf/ssb
1130 would redefine our earlier example, or
1136 To remove all the filter lines in the spot filter ...
1142 <sect1>Filter options
1145 You can filter in several different ways. The options are listed in the
1146 various helpfiles for accept, reject and filter.
1148 <sect1>Default filters
1151 Sometimes all that is needed is a general rule for node connects. This can
1152 be done with a node_default filter. This rule will always be followed, even
1153 if the link is isolated, unless another filter is set specifically. Default
1154 rules can be set for nodes and users. They can be set for spots, announces,
1155 WWV and WCY. They can also be used for hops. An example might look like
1159 accept/spot node_default by_zone 14,15,16,20,33
1160 set/hops node_default spot 50
1163 This filter is for spots only, you could set others for announce, WWV and WCY.
1164 This filter would work for ALL nodes unless a specific filter is written to
1165 override it for a particular node. You can also set a user_default should
1166 you require. It is important to note that default filters should be
1167 considered to be "connected". By this I mean that should you override the
1168 default filter for spots, you need to add a rule for the hops for spots also.
1170 <sect1>Advanced filtering
1173 Once you are happy with the results you get, you may like to experiment.
1176 The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU
1177 can be written with a mixed filter, for example ...
1182 acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
1185 Note that the first filter has not been specified with a number. This will
1186 automatically be assumed to be number 1. In this case, we have said <em>reject all
1187 HF spots in the CW section of the bands but accept all others at HF. Also
1188 accept anything in VHF and above spotted in or by operators in the zones
1189 14, 15 and 16</em>. Each filter slot actually has a 'reject' slot and
1190 an 'accept' slot. The reject slot is executed BEFORE the accept slot.
1193 It was mentioned earlier that after a reject test that doesn't match, the default
1194 for following tests is 'accept', the reverse is true for 'accept'. In the example
1195 what happens is that the reject is executed first, any non hf/cw spot is passed
1196 to the accept line, which lets through everything else on HF. The next filter line
1197 lets through just VHF/UHF spots from EU.
1202 <sect1>Filtering Mail
1205 In the /spider/msg directory you will find a file called badmsg.pl.issue. Rename
1206 this to badmsg.pl and edit the file. The original looks something like this ....
1210 # the list of regexes for messages that we won't store having
1211 # received them (bear in mind that we must receive them fully before
1215 # The format of each line is as follows
1217 # type source pattern
1218 # P/B/F T/F/O/S regex
1220 # type: P - private, B - bulletin (msg), F - file (ak1a bull)
1221 # source: T - to field, F - from field, O - origin, S - subject
1222 # pattern: a perl regex on the field requested
1224 # Currently only type B and P msgs are affected by this code.
1226 # The list is read from the top down, the first pattern that matches
1227 # causes the action to be taken.
1229 # The pattern can be undef or 0 in which case it will always be selected
1230 # for the action specified
1248 I think this is fairly self explanatory. It is simply a list of subject
1249 headers that we do not want to pass on to either the users of the cluster or
1250 the other cluster nodes that we are linked to. This is usually because of
1251 rules and regulations pertaining to items for sale etc in a particular country.
1253 <sect1>Filtering DX callouts (Depricated)
1256 <bf><it>From version 1.47, this method is replaced by the command set/baddx</it></bf>
1259 In the same way as mail, there are some types of spot we do not wish to pass on
1260 to users or linked cluster nodes. In the /spider/data directory you will find
1261 a file called baddx.pl.issue. Rename this to baddx.pl and edit the file. The
1262 original looks like this ....
1266 # the list of dx spot addresses that we don't store and don't pass on
1287 Again, this is simply a list of names we do not want to see in the spotted
1288 field of a DX callout.
1291 <sect1>Filtering words from text fields in Announce, Talk and DX spots
1294 Create a file in /spider/data called <em>badwords</em>. The format is quite
1295 simple. Lines beginning with # are ignored so comments can be added. An
1296 example file is below ...
1299 # Below is a list of words we do not wish to see on the cluster
1300 grunge grunged grunging
1301 splodge splodger splodging
1306 Multiple words can be used on the same line as shown. Obviously these
1307 are just examples :-)
1310 You can reload the file from the cluster prompt as sysop with load/badwords.
1315 DXSpider deals seamlessly with standard AK1A type mail. It supports both
1316 personal and bulletin mail and the sysop has additional commands to ensure
1317 that mail gets to where it is meant. DXSpider will send mail almost
1318 immediately, assuming that the target is on line. However, only one
1319 mail message is dealt with at any one time. If a mail message is already
1320 being sent or recieved, then the new message will be queued until it has
1323 The cluster mail is automatically deleted after 30 days unless the sysop
1324 sets the "keep" flag using the <em>msg</em> command.
1326 <sect1>Personal mail
1329 Personal mail is sent using the <em>sp</em> command. This is actually the
1330 default method of sending mail and so a simple <em>s</em> for send will do.
1331 A full list of the send commands and options is in the <em>command set</em>
1332 section, so I will not duplicate them here.
1334 <sect1>Bulletin mail
1337 Bulletin mail is sent by using the <em>sb</em> command. This is one of the
1338 most common mistakes users make when sending mail. They send a bulletin
1339 mail with <em>s</em> or <em>sp</em> instead of <em>sb</em> and of course
1340 the message never leaves the cluster. This can be rectified by the sysop
1341 by using the <em>msg</em> command.
1343 <P>Bulletin addresses can be set using the Forward.pl file.
1348 DXSpider receives all and any mail sent to it without any alterations needed
1349 in files. Because personal and bulletin mail are treated differently, there
1350 is no need for a list of accepted bulletin addresses. It is necessary, however,
1351 to tell the program which links accept which bulletins. For example, it is
1352 pointless sending bulletins addresses to "UK" to any links other than UK
1353 ones. The file that does this is called forward.pl and lives in /spider/msg.
1354 At default, like other spider files it is named forward.pl.issue. Rename it
1355 to forward.pl and edit the file to match your requirements.
1356 The format is below ...
1360 # this is an example message forwarding file for the system
1362 # The format of each line is as follows
1364 # type to/from/at pattern action destinations
1365 # P/B/F T/F/A regex I/F [ call [, call ...] ]
1367 # type: P - private, B - bulletin (msg), F - file (ak1a bull)
1368 # to/from/at: T - to field, F - from field, A - home bbs, O - origin
1369 # pattern: a perl regex on the field requested
1370 # action: I - ignore, F - forward
1371 # destinations: a reference to an array containing node callsigns
1373 # if it is non-private and isn't in here then it won't get forwarded
1375 # Currently only type B msgs are affected by this code.
1377 # The list is read from the top down, the first pattern that matches
1378 # causes the action to be taken.
1380 # The pattern can be undef or 0 in which case it will always be selected
1381 # for the action specified
1383 # If the BBS list is undef or 0 and the action is 'F' (and it matches the
1384 # pattern) then it will always be forwarded to every node that doesn't have
1385 # it (I strongly recommend you don't use this unless you REALLY mean it, if
1386 # you allow a new link with this on EVERY bull will be forwarded immediately
1387 # on first connection)
1393 'B', 'T', 'LOCAL', 'F', [ qw(GB7MBC) ],
1394 'B', 'T', 'ALL', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1395 'B', 'T', 'UK', 'F', [ qw(GB7BAA GB7ADX) ],
1396 'B', 'T', 'QSL', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1397 'B', 'T', 'QSLINF', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1398 'B', 'T', 'DX', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1399 'B', 'T', 'DXINFO', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1400 'B', 'T', 'DXNEWS', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1401 'B', 'T', 'DXQSL', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1402 'B', 'T', 'SYSOP', 'F', [ qw(GB7BAA GB7ADX) ],
1403 'B', 'T', '50MHZ', 'F', [ qw(GB7BAA GB7ADX PA4AB-14) ],
1407 Simply insert a bulletin address and state in the brackets where you wish
1408 that mail to go. For example, you can see here that mail sent to "UK" will
1409 only be sent to the UK links and not to PA4AB-14.
1412 To force the cluster to reread the file use load/forward
1415 <sect1>The msg command
1418 The <em>msg</em> command is a very powerful and flexible tool for the
1419 sysop. It allows the sysop to alter to and from fields and make other
1420 changes to manage the cluster mail.
