<p>At the moment, anybody can connect inwards at any time from outside, either by ax25 or by
telnet (assuming you have followed the instructions in <a href="install.html">installation</a>
<p><em>Connect</em> scripts live in the <tt>/spider/connect</tt> directory and are simple ascii scripts
that are written using a normal editor. There are a couple of examples in the issue directory.
- <p>Here are a couple of basic types, first a telnet connection:-
+ <p>Here are a few of basic types, first a telnet connection where the
+ client is set up in the passwd file thus:-
+ <pre>
+ gb7djk:x:1372:1291::/home/gb7djk:/usr/bin/perl /spider/perl/client.pl gb7djk telnet
+ </pre>
+ and the connect script would be:-
<pre>
timeout 15
# this is a comment
connect telnet dirkl.tobit.co.uk
'login' 'gb7djk'
'word' 'gb7djk'
- client gb7djk-1 telnet
+ client gb7djk telnet
</pre>
- <p>and an ax25 example:-
+ <p>For a connect that requires a login and execution of the programs
+ from a normal shell, do:-
+
+ <pre>
+ timeout 15
+ connect telnet dirkl.tobit.co.uk
+ 'login' 'gb7djk'
+ 'word' 'gb7djk'
+ '\$' 'cd /spider/perl'
+ # set the line to prevent echoing, leaving this out will
+ # confuse whole networks for hours!
+ '\$' 'stty -echo raw'
+ # tell GB7DJK that you are GB7DJK-1
+ '\$' 'client.pl gb7djk-1 telnet'
+ # tell GB7DJK-1 that it is connected to GB7DJK
+ # you can leave this out if you call this script 'gb7djk'
+ client gb7djk telnet
+ </pre>
+
+ <p>and finally an ax25 example:-
<pre>
timeout 60
abort (Busy|Sorry|Fail)
'Connect' 'c np7'
'Connect' 'c gb7dxm'
'Connect' ''
+ # you can leave this out if you call the script 'gb7dxm'
client gb7dxm ax25
</pre>
- <p>A connection is started manually by typing in <tt>connect <scriptname></tt> on a sysop enabled
+ <p>A connection is started manually by typing in <tt>connect <scriptname></tt> on a sysop enabled

- <p>The connect scripts consist of lines which start with the following keywords or symbols:-
+ <p>The connect scripts consist of lines which start with the
+ following keywords or symbols:-
+
<ul>
- <p><li><b>#</b> All lines starting with a <b>#</b> are ignored, as are wholly blank lines.
- <p><li><b>timeout</b> followed by a number is the number of seconds to wait for a command
- to complete. If there is no <b>timeout</b> specified in the script then the default is 60 seconds.
- <P><li><b>abort</b> 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.
- <p><li><b>connect</b> followed by <b>ax25</b> or <b>telnet</b> and some type dependent information. In
- the case of a <b>telnet</b> 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).
- <p>In the case of an <b>ax25</b> session then this would normally be a call to <tt>ax25_call</tt>
- or <tt>netrom_call</tt> as in the example above. It is your responsibility to get your node
- and other ax25 parameters to work before going down this route!
- <p><li><b>'</b> or <b>"</b> are the delimiting characters for a <tt>chat</tt> type script. They 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.
- <p>When the left hand string has found what it is looking (if it is) then the right hand string is
- sent to the connection.

<p>This process is repeated for every line of <tt>chat</tt> script.
- <p><li><b>client</b> 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 <tt>other</tt> which actually
- connects to <tt>GB7DJK-1</tt> [instead of a script called <tt>gb7djk-1</tt>]).
