+<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>

+<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>
+
+<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
+<A HREF="http://www.dxcluster.org/cron.html">DXSpider</A> website
+at the cron page where it is explained more fully.</P>
