<sect1>Introduction
<P>
-This section describes the installation of DX Spider v1.35 on a <htmlurl url="http://www.redhat.com" name="RedHat"> Linux Distribution. I do not intend to try and cover the installation of Linux or the setup of the AX25 utilities. If you need help on this then read Iains original HOWTO on the <htmlurl url="http://www.dxcluster.org" name="DXSpider"> website.
-
-<P>
-I am assuming a general knowledge of Linux and its commands. You should know how to use <em>tar</em> and how to edit files using your favourite editor.
-
-<P>
-The crucial ingredient for all of this is <htmlurl url="http://www.perl.org" name="Perl 5.004">.Now I know Perl 5.005 is out and this will almost certainly work with it, but <htmlurl url="http://www.redhat.com" name="RedHat 5.1"> comes with 5.004. <em>Be Warned</em>, earlier versions of <htmlurl url="http://www.redhat.com" name="RedHat"> <bf>do not</bf> come with 5.004 as standard, you need to <htmlurl url="ftp://upgrade.redhat.com" name="upgrade">
-
-<P>In addition to the standard Red Hat distribution you will require the following <htmlurl url="http://www.cpan.org/CPAN.html" name="CPAN"> modules: -
-
-<P>
-<itemize>
-
-<item> MD5-1.7.tar.gz
-<item> Data-Dumper-2.10.tar.gz
-<item> FreezeThaw-0.3.tar.gz
-<item> MLDBM-2.00.tar.gz
-<item> TimeDate-1.8.tar.gz
-<item> IO-1.20.tar.gz
-<item> Net-Telnet-3.02.tar.gz
-<item> Curses-1.05.tar.gz
-
-</itemize>
-
-<P>
-
-<em>Do</em> get the latest versions of these packages and install them but use the above list as the earliest versions usable.
-
-<sect1>Preparation
-
-<P>
-I will assume that you have already downloaded the latest tarball of the DXSpider software and are ready to install it. I am assuming version 1.35 for this section but of course you would use the latest version.
-
-<P>
-Login as root and create a user to run the cluster under. <bf><it>UNDER NO CIRCUMSTANCES USE ROOT AS THIS USER!</it></bf>. I am going to use the name <em>sysop</em>. You can call it anything you wish. Depending on your security requirements you may wish to use an existing user, however this is your own choice.
+From DXSpider version 1.48, major changes were introduced to the way
+node connections are treated. This is part of an ongoing process to
+remove problems with loops and to enable talk and other functions to
+propagate across the whole of the worldwide cluster network. In fact,
+in a Spider network, it would be useful, perhaps even necessary to
+have loops. This would give real resilience to the network, meaning
+that if a link dropped, the information flow would simply come in and
+go out via a different route. Of course, we do not have a complete
+network of Spider nodes, there are other programs out there. Some of
+these do not have any protection from loops. Certainly AK1A does not
+handle loops well at all. It is therefore necessary to have some form
+of protection for these nodes.
+
+<P>
+In fact DXSpider has had a simple system for some time which is called
+<it>isolation</it>. This is similar to what, in other systems such as
+<bf>clx</bf>, is called <it>passive mode</it>. A more detailed explanation
+of <it>isolation</it> is given further below. This system is still available
+and, for simple networks, is probably all that you need.
+
+<P>
+The new functionality introduced in version 1.48 is filtering the node
+and user protocol frames on a "per interface" basis. We call this
+<it>route filtering</it>. This is used <bf>instead of</bf>
+<it>isolation</it>.
+
+<p>
+What this really means is that you can control more or less completely
+which PC protocol frames, to do with user and node management, pass to
+each of your partner nodes. You can also limit what comes into your
+node from your partners. You can even control the settings that your
+partner node has for the routing information that it sends to you
+(using the <it>rcmd</it> command).
+
+<sect1>Route Filters
+
+<p>
+Initially when route filters were being tested we generated a
+"default" filter. Unfortunately it quickly became apparent that this
+might suit the UK cluster network but didn't really fit anybody else.
+However using a default filter is an appropriate thing to do. How, is
+explained further on.
+
+<p>
+The first thing that you must do is determine whether you need to do route filtering <bf>at all</bf>. If you are a "normal" node with two or three partners
+and you arranged in an "official" non-looping tree type network, then <bf>you do
+not need to do route filtering</bf> and you will feel a lot better for not
+getting involved. If you are successfully using <it>isolation</it> then you
+also probably don't need to use route filtering.
+
+<p>
+You will only require this functionality if you are
+"well-connected". What that means is that you are connected to several
+different parts of (say) the EU cluster and, at the same time, also
+connected to two or three places in the US which, in turn are
+connected back to the EU. This is called a "loop" and if you are
+seriously looped then you need filtering.
+
+<P>
+I should at this stage give a little bit of background on filters. All
+the filters in Spider work in basically the same way. You can either
+accept or reject various options in order to create the filter rules
+you wish to achieve. Some filters are user settable, others can only
+be altered by the sysop. Route filtering can only be done by the sysop.
+
+<P>
+Anyway, without further discouragement, let me start the process
+of explanation.
+
+<sect1>The node_default filter
+
+<P>
+All normal systems should have a default routing filter and it should
+usually be set to send only the normal, unlooped, view of your
+"national" network. Here in the UK that means nodes from the UK and
+Eire, in EU it is more complex as the networks there grew up in a more
+intertwined way.
+
+<p>
+The generic commands are:-
-<P>
<tscreen><verb>
-# adduser -m sysop
-</verb></tscreen>
+reject/route node_default <filter_option>
-<P>
-Now set a password for the user ...
+or
-<tscreen><verb>
-# passwd sysop
-# New UNIX password:
-# Retype new UNIX password:
-passwd: all authentication tokens updated successfully
+accept/route node_default <filter_option>
</verb></tscreen>
-<sect1>Installing the software
-
-<P>
-Now to unpack the DX Spider distribution, set symbolic links and group permissions. Copy the tarball to /home/sysop and do the following.
+where filter_option is one of the following ...
<tscreen><verb>
-# cd ~sysop
-# tar xvfz spider-1.35.tar.gz
-# ln -s ~sysop/spider /spider
-# groupadd -g 251 spider (or another number)
+call <prefixes>
+call_dxcc <numbers>
+call_itu <numbers>
+call_zone <numbers>
+channel <prefixes>
+channel_dxcc <numbers>
+channel_itu <numbers>
+channel_zone <numbers>
</verb></tscreen>
-If you do not have the command <em>groupadd</em> available to you simply add a line in /etc/group by hand.
+Please be careful if you alter this setting, it will affect
+<bf><it>ALL</it></bf> your links!
+
+<p>
+For the default routing filter then you have two real choices: either
+a "national" view or the "safe" option of only your own
+callsign. Examples of each (for my node: GB7DJK) are:-
<tscreen><verb>
-# vi /etc/group (or your favorite editor)
+acc/route node_default call_dxcc 61,38
+acc/route node_default call gb7djk
</verb></tscreen>
-You also need to add some others to the group, including your own callsign (this will be used as an alias) and root. The finished line in /etc/group should look something like this
+GB7DJK uses the first of these. The DXCC countries can be obtained from the
+<it>show/prefix</it> command.
-<tt>
-spider:x:251:sysop,g0vgs,root
-</tt>
+<p>
+The example filters shown control <it>output</it> <bf>TO</bf> all your
+partner nodes unless they have a specific filter applied to them (see
+next section).
-<P>
-The next step is to set the permissions on the Spider directory tree and files ....
+<p>
+It is also possible to control the <it>incoming</it> routing
+information that you are prepared to accept <bf>FROM</bf> your partner
+nodes. The reason this is necessary is to make sure that stuff like
+mail, pings and similar commands a) go down the correct links and b)
+don't loop around excessively. Again using GB7DJK as an example a typical
+default input filter would be something like:
<tscreen><verb>
-# chown -R sysop.spider spider
-# find . -type d -exec chmod 2775 {} \;
-# find . -type f -exec chmod 775 {} \;
+rej/route node_default input call_dxcc 61,38 and not channel_dxcc 61,38
</verb></tscreen>
-<P>
-This last step allows various users of the group <em>spider</em> to have write access to all the directories. This is not really needed just yet but will be useful when web interfaces start to appear.
+What this does is accept node and user information for our national
+network from nodes that are in our national network, but rejects such
+information from anyone else. Although it doesn't explicitly say so,
+by implication, any other node information (not from the UK and Eire)
+is accepted.
-<P>
-Finally, you need to fix the permissions on the ax25_call and netrom_call programs. Check where they are with the <em>locate</em> command and alter the permissions with the <em>chmod</em> command like this ..
+<p>
+As I imagine it will take a little while to get one's head around all of this you
+can study the effect of any rules that you try by watching the debug output
+after having done:-
<tscreen><verb>
-# chown root ax25_call netrom_call
-# chmod 4775 ax25_call netrom_call
+set/debug filter
</verb></tscreen>
-<sect1>Setting callsigns etc
-
-<P>
-Now login to your machine as the user you created earlier. In my case that user is called <em>sysop</em>. Once logged in, issue the following commands ....
+After you have got tired of that, to put it back the way it was:-
<tscreen><verb>
-$ cd /spider
-$ mkdir local
-$ mkdir local_cmd
-$ cp perl/DXVars.pm.issue local/DXVars.pm
-$ cd local
-$ vi DXVars.pm (or your favourite editor)
+unset/debug filter
</verb></tscreen>
-<P>
-Using the distributed DXVars.pm as a a template, set your cluster callsign, sysop callsign and other user info to suit your own environment. Note that this a perl file which will be parsed and executed as part of the cluster. If you get it wrong then perl will complain when you start the cluster process. It is important only to alter the text of any section. Some of the lines look a little odd. Take this line for example ....
-
-<tt>
-$myemail = "ianmaude\@btinternet.com";
-</tt>
-
-<P>
-There appears to be an extra slash in there. However this has to be there for the file to work so leave it in.
-
-<P><bf>PLEASE USE CAPITAL LETTERS FOR CALLSIGNS</bf>
-
-<P>
-DON'T alter the DXVars.pm (or any other file) in /spider/perl, they are overwritten with every release. Any files or commands you place in /spider/local or /spider/local_cmd will automagically be used in preference to the ones in /spider/perl EVEN while the cluster is running!
-
-<P>
-Save the new file and change directory to ../perl ....
-
-<tscreen><verb>
-$ cd ../perl
-</verb></tscreen>
+<sect1>General route filtering
<P>
-Now type the following command which creates the basic user file with you as the sysop.
+Exactly the same rules apply for general route filtering. You would
+use either an accept filter or a reject filter like this ...
<tscreen><verb>
-$ create_sysop.pl
-</verb></tscreen>
-
-<sect1>Starting up for the first time
+reject/route <node_call> <filter_option>
-<P>
-We can now bring spider up for the first time and see if all is well or not! It should look something like this ...
+or
-<tscreen><verb>
-$ cluster.pl
-DXSpider DX Cluster Version 1.35

