What version of NSclient++ did you install on this server? This is an uncommon error to get unless you are actually running a command to the NSClient daemon. If you are truly just running check_nrpe against that IP and port with nothing else attached to that command you should not receive this. Also, what version of windows?

In the [NRPE] section of the nsclient config you may need to uncomment
as well as verify that the host you are connecting from is one of the following
Code: Select all
allowed_hosts=10.200.50.13,10.200.40.96
and then restart nsclient service

Is your nagios host either 10.200.50.13 or 10.200.40.96?

ok, so it seems like almost all my windows servers dont work when i try to check_nrpe so im going to try to fix this before i try the windows processes, anyone know what to do?

ok nvm i figured out what the problem was, pretty much i had two of the same services trying to run to the server since i have an old nagios and a new nagios, so i have to stop the old one for the new one to work, and now the check_nrpe works. Ok, were back on track, what is to be done next
Re: Check Windows Processes

so i did a check_nrpe with that command u told me to do earlier in the threat like so:
./check_nrpe -H 10.100.50.15 -p 5666 -c check_procs_from_file -a 2
and got this:
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

What do you see in the nsclient.log file? Can you send us this? If you do not have that file, make sure the nsc.ini file has logging set to 1, then restart the nsclient++ service.
