Monitoring inetd

Roberto Volsa — Wed, 25 Oct 2000 15:46:56 GMT

The objective is create a package which monitors inetd; but inetd is a socket and it only listen: a process born only if a remote request reach the server. Thus: which processes have i to monitor and write down on the configuration files of the package?

inetd will log contact requests, etc. to the files specified in etc/inetd.conf

Hi:

I'm not sure exactly what you want. the inetd daemon will be visible to 'ps' if you want to make sure its running.

You can start inetd with connection logging enabled. The default is not to do so. See "man inetd" for more information. Hopefully this information helps you.

the problem is what i have to write in the SERVICE_CMD! Qhat command does start inetd? I don't think i can put init in SERVICE_CMD raw!

Do I understand that you want a serviceguard package to swap inetd back and forth between primary and failover hosts?

Why?

Inetd should run independently on each box. It is necessary for basic networking functionality.

inetd is started at startup (run level 2 and higher) by the script /sbin/rc2.d/S500inetd with the start parameter.

You can configure your setup so that if inetd dies - it gets restarted:

INETDRUNNING=`ps -ef | grep -c [i]netd`
if [ ! $INETDRUNNING ]
then
/sbin/rc2.d/S500inetd start
fi

Good luck

Hi:

As Alan asked, are you talking about MC/ServiceGuard 'packages'? If so, I agree with him, inetd is not something that you want to start/stop/reconfigure in a failover. A similar thread on this issue can be found here:

Does this help?

Yes, the package has to monitor inetd process; the package is used for load balancing purposes and each package with different ips let the customer know where messages aresent.