-loading prefixes ...
-loading band data ...
-loading user file system ...
-starting listener ...
-reading existing message headers
-reading cron jobs
-orft we jolly well go ...
+accept/route <node_call> <filter_option>
</verb></tscreen>
<P>
-If all is well then login on another term or console as <em>sysop</em> and cd to /spider/perl. Now issue the following command ...
+Here are some examples of route filters ...
<tscreen><verb>
-$ client.pl
+rej/route gb7djk call_dxcc 61,38 (everything except UK+EIRE nodes)
+rej/route all (equiv to [very] restricted mode)
+acc/route gb7djk call_dxcc 61,38 (send only UK+EIRE nodes)
+acc/route gb7djk call gb7djk (equiv to SET/ISOLATE)
</verb></tscreen>
-<P>
-This should log you into the cluster as the sysop under the alias callsign we set earlier. In this case the callsign is G0VGS. The cluster callsign is set in the DXVars.pm file in /spider/local. In this case we will assume that this was set as GB7MBC. You should therefore see this when you login ....
-
+In practice you will either be opening the default filter out for a
+partner by defining a specific filter for that callsign:-
+
<tscreen><verb>
-G0VGS de GB7MBC 19-Nov-1999 2150Z >
+acc/route gb7baa all
+acc/route gb7baa input all
</verb></tscreen>
-If you do, congratulations! If not, look over the instructions again, you have probably missed something out. You can shut spider down again with the command ....
+or restricting it quite a lot, in fact making it very nearly like an <it>isolated</it> node, like this:-
<tscreen><verb>
-shutdown
+acc/route pi4ehv-8 call gb7djk
+rej/route pi4ehv-8 input call_dxcc 61,38
</verb></tscreen>
-<P>
-and both the cluster and the client should return to Linux prompts.
-
-<sect>The Client program
+This last example takes everything except UK and Eire from PI4EHV-8
+but only sends him my local configuration (just a PC19 for GB7DJK and
+PC16s for my local users).
-<P>
-In earlier versions of Spider, all the processes were Perl scripts. This was fine but with a lot of users your computer memory would soon be used up. To combat this a new client was written in "C". This client only works for <em>incoming</em> connects at the moment. Before you can use it though it has to be "made". CD to /spider/src and type <em>make</em>. You should see the output on your screen and hopefully now have a small C program called <em>client</em>. Leave it in this directory.
+<p>
+It is possible to do <bf>much</bf> more complex rules, there are up to 10
+accept/reject pairs per callsign per filter. For more information see the
+next section.
-<sect>Configuration
-<sect1>Allowing ax25 connects from users
+<sect1>General filter rules
<P>
-As stated previously, the aim of this document is not to tell you how to configure Linux or the ax25 utilities. However, you do need to add a line in your ax25d.conf to allow connections to DXSpider for your users. For each interface that you wish to allow connections on, use the following format ...
-
-<tscreen><verb>
-default * * * * * * - sysop /spider/src/client client %u ax25
-</verb></tscreen>
-
-<sect1>Allowing telnet connects from users
+Upto v1.44 it was not possible for the user to set their own filters. From
+v1.45 though that has all changed. It is now possible to set filters for just
+about anything you wish. If you have just updated from an older version of
+DXSpider you will need to update your new filters. You do not need to do
+anything with your old filters, they will be renamed as you update.
<P>
-Allowing telnet connections is quite simple. Firstly you need to add a line in /etc/services to allow connections to a port number, like this ....
-
-<tscreen><verb>
-spdlogin 8000/tcp # spider anonymous login port
-</verb></tscreen>
-
-Then add a line in /etc/inetd.conf like this ....
-
-<tscreen><verb>
-spdlogin stream tcp nowait root /usr/sbin/tcpd /spider/src/client login telnet
-</verb></tscreen>
+There are 3 basic commands involved in setting and manipulating filters. These
+are <em>accept</em>, <em>reject</em> and <em>clear</em>. First we will look
+generally at filtering. There are a number of things you can filter in the
+DXSpider system. They all use the same general mechanism.
<P>
-This needs to be added above the standard services such as ftp, telnet etc. Once this is done, you need to restart inetd like this ....
+In general terms you can create a "reject" or an "accept" filter which can have
+up to 10 lines in it. You do this using, for example ...
-<tscreen><verb>
-killall -HUP inetd
+<tscreen><verb>
+accept/spots .....
+reject/spots .....
</verb></tscreen>
+where ..... are the specific commands for that type of filter. There are filters
+for spots, wwv, announce, wcy and (for sysops) connects. See each different
+accept or reject command reference for more details.
-<P>Now login as <em>sysop</em> and cd spider/perl. You can test that spider is accepting telnet logins by issuing the following command ....
+There is also a command to clear out one or more lines in a filter. They are ...
<tscreen><verb>
-client.pl login telnet
+clear/spots 1
+clear/spots all
</verb></tscreen>
-You should get a login prompt and on issuing a callsign, you will be given access to the cluster. Note, you will not get a password login. There seems no good reason for a password prompt to be given so it is not asked for.
+There is clear/xxxx command for each type of filter.
<P>
-Assuming all is well, then try a telnet from your linux console ....
+and you can check that your filters have worked by the command ...
-<tscreen><verb>
-telnet localhost 8000
+<tscreen><verb>
+show/filter
</verb></tscreen>
<P>
-You should now get the login prompt and be able to login as before.
+For now we are going to use spots for the examples, but you can apply the same
+principles to all types of filter.
-<sect1>Setting up node connects
+<sect1>Types of filter
<P>
-In order to allow cluster node connections, spider needs to know that the connecting callsign is a cluster node. This is the case whether the connect is incoming or outgoing.
-In spider this is a simple task and can be done in runtime.
+There are two main types of filter, <em>accept</em> or <em>reject</em>. You
+can use either to achieve the result you want dependent on your own preference
+and which is more simple to do. It is pointless writing 8 lines of reject
+filters when 1 accept filter would do the same thing! Each filter has 10
+lines (of any length) which are tried in order. If a line matches then the
+action you have specified is taken (ie reject means ignore it and accept
+means take it)
<P>
-Start up the cluster as you did before and login as the sysop with client.pl.
-The cluster node I am wanting to make a connection to is GB7BAA but you would obviously use whatever callsign you required.
-At the prompt type ...
+If you specify reject filters, then any lines that arrive that match the filter
+will be dumped but all else will be accepted. If you use an accept filter,
+then ONLY the lines in the filter will be accepted and all else will be dumped.
+For example if you have a single line <em>accept</em> filter ...
<tscreen><verb>
-set/node gb7baa
+accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
</verb></tscreen>
-<P>
-The case does not matter as long as you have a version of DXSpider later than 1.33. Earlier versions required the callsign to be in upper case.
+then you will <em>ONLY</em> get VHF spots <em>from</em> or <em>to</em> CQ zones
+14, 15 and 16.
<P>
-That is now set, it is as simple as that. To prove it, login on yet another console as sysop and issue the command ...
+If you set a reject filter like this ...
<tscreen><verb>
-client.pl gb7baa (using the callsign you set as a node)
+reject/spots on hf/cw
</verb></tscreen>
-<P>
-You should get an initialisation string from DXSpider like this ...
+Then you will get everything <em>EXCEPT</em> HF CW spots. You could make this
+single filter even more flexible. For example, if you are interested in IOTA
+and will work it even on CW even though normally you are not interested in
+CW, then you could say ...
<tscreen><verb>
-client.pl gb7baa
-PC38^GB7MBC^~
+reject/spots on hf/cw and not info iota
</verb></tscreen>
-If the callsign you just set up as a cluster node is for an incoming connect, this is all that needs to be done. If the connection is to be outgoing then a connection script needs to be written.
-
-<sect2>Connection scripts
-
-<P>
-Because DXSpider operates under Linux, connections can be made using just about any protocol; AX25, NETRom, tcp/ip, ROSE etc are all possible examples. Connect scripts live in the /spider/connect directory and are simple ascii files. Writing a script for connections is therefore relatively simple.
-
-<P>
-The connect scripts consist of lines which start with the following keywords or symbols:-
-
-
-<verb>
-
-# All lines starting with a # are ignored, as are completely blank lines.
-
-timeout timeout followed by a number is the number of seconds to wait for a
- command to complete. If there is no timeout specified in the script
- then the default is 60 seconds.
-
-abort abort is a regular expression containing one or more strings to look
- for to abort a connection. This is a perl regular expression and is
- executed ignoring case.
-
-connect connect followed by ax25 or telnet and some type dependent
- information. In the case of a telnet connection, there can be up to
- two parameters.
- The first is the ip address or hostname of the computer you wish to
- connect to and the second is the port number you want to use (this
- can be left out if it is a normal telnet session).
- In the case of an ax25 session then this would normally be a call to
- ax25_call or netrom_call as in the example above. It is your
- responsibility to get your node and other ax25 parameters to work
- before going down this route!
-
-' ' is the delimiting character for a word or phrase of an expect/send
- line in a chat type script. The words/phrases normally come in pairs,
- either can be empty. Each line reads input from the connection until
- it sees the string (or perl regular expression) contained in the
- left hand string. If the left hand string is empty then it doesn't
- read or wait for anything. The comparison is done ignoring case.
- When the left hand string has found what it is looking for (if it is)
- then the right hand string is sent to the connection.
- This process is repeated for every line of chat script.
-
-client client starts the connection, put the arguments you would want here
- if you were starting the client program manually. You only need this
- if the script has a different name to the callsign you are trying to
- connect to (i.e. you have a script called other which actually
- connects to GB7DJK-1 [instead of a script called gb7djk-1]).
-</verb>
-
-
-There are many possible ways to configure the script but here are two examples, one for a NETRom/AX25 connect and one for tcp/ip.
+But in that case you might only be interested in iota and say:-
<tscreen><verb>
- timeout 60
- abort (Busy|Sorry|Fail)
- # don't forget to chmod 4775 netrom_call!
- connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh
- 'Connect' ''
- 'Connect' 'c np7'
- 'Connect' 'c gb7dxm'
- # you can leave this out if you call the script 'gb7dxm'
- client gb7dxm ax25
+accept/spots not on hf/cw or info iota
</verb></tscreen>
+which achieves exactly the same thing. You should choose one or the other
+until you are comfortable with the way it works. You can mix them if you
+wish (actually you can have an accept AND a reject on the same line) but
+don't attempt this until you are sure you know what you are doing!
+
<P>
+You can arrange your filter lines into logical units, either for your own
+understanding or simply convenience. Here is an example ...
<tscreen><verb>
- timeout 15
- connect telnet dirkl.tobit.co.uk
- 'login' 'gb7djk'
- 'word' 'gb7djk'
- # tell GB7DJK-1 that it is connected to GB7DJK
- # you can leave this out if you call this script 'gb7djk'
- client gb7djk telnet
+reject/spots 1 on hf/cw
+reject/spots 2 on 50000/1400000 not (by_zone 14,15,16 or call_zone 14,15,16)
</verb></tscreen>
-<P>
-Both these examples assume that everything is set up properly at the other end. You will find other examples in the /spider/examples directory.
+What this does is to ignore all HF CW spots and also rejects any spots on VHF
+which don't either originate or spot someone in Europe.
-<sect2>Starting the connection
+<P>
+This is an example where you would use a line number (1 and 2 in this case), if
+you leave the digit out, the system assumes '1'. Digits '0'-'9' are available.
+This make it easier to see just what filters you have set. It also makes it
+more simple to remove individual filters, during a contest for example.
<P>
-You start the connection, from within a sysop enabled cluster login, by typing in the word <em>connect</em> followed by a script name like this ....
+You will notice in the above example that the second line has brackets. Look
+at the line logically. You can see there are 2 separate sections to it. We
+are saying reject spots that are VHF or above <em>APART</em> from those in
+zones 14, 15 and 16 (either spotted there or originated there). If you did
+not have the brackets to separate the 2 sections, then Spider would read it
+logically from the front and see a different expression entirely ...
<tscreen><verb>