1422 Here is a full list of the various options ...
1425 MSG TO <msgno> <call> - change TO callsign to <call>
1426 MSG FRom <msgno> <call> - change FROM callsign to <call>
1427 MSG PRrivate <msgno> - set private flag
1428 MSG NOPRrivate <msgno> - unset private flag
1429 MSG RR <msgno> - set RR flag
1430 MSG NORR <msgno> - unset RR flag
1431 MSG KEep <msgno> - set the keep flag (message won't be deleted ever)
1432 MSG NOKEep <msgno> - unset the keep flag
1433 MSG SUbject <msgno> <new> - change the subject to <new>
1434 MSG WAittime <msgno> - remove any waiting time for this message
1435 MSG NOREad <msgno> - mark message as unread
1436 MSG REad <msgno> - mark message as read
1437 MSG QUeue - queue any outstanding bulletins
1438 MSG QUeue 1 - queue any outstanding private messages
1441 These commands are simply typed from within the cluster as the sysop user.
1443 <sect1>Message status
1446 You can check on a message from within the cluster by using the command
1447 <em>stat/msg</em>. This will give you additional information on the
1448 message number including which nodes have received it, which node it
1449 was received from and when etc. Here is an example of the output of
1453 G0VGS de GB7MBC 28-Jan-2001 1308Z >
1456 Msg Time: 26-Jan-2001 1302Z
1460 Subject: AMSAT 2line KEPS 01025.AMSAT
1462 Got it Nodes: GB7BAA, GB7ADX
1466 G0VGS de GB7MBC 28-Jan-2001 1308Z >
1469 <sect1>Filtering mail
1472 This is described in the section on <em>Other filters</em> so I will not
1475 <sect1>Distribution lists
1478 Distribution lists are simply a list of users to send certain types of
1479 mail to. An example of this is mail you only wish to send to other
1480 sysops. In /spider/msg there is a directory called <em>distro</em>. You
1481 put any distibution lists in here. For example, here is a file called
1482 SYSOP.pl that caters for the UK sysops.
1485 qw(GB7TLH GB7DJK GB7DXM GB7CDX GB7BPQ GB7DXN GB7MBC GB7MBC-6 GB7MDX
1486 GB7NDX GB7SDX GB7TDX GB7UDX GB7YDX GB7ADX GB7BAA GB7DXA GB7DXH
1487 GB7DXK GB7DXI GB7DXS)
1490 Any mail sent to "sysop" would only be sent to the callsigns in this list.
1492 <sect1>BBS interface
1495 Spider provides a simple BBS interface. No input is required from the sysop
1496 of the cluster at all. The BBS simply sets the cluster as a BBS and pushes
1497 any required mail to the cluster. No mail can flow from Spider to the BBS,
1498 the interface is one-way.
1501 Please be careful not to flood the cluster network with unnecessary mail.
1502 Make sure you only send mail to the clusters that want it by using the
1503 Forward.pl file very carefully.
1508 Spider allows the creation of local or remote databases. It supports
1509 chained databases, allowing several different databases to be scanned
1510 with one simple command. Importing of databases is limited at present
1511 to the standard AK1A databases such as OBLAST and the DB0SDX QSL
1512 database but will expand with time.
1514 <sect1>Creating databases
1517 Creating a database could not be more simple. All the commands are
1518 sent from the cluster prompt as the <em>sysop</em> user.
1520 To create a database you use the command <em>dbcreate</em>. It can
1521 be used in 3 different ways like so ..
1527 To simply create a database locally, you just tell the command the
1528 name of the database. This does not create the actual database, it
1529 simply defines it to say that it exists.
1532 dbcreate <name> chain <name> [<name>...]
1535 This creates a chained database entry. The first database will be
1536 scanned, then the second, the third etc...
1539 dbcreate <name> remote <name>
1542 This creates a remote entry. the first name field is the database
1543 name at the remote node, then the remote switch, then the actual
1544 node_call of the remote node, for example...
1547 dbcreate buckmaster remote gb7dxc
1550 Remote databases cannot be chained, however, the last database in a
1551 chain can be a remote database.
1553 <sect1>Importing databases
1556 The only databases that Spider can currently import are the standard
1557 AK1A databases such as OBLAST or the DB0SDX qsl and address database.
1558 This will be added to with time.
1560 To import such a database, first put the file somewhere useful like /tmp
1561 and then issue the following command ...
1564 dbimport oblast /tmp/OBLAST.FUL
1567 This will update the existing local oblast database or create it if
1570 <sect1>Checking available databases
1573 Once a database is created, you will want to check that it has been
1574 added. To do this use the <em>dbavail</em> command. This will
1575 output the available databases. For example ...
1579 DB Name Location Chain
1583 G0VGS de GB7MBC 3-Feb-2001 1925Z >
1586 <sect1>Looking up databases
1589 To look for information in a defined database, simply use the <em>dbshow</em>
1590 command, for example ...
1593 dbshow buckmaster G0YLM
1596 will show the information for the callsign G0YLM from the buckmaster
1597 database if it exists. To make things more standard for the users
1598 you can add an entry in the Aliases file so that it looks like a standard
1599 <em>show</em> command like this ...
1602 '^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
1605 Now you can simply use show/buckmaster or an abreviation.
1607 <sect1>Removing databases
1610 To delete an existing database you use the <em>dbremove</em> command.
1617 would remove the oblast database and its associated datafile from the
1618 system. There are no warnings or recovery possible from this command.
1619 If you remove a database it ceases to exist and would have to be created
1620 from scratch if you still required it.
1622 <sect>Information, files and useful programs
1627 One of the more important things a cluster sysop needs to do is to get
1628 information to his users. The simplest way to do this is to have a banner
1629 that is sent to the user on login. This is know as a "message of the day"
1630 or "motd". To set this up, simply create a file in /spider/data called motd
1631 and edit it to say whatever you want. It is purely a text file and will be
1632 sent automatically to anyone logging in to the cluster.
1634 <sect1>Downtime message
1637 If for any reason the cluster is down, maybe for upgrade or maintenance but
1638 the machine is still running, a message can be sent to the user advising them
1639 of the fact. This message lives in the /spider/data directory and is called
1640 "offline". Simply create the file and edit it to say whatever you wish.
1641 This file will be sent to a user attempting to log into the cluster when
1642 DXSpider is not actually running.
1644 <sect1>Other text messages
1647 You can set other text messages to be read by the user if they input the file
1648 name. This could be for news items or maybe information for new users.
1649 To set this up, make a directory under /spider called <em>packclus</em>.
1650 Under this directory you can create files called <em>news</em> or <em>newuser</em>
1651 for example. In fact you can create files with any names you like. These can
1652 be listed by the user with the command ....
1658 They can be read by the user by typing the command ....
1664 If the file they want to read is called <em>news</em>. You could also set
1665 an alias for this in the Alias file to allow them just to type <em>news</em>
1668 You can also store other information in this directory, either directly or
1669 nested under directories. One use for this would be to store DX bulletins
1670 such as the OPDX bulletins. These can be listed and read by the user.
1671 To keep things tidy, make a directory under /spider/packclus called
1672 <em>bulletins</em>. Now copy any OPDX or similar bulletins into it. These
1673 can be listed by the user in the same way as above using the <em>show/files</em>
1674 command with an extension for the bulletins directory you have just created,
1678 show/files bulletins
1682 An example would look like this ....
1686 bulletins DIR 20-Dec-1999 1715Z news 1602 14-Dec-1999 1330Z
1689 You can see that in the files area (basically the packclus directory) there is a
1690 file called <em>news</em> and a directory called <em>bulletins</em>. You can
1691 also see that dates they were created. In the case of the file <em>news</em>,
1692 you can also see the time it was last modified, a good clue as to whether the
1693 file has been updated since you last read it. To read the file called
1694 <em>news</em> you would simply issue the command ....
1700 To look what is in the bulletins directory you issue the command ....
1703 show/files bulletins

1883 You can create aliases for commands at will. Beware though, these may not
1884 always turn out as you think. Care is needed and you need to test the
1885 results once you have set an alias.
1890 In later versions of Spider a simple console program is provided for the sysop.
1891 This has a type ahead buffer with line editing facilities and colour for spots,
1892 announces etc. To use this program, simply use console.pl instead of client.pl.
1895 To edit the colours, copy /spider/perl/Console.pl to /spider/local and edit the
1896 file with your favourite editor.
1898 <sect1>Updating kepler data
1901 Spider has a powerful and flexible show/satellite command. In order for
1902 this to be accurate, the kepler data has to be updated regularly. In
1903 general, this data is available as an email or via cluster mail.
1904 Updating it is simple. First you need to export the mail message as a
1905 file. You do this with the <em>export</em> command from the cluster prompt
1906 as the sysop. For example ...
1909 export 5467 /spider/perl/keps.in
1912 would export message number 5467 as a file called keps.in in the
1913 /spider/perl directory.
1915 Now login to a VT as sysop and cd /spider/perl. There is a command in
1916 the perl directory called <em>convkeps.pl</em>. All we need to do now is
1917 convert the file like so ...
1920 ./convkeps.pl keps.in
1923 Now go back to the cluster and issue the command ...
1929 That is it! the kepler data has been updated.
1935 CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
1936 at <htmlurl url="http://www.sourceforge.net" name="Sourceforge">. This means
1937 that it is possible to update your DXSpider installation to the latest
1938 sources by using a few simple commands.
