3.7 Automating things -

- -

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. -

-

Autostarting the cluster

- -

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. -

-

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
-DX:3:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
-
-
-

-

This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart -it should it crash for any reason. -

-

As root type the command telinit q. DXSpider should start up -immediately. You will see the output on tty7 and if you login as sysop -you should find everything running nicely. -

-

So far so good, now to automate script connections... -

-

The crontab file

- -

Login as sysop 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) -

-

-
-# 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')
-
-
-

-

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. -

-

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 -DXSpider website -at the cron page where it is explained more fully. -