+As mentioned earlier, setting several filters can be more flexible than
+simply setting one complex one. Doing it in this way means that if you want
+to alter your filter you can just redefine or remove one or more lines of it or
+one line. For example ...
+<tscreen><verb>
+reject/spots 1 on hf/ssb
</verb></tscreen>
-<P>
-With later versions of Spider there is a set/login command for users. This tells them when a user or node logs in or out. If you do not add a line to your scripts after the final line (or before the client line which should always be last if needed) then the login/logout information will be sent to users <it>before</it> the login actually completes. This means if a node is unreachable, it will continue sending logins and logouts to users even though it is not actually connecting. To avoid this use the following line ...
+would redefine our earlier example, or
<tscreen><verb>
-'connect' ''
+clear/spots 1
</verb></tscreen>
-<P>
-In a script, this might look like ...
+To remove all the filter lines in the spot filter ...
<tscreen><verb>
-timeout 35
-abort (Busy|Sorry|Fail)
-connect telnet mary 3000
-'ogin:' 'gb7mbc'
-'>' 'telnet 44.131.93.96 7305'
-'connect' ''
+clear/spots all
</verb></tscreen>
-<sect1>Automating things
+<sect1>Filter options
<P>
-Ok, you should now have DXSpider running nicely and allowing connects by cluster nodes or users. However, it has to be shutdown and restarted manually and if connection scripts fail they have to be started again manually too, not much use if you are not at the console!
-So, in this section we will automate both. Firstly starting the cluster.
+You can filter in several different ways. The options are listed in the
+various helpfiles for accept, reject and filter.
-<sect2>Autostarting the cluster
-
-<P>
-This is not only a way to start the cluster automatically, it also works as a watchdog, checking the sanity of DXSpider and respawning it should it crash for any reason.
-Before doing the following, shutdown the cluster as you did earlier.
+<sect1>Default filters
<P>
-Login as root and bring up the /etc/inittab file in your favourite editor. Add the following lines to the file near the end ...
+Sometimes all that is needed is a general rule for node connects. This can
+be done with a node_default filter. This rule will always be followed, even
+if the link is isolated, unless another filter is set specifically. Default
+rules can be set for nodes and users. They can be set for spots, announces,
+WWV and WCY. They can also be used for hops. An example might look like
+this ...
<tscreen><verb>
-##Start DXSpider on bootup and respawn it should it crash
-DX:3:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
+accept/spot node_default by_zone 14,15,16,20,33
+set/hops node_default spot 50
</verb></tscreen>
-<P>
-This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart it should it crash for any reason.
+This filter is for spots only, you could set others for announce, WWV and WCY.
+This filter would work for ALL nodes unless a specific filter is written to
+override it for a particular node. You can also set a user_default should
+you require. It is important to note that default filters should be
+considered to be "connected". By this I mean that should you override the
+default filter for spots, you need to add a rule for the hops for spots also.
-<P>
-As root type the command <em>telinit q</em>. DXSpider should start up immediately. You will see the output on tty7 and if you login as <em>sysop</em> you should find everything running nicely.
+<sect1>Advanced filtering
<P>
-So far so good, now to automate script connections...
-
-<sect2>The crontab file
+Once you are happy with the results you get, you may like to experiment.
<P>
-Login as <em>sysop</em> and create a file in /spider/local_cmd called crontab. Edit it with your favourite editor and add a line like this (I have included a comment)
+The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU
+can be written with a mixed filter, for example ...
<tscreen><verb>
-# check every 10 minutes to see if gb7xxx is connected and if not
-# start a connect job going
-
-0,10,20,30,40,50 * * * * start_connect('gb7xxx') if !connected('gb7xxx')
+rej/spot on hf/cw
+acc/spot on 0/30000
+acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
</verb></tscreen>
-<P>
-The callsign involved will be the callsign of the cluster node you are going to connect to. This will now check every 10 minutes to see if gb7xxx is connected, if it is then nothing will be done. If it is not, then a connect attempt will be started.
-
-<P>
-There are probably lots of other things you could use this crontab file for. If you want to know more about it, look at the <htmlurl url="http://www.dxcluster.org/cron.html" name="DXSpider"> website at the cron page where it is explained more fully.
-
-<sect>Hop control
+Note that the first filter has not been specified with a number. This will
+automatically be assumed to be number 1. In this case, we have said <em>reject all
+HF spots in the CW section of the bands but accept all others at HF. Also
+accept anything in VHF and above spotted in or by operators in the zones
+14, 15 and 16</em>. Each filter slot actually has a 'reject' slot and
+an 'accept' slot. The reject slot is executed BEFORE the accept slot.
<P>
-Starting with version 1.13 there is simple hop control available on a per
-node basis. Also it is possible to isolate a network completely so that you
-get all the benefits of being on that network, but can't pass on information
-from it to any other networks you may be connected to (or vice versa).
+It was mentioned earlier that after a reject test that doesn't match, the default
+for following tests is 'accept', the reverse is true for 'accept'. In the example
+what happens is that the reject is executed first, any non hf/cw spot is passed
+to the accept line, which lets through everything else on HF. The next filter line
+lets through just VHF/UHF spots from EU.
<sect1>Basic hop control
<P>
-In /spider/data you will find a file called hop_table.pl. This is the file that controls your hop count settings. It has a set of default hops on the various PC frames and also a set for each node you want to alter the hops for. You may be happy with the default settings of course, but this powerful tool can help to protect and improve the network. The file will look something like this ...