1941 THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
1942 INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
1943 THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
1944 YOU HAVE BEEN WARNED!!!
1947 DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
1951 I am of course assuming that you have a machine with both DXSpider and
1952 Internet access running.
1955 BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
1956 ENTIRE SPIDER TREE!!
1959 Assuming you are connected to the Internet, you need to login to the
1960 CVS repository and then update your Spider source. There are several
1961 steps which are listed below ...
1964 First login as the user <em>sysop</em>. Next you need to connect to the CVS
1965 repository. You do this with the command below ...
1968 cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
1971 You will get a password prompt. Simply hit return here and your machine should
1972 return to a normal linux prompt.
1975 What happens next depends on whether you have an existing installation that
1976 you want to update with the latest and greatest or whether you just want
1977 to see what is there and/or run it on a new machine for testing.
1978 Either way you will want to change directory to a new place, if you want to
1979 update an existing installation then I suggest /tmp, otherwise choose a
1980 suitable place according to the normal installation instructions.
1983 The next step will create a brand new 'spider' directory in your current
1987 cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
1990 This command is all on one line.
1993 Hopefully your screen should show you downloading files. The -z3 simply compresses
1994 the download to improve speed.
1995 When this has finished, you will have exactly the same as if you had untarred a full
1996 tarball PLUS some extra directories and files that CVS needs to do the magic that
2000 Now if you are doing a new installation, that's it. Carry on as if you have
2001 just downloaded and untarred the lastest tarball.
2004 If you want to upgrade your current installation then do this ...
2007 tar cvfz /tmp/s.tgz spider
2009 tar xvfzp /tmp/s.tgz
2012 This is assuming you downloaded to the /tmp directory of course.
2015 NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
2016 correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
2018 Remember to recompile the C client (cd /spider/src; make)
2021 At this point the files have been upgraded. You can (usually) restrt the cluster
2022 in your own time. However, if you attempt to use any new commands or features
2023 expect it to be fatal! At least your cluster will have been restarted then so it
2024 will be too late to worry about it!
2027 Now the magic part! From now on when you want to update, simply connect to the
2028 Internet and then, as the user <em>sysop</em> ...
2035 and your files will be updated. As above, remember to recompile the "C" client
2036 if it has been updated (CVS will tell you) and restart if any of the perl scripts
2037 have been altered or added, again, CVS will tell you.
2040 You will find any changes documented in the /spider/Changes file.
2042 <sect>The DXSpider command set
2045 Below is a complete list of commands available from the cluster prompt.
2046 Most maintenance tasks are automatic but there are some commands that are useful
2047 for a sysop. These are listed below in alphabetical order. The number in
2048 brackets following the command name is the permissions level needed to use
2051 <sect1>accept/announce (0)
2055 <bf>accept/announce [0-9] <pattern></bf> Set an accept filter
2060 Create an 'accept this announce' line for a filter.
2062 An accept filter line means that if the announce matches this filter it is
2063 passed onto the user. See HELP FILTERS for more info. Please read this
2064 to understand how filters work - it will save a lot of grief later on.
2066 You can use any of the following things in this line:-
2069 info <string> eg: iota or qsl
2070 by <prefixes> eg: G,M,2
2072 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
2073 origin_itu <numbers>
2074 origin_zone <numbers>
2079 wx 1 filter WX announces
2080 dest <prefixes> eg: 6MUK,WDX (distros)
2087 acc/ann 2 by_zone 14,15,16
2088 (this could be all on one line: acc/ann dest 6MUK or by_zone 14,15,16)
2097 This filter would only allow announces that were posted buy UK stations.
2098 You can use the tag 'all' to accept everything eg:
2104 but this probably for advanced users...
2106 <sect1>accept/announce (extended for sysops) (8)
2110 <bf>accept/announce <call> [input] [0-9]<pattern></bf> Announce filter sysop version
2114 This version allows a sysop to set a filter for a callsign as well as the
2115 default for nodes and users eg:-
2119 accept/ann input node_default by G,M,2
2120 accept/ann user_default by G,M,2
2123 <sect1>accept/spots (0)
2127 <bf>accept/announce [0-9] <pattern></bf> Set an accept filter
2132 Create an 'accept this spot' line for a filter.
2135 An accept filter line means that if the spot matches this filter it is
2136 passed onto the user. See HELP FILTERS for more info. Please read this
2137 to understand how filters work - it will save a lot of grief later on.
2139 You can use any of the following things in this line:-
2142 freq <range> eg: 0/30000 or hf or hf/cw or 6m,4m,2m
2143 on <range> same as 'freq'
2144 call <prefixes> eg: G,PA,HB9
2145 info <string> eg: iota or qsl
2147 call_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
2158 For frequencies, you can use any of the band names defined in
2159 SHOW/BANDS and you can use a subband name like: cw, rtty, data, ssb -
2160 thus: hf/ssb. You can also just have a simple range like: 0/30000 -
2161 this is more efficient than saying simply: freq HF (but don't get
2162 too hung up about that)
2168 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
2171 You can use the tag 'all' to accept everything, eg:
2177 but this probably for advanced users...
2179 <sect1>accept/spots (extended for sysops) (8)
2183 <bf>accept/spots <call> [input] [0-9] <pattern></bf> Spot filter sysop version
2187 This version allows a sysop to set a filter for a callsign as well as the
2188 default for nodes and users eg:-
2191 accept/spot db0sue-7 1 by_zone 14,15,16
2192 accept/spot node_default all
2193 set/hops node_default 10
2195 accept/spot user_default by G,M,2
2198 <sect1>accept/wcy (0)
2202 <bf>accept/wcy [0-9] <pattern></bf> set an accept WCY filter
2206 It is unlikely that you will want to do this, but if you do then you can
2207 filter on the following fields:-
2210 by <prefixes> eg: G,M,2
2212 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
2213 origin_itu <numbers>
2214 origin_zone <numbers>
2222 There are no examples because WCY Broadcasts only come from one place and
2223 you either want them or not (see UNSET/WCY if you don't want them).
2225 This command is really provided for future use.
2227 See HELP FILTER for information.
2229 <sect1>accept/wcy (extended for sysops) (8)
2233 <bf>accept/wcy <call> [input] [0-9] <pattern></bf>
2234 WCY filter sysop version
2238 This version allows a sysop to set a filter for a callsign as well as the
2239 default for nodes and users eg:-
2242 accept/wcy node_default all
2243 set/hops node_default 10
2246 <sect1>accept/wwv (0)
2250 <bf>accept/wwv [0-9] <pattern></bf> Set an accept WWV filter
2254 It is unlikely that you will want to do this, but if you do then you can
2255 filter on the following fields:-
2258 by <prefixes> eg: G,M,2
2260 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
2261 origin_itu <numbers>
2262 origin_zone <numbers>
2272 accept/wwv by_zone 4
2275 is probably the only useful thing to do (which will only show WWV broadcasts
2276 by stations in the US).
2278 See HELP FILTER for information.
2280 <sect1>accept/wwv (extended for sysops) (8)
2284 <bf>accept/wwv <call> [input] [0-9] <pattern></bf>
2285 WWV filter sysop version
2289 This version allows a sysop to set a filter for a callsign as well as the
2290 default for nodes and users eg:-
2293 accept/wwv db0sue-7 1 by_zone 4
2294 accept/wwv node_default all
2295 set/hops node_default 10
2297 accept/wwv user_default by W,K
2304 <bf>announce <text></bf> Send an announcement to local users
2308 Send an announcement to LOCAL users only, where <text> is the text
2309 of the announcement you wish to broadcast
2311 <sect1>announce full (0)
2315 <bf>announce full <text></bf> Send an announcement cluster wide
2319 This command will send your announcement across the whole cluster
2323 <sect1>announce sysop (5)
2327 <bf>announce sysop <text></bf>
2331 Send an announcement to Sysops only
2337 <bf>apropos <string></bf> Search the help database
2341 Search the help database for <string> (it isn't case sensitive),
2342 and print the names of all the commands that may be relevant.
2348 <bf>bye</bf> Exit from the cluster
2352 This will disconnect you from the cluster
2358 <bf>catchup <node_call> All|[<msgno> ...]</bf>
2359 Mark a message as sent
2363 When you send messages the fact that you have forwarded it to another node
2364 is remembered so that it isn't sent again. When you have a new partner
2365 node and you add their callsign to your /spider/msg/forward.pl file, all
2366 outstanding non-private messages will be forwarded to them. This may well
2367 be ALL the non-private messages. You can prevent this by using these
2372 catchup GB7DJK 300 301 302 303 500-510
2375 and to undo what you have just done:-
2378 uncatchup GB7DJK all
2379 uncatchup GB7DJK 300 301 302 303 500-510
2382 which will arrange for them to be forward candidates again.
