I'm implementing ssh proxy based monitoring of windows machines, and it works great until I try to monitor performance counters or services with special characters in them. After some research, I discovered the check_by_ssh plugin in 1.4.13 has a bug with escaped characters.

I don't want to break my nagiosxi distribution.

Is it ok to install the nagios-plugins 1.4.15, or will that be overwritten as updates to nagiosxi come out?

Example:

> /bin/sh -c "echo '"'$PATH'"'"
$PATH
> /bin/sh -c 'echo "a b"'
a b

Unpatched:
> check_by_ssh -H localhost -C "echo '"'$PATH'"'"
/usr/local/bin:/usr/bin/:/bin
> check_by_ssh -H localhost -C 'echo "a b"'
Could not open pipe: /usr/bin/ssh localhost 'echo "a b"'

A simpler way might be to download the new plugin pack, extract, and then just copy or compile the updated plugin that you need. I think the tarball contains most of the plugins already pre-compiled.

thank you - I'll go with that.

You bet, let us know if you run into any problems along the way