-Each set of hops is contained within a pair of curly braces and contains a series of PC frame types. PC11 for example is a DX spot. The figures here are not exhaustive but should give you a good idea of how the file works.

+
+<sect1>Hop Control on Specific Nodes

+<p>You can set a callsign specific hop count for any of the standard filter
+options so:-
+
+<tscreen><verb>
+set/hops gb7djk spot 4
+set/hops node_default route 10
+set/hops gb7baa wcy 5
+</verb></tscreen>
+

+
+<p>
+The <em>set/hops</em> command overrides any hops that you have set otherwise.
+
+<p>
+You can set what hops have been set using the <em>show/hops</em> command.
<sect1>Isolating networks
<P>
The effect of this is to partition an isolated network completely from another
-nodes connected to your node. Your node will appear on and otherwise behave
+node connected to your node. Your node will appear on and otherwise behave
normally on every network to which you are connected, but data from an isolated
network will not cross onto any other network or vice versa. However all the
spot, announce and WWV traffic and personal messages will still be handled
node and it will be routed across.
<P>
-The only limitation currently is that non-private messages cannot be passed down
-isolated links regardless of whether they are generated locally. This will change
-when the bulletin routing facility is added.
-
-<P>
-If you use isolate on a node connection you will continue to receive all information from the isolated partner, however you will not pass any information back to the isolated node. There are times when you would like to forward only spots across a link (maybe during a contest for example). To do this, isolate the node in the normal way and put in a filter in the /spider/filter/spots directory to override the isolate. This filter can be very simple and consists of just one line ....
-
-<tscreen><verb>
-$in = [
- [ 1, 0, 'd', 0, 3] # The last figure (3) is the hop count
-];
-</verb></tscreen>
-
-<P>
-There is a lot more on filtering in the next section.
-
-<sect>Filtering
-
-<P>
-Filters can be set for spots, announcements and WWV. You will find the directories for these under /spider/filter. You will find some examples in the directories with the suffix <em>.issue</em>. There are two types of filter, one for incoming information and one for outgoing information. Outgoing filters are in the form <em>CALLSIGN.pl</em> and incoming filters are in the form <em>in_CALLSIGN.pl</em>. Filters can be set for both nodes and users.
-
-<P>
-All filters work in basically the same way. There are several elements delimited by commas.
-There can be many lines in the filter and they are read from the top by the program.
-When writing a filter you need to think carefully about just what you want to achieve. You
-are either going to write a filter to <em>accept</em> or to <em>reject</em>.
-Think of a filter as having 2 main elements. For a reject filter, you would have a line
-or multiple lines rejecting the things you do not wish to receive and then a default
-line accepting everything else that is not included in the filter. Likewise, for an
-accept filter, you would have a line or multiple lines accepting the things you wish
-to receive and a default line rejecting everthing else.
-
-<P>
-In the example below, a user requires a filter that would only return SSB spots
-posted in Europe on the HF bands. This is achieved by first rejecting the CW section
-of each HF band and rejecting all of VHF, UHF etc based on frequency.
-Secondly, a filter rule is set based on CQ zones to only accept spots posted in
-Europe. Lastly, a default filter rule is set to reject anything outside the filter.
-
-<tscreen><verb>
-$in = [
- [ 0, 0, 'r', # reject all CW spots