2384 Order is not important.
2386 <sect1>clear/spots (0)
2390 <bf>clear/spots [1|all]</bf> Clear a spot filter line
2394 This command allows you to clear (remove) a line in a spot filter or to
2395 remove the whole filter.
2397 If you have a filter:-
2401 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
2410 you will be left with:-
2413 acc/spot 2 on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
2422 the filter will be completely removed.
2429 <bf>connect <callsign></bf> Start a connection to another DX Cluster
2433 Start a connection process that will culminate in a new connection to the
2434 DX cluster <callsign>. This process creates a new 'client' process which will
2435 use the script in /spider/connect/<callsign> to effect the 'chat' exchange
2436 necessary to traverse the network(s) to logon to the cluster <callsign>.
2442 <bf>dbavail</bf> Show a list of all the databases in the system
2446 The title says it all really, this command lists all the databases defined
2447 in the system. It is also aliased to SHOW/COMMAND.
2453 <bf>dbcreate <name></bf> Create a database entry<newline>
2454 <bf>dbcreate <name> chain <name> [<name>..]</bf> Create a
2455 chained database entry<newline>
2456 <bf>dbcreate <name> remote <node></bf> Create a remote database
2461 DBCREATE allows you to define a database in the system. It doesn't actually
2462 create anything, just defines it.
2464 The databases that are created are simple DB_File hash databases, they are
2465 therefore already 'indexed'.
2467 You can define a local database with the first form of the command eg:
2471 You can also chain databases with the addition of the 'chain' keyword.
2472 This will search each database one after the other. A typical example
2475 DBCREATE sdx_qsl chain sql_ad
2477 No checking is done to see if the any of the chained databases exist, in
2478 fact it is usually better to do the above statement first then do each of
2479 the chained databases.
2481 Databases can exist offsite. To define a database that lives on another
2484 DBCREATE buckmaster remote gb7dxc
2486 Remote databases cannot be chained; however, the last database in a
2487 a chain can be a remote database eg:
2489 DBCREATE qsl chain gb7dxc
2491 To see what databases have been defined do:
2493 DBAVAIL (or it will have been aliased to SHOW/COMMAND)
2495 It would be normal for you to add an entry into your local Aliases file
2496 to allow people to use the 'SHOW/<dbname>' style syntax. So you would
2497 need to add a line like:-
2503 '^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
2513 to work as they may be used to.
2515 See DBIMPORT for the importing of existing AK1A format data to databases.
2516 See DBSHOW for generic database enquiry
2522 <bf>dbimport <dbname></bf> Import AK1A data into a database
2526 If you want to import or update data in bulk to a database you can use
2527 this command. It will either create or update entries into an existing
2528 database. For example:-
2530 DBIMPORT oblast /tmp/OBLAST.FUL
2532 will import the standard OBLAST database that comes with AK1A into the
2533 oblast database held locally.
2539 <bf>dbremove <dbname></bf> Delete a database
2543 DBREMOVE will completely remove a database entry and also delete any data
2544 file that is associated with it.
2546 There is no warning, no comeback, no safety net.
2552 will remove the oblast database from the system and it will also remove
2553 the associated datafile.
2557 There is no warning, no comeback, no safety net.
2559 You have been warned.
2565 <bf>dbshow <dbname> <key></bf> Display an entry, if it exists,
2570 This is the generic user interface to the database to the database system.
2571 It is expected that the sysop will add an entry to the local Aliases file
2572 so that users can use the more familiar AK1A style of enquiry such as:
2578 but if he hasn't and the database really does exist (use DBAVAIL or
2579 SHOW/COMMAND to find out) you can do the same thing with:
2590 <bf>debug</bf> Set the cluster program into debug mode
2594 Executing this command will only have an effect if you are running the cluster
2601 It will interrupt the cluster just after the debug command has finished.
2603 <sect1>directory (0)
2607 <bf>directory</bf> List messages<newline>
2608 <bf>directory all</bf> List all messages<newline>
2609 <bf>directory own</bf> List your own messages<newline>
2610 <bf>directory new</bf> List all new messages<newline>
2611 <bf>directory to <call></bf> List all messages to <call><newline>
2612 <bf>directory from <call></bf> List all messages from <call><newline>
2613 <bf>directory subject <string></bf> List all messages with <string>
2615 <bf>directory <nn></bf> List last <nn> messages<newline>
2616 <bf>directory <from>-<to></bf> List messages <from> message <to> message <newline>
2620 List the messages in the messages directory.
2622 If there is a 'p' one space after the message number then it is a
2623 personal message. If there is a '-' between the message number and the
2624 'p' then this indicates that the message has been read.
2626 You can use shell escape characters such as '*' and '?' in the <call>
2629 You can combine some of the various directory commands together eg:-
2634 DIR SUBJECT IOTA 200-250
2637 You can abbreviate all the commands to one letter and use ak1a syntax:-
2645 <sect1>directory (extended for sysops) (5)
2648 Works just like the user command except that sysops can see ALL messages.
2650 <sect1>disconnect (8)
2654 <bf>disconnect <call> [<call> ...]</bf> Disconnect a user or node
2658 Disconnect any <call> connected locally
2664 <bf>dx [by <call>] <freq> <call> <remarks></bf> Send a DX spot
2668 This is how you send a DX Spot to other users. You can, in fact, now
2669 enter the <freq> and the <call> either way round.
2677 will all give the same result. You can add some remarks to the end
2678 of the command and they will be added to the spot.
2681 DX FR0G 144600 this is a test
2684 You can credit someone else by saying:-
2687 DX by G1TLH FR0G 144.600 he isn't on the cluster
2690 The <freq> is compared against the available bands set up in the
2691 cluster. See SHOW/BANDS for more information.
2697 <bf>export <msgno> <filename></bf> Export a message to a file
2701 Export a message to a file. This command can only be executed on a local
2702 console with a fully privileged user. The file produced will be in a form
2703 ready to be imported back into the cluster by placing it in the import
2704 directory (/spider/msg/import).
2706 This command cannot overwrite an existing file. This is to provide some
2707 measure of security. Any files written will owned by the same user as the
2708 main cluster, otherwise you can put the new files anywhere the cluster can
2709 access. For example:-
2713 <sect1>export_users (9)
2717 <bf>export_users [<filename>]</bf> Export the users database to ascii
2721 Export the users database to a file in ascii format. If no filename
2722 is given then it will export the file to /spider/data/user_asc.
2724 If the file already exists it will be renamed to <filename>.o. In fact
2725 up to 5 generations of the file can be kept each one with an extra 'o' on the
2728 BE WARNED: this will write to any file you have write access to. No check is
2729 made on the filename (if any) that you specify.
2731 <sect1>forward/latlong (8)
2735 <bf>forward/latlong <node_call></bf> Send latitude and longitude
2736 information to another cluster
2740 This command sends all the latitude and longitude information that your
2741 cluster is holding against callsigns. One advantage of recieving this
2742 information is that more locator information is held by you. This
2743 means that more locators are given on the DX line assuming you have
2744 <em>set/dxgrid</em> enabled. This could be a LOT of information though, so
2745 it is not recommended on slow links.
2747 <sect1>forward/opername (1)
2751 <bf>forward/opername <call></bf> Send out information on this <call>
2756 This command sends out any information held in the user file which can
2757 be broadcast in PC41 protocol packets. This information is Name, QTH, Location
2758 and Homenode. PC41s are only sent for the information that is available.
2764 <bf>help <cmd></bf> Get help on a command
2768 All commands can be abbreviated, so SHOW/DX can be abbreviated
2769 to SH/DX, ANNOUNCE can be shortened to AN and so on.
2771 Look at the APROPOS <string> command which will search the help database
2772 for the <string> you specify and give you a list of likely commands
2773 to look at with HELP.
2779 <bf>init <node call></bf> Re-initialise a link to an AK1A compatible node
2783 This command attempts to re-initialise a link to a (usually) AK1A node
2784 that has got confused, usually by a protocol loop of some kind. It may
2785 work - but you usually will be better off simply disconnecting it (or
2786 better, if it is a real AK1A node, doing an RCMD <node> DISC/F <your
2789 Best of luck - you will need it.
2795 <bf>kill <msgno> [<msgno> ..]</bf> Delete a message
2796 from the local system
2800 Delete a message from the local system. You will only be able to
2801 delete messages that you have originated or been sent (unless you are
2808 <bf>kill <msgno> [<msgno> ...]</bf> Remove or erase a message from
2810 <bf>kill from <call></bf> Remove all messages from a callsign<newline>
2811 <bf>kill to <call></bf> Remove all messages to a callsign<newline>
2815 You can get rid of any message to or originating from your callsign using
2816 this command. You can remove more than one message at a time.
2818 As a sysop you can kill any message on the system.
2820 <sect1>kill full (5)
2824 <bf>kill full <msgno> [<msgno>]</bf> Delete a message from the
2829 Delete a message (usually a 'bulletin') from the whole cluster system.
2831 This uses the subject field, so any messages that have exactly the same subject
2832 will be deleted. Beware!
2838 <bf>links</bf> Show which nodes are physically connected
2842 This is a quick listing that shows which links are connected and
2843 some information about them. See WHO for a list of all connections.
2846 <sect1>load/aliases (9)
2850 <bf>load/aliases</bf> Reload the command alias table
2854 Reload the /spider/cmd/Aliases file after you have editted it. You will need to
2855 do this if you change this file whilst the cluster is running in order for the
2856 changes to take effect.
2859 <sect1>load/baddx (9)
2863 <bf>load/baddx</bf> Reload the bad DX table
2867 Reload the /spider/data/baddx.pl file if you have changed it manually whilst
2868 the cluster is running. This table contains the DX Calls that, if spotted,
2869 will not be passed on. FR0G and TEST are classic examples.
2871 <sect1>load/badmsg (9)
2875 <bf>load/badmsg</bf> Reload the bad message table
2879 Reload the /spider/msg/badmsg.pl file if you have changed it manually whilst
2880 the cluster is running. This table contains a number of perl regular
2881 expressions which are searched for in the fields targetted of each message.
2882 If any of them match then that message is immediately deleted on receipt.
2884 <sect1>load/badwords (9)
2888 <bf>load/badwords</bf> Reload the badwords file
2892 Reload the /spider/data/badwords file if you have changed it manually whilst
2893 the cluster is running. This file contains a list of words which, if found
2894 on certain text portions of PC protocol, will cause those protocol frames
2895 to be rejected. It will all put out a message if any of these words are
2896 used on the announce, dx and talk commands. The words can be one or
2897 more on a line, lines starting with '#' are ignored.
2899 <sect1>load/bands (9)
2903 <bf>load/bands</bf> Reload the band limits table
2907 Reload the /spider/data/bands.pl file if you have changed it manually whilst
2908 the cluster is running.
2910 <sect1>load/cmd_cache (9)
2914 <bf>load/cmd_cache</bf> Reload the automatic command cache
2918 Normally, if you change a command file in the cmd or local_cmd tree it will
2919 automatially be picked up by the cluster program. Sometimes it can get confused
2920 if you are doing a lot of moving commands about or delete a command in the
2921 local_cmd tree and want to use the normal one again. Execute this command to
2922 reset everything back to the state it was just after a cluster restart.
2924 <sect1>load/forward (9)
2928 <bf>load/forward</bf> Reload the msg forwarding routing table
2931 Reload the /spider/msg/forward.pl file if you have changed it
2932 manually whilst the cluster is running.
2934 <sect1>load/messages (9)
2938 <bf>load/messages</bf> Reload the system messages file
2942 If you change the /spider/perl/Messages file (usually whilst fiddling/writing ne
2943 commands) you can have them take effect during a cluster session by executing this
2944 command. You need to do this if get something like :-
2946 unknown message 'xxxx' in lang 'en'
2948 <sect1>load/prefixes (9)
2952 <bf>load/prefixes</bf> Reload the prefix table
2956 Reload the /spider/data/prefix_data.pl file if you have changed it manually
2957 whilst the cluster is running.
2963 <bf>merge <node> [<no spots>/<no wwv>]</bf> Ask for the
2964 latest spots and WWV
2968 MERGE allows you to bring your spot and wwv database up to date. By default
2969 it will request the last 10 spots and 5 WWVs from the node you select. The
2970 node must be connected locally.
2972 You can request any number of spots or wwv and although they will be appended
2973 to your databases they will not duplicate any that have recently been added
2974 (the last 2 days for spots and last month for WWV data).
2980 <bf>msg <cmd> <msgno> [data ...]</bf> Alter various message
2985 Alter message parameters like To, From, Subject, whether private or bulletin
2986 or return receipt (RR) is required or whether to keep this message from timing
2990 MSG TO <msgno> <call> - change TO callsign to <call>
2991 MSG FRom <msgno> <call> - change FROM callsign to <call>
2992 MSG PRrivate <msgno> - set private flag
2993 MSG NOPRrivate <msgno> - unset private flag
2994 MSG RR <msgno> - set RR flag
2995 MSG NORR <msgno> - unset RR flag
2996 MSG KEep <msgno> - set the keep flag (message won't be deleted ever)
2997 MSG NOKEep <msgno> - unset the keep flag
2998 MSG SUbject <msgno> <new> - change the subject to <new>
2999 MSG WAittime <msgno> - remove any waitting time for this message
3000 MSG NOREad <msgno> - mark message as unread
3001 MSG REad <msgno> - mark message as read
3002 MSG QUeue - queue any outstanding bulletins
3003 MSG QUeue 1 - queue any outstanding private messages
3006 You can look at the status of a message by using:-
3008 STAT/MSG <msgno>
3010 This will display more information on the message than DIR does.
3016 <bf>pc <call> <text></bf> Send text (eg PC Protocol) to <call>
3020 Send some arbitrary text to a locally connected callsign. No processing is done on
3021 the text. This command allows you to send PC Protocol to unstick things if problems
3022 arise (messages get stuck etc). eg:-
3024 pc gb7djk PC33^GB7TLH^GB7DJK^400^
3026 You can also use in the same way as a talk command to a connected user but
3027 without any processing, added of "from <blah> to <blah>" or whatever.
3029 pc G1TLH Try doing that properly!!!
3035 <bf>ping <node></bf> Check the link quality between nodes
3039 his command allows you to send a frame to another cluster node on
3040 the network and get a return frame. The time it takes to do this
3041 is a good indication of the quality of the link. The actual time
3042 it takes is output to the console in seconds.
3043 Any visible cluster node can be PINGed.
3050 <bf>rcmd <node call> <cmd></bf> Send a command to another DX cluster
3054 This command allows you to send nearly any command to another DX Cluster
3055 node that is connected to the system.
3057 Whether you get any output is dependant on a) whether the other system knows
3058 that the node callsign of this cluster is in fact a node b) whether the
3059 other system is allowing RCMDs from this node and c) whether you have
3060 permission to send this command at all.
3066 <bf>read</bf> Read the next unread personal message addressed to you<newline>
3067 <bf>read <msgno></bf> Read the specified message<newline>
3071 You can read any messages that are sent as 'non-personal' and also any
3072 message either sent by or sent to your callsign.
3075 <sect1>read (extended for sysops) (5)
3079 <bf>read <msgno></bf> Read a message on the system
3083 As a sysop you may read any message on the system
3085 <sect1>reject/announce
3089 <bf>reject/announce [0-9] <pattern></bf> Set a reject filter
3094 Create an 'reject this announce' line for a filter.
3096 An reject filter line means that if the announce matches this filter it is
3097 passed onto the user. See HELP FILTERS for more info. Please read this
3098 to understand how filters work - it will save a lot of grief later on.
3100 You can use any of the following things in this line:-
3103 info <string> eg: iota or qsl
3104 by <prefixes> eg: G,M,2
3106 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
3107 origin_itu <numbers>
3108 origin_zone <numbers>
3113 wx 1 filter WX announces
3114 dest <prefixes> eg: 6MUK,WDX (distros)
3120 rej/ann by_zone 14,15,16 and not by G,M,2
3123 You can use the tag 'all' to reject everything eg:
3129 but this probably for advanced users...
3131 <sect1>reject/announce (extended for sysops) (8)
3135 <bf>reject/announce <call> [input] [0-9] <pattern></bf> Announce filter sysop version
3139 This version allows a sysop to set a filter for a callsign as well as the
3140 default for nodes and users eg:-
3144 reject/ann input node_default by G,M,2
3145 reject/ann user_default by G,M,2
3148 <sect1>reject/spots (0)
3152 <bf>reject/spots [0-9] <pattern></bf> Set a reject filter
3157 Create a 'reject this spot' line for a filter.
3159 A reject filter line means that if the spot matches this filter it is
3160 dumped (not passed on). See HELP FILTERS for more info. Please read this
3161 to understand how filters work - it will save a lot of grief later on.
3163 You can use any of the following things in this line:-
3166 freq <range> eg: 0/30000 or hf or hf/cw or 6m,4m,2m
3167 on <range> same as 'freq'
3168 call <prefixes> eg: G,PA,HB9
3169 info <string> eg: iota or qsl
3171 call_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
3181 For frequencies, you can use any of the band names defined in
3182 SHOW/BANDS and you can use a subband name like: cw, rtty, data, ssb -
3183 thus: hf/ssb. You can also just have a simple range like: 0/30000 -
3184 this is more efficient than saying simply: on HF (but don't get
3185 too hung up about that)
3191 rej/spot 2 on vhf and not (by_zone 14,15,16 or call_zone 14,15,16)
3194 You can use the tag 'all' to reject everything eg:
3200 but this probably for advanced users...

