+From version 1.47 there is a new (more efficient) way of doing this (see next section) but,
+if you prefer, the method of doing it described here will continue to work just fine.
+<P>
<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 ....
<P>
<BLOCKQUOTE><CODE>
<PRE>
-spdlogin 8000/tcp # spider anonymous login port

<P>Then add a line in /etc/inetd.conf like this ....

-<P>This needs to be added above the standard services such as ftp, telnet etc.

+<H2><A NAME="ss3.3">3.3 Setting up telnet connects (from 1.47 onwards)</A>
+</H2>
+
+<P>From version 1.47 you can chose to allow the perl cluster.pl program to
+allow connections direct (i.e. not via the <CODE>/spider/src/client</CODE>
+interface program). If you are using Windows then this is the only method
+available of allowing incoming telnet connections.
+<P>
+<P>To do this you need first to remove any line that you may previously have set
+up in /etc/inetd.conf. Remember to:-
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+killall -HUP inetd
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>
+<P>to make the change happen...
+<P>
+<P>Having done that then you need to copy the file
+<CODE>/spider/perl/Listeners.pm</CODE> to <CODE>/spider/local</CODE> and
+then edit it. You will need to uncomment the line containing "0.0.0.0"
+and select the correct port to listen on. So that it looks like this:-
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+@listen = (
+ ["0.0.0.0", 7300],
+);
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>
+<P>As standard, the listener will listen on all interfaces simultaniously. If you require more
+control than this, you can specify each interface individually:-
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+@listen = (
+ ["gb7baa.dxcluster.net", 7300],
+ ["44.131.16.2", 6300],
+);
+</PRE>
+</CODE></BLOCKQUOTE>
+<P>
+<P>This will only be successful if the IP addresses on each interface are static.
+If you are using some kind of dynamic IP addressing then the 'default' method is the
+only one which will work.
+<P>
+<P>Restart the cluster.pl program to enable the listener.
+<P>
+<P>One important difference with the internal listener is that no echoing is done by the
+cluster program. Users will need to set 'local-echo' on in their telnet clients if
+it isn't set automatically (as per the standards). Needless to say this will probably
+only apply to Windows users.
+<P>
+<H2><A NAME="ss3.4">3.4 Setting up for AGW Engine (1.47 onwards)</A>
+</H2>
+
+<P>AGW Engine is a Windows based ax25 stack. You can connect to an AGW engine from Linux
+as well as Windows based machines.
+<P>
+<P>In order to enable access to an AGW Engine you need to copy <CODE>/spider/perl/AGWConnect.pm</CODE>
+to <CODE>/spider/local</CODE> and edit it. Specifically you must:-
+<P>
+<UL>
+<LI> set <CODE>$enable</CODE> to 1.</LI>
+<LI> set <CODE>$login</CODE> and <CODE>$passwd</CODE> to the values set up in your AGW installation.
+If you haven't set any there, then you should not touch these values.</LI>
+<LI> You can connect to a remote AGW engine (ie on some other machine) by changing <CODE>$addr</CODE>

<P>In order to allow cluster node connections, spider needs to know that the
this is all that needs to be done. If the connection is to be outgoing then
a connection script needs to be written.
