Solution needed - nagios + windows 2008 with nsclient++

[mkiler1]

hello,
I have working nagios and I'm able to receive information from Windows 2008 machine using nsclient++.
But now I would like to monitor from this Windows machine remote port on remote machine. Monitor - only check like telnet, I need check only that they can respond.
Please tell me how to do that. I can do that on linux using NRPE, but I don't have idea how to do that on Windows

You'll need to find applicable Windows plugins that can do this, or write your own. The best place to look is @ https://exchange.nagios.org

From there, you'll want to use the external scripts section in NSClient++ to 'proxy' your checks through this Windows Machine. Nagios executes check_nrpe -> your windows server evaluates what command was called -> your windows command then executes whatever script you're after.

It sounds like a bit more work than needed, but if you really need to jump through the host then I understand. It'll take some testing on your end to get it working fully. This document might help you - https://assets.nagios.com/downloads/nag ... ios-XI.pdf

ok, thanks, for links
But is someone here who is doing this? I can't write my own script

What I need - check smtp on port 25 but directly from host which conecting to this smtp, not from other host with nagios,