3206 <bf>reject/spots <call> [input] [0-9] <pattern></bf>
3207 Reject spot filter sysop version
3211 This version allows a sysop to set a filter for a callsign as well as the
3212 default for nodes and users eg:-
3215 reject/spot db0sue-7 1 by_zone 14,15,16
3216 reject/spot node_default all
3217 set/hops node_default 10
3219 reject/spot user_default by G,M,2
3222 <sect1>reject/wcy (0)
3226 <bf>reject/wcy [0-9] <pattern></bf> Set a reject WCY filter
3230 It is unlikely that you will want to do this, but if you do then you can
3231 filter on the following fields:-
3234 by <prefixes> eg: G,M,2
3236 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
3237 origin_itu <numbers>
3238 origin_zone <numbers>
3245 There are no examples because WCY Broadcasts only come from one place and
3246 you either want them or not (see UNSET/WCY if you don't want them).
3248 This command is really provided for future use.
3250 See HELP FILTER for information.

3256 <bf>reject/wcy <call> [input] [0-9] <pattern></bf>
3257 WCY reject filter sysop version
3261 This version allows a sysop to set a filter for a callsign as well as the
3262 default for nodes and users eg:-
3264 reject/wcy gb7djk all
3266 <sect1>reject/wwv (0)
3270 <bf>reject/wwv [0-9] <pattern></bf> Set a reject WWV filter
3274 It is unlikely that you will want to do this, but if you do then you can
3275 filter on the following fields:-
3278 by <prefixes> eg: G,M,2
3280 origin_dxcc <numbers> eg: 61,62 (from eg: sh/pre G)
3281 origin_itu <numbers>
3282 origin_zone <numbers>
3292 reject/wwv by_zone 14,15,16
3295 is probably the only useful thing to do (which will only show WWV broadcasts
3296 by stations in the US).

3332 You can reply to a message and the subject will automatically have
3333 "Re:" inserted in front of it, if it isn't already present.
3335 You can also use all the extra qualifiers such as RR, PRIVATE,
3336 NOPRIVATE, B that you can use with the SEND command (see SEND
3337 for further details)
3343 <bf>send <call> [<call> ...]</bf> Send a message to
3344 one or more callsigns<newline>
3345 <bf>send RR <call></bf> Send a message and ask for a read receipt<newline>
3346 <bf>send COPY <msgno> <call></bf> Send a copy of a message
3348 <bf>send PRIVATE <call></bf> Send a personal message<newline>
3349 <bf>send NOPRIVATE <call></bf> Send a message to all stations<newline>
3353 All the SEND commands will create a message which will be sent either to
3354 an individual callsign or to one of the 'bulletin' addresses.
3356 SEND <call> on its own acts as though you had typed SEND PRIVATE, that is
3357 it will mark the message as personal and send it to the cluster node that
3358 that callsign is connected to.
3360 You can have more than one callsign in all of the SEND commands.
3362 You can have multiple qualifiers so that you can have for example:-
3365 SEND RR COPY 123 PRIVATE G1TLH G0RDI
3368 which should send a copy of message 123 to G1TLH and G0RDI and you will
3369 receive a read receipt when they have read the message.
3371 SB is an alias for SEND NOPRIVATE (or send a bulletin in BBS speak)
3372 SP is an alias for SEND PRIVATE
3374 <sect1>set/address (0)

3403 Set the node_call as an AR-Cluster type node
3405 <sect1>set/baddx (8)
3409 <bf>set/baddx <call></bf> Stop words we do not wish to see in the callsign field
3410 of a dx spot being propagated
3414 Setting a word as 'baddx' will prevent spots with that word in the callsign
3415 field of a DX spot from going any further. They will not be displayed and they
3416 will not be sent onto other nodes.
3418 The word must be wriiten in full, no wild cards are allowed eg:-
3421 set/baddx FORSALE VIDEO FR0G
3424 To allow a word again, use the following command ...
3430 <sect1>set/badnode (6)
3434 <bf>set/badnode <node_call></bf> Stop spots from this node_call
3439 Setting a callsign as a 'badnode' will prevent spots from that node
3440 going any further. They will not be displayed and they will not be
3441 sent onto other nodes.
3443 The call can be a full or partial call (or a prefix), eg:-
3449 will stop anything from K1TTT (including any SSID's)
3455 will allow spots from him again.
3457 Use with extreme care. This command may well be superceded by FILTERing.
3459 <sect1>set/badspotter (8)
3463 <bf>set/badspotter <call></bf> Stop spots from this callsign being propagated
3467 Setting a callsign as a 'badspotter' will prevent spots from this callsign
3468 going any further. They will not be displayed and they will not be
3469 sent onto other nodes.
3471 The call must be written in full, no wild cards are allowed eg:-
3474 set/badspotter VE2STN
3477 will stop anything from VE2STN. If you want SSIDs as well then you must
3478 enter them specifically.
3481 unset/badspotter VE2STN
3484 will allow spots from him again.
3486 Use with extreme care. This command may well be superceded by FILTERing.
3492 <bf>set/beep</bf> Add beeps to terminal messages
3496 Add a beep to DX and other terminal messages.
3502 <bf>set/clx <node_call> [<node_call> ...]</bf> Make

3529 <sect1>set/dxgrid (0)
3533 <bf>set/dxgrid</bf>Allow grid squares on the end of DX messages
3537 Some logging programs do not like the additional information at
3538 the end of a DX spot. If this is the case, use the <em>unset/dxgrid</em>
3539 command to remove the grid squares.
3541 <sect1>set/dxnet (5)
3545 <bf>set/dxnet <node_call> [<node_call> ...]</bf> Make
3546 the node_call a DXNet type node
3550 Set the node_call as a DXNet type node
3556 <bf>set/echo</bf> Make the cluster echo your input
3560 If you are connected via a telnet session, different implimentations
3561 of telnet handle echo differently depending on whether you are
3562 connected via port 23 or some other port. You can use this command
3563 to change the setting appropriately.
3565 You can remove the echo with the <em>unset/echo</em> command
3567 The setting is stored in your user profile.
3569 YOU DO NOT NEED TO USE THIS COMMAND IF YOU ARE CONNECTED VIA AX25.
3575 <bf>set/here</bf> Set the here flag
3579 Let others on the cluster know you are here by only displaying your
3580 callsign. If you are away from your terminal you can use the <em>unset/here</em>
3581 command to let people know you are away. This simply puts brackets
3582 around your callsign to indicate you are not available.
3584 <sect1>set/homenode (0)
3588 <bf>set/homenode <node_call></bf> Set your home cluster
3592 Tell the cluster system where you normally connect to. Any Messages sent

3609 Set the hop count for a particular type of broadcast for a node.
3611 This command allows you to set up special hop counts for a node
3612 for currently: announce, spots, wwv and wcy broadcasts.
3616 set/hops gb7djk ann 10
3617 set/hops gb7mbc spots 20
3620 Set SHOW/HOPS for information on what is already set. This command
3621 creates a filter and works in conjunction with the filter system.
3623 <sect1>set/isolate (9)
3627 <bf>set/isolate <node call></bf> Isolate a node from the rest of the network
3631 Connect a node to your system in such a way that you are a full protocol
3632 member of its network and can see all spots on it, but nothing either leaks
3633 out from it nor goes back into from the rest of the nodes connected to you.
3635 You can potentially connect several nodes in this way.
3637 You can see which nodes are isolated with the show/isolate (1) command.
3639 You can remove the isolation with the command unset/isolate.
3641 <sect1>set/language (0)
3645 <bf>set/language <language></bf> Set the language you wish to use
3649 You can select the language that you want the cluster to use. Currently
3650 the languages available are <em>en</em> (English) and <em>nl</em> (Dutch).
3652 <sect1>set/location (0)
3656 <bf>set/location <lat and long></bf> Set your latitude and longitude
3660 You can set your latitude and longitude manually or alternatively use the
3661 <em>set/qra</em> command which will do the conversion for you.
3664 set/location 54 04 N 2 02 E
3668 <sect1>set/sys_location (9)
3672 <bf>set/sys_location <lat & long></bf> Set your cluster latitude and longitude
3676 In order to get accurate headings and such like you must tell the system
3677 what your latitude and longitude is. If you have not yet done a SET/QRA
3678 then this command will set your QRA locator for you. For example:-
3681 SET/LOCATION 52 22 N 0 57 E
3684 <sect1>set/logininfo (0)
3688 <bf>set/logininfo</bf> Show logins and logouts of nodes and users
3692 Show users and nodes when they log in and out of the local cluster. You
3693 can stop these messages by using the <em>unset/logininfo</em> command.
