SUMMARY: Still having check_by_ssh problems

[Blair Rampling]

The problem with check_by_ssh not passing exit codes was not caused by the plugin itself. The version of SSH included with Solaris 9 (Sun SSH 1.0) has a bug where exit codes are either passed as 0 or 255. By removing the stock Solaris 9 SSH and adding OpenSSH 3.5v1 it works properly. OpenSSH 3.4 is also verified to work properly.

It seems check_by_ssh isn't passing the exit codes.

Remote:

bash-2.05$ /usr/local/nagios/libexec/check_by_ssh -f -l sysadmin -H vanapps3 -C '~/plugins/check_psproc.pl fin84prd 48'
CRITICAL Incorrect number of processes (      63)
bash-2.05$ echo $?
0
bash-2.05$ 

Local:

bash-2.03$ plugins/check_psproc.pl fin84prd 48
CRITICAL Incorrect number of processes (      63)
bash-2.03$ echo $?
2

This is what I get when I execute from the Nagios host as nagios user a
remote check_disk:

$ ./libexec13b2/check_by_ssh -H w.x.y.z -l nagios -i
/usr/local/nagios/.ssh/id_rsa -C /usr/local/nagios/libexec/check_disk -w 80%
-c 70% -m -p /export/home
DISK CRITICAL - [10421765 kB (64%) free on /export/home]
$ echo $?
2

What is the result when you call your checks as nagios user from your nagios
host from the command line? Can you send an example?
