Error: Could not open command file

[GaWd]

I've installed Nagios several times, and this has always worked for me. I installed a fresh install on a new CentOS 5.x computer, and I have been unable to get the permissions to allow proper updating through the web interface. I've checked the /usr/local/nagios/rw permissions many times and have been unable to get any movement.

Not-working installation:

[root@localhost etc]# ls -lh /usr/local/nagios/var/

drwxrwsr-x 2 nagios nagcmd 4.0K Oct 16 09:13 rw

cmd file:

prw-rw---- 1 nagios nagcmd 0 Oct 16 09:13 nagios.cmd


Working installation:
[root@mvnagios ~]# ls -lh /usr/local/nagios/var/

drwxrwsr-x 2 nagios nagcmd 4.0K Oct 10 06:41 rw

Here's the cmd file:

prw-rw---- 1 nagios nagcmd 0 Oct 16 09:15 nagios.cmd


Any ideas?

Fixed by using Giuseppe's PDF for core installations-

usermod -G nagcmd apache