3696 <sect1>set/lockout (9)
3700 <bf>set/lockout <call></bf> Stop a callsign connecting to the cluster
3704 You can show who is locked out with the <em>show/lockout</em> command.
3705 To allow the user to connect again, use the <em>unset/lockout</em> command.
3711 <bf>set/name <your_name></bf> Set your name
3715 Tell the cluster what your name is, eg:-
3725 <bf>set/node <call> [<call> ...]</bf> Make the callsign an AK1A cluster
3729 Tell the system that the call(s) are to be treated as AK1A cluster and
3730 fed PC Protocol rather normal user commands.
3732 From version 1.41 you can also set the following types of cluster
3741 To see what your nodes are set to, use the <em>show/nodes</em> command.
3743 <sect1>set/obscount (9)
3747 <bf>set/obscount <count> <node call></bf> Set the 'pump-up'
3748 obsolescence counter
3752 From version 1.35 onwards neighbouring nodes are pinged at regular intervals (see
3753 SET/PINGINTERVAL), usually 300 seconds or 5 minutes. There is a 'pump-up'
3754 counter which is decremented on every outgoing ping and then reset to
3755 the 'obscount' value on every incoming ping. The default value of this
3758 What this means is that a neighbouring node will be pinged twice at
3759 (default) 300 second intervals and if no reply has been heard just before
3760 what would be the third attempt, that node is disconnected.
3762 If a ping is heard then the obscount is reset to the full value. Using
3763 default values, if a node has not responded to a ping within 15 minutes,
3770 <bf>set/page <n></bf> Set the number of lines per page
3774 Tell the system how many lines you wish on a page when the number of lines
3775 of output from a command is more than this. The default is 20. Setting it
3776 explicitly to 0 will disable paging.
3783 The setting is stored in your user profile.
3786 <sect1>set/password (9)
3790 <bf>set/password <callsign> <string></bf> Set a users password
3794 The password for a user can only be set by a full sysop. The string
3795 can contain any characters but any spaces are removed (you can type in
3796 spaces - but they won't appear in the password). You can see the
3797 result with STAT/USER. The password is the usual 30 character baycom
3800 <sect1>set/pinginterval (9)
3804 <bf>set/pinginterval <time> <node call></bf> Set the ping time
3805 to neighbouring nodes
3809 As from version 1.35 all neighbouring nodes are pinged at regular intervals
3810 in order to determine the rolling quality of the link and, in future, to
3811 affect routing decisions. The default interval is 300 secs or 5 minutes.
3813 You can use this command to set a different interval. Please don't.
3815 But if you do the value you enter is treated as minutes up 60 and seconds
3816 for numbers greater than that.
3818 This is used also to help determine when a link is down at the far end
3819 (as certain cluster software doesn't always notice), see SET/OBSCOUNT
3820 for more information.
3822 <sect1>set/privilege (9)
3826 <bf>set/privilege <n> <call> [<call> ...]</bf> Set the
3827 privilege level on a call
3831 Set the privilege level on a callsign. The privilege levels that pertain
3832 to commands are as default:-
3836 1 - allow remote nodes normal user RCMDs
3837 5 - various privileged commands (including shutdown, but not disc-
3838 connect), the normal level for another node.
3839 8 - more privileged commands (including disconnect)
3840 9 - local sysop privilege. DO NOT SET ANY REMOTE USER OR NODE TO THIS
3844 If you are a sysop and you come in as a normal user on a remote connection
3845 your privilege will automatically be set to 0.
3847 <sect1>set/spider (5)
3851 <bf>set/spider <node_call> [<node_call> ...]</bf> Make
3852 the node_call a DXSpider type node
3856 Set the node_call as a DXSpider type node
3858 <sect1>set/sys_qra (9)
3862 <bf>set/sys_qra <locator></bf> Set your cluster QRA locator
3869 <bf>set/qra <locator></bf> Set your QRA locator
3873 Tell the system what your QRA (or Maidenhead) locator is. If you have not
3874 done a SET/LOCATION then your latitude and longitude will be set roughly
3875 correctly (assuming your locator is correct ;-). For example:-
3885 <bf>set/qth <your QTH></bf> Set your QTH
3889 Tell the system where your are. For example:-
3892 set/qth East Dereham, Norfolk
3899 <bf>set/talk</bf> Allow talk messages to be seen at your console
3903 Allow talk messages to arrive at your console. You can switch off
3904 talks with the <em>unset/talk</em> command.

3970 for more information.
3972 <sect1>show/date (0)
3976 <bf>show/date [<prefix>|<callsign>]</bf> Show
3981 This is very nearly the same as SHOW/TIME, the only difference the format
3982 of the date string if no arguments are given.
3984 If no prefixes or callsigns are given then this command returns the local
3985 time and UTC as the computer has it right now. If you give some prefixes
3986 then it will show UTC and UTC + the local offset (not including DST) at
3987 the prefixes or callsigns that you specify.
3993 <bf>show/dx [options]</bf> interrogate the spot database
3997 If you just type SHOW/DX you will get the last so many spots
3998 (sysop configurable, but usually 10).
4000 In addition you can add any number of these options in very nearly
4001 any order to the basic SHOW/DX command, they are:-
4004 on <band> - eg 160m 20m 2m 23cm 6mm
4005 on <region> - eg hf vhf uhf shf (see SHOW/BANDS)
4007 <number> - the number of spots you want

4018 info <text> - any spots containing <text> in the info or remarks
4020 by <call> - any spots spotted by <call> (spotter <call>
4023 qsl - this automatically looks for any qsl info on the call
4024 held in the spot database.
4026 iota [<iota>] - If the iota island number is missing it will
4027 look for the string iota and anything which looks like
4028 an iota island number. If you specify then it will look
4031 qra [<locator>] - this will look for the specific locator if
4032 you specify one or else anything that looks like a locator.
4039 SH/DX on 20m info iota
4040 SH/DX 9a on vhf day 30
4047 <sect1>show/dxcc (0)
4051 <bf>show/dxcc <prefix></bf> Interrogate the spot database by country
4055 This command takes the <prefix> (which can be a full or partial
4056 callsign if desired), looks up which internal country number it is
4057 and then displays all the spots as per SH/DX for that country.
4059 The options for SHOW/DX also apply to this command.
4064 SH/DXCC W on 20m info iota
4067 <sect1>show/files (0)
4071 <bf>show/files [<filearea> [<string>]]</bf> List
4072 the contents of a filearea
4076 SHOW/FILES on its own will show you a list of the various fileareas
4077 available on the system. To see the contents of a particular file
4081 SH/FILES <filearea>
4084 where <filearea> is the name of the filearea you want to see the
4087 You can also use shell globbing characters like '*' and '?' in a
4088 string to see a selection of files in a filearea eg:-
4091 SH/FILES bulletins arld*
4094 See also TYPE - to see the contents of a file.
4096 <sect1>show/filter (0)
4100 <bf>show/filter</bf> Show the filters you have set
4104 Show the contents of all the filters that are set by you. This command
4105 displays all the filters set - for all the various categories.
4107 <sect1>show/filter (extended for sysops) (5)
4111 <bf>show/filter <callsign></bf> Show the filters set by <callsign>
4115 A sysop can look at any filters that have been set.
4117 <sect1>show/hops (8)
4121 <bf>show/hops <node_call> [ann|spots|wcy|wwv|]</bf> Show the hop
4126 This command shows the hop counts set up for a node. You can specify
4127 which category you want to see. If you leave the category out then
4128 all the categories will be listed.
4130 <sect1>show/isolate (1)
4134 <bf>show/isolate</bf> Show a list of isolated nodes
4138 Show which nodes are currently set to be isolated.
4140 <sect1>show/lockout (9)
4144 <bf>show/lockout</bf> Show a list of excluded callsigns
4148 Show a list of callsigns that have been excluded (locked out) of the
4149 cluster locally with the <em>set/lockout</em> command
4155 <bf>show/log [<callsign>]</bf> Show excerpts from the system log
4159 This command outputs a short section of the system log. On its own
4160 it will output a general logfile. With the optional callsign it will
4161 show output from the log associated with that callsign.
4163 <sect1>show/moon (0)
4167 <bf>show/moon [<prefix>|<callsign>]</bf> Show moon
4172 Show the Moon rise and set times for a (list of) prefixes or callsigns,
4173 together with the azimuth and elevation of the sun currently at those
4176 If you don't specify any prefixes or callsigns, it will show the times for
4177 your QTH (assuming you have set it with either SET/LOCATION or SET/QRA),
4178 together with the current azimuth and elevation.
4180 In addition, it will show the gain or loss dB relative to the nominal
4181 distance of 385,000Km due to the ellipsoidal nature of the orbit.
4183 If all else fails it will show the Moonrise and set times for the node
4184 that you are connected to.
