Unable to write to nagios.cmd

Nagios XI 2014R1.3 on RHEL 6

One of my users reported being unable to Acknowledge a service in the Nagios XI GUI.
I was able to reproduce the problem.

"Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update!'

Looking at the nagios.cmd file, the permissions didn't seem right:

ls -l /usr/local/nagios/var/rw
-rw-r--r-- 1 root nagcmd 420 Jul 30 13:35 nagios.cmd
srw-rw---- 1 nagios nagcmd 0 Jul 30 12:00 nagios.qh

changing nagios.cmd from 644 to 664 fixed the symptom....but I don't know the cause.

Also, restarting nagios via '/etc/init.d/nagios restart' produced the following nagios.cmd file:
prw-rw---- 1 nagios nagcmd 0 Jul 30 13:52 nagios.cmd
which looks more like what I would expect.

The ownership also looked a bit off. Here's mine:

Code: Select all

prw-rw---- 1 nagios nagcmd 0 Jul 30 11:42 /usr/local/nagios/var/rw/nagios.cmd

So yours looks correct now. Does anyone else have access to the system who may have changed the permissions? Did you have a power failure, run out of disk space, or otherwise experience any abnormal events recently?

Wow...this is old. I forgot all about this one. No clue who/why the file changed. I may have done it when working on something else. In any case it's working and we can close this thread.
Sorry about the late response!

Well, thanks for getting back to us in any case!