-The actual elements of each filter are described more fully in the following sections.
+If you use isolate on a node connection you will continue to receive
+all information from the isolated partner, however you will not pass
+any information back to the isolated node. There are times when you
+would like to forward only spots across a link (maybe during a contest
+for example). To do this, isolate the node in the normal way and use
+an <em>acc/spot >call< all</em filter in the
+to override the isolate.
-<sect1>Spots
-
-<P>
-The elements of the Spot filter are ....
-
-<tscreen><verb>
-[action, field_no, sort, possible_values, hops]
-</verb></tscreen>
-
-<P>
-There are 3 elements here to look at. Firstly, the action element. This is very simple and only 2 possible states exist, accept (1) or drop (0).
-
-<P>
-The second element is the field_no. There are 13 possiblities to choose from here ....
-
-<tscreen><verb>
- 0 = frequency
- 1 = call
- 2 = date in unix format
- 3 = comment
- 4 = spotter
- 5 = spotted dxcc country
- 6 = spotter's dxcc country
- 7 = origin
- 8 = spotted itu
- 9 = spotted cq
- 10 = spotter's itu
- 11 = spotter's cq
- 12 = callsign of the channel on which the spot has appeared
-</verb></tscreen>
-
-<P>
-The third element tells us what to expect in the fourth element. There are 4 possibilities ....
-
-<tscreen><verb>
- n - numeric list of numbers e.g. [ 1,2,3 ]
- r - ranges of pairs of numbers e.g. between 2 and 4 or 10 to 17 - [ 2,4, 10,17 ]
- a - an alphanumeric regex
- d - the default rule
-</verb></tscreen>
-
-<P>
-The fifth element is simply the hops to set in this filter. This would only be used if the filter was for a node of course and overrides the hop count in hop_table.pl.
-
-<P>
-So, let's look at an example spot filter. It does not matter in the example who the filter is to be used for.
-So, what do we need in the filter? We need to filter the spots the user/node requires and also set a default rule for anything else outside the filter. Below is a simple filter that stops spots arriving from outside Europe.
-
-<tscreen><verb>$in = [
- [ 0, 4, 'a', '^(K|N|A|W|VE|VA|J)'], # 0 = drop, 'a' = alphanumeric
- [ 1, 0, 'd', 0, 1 ], # 1 = want, 'd' = everything else
- ];
-</verb></tscreen>
-
-<P>
-So the filter is wrapped in between a pair of square brackets. This tells Spider to look in between these limits. Then each line is contained within its own square brackets and ends with a comma.
-Lets look carefully at the first line. The first element is 0 (drop). Therefore anything we put on this line will not be accepted. The next element is 4. This means we are filtering by the spotter. The third element is the letter "a" which tells the program to expect an alphanumeric expression in the fourth element. The fourth element is a list of letters separated by the pipe symbol.
-
-<P>
-What this line does is tell the program to drop any spots posted by anyone in the USA, Canada or Japan.
-
-<P>
-The second line is the default rule for anything else. The "d" tells us this and the line simply reads... accept anything else.
-
-<P>
-You can add as many lines as you need to complete the filter but if there are several lines of the same type it is neater to enclose them all as one line. An example of this is where specific bands are set. We could write this like this ....
-
-<tscreen><verb>
-[ 0,0,'r',[1800.0, 2000.0], 1],
-[ 0,0,'r',[10100.0, 10150.0], 1],
-[ 0,0,'r',[14000.0, 14350.0], 1],
-[ 0,0,'r',[18000.0, 18200.0], 1],
-</verb></tscreen>
-
-<P>
-But the line below achieves the same thing and is more efficient ....
-
-<tscreen><verb>
- [ 0, 0, 'r',
- [
- 1800.0, 2000.0, # top band
- 10100.0, 10150.0, # WARC
- 14000.0, 14350.0, # 20m
- 18000.0, 18200.0, # WARC

+From version 1.48 onwards the interface to this has changed. You can now
+use the commands <em>set/badword</em> to add words that you are not prepared
+to see on the cluster, <em>unset/badword</em> to allow that word again and
+<em>show/badword</em> to list the words that you have set.
-<P>
-Again, this is simply a list of names we do not want to see in the spotted field of a DX callout.
+<p>
+If you have a previous <em>/spider/data/badwords</em>, the first time you start
+the node, it will read and convert this file to the new commands. The old style
+file will then be removed.
+<sect1>Stopping (possibly bad) DX Spots from Nodes or Spotters
-<sect>Information, files and useful programs
+<p>
+There are a number of commands that control whether a spot progresses
+any further by regarding it as "bad" in some way.
-<sect1>MOTD
+<p>
+A DX Spot has a number of fields which can checked to see whether they
+contain "bad" values, they are: the DX callsign itself, the Spotter and
+the Originating Node.
-<P>
-One of the more important things a cluster sysop needs to do is to get information to his users. The simplest way to do this is to have a banner that is sent to the user on login. This is know as a "message of the day" or "motd". To set this up, simply create a file in /spider/data called motd and edit it to say whatever you want. It is purely a text file and will be sent automatically to anyone logging in to the cluster.
+<p>
+There are a set of commands which allow the sysop to control whether a
+spot continues:-
-<sect1>Downtime message
+<tscreen><verb>
+set/baddx
+set/badspotter
+set/badnode
+</verb></tscreen>
-<P>
-If for any reason the cluster is down, maybe for upgrade or maintenance but the machine is still running, a message can be sent to the user advising them of the fact. This message lives in the /spider/data directory and is called "offline". Simply create the file and edit it to say whatever you wish. This file will be sent to a user attempting to log into the cluster when DXSpider is not actually running.
+These work in the same as the <em>set/badword</em> command, you can add
+any words or callsigns or whatever to the appropriate database. For
+example, to stop a spot from a particular node you do:
-<sect1>Other text messages
+<tscreen><verb>
+set/badnode gb7djk gb7dxc
+</verb></tscreen>
-<P>
-You can set other text messages to be read by the user if they input the file name. This could be for news items or maybe information for new users. To set this up, make a directory under /spider called <em>packclus</em>. Under this directory you can create files called <em>news</em> or <em>newuser</em> for example. In fact you can create files with any names you like. These can be listed by the user with the command ....
+a bad spotter:
<tscreen><verb>
-show/files
+set/badspotter b0mb p1rat nocall
</verb></tscreen>
-They can be read by the user by typing the command ....
+and some bad dx:
<tscreen><verb>
-type news
+set/baddx video wsjt
</verb></tscreen>
-If the file they want to read is called <em>news</em>. You could also set an alias for this in the Alias file to allow them just to type <em>news</em>
+You can remove a word using the appropriate unset command
+(<em>unset/baddx, unset/badspotter, unset/badnode</em>) or list them
+using one of <em>show/baddx, show/badspotter</em> and
+<em>show/badnode</em>.
+
+<sect>Mail
<P>
-You can also store other information in this directory, either directly or nested under directories. One use for this would be to store DX bulletins such as the OPDX bulletins. These can be listed and read by the user. To keep things tidy, make a directory under /spider/packclus called <em>bulletins</em>. Now copy any OPDX or similar bulletins into it. These can be listed by the user in the same way as above using the <em>show/files</em> command with an extension for the bulletins directory you have just created, like this ....
+DXSpider deals seamlessly with standard AK1A type mail. It supports both
+personal and bulletin mail and the sysop has additional commands to ensure
+that mail gets to where it is meant. DXSpider will send mail almost
+immediately, assuming that the target is on line. However, only one
+mail message is dealt with at any one time. If a mail message is already
+being sent or recieved, then the new message will be queued until it has
+finished.
-<tscreen><verb>
-show/files bulletins
-</verb></tscreen>
+The cluster mail is automatically deleted after 30 days unless the sysop
+sets the "keep" flag using the <em>msg</em> command.
-<P>
-An example would look like this ....
+<sect1>Personal mail
-<tscreen><verb>

+<P>
+Personal mail is sent using the <em>sp</em> command. This is actually the
+default method of sending mail and so a simple <em>s</em> for send will do.
+A full list of the send commands and options is in the <em>command set</em>
+section, so I will not duplicate them here.
-You can see that in the files area (basically the packclus directory) there is a file called <em>news</em> and a directory called <em>bulletins</em>. You can also see that dates they were created. In the case of the file <em>news</em>, you can also see the time it was last modified, a good clue as to whether the file has been updated since you last read it. To read the file called <em>news</em> you would simply issue the command ....
+<sect1>Bulletin mail
-<tscreen><verb>
-type news
-</verb></tscreen>
+<P>
+Bulletin mail is sent by using the <em>sb</em> command. This is one of the
+most common mistakes users make when sending mail. They send a bulletin
+mail with <em>s</em> or <em>sp</em> instead of <em>sb</em> and of course
+the message never leaves the cluster. This can be rectified by the sysop
+by using the <em>msg</em> command.
-To look what is in the bulletins directory you issue the command ....
+<P>Bulletin addresses can be set using the Forward.pl file.

