Hey there

If I run the following command line it works:

# /usr/lib64/nagios/plugins/check_ssh -4 -p 1157 104.xxx.xxx.xxx
SSH OK - OpenSSH_5.3 (protocol 2.0) | time=0.132206s;;;0.000000;10.000000

However with the same command line in nrpe.cfg connection is always refused

command[check_remote_ssh]=/usr/lib64/nagios/plugins/check_ssh -4 -p 1157 104.xxx.xxx.xxx

From the GUI

Current Status: CRITICAL (for 2d 13h 11m 42s)
Status Information: Connection refused

I have no doubt it is a configuration issue, but I can't spot it. Any help is appreciated.

Is selinux enabled?

Is "connection refused" coming from the plugin or from NRPE? Try running check_nrpe without the -c argument.

This has now been resolved. I upgraded nagios from 3.5 which yum installed to 4.0.8 by uninstalling and starting from scratch, and it works.

Thanks for your help, all good now.
