Hi I haven't researched this or anything, but is there is a -v option to
check_by_ssh to get the exact error thrown? - I'm simply wondering if you have
a bad/mismatched key in ~/.ssh/known_hosts or authorized_keys (sorry, ive been
too busy to be much help on nagios lately guys)...
Cheers!

Subject: [Nagios-users] Return code of 127 is out of bounds - plugin may be
missing

Greetings, all. I've googled the subject above and evaluated the answers I've
found but haven't yet found info that pinpoints my issue.
I'm running Nagios Core 3.2.1 on RedHat 5.8. This installation has been running
for a few years, I just inherited it's care and maintenance recently. On one of
my monitored servers I write a script "checkRAID.sh" that calls another piece
of code, looks at the results, and returns either a 0 or a 2 (the result will
always be either good or critical, depending on whether the RAID controller is
unhappy).
Nagios runs as user "nagios". The remote machine is configured to allow user
"nagios" to log in without a password, using a key pair. This works.
In /usr/local/nagios/etc/checkcommands.cfg I have :
define command{
command_name check_raid
command_line /usr/local/nagios/libexec/check_by_ssh -H $HOSTNAME -l
nagios -i /home/nagios/.ssh/id_rsa -E -o StrictHostKeyChecking=no -C
/home/nagios/checkRAID.sh
}
When I become nagios ("su - nagios") and run that script, I get:
[nagios@nagios ~]$ /usr/local/nagios/libexec/check_by_ssh -H <remote server IP>
-l nagios -i /home/nagios/.ssh/id_rsa -E -o StrictHostKeyChecking=no -C
/home/nagios/checkRAID.sh
Check failed
[nagios@nagios ~]$ echo $?
2
[nagios@nagios ~]$
That "Check failed" line is what's written to stdout just before returning an
exit code of 2. This shows me that the remote script is working fine, and that
the local nagios user is able to execute it with no problems. However, once I
add an entry to services.cfg to tie this service check to my remote host and
give it time to run the command, when I look at nagios' "Services" page it
shows :
check_raid CRITICAL 06-10-2013 21:17:25 0d 6h 14m
29s 3/3 (Return code of 127 is out of bounds - plugin may be missing)
This has me baffled. The return code is quite clearly 2.
I recently set debug_level to -1 and restarted. I'm hoping that the debug log
will