+<sect1>Forward.pl
-You can now read any file in this directory using the type command, like this ....
+<P>
+DXSpider receives all and any mail sent to it without any alterations needed
+in files. Because personal and bulletin mail are treated differently, there
+is no need for a list of accepted bulletin addresses. It is necessary, however,
+to tell the program which links accept which bulletins. For example, it is
+pointless sending bulletins addresses to "UK" to any links other than UK
+ones. The file that does this is called forward.pl and lives in /spider/msg.
+At default, like other spider files it is named forward.pl.issue. Rename it
+to forward.pl and edit the file to match your requirements.
+The format is below ...
<tscreen><verb>
-type bulletins/opdx391

+#

+
+Simply insert a bulletin address and state in the brackets where you wish
+that mail to go. For example, you can see here that mail sent to "UK" will
+only be sent to the UK links and not to PA4AB-14.
+
+<P>
+To force the cluster to reread the file use load/forward
+
+
+<sect1>The msg command
+
+<P>
+The <em>msg</em> command is a very powerful and flexible tool for the
+sysop. It allows the sysop to alter to and from fields and make other
+changes to manage the cluster mail.
+
+Here is a full list of the various options ...
+
+<tscreen><verb>
+ MSG TO <msgno> <call> - change TO callsign to <call>
+ MSG FRom <msgno> <call> - change FROM callsign to <call>
+ MSG PRrivate <msgno> - set private flag
+ MSG NOPRrivate <msgno> - unset private flag
+ MSG RR <msgno> - set RR flag
+ MSG NORR <msgno> - unset RR flag
+ MSG KEep <msgno> - set the keep flag (message won't be deleted ever)
+ MSG NOKEep <msgno> - unset the keep flag
+ MSG SUbject <msgno> <new> - change the subject to <new>
+ MSG WAittime <msgno> - remove any waiting time for this message
+ MSG NOREad <msgno> - mark message as unread
+ MSG REad <msgno> - mark message as read
+ MSG QUeue - queue any outstanding bulletins
+ MSG QUeue 1 - queue any outstanding private messages
+</verb></tscreen>
+
+These commands are simply typed from within the cluster as the sysop user.
+
+<sect1>Message status
+
+<P>
+You can check on a message from within the cluster by using the command
+<em>stat/msg</em>. This will give you additional information on the
+message number including which nodes have received it, which node it
+was received from and when etc. Here is an example of the output of
+the command ...
+
+<tscreen><verb>

+
+<sect1>Filtering mail
+
+<P>
+This is described in the section on <em>Other filters</em> so I will not
+duplicate it here.
+
+<sect1>Distribution lists
+
+<P>
+Distribution lists are simply a list of users to send certain types of
+mail to. An example of this is mail you only wish to send to other
+sysops. In /spider/msg there is a directory called <em>distro</em>. You
+put any distibution lists in here. For example, here is a file called
+SYSOP.pl that caters for the UK sysops.
+
+<tscreen><verb>
+qw(GB7TLH GB7DJK GB7DXM GB7CDX GB7BPQ GB7DXN GB7MBC GB7MBC-6 GB7MDX
+ GB7NDX GB7SDX GB7TDX GB7UDX GB7YDX GB7ADX GB7BAA GB7DXA GB7DXH
+ GB7DXK GB7DXI GB7DXS)
+</verb></tscreen>
+
+Any mail sent to "sysop" would only be sent to the callsigns in this list.
+
+<sect1>BBS interface
+
+<P>
+Spider provides a simple BBS interface. No input is required from the sysop
+of the cluster at all. The BBS simply sets the cluster as a BBS and pushes
+any required mail to the cluster. No mail can flow from Spider to the BBS,
+the interface is one-way.
+
+<P>
+Please be careful not to flood the cluster network with unnecessary mail.
+Make sure you only send mail to the clusters that want it by using the
+Forward.pl file very carefully.
+
+<sect>Scripts
+
+<p>
+From 1.48 onwards it will become increasingly possible to control DXSpider's
+operation with scripts of various kinds.
+
+<p>
+In the first instance, in 1.48, the sysop can create, with their favorite
+text editor, files in the directory <em>/spider/scripts</em> which contain
+any legal command for a callsign or class of connection which will be executed
+at logon.
+
+<p>
+The filename are the callsign of the connection that you want the script to
+operate on, eg: <em>/spider/scripts/g1tlh</em>. The filenames are always in
+lower case on those architectures where this makes a difference.
+
+<p>
+In addition to the callsign specific scripts there are three others:-
+
+<tscreen><verb>
+startup
+user_default
+node_default
+</verb></tscreen>
+
+The <em>startup</em> script is executed immediately after all
+initialisation of the node is done, but before any connections are
+possible.
+
+<p>
+The <em>user_default</em> script is executed for every user that does
+<bf>NOT</bf> already have a specific script.
+
+<p>
+The <em>node_default</em> script is executed for every node that doesn't
+have a specific script.
+
+<p>
+There are a couple of examples in the <em>/spider/scripts</em> directory.
+
+<sect>Databases
+
+<P>
+Spider allows the creation of local or remote databases. It supports
+chained databases, allowing several different databases to be scanned
+with one simple command. Importing of databases is limited at present
+to the standard AK1A databases such as OBLAST and the DB0SDX QSL
+database but will expand with time.
+
+<sect1>Creating databases
+
+<P>
+Creating a database could not be more simple. All the commands are
+sent from the cluster prompt as the <em>sysop</em> user.
+
+To create a database you use the command <em>dbcreate</em>. It can
+be used in 3 different ways like so ..
+
+<tscreen><verb>
+dbcreate <name>
+</verb></tscreen>
+
+To simply create a database locally, you just tell the command the
+name of the database. This does not create the actual database, it
+simply defines it to say that it exists.
+
+<tscreen><verb>
+dbcreate <name> chain <name> [<name>...]
+</verb></tscreen>
+
+This creates a chained database entry. The first database will be
+scanned, then the second, the third etc...
+
+<tscreen><verb>
+dbcreate <name> remote <name>
+</verb></tscreen>
+
+This creates a remote entry. the first name field is the database
+name at the remote node, then the remote switch, then the actual
+node_call of the remote node, for example...
+
+<tscreen><verb>
+dbcreate buckmaster remote gb7dxc
+</verb></tscreen>
+
+Remote databases cannot be chained, however, the last database in a
+chain can be a remote database.
+
+<sect1>Importing databases
+
+<P>
+The only databases that Spider can currently import are the standard
+AK1A databases such as OBLAST or the DB0SDX qsl and address database.
+This will be added to with time.
+
+To import such a database, first put the file somewhere useful like /tmp
+and then issue the following command ...
+
+<tscreen><verb>
+dbimport oblast /tmp/OBLAST.FUL
+</verb></tscreen>
+
+This will update the existing local oblast database or create it if
+it does not exist.
+
+<sect1>Checking available databases
+
+<P>
+Once a database is created, you will want to check that it has been
+added. To do this use the <em>dbavail</em> command. This will
+output the available databases. For example ...
+
+<tscreen><verb>
+dbavail
+DB Name Location Chain
+qsl Local
+buck GB7ADX
+hftest GB7DXM
+G0VGS de GB7MBC 3-Feb-2001 1925Z >
+</verb></tscreen>
+
+<sect1>Looking up databases
+
+<P>
+To look for information in a defined database, simply use the <em>dbshow</em>
+command, for example ...
+
+<tscreen><verb>
+dbshow buckmaster G0YLM
+</verb></tscreen>
+
+will show the information for the callsign G0YLM from the buckmaster
+database if it exists. To make things more standard for the users
+you can add an entry in the Aliases file so that it looks like a standard
+<em>show</em> command like this ...
+
+<tscreen><verb>
+'^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
+</verb></tscreen>
+
+Now you can simply use show/buckmaster or an abreviation.
+
+<sect1>Removing databases
+
+<P>
+To delete an existing database you use the <em>dbremove</em> command.
+For example ...
+
+<tscreen><verb>
+dbremove oblast
+</verb></tscreen>
+
+would remove the oblast database and its associated datafile from the
+system. There are no warnings or recovery possible from this command.
+If you remove a database it ceases to exist and would have to be created
+from scratch if you still required it.
+
+<sect>Information, files and useful programs
+
+<sect1>MOTD
+
+<P>
+One of the more important things a cluster sysop needs to do is to get
+information to his users. The simplest way to do this is to have a banner
+that is sent to the user on login. This is know as a "message of the day"
+or "motd". To set this up, simply create a file in /spider/data called motd
+and edit it to say whatever you want. It is purely a text file and will be
+sent automatically to anyone logging in to the cluster.
+
+<sect1>Downtime message
+
+<P>
+If for any reason the cluster is down, maybe for upgrade or maintenance but
+the machine is still running, a message can be sent to the user advising them
+of the fact. This message lives in the /spider/data directory and is called
+"offline". Simply create the file and edit it to say whatever you wish.
+This file will be sent to a user attempting to log into the cluster when
+DXSpider is not actually running.
+
+<sect1>Other text messages
+
+<P>
+You can set other text messages to be read by the user if they input the file
+name. This could be for news items or maybe information for new users.
+To set this up, make a directory under /spider called <em>packclus</em>.
+Under this directory you can create files called <em>news</em> or <em>newuser</em>
+for example. In fact you can create files with any names you like. These can
+be listed by the user with the command ....
+
+<tscreen><verb>
+show/files
+</verb></tscreen>
+
+They can be read by the user by typing the command ....
+
+<tscreen><verb>
+type news
+</verb></tscreen>
+
+If the file they want to read is called <em>news</em>. You could also set
+an alias for this in the Alias file to allow them just to type <em>news</em>
+
+<P>
+You can also store other information in this directory, either directly or
+nested under directories. One use for this would be to store DX bulletins
+such as the OPDX bulletins. These can be listed and read by the user.
+To keep things tidy, make a directory under /spider/packclus called
+<em>bulletin</em>. Now copy any OPDX or similar bulletins into it. These
+can be listed by the user in the same way as above using the <em>show/files</em>
+command with an extension for the bulletin directory you have just created,
+like this ....
+
+<tscreen><verb>
+show/files bulletin
+</verb></tscreen>
+
+<P>
+An example would look like this ....
+
+<tscreen><verb>
+sh/files
+bulletin DIR 20-Dec-1999 1715Z news 1602 14-Dec-1999 1330Z
+</verb></tscreen>
+
+You can see that in the files area (basically the packclus directory) there is a
+file called <em>news</em> and a directory called <em>bulletin</em>. You can
+also see that dates they were created. In the case of the file <em>news</em>,
+you can also see the time it was last modified, a good clue as to whether the
+file has been updated since you last read it. To read the file called
+<em>news</em> you would simply issue the command ....
+
+<tscreen><verb>
+type news
+</verb></tscreen>
+
+To look what is in the bulletin directory you issue the command ....

