Hi,
I think I have bug a bug in the nagios plugin check_by_ssh v1.39. I have
successfully configured SSH public key-based logins between two of my
servers and on the command-line it works absolutely fine:
nagios at db01:~$ /usr/lib/nagios/plugins/check_by_ssh -l nagcheck -H
10.0.0.30 -C id
uid=10001(nagcheck) gid=100(users) groups=100(users)
As you can see, the plugin successfully shows the output of the "id"
command. However when I try to cat a file I do not get any output at all:
nagios at db01:~$ /usr/lib/nagios/plugins/check_by_ssh -l nagcheck -H
10.0.0.30 -C '/bin/cat /tmp/tw_cli.txt'
I think this is rather strange, because when I use ssh to manually
perform this operation I don't get any error at all (the cat command is
run without any problems):
nagios at db01:~$ ssh -l nagcheck 10.0.0.30 "/bin/cat /tmp/tw_cli.txt"

Any ideas on this? Did I maybe discover a bug in the script?
Thank you very much.
