Summary: Check_by_ssh exit code always 0

Initial Comment:
The "check_by_ssh" plugin report always an exit status/code of 0 when it should return a value of "2".
Should be the same for the other exit code values.

Plugin compiled from nagios-plugins-1.4.7.tar.gz on a RedHat Fedora Core Intel system.

Best regards

Hello alain,

I've looked into this issue and can reproduce the described behaviour..
But: check_by_ssh's -f
argument simply adds -f to the ssh call. With -f, ssh immediately returns,
even if the remote command is still running. Actually there is no exit code
at this point.

However, check_by_ssh waits for the command output, IMO because it reads
from the output file descriptor which is left open until the remote command
execution is done.

But this is a side effect.

Note that
/usr/bin/ssh -f 127.0.0.1 'exit 2' ;echo $?
also returns 0. I'd thus say check_by_ssh -f works as desi(gn|r)ed

I cannot imagine what -f should be good for though. But we should at least
place
a note in --help.

Any other comments?

Matthias

I forgot to say that the problem only occur when using the "-f" (fork)
option.
