-<P>So, the first connection is made by Spider. This is fine as Spider uses the Net_Telnet
-script from within perl. This actually uses TCP rather than TELNET so no negotiation
-will be done on the first connection. Once connected to mary.lancs.ac.uk, the command
-is sent to suppress echo. Now a telnet is made to a cluster node that is accepting
-connections on port 23. The problem with this link is that the negotiation is made by
-the remote machine, therefore you have no control over it. The chances are that this
-link will create echo and there will be no way you can stop it.

-<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.
-<P>
-<H3>Autostarting the cluster</H3>
-
-<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.
-<P>
-<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 ...

-##Start DXSpider on bootup and respawn it should it crash

-<P>This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart it should it crash for any reason.
-<P>
-<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.
-<P>
-<P>So far so good, now to automate script connections...
-<P>
-<H3>The crontab file</H3>
-
-<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)
-<P>

-# check every 10 minutes to see if gb7xxx is connected and if not
-# start a connect job going

-<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.
