Nagios Support Forum

Hello,

I am trying to setup passive checks between Windows machines to Nagios XI using NSCA protocol. The config is almost done, but a have this error message at "nscp test" screen :

{{{

At the server side this is the situation:

Jul 13 23:07:55 localhost xinetd[16203]: START: nsca pid=16709 from=::ffff:79.106.109.190
Jul 13 23:07:55 localhost xinetd[16709]: FAIL: nsca address from=::ffff:79.106.109.190
Jul 13 23:07:55 localhost xinetd[16203]: EXIT: nsca status=0 pid=16709 duration=0(sec)

I checked the password, encryption, firewall. All are OK!
What should I check first?
Thanks!

Can you share your nsclient.log file with us? It should be located in the nsclient base directory. If there is sensetive information in there, just send us a snippet of the log after you force a NSCA passive result.

Thanks for the reply!
Log file is here attached.

What version of NSClient++ and Nagios Xi are you using? Have you been able to run any active checks to this nsclient system or have you only tried with NSCA?

NSClient++ Ver. 04.1.90
NagiosXI Ver. 2012R2.2
I have tried only with NSCA on two PC (Windows 2003 server and XP). Same situation.

I activated and tested active checks (check_nt) right now. This works fine!
Passive checks not!

Make sure you have the windows server's IP in the "only_from" line in the "/etc/xinetd.d/nsca" on the Nagios XI server. After modifying the file, restart the daemon:
If this doesn't help, post the "nsclient.ini" file (hide the sensitive info).

Note: I am moving this topic to the General XI Support Forum, since it doesn't belong here.

The problem is solved!
I have not correctly commented out the "only_from" ligne on /etc/xinetd.d/nsca condig file.
Thanks!

Ah that would do it!