+In later versions of Spider a simple console program is provided for the sysop.
+This has a type ahead buffer with line editing facilities and colour for spots,
+announces etc. To use this program, simply use console.pl instead of client.
+
+<P>
+To edit the colours, copy /spider/perl/Console.pl to /spider/local and edit the
+file with your favourite editor.
+
+<sect1>Updating kepler data
+
+<P>
+Spider has a powerful and flexible show/satellite command. In order for
+this to be accurate, the kepler data has to be updated regularly. In
+general, this data is available as an email or via cluster mail.
+Updating it is simple. First you need to export the mail message as a
+file. You do this with the <em>export</em> command from the cluster prompt
+as the sysop. For example ...
<tscreen><verb>
-#
-# this is an example message forwarding file for the system
-#
-# The format of each line is as follows
-#
-# type to/from/at pattern action destinations
-# P/B/F T/F/A regex I/F [ call [, call ...] ]
-#
-# type: P - private, B - bulletin (msg), F - file (ak1a bull)
-# to/from/at: T - to field, F - from field, A - home bbs, O - origin
-# pattern: a perl regex on the field requested
-# action: I - ignore, F - forward
-# destinations: a reference to an array containing node callsigns
-#
-# if it is non-private and isn't in here then it won't get forwarded
-#
-# Currently only type B msgs are affected by this code.
-#
-# The list is read from the top down, the first pattern that matches
-# causes the action to be taken.
-#
-# The pattern can be undef or 0 in which case it will always be selected
-# for the action specified
-#
-# If the BBS list is undef or 0 and the action is 'F' (and it matches the
-# pattern) then it will always be forwarded to every node that doesn't have
-# it (I strongly recommend you don't use this unless you REALLY mean it, if
-# you allow a new link with this on EVERY bull will be forwarded immediately
-# on first connection)
-#
+export 5467 /spider/perl/keps.in
+</verb></tscreen>
+
+would export message number 5467 as a file called keps.in in the
+/spider/perl directory.
+
+Now login to a VT as sysop and cd /spider/perl. There is a command in
+the perl directory called <em>convkeps.pl</em>. All we need to do now is
+convert the file like so ...
+
+<tscreen><verb>
+./convkeps.pl keps.in
+</verb></tscreen>
+
+Now go back to the cluster and issue the command ...
+
+<tscreen><verb>
+load/keps
+</verb></tscreen>
+
+That is it! the kepler data has been updated.
+
+<sect1>The QRZ callbook
+
+<P>
+The command <em>sh/qrz</em> will only work once you have followed a few
+simple steps. First you need to get a user ID and password from qrz.com.
+Simply go to the site and create one. Secondly you need to copy the file
+/spider/perl/Internet.pm to /spider/local and alter it to match your user
+ID and password. You also at this point need to set $allow=1 to complete
+the setup. Many thanks to Fred Lloyd, the proprieter of
+<htmlurl url="http://www.qrz.com" name="qrz.com"> for allowing this access.
+
+<sect>CVS
+
+<P>
+CVS stands for "Concurrent Versions System" and the CVS for DXSpider is held
+at <htmlurl url="http://www.sourceforge.net" name="Sourceforge">. This means
+that it is possible to update your DXSpider installation to the latest
+sources by using a few simple commands.
+
+<P>
+THIS IS NOT FOR THE FAINT HEARTED!!! ONLY DO THIS IF YOU HAVE A TEST
+INSTALLATION OR ARE WILLING TO HAVE YOUR CLUSTER CRASH ON YOU!!!
+THIS MUST BE CONSIDERED AT LEAST BETA TESTING AND MAYBE EVEN ALPHA!!
+YOU HAVE BEEN WARNED!!!
+
+<P>
+DID I MENTION..... ONLY DO THIS IF YOU ARE WILLING TO ACCEPT THE
+CONSEQUENCES!!!
+
+<P>
+I am of course assuming that you have a machine with both DXSpider and
+Internet access running.
+
+<P>
+BEFORE YOU EVEN CONSIDER STARTING WITH THIS MAKE A BACKUP OF YOUR
+ENTIRE SPIDER TREE!!
+
+<P>
+Assuming you are connected to the Internet, you need to login to the
+CVS repository and then update your Spider source. There are several
+steps which are listed below ...
+
+<P>
+First login as the user <em>sysop</em>. Next you need to connect to the CVS
+repository. You do this with the command below ...
+
+<verb>
+cvs -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider login
+</verb>
+
+You will get a password prompt. Simply hit return here and your machine should
+return to a normal linux prompt.
+
+<P>
+What happens next depends on whether you have an existing installation that
+you want to update with the latest and greatest or whether you just want
+to see what is there and/or run it on a new machine for testing.
+
+If you are installing Spider from CVS then change directory to /home/sysop
+
+If you are wanting to update Spider then cd to /tmp
+
+<P>
+The next step will create a brand new 'spider' directory in your current
+directory.
+
+<verb>
+cvs -z3 -d:pserver:anonymous@cvs.DXSpider.sourceforge.net:/cvsroot/dxspider co spider
+</verb>
+
+This command is all on one line.
+
+<P>
+Hopefully your screen should show you downloading files. The -z3 simply compresses
+the download to improve speed.
+When this has finished, you will have exactly the same as if you had untarred a full
+tarball PLUS some extra directories and files that CVS needs to do the magic that
+it does.
+
+<P>
+Now if you are doing a new installation, that's it. Carry on as if you have
+just downloaded and untarred the lastest tarball.
+
+<P>
+If you want to upgrade your current installation then do this ...
+
+<tscreen><verb>
+tar cvfz /tmp/s.tgz spider
+cd /
+tar xvfzp /tmp/s.tgz
+</verb></tscreen>
+
+This is assuming you downloaded to the /tmp directory of course.
+
+<P>
+NOTE: the 'p' on the end of the 'xvfz' is IMPORTANT! It keeps the permissions
+correct. YOU WERE LOGGED IN AS THE USER SYSOP WEREN'T YOU?????
+
+Remember to recompile the C client (cd /spider/src; make)
+
+<P>
+At this point the files have been upgraded. You can (usually) restart the cluster
+in your own time. However, if you attempt to use any new commands or features
+expect it to be fatal! At least your cluster will have been restarted then so it
+will be too late to worry about it!
+
+<P>
+Now the magic part! From now on when you want to update, simply connect to the
+Internet and then, as the user <em>sysop</em> ...
+
+<tscreen><verb>
+cd /spider
+cvs -z3 update -d
+</verb></tscreen>
+
+and your files will be updated. As above, remember to recompile the "C" client
+if it has been updated (CVS will tell you) and restart if any of the perl scripts
+have been altered or added, again, CVS will tell you.
+
+<P>
+You will find any changes documented in the /spider/Changes file.
+
+<sect>The DXSpider command set
+
+<P>
+Below is a complete list of commands available from the cluster prompt.
+Most maintenance tasks are automatic but there are some commands that are useful
+for a sysop. These are listed below in alphabetical order. The number in
+brackets following the command name is the permissions level needed to use
+the command.

