Package: nagios-nrpe-plugin
Version: 2.15-1
Severity: normal
Running from the shell:
root at monitoring2:/etc/icinga# /usr/lib/nagios/plugins/check_nrpe -H 192.168.5.88 -p 5505 -n -c check_ntp
connect to address 192.168.5.88 port 5505: No route to host
connect to host 192.168.5.88 port 5505: No route to hostroot at monitoring2:/etc/icinga# echo $?
255
Firstly the stderr reports the problem twice, in different ways, and
doesn't terminate the second time with a new line.
Secondly, I needed to run this by hand as all I got reported was
Current Status: CRITICAL
Status Information: Return code 255 is out of bounds
It would have been helpful if the result had been:
Current Status: UNKNOWN
Status Information: No route to host
Note that this is a firewall issue, pinging the host *does* work,
which is why the service check is being done. Also IMHO the firewall
should reject the connection instead of reporting no route to host,
but that's not so relevant to the issue with check_nrps.
Thanks,
Paul