4197 <bf>show/muf <prefix> [<hours>][long]</bf> Show
4198 the likely propagation to <prefix>
4202 This command allow you to estimate the likelihood of you contacting
4203 a station with the prefix you have specified. The output assumes a modest
4204 power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
4206 The result predicts the most likely operating frequencies and signal
4207 levels for high frequency (shortwave) radio propagation paths on
4208 specified days of the year and hours of the day. It is most useful for
4209 paths between 250 km and 6000 km, but can be used with reduced accuracy
4210 for paths shorter or longer than this.
4212 The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
4213 used to predict the MUF given the predicted flux, day of the year,
4214 hour of the day and geographic coordinates of the transmitter and
4215 receiver. This routine is reasonably accurate for the purposes here,
4216 with a claimed RMS error of 3.8 MHz, but much smaller and less complex
4217 than the programs used by major shortwave broadcasting organizations,
4218 such as the Voice of America.
4220 The command will display some header information detailing its
4221 assumptions, together with the locations, latitude and longitudes and
4222 bearings. It will then show UTC (UT), local time at the other end
4223 (LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
4224 (Zen) and the likely signal strengths. Then for each frequency for which
4225 the system thinks there is a likelihood of a circuit it prints a value.
4227 The value is currently a likely S meter reading based on the conventional
4228 6dB / S point scale. If the value has a '+' appended it means that it is
4229 1/2 an S point stronger. If the value is preceeded by an 'm' it means that
4230 there is likely to be much fading and by an 's' that the signal is likely
4233 By default SHOW/MUF will show the next two hours worth of data. You
4234 can specify anything up to 24 hours worth of data by appending the no of
4235 hours required after the prefix. For example:-
4244 RxSens: -123 dBM SFI: 159 R: 193 Month: 10 Day: 21
4245 Power : 20 dBW Distance: 6283 km Delay: 22.4 ms

4250 18 23 11.5 -35 mS0+ mS2 S3
4251 19 0 11.2 -41 mS0+ mS2 S3
4254 indicating that you will have weak, fading circuits on top band and
4255 80m but usable signals on 40m (about S3).
4263 will get you the above display, but with the next 24 hours worth of

4272 should be noted that the figures will probably not be very useful, nor
4273 terrible accurate, but it is included for completeness.

4279 <bf>show/node [<node_call> ...]</bf> Show the type and version
4284 Show the type and version (if connected) of the nodes specified on the
4285 command line. If no callsigns are specified then a sorted list of all
4286 the non-user callsigns known to the system will be displayed.
4288 <sect1>show/prefix (0)
4292 <bf>show/prefix <callsign></bf> Interrogate the prefix database
4296 This command takes the <callsign> (which can be a full or partial
4297 callsign or a prefix), looks up which internal country number
4298 it is and then displays all the relevant prefixes for that country
4299 together with the internal country no, the CQ and ITU regions.
4304 <sect1>show/program (5)
4308 <bf>show/program</bf> Show the locations of all the included program modules
4312 Show the name and location where every program module was load from. This
4313 is useful for checking where you think you have loaded a .pm file from.
4319 <bf>show/qra <locator> [<locator>]</bf> Show the distance
4320 between locators<newline>
4321 <bf>show/qra <lat> <long></bf> Convert latitude and longitude to
4326 This is a multipurpose command that allows you either to calculate the
4327 distance and bearing between two locators or (if only one locator is
4328 given on the command line) the distance and beraing from your station
4329 to the locator. For example:-
4336 The first example will show the distance and bearing to the locator from
4337 yourself, the second example will calculate the distance and bearing from
4338 the first locator to the second. You can use 4 or 6 character locators.
4340 It is also possible to convert a latitude and longitude to a locator by
4341 using this command with a latitude and longitude as an argument, for

4387 If you use this command without a satellite name it will display a list
4388 of all the satellites known currently to the system.
4390 If you give a name then you can obtain tracking data of all the passes
4391 that start and finish 5 degrees below the horizon. As default it will
4392 give information for the next three hours for every five minute period.

4443 time and UTC as the computer has it right now. If you give some prefixes
4444 then it will show UTC and UTC + the local offset (not including DST) at
4445 the prefixes or callsigns that you specify.
4451 <bf>show/wcy</bf> Show the last 10 WCY broadcasts<newline>
4452 <bf>show/wcy <n></bf> Show the last <n> WCY broadcasts
4456 Display the most recent WCY information that has been received by the system
4462 <bf>show/wwv</bf> Show the last 10 WWV broadcasts<newline>
4463 <bf>show/wwv <n></bf> Show the last <n> WWV broadcasts
4467 Display the most recent WWV information that has been received by the system
4474 <bf>shutdown</bf> Shutdown the cluster
4478 Shutdown the cluster and disconnect all the users. If you have Spider
4479 set to respawn in /etc/inittab it will of course restart.
4485 <bf>spoof <callsign> <command></bf> Run commands as another user
4489 This is a very simple yet powerful command for the sysop. It allows you to
4490 issue commands as if you were a different user. This is very useful for the
4491 kind of things that users seem to always get wrong.. like home_node for
4498 <bf>stat/db <dbname></bf> Show the status of a database
4502 Show the internal status of a database descriptor.
4504 Depending on your privilege level you will see more or less information.
4505 This command is unlikely to be of much use to anyone other than a sysop.
4507 <sect1>stat/channel (5)
4511 <bf>stat/channel <callsign></bf> Show the status of a channel on the cluster
4515 Show the internal status of the channel object either for the channel that
4516 you are on or else for the callsign that you asked for.
4518 Only the fields that are defined (in perl term) will be displayed.
4524 <bf>stat/msg <msgno></bf> Show the status of a message
4528 This command shows the internal status of a message and includes information
4529 such as to whom it has been forwarded, its size, origin etc etc.
4531 <sect1>stat/user (5)
4535 <bf>stat/user <callsign></bf> Show the full status of a user
4539 Shows the full contents of a user record including all the secret flags
4542 Only the fields that are defined (in perl term) will be displayed.
4548 <bf>sysop</bf> Regain your privileges if you login remotely
4552 The system automatically reduces your privilege level to that of a
4553 normal user if you login in remotely. This command allows you to
4554 regain your normal privilege level. It uses the normal system: five
4555 numbers are returned that are indexes into the character array that is
4556 your assigned password (see SET/PASSWORD). The indexes start from
4559 You are expected to return a string which contains the characters
4560 required in the correct order. You may intersperse those characters
4561 with others to obscure your reply for any watchers. For example (and
4562 these values are for explanation :-):
4565 password = 012345678901234567890123456789
4573 aa2bbbb0ccc5ddd7xxx3n
4578 They will all match. If there is no password you will still be offered
4579 numbers but nothing will happen when you input a string. Any match is
4586 <bf>talk <callsign></bf> Enter talk mode with <callsign><newline>
4587 <bf>talk <callsign> <text></bf> Send a text message to <callsign><newline>
4588 <bf>talk <callsign> > <node_call> [<text>]</bf>
4589 Send a text message to <callsign> via <node_call>
4593 Send a short message to any other station that is visible on the cluster
4594 system. You can send it to anyone you can see with a SHOW/CONFIGURATION
4595 command, they don't have to be connected locally.
4597 The second form of TALK is used when other cluster nodes are connected
4598 with restricted information. This usually means that they don't send
4599 the user information usually associated with logging on and off the cluster.
4601 If you know that G3JNB is likely to be present on GB7TLH, but you can only
4602 see GB7TLH in the SH/C list but with no users, then you would use the
4603 second form of the talk message.
4605 If you want to have a ragchew with someone you can leave the text message
4606 out and the system will go into 'Talk' mode. What this means is that a
4607 short message is sent to the recipient telling them that you are in a 'Talking'
4608 frame of mind and then you just type - everything you send will go to the
4609 station that you asked for.
4611 All the usual announcements, spots and so on will still come out on your
4614 If you want to do something (such as send a spot) you precede the normal
4615 command with a '/' character, eg:-
4618 /DX 14001 G1TLH What's a B class licensee doing on 20m CW?
4622 To leave talk mode type:
4632 <bf>type <filearea>/<name></bf> Look at a file in one of the fileareas
4636 Type out the contents of a file in a filearea. So, for example, in
4637 filearea 'bulletins' you want to look at file 'arld051' you would
4641 TYPE bulletins/arld051
4644 See also SHOW/FILES to see what fileareas are available and a
4651 <bf>who</bf> Show who is physically connected locally
4655 This is a quick listing that shows which callsigns are connected and
4656 what sort of connection they have
4662 <bf>wx <text></bf> Send a weather message to local users<newline>
4663 <bf>wx full <text> </bf> Send a weather message to all cluster users
4667 Weather messages can sometimes be useful if you are experiencing an extreme
4668 that may indicate enhanced conditions
4670 <sect1>wx (enhanced for sysops) (5)
4674 <bf>wx sysop <text></bf> Send a weather message to other clusters only
4678 Send a weather message only to other cluster nodes and not to general users.