+entry<newline>
+</tt>
+
+<P>
+DBCREATE allows you to define a database in the system. It doesn't actually
+create anything, just defines it.
+
+The databases that are created are simple DB_File hash databases, they are
+therefore already 'indexed'.
+
+You can define a local database with the first form of the command eg:
+
+ DBCREATE oblast
+
+You can also chain databases with the addition of the 'chain' keyword.
+This will search each database one after the other. A typical example
+is:
+
+ DBCREATE sdx_qsl chain sql_ad
+
+No checking is done to see if the any of the chained databases exist, in
+fact it is usually better to do the above statement first then do each of
+the chained databases.
+
+Databases can exist offsite. To define a database that lives on another
+node do:
+
+ DBCREATE buckmaster remote gb7dxc
+
+Remote databases cannot be chained; however, the last database in a
+a chain can be a remote database eg:
+
+ DBCREATE qsl chain gb7dxc
+
+To see what databases have been defined do:
+
+ DBAVAIL (or it will have been aliased to SHOW/COMMAND)
+
+It would be normal for you to add an entry into your local Aliases file
+to allow people to use the 'SHOW/<dbname>' style syntax. So you would
+need to add a line like:-
+
+<tscreen><verb>
+ 's' => [
+ ..
+ ..
+ '^sh\w*/buc', 'dbshow buckmaster', 'dbshow',
+ ..
+ ..
+ ],
+</verb></tscreen>
+
+to allow
+
+ SH/BUCK g1tlh

+
+ DBIMPORT oblast /tmp/OBLAST.FUL
+
+will import the standard OBLAST database that comes with AK1A into the

+
+For example:
+
+ DBREMOVE oblast
+
+will remove the oblast database from the system and it will also remove

+so that users can use the more familiar AK1A style of enquiry such as:
+
+<tscreen><verb>
+ SH/BUCK G1TLH
+</verb></tscreen>
+
+but if he hasn't and the database really does exist (use DBAVAIL or

+
+If the file already exists it will be renamed to <filename>.o. In fact
+up to 5 generations of the file can be kept each one with an extra 'o' on the

+This command sends all the latitude and longitude information that your
+cluster is holding against callsigns. One advantage of recieving this
+information is that more locator information is held by you. This
+means that more locators are given on the DX line assuming you have
+<em>set/dxgrid</em> enabled. This could be a LOT of information though, so
+it is not recommended on slow links.

+counter which is decremented on every outgoing ping and then reset to
+the 'obscount' value on every incoming ping. The default value of this
+parameter is 2.
+
+What this means is that a neighbouring node will be pinged twice at
+(default) 300 second intervals and if no reply has been heard just before
+what would be the third attempt, that node is disconnected.
+
+If a ping is heard then the obscount is reset to the full value. Using

+You can use this command to set a different interval. Please don't.
+But if you do the value you enter is treated as minutes up 60 and seconds

-Send some arbitrary text to a locally connected callsign. No processing is done on

+This command allow you to estimate the likelihood of you contacting
+a station with the prefix you have specified. The output assumes a modest
+power of 20dBW and receiver sensitivity of -123dBm (about 0.15muV/10dB SINAD)
+
+The result predicts the most likely operating frequencies and signal
+levels for high frequency (shortwave) radio propagation paths on
+specified days of the year and hours of the day. It is most useful for
+paths between 250 km and 6000 km, but can be used with reduced accuracy
+for paths shorter or longer than this.
+
+The command uses a routine MINIMUF 3.5 developed by the U.S. Navy and
+used to predict the MUF given the predicted flux, day of the year,
+hour of the day and geographic coordinates of the transmitter and
+receiver. This routine is reasonably accurate for the purposes here,
+with a claimed RMS error of 3.8 MHz, but much smaller and less complex
+than the programs used by major shortwave broadcasting organizations,
+such as the Voice of America.
+
+The command will display some header information detailing its
+assumptions, together with the locations, latitude and longitudes and
+bearings. It will then show UTC (UT), local time at the other end
+(LT), calculate the MUFs, Sun zenith angle at the midpoint of the path
+(Zen) and the likely signal strengths. Then for each frequency for which
+the system thinks there is a likelihood of a circuit it prints a value.
+
+The value is currently a likely S meter reading based on the conventional
+6dB / S point scale. If the value has a '+' appended it means that it is
+1/2 an S point stronger. If the value is preceeded by an 'm' it means that
+there is likely to be much fading and by an 's' that the signal is likely
+to be noisy.
+
+By default SHOW/MUF will show the next two hours worth of data. You
+can specify anything up to 24 hours worth of data by appending the no of
+hours required after the prefix. For example:-
- pc gb7djk PC33^GB7TLH^GB7DJK^400^

-Connect a node to your system in such a way that you are a full protocol

+to the locator. For example:-
-You can potentially connect several nodes in this way.

-From version 1.35 onwards neighbouring nodes are pinged at regular intervals (see

+Each pass in a period is separated with a row of '-----' characters
-What this means is that a neighbouring node will be pinged twice at
-(default) 300 second intervals and if no reply has been heard just before
-what would be the third attempt, that node is disconnected.
+So for example:-
-If a ping is heard then the obscount is reset to the full value. Using
-default values, if a node has not responded to a ping within 15 minutes,

+
+If you know that G3JNB is likely to be present on GB7TLH, but you can only

+second form of the talk message.
+
+If you want to have a ragchew with someone you can leave the text message
