Public bug reported:
Binary package hint: nagios-plugins-basic
Nagios plugin check_by_ssh doesn't work as expected in passive mode. The
output file is created, but not populated, same check in active mode
completes successfully. Same exact check executed by a newer version of
the plugin, built from source, populates the output file with the result
of the check as expected.
1) The release of Ubuntu, via 'lsb_release -rd':
Description: Ubuntu 8.04.2
Release: 8.04
2) The version of the package, via 'apt-cache policy nagios-plugins-basic':
nagios-plugins-basic:
Installed: 1.4.11-1ubuntu5
Candidate: 1.4.11-1ubuntu5
Version table:
*** 1.4.11-1ubuntu5 0
500 http://ca.archive.ubuntu.com hardy/main Packages
100 /var/lib/dpkg/status
3) What I expect to happen:
When check_by_ssh is ran in passive mode, it should output the result of the
remote check command to the explicitly specified output file. This result
should already be in passive check result format (see below) so it can be
easily appended to Nagios external command file. Here's an example:
$ ./check_by_ssh -H remotehost -n testhost -s apt -C
"/usr/lib/nagios/plugins/check_apt" -O /tmp/result
$ cat /tmp/result
[1242858973] PROCESS_SERVICE_CHECK_RESULT;testhost;apt;0;APT OK: 0 packages
available for upgrade (0 critical updates).
I was able to achieve the desired behaviour by running newer version of
the check_by_ssh plugin, which I manually complied from official 1.4.13
source package.
4) What happened instead:
When I ran the latest binary Hardy (i386) version of the plugin
$ ./check_by_ssh -H remotehost -n testhost -s apt -C
"/usr/lib/nagios/plugins/check_apt" -O /tmp/result
APT OK: 0 packages available for upgrade (0 critical updates). $
The active check result was printed to stdout, but nothing was printed
to /tmp/result. It's almost as if plugin is executing in active, rather
than passive mode.
Not sure if it matters, but I'm running Ubuntu JeOS as VMware gues OS.
I believe this is the source package for this binary package:
