Yes, indeed.

I have killed them both, however, I can't seem to get the nrpe daemon
running again on the monitored host (the OS is Soalris 10) . This is what I
executed;

*bash$ svcadm enable nrpe
bash$/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d*


Then to verify...

*bash-3.00# svcs | grep nrpe
legacy_run     Jan_09   lrc:/etc/rc3_d/S60nrpe
online         16:39:40 svc:/network/nrpe/tcp:default
maintenance    16:41:16 svc:/application/management/nagios/nrpe:default*

And more verification...

*bash-3.00# netstat -a | grep 5666*


The netstat command above didn't return any output. So this means the NRPE
daemon is either not running or not listening on port 5666.

Am I doing the NRPE start up the right way? Are there other ways to start
NRPE daemon on Solaris 10?


Regards,
Juki
