Error: Could not open command file '/var/log/nagios/rw/nagios.cmd' for update!
The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions.

I checked the permissions in the directories starting from /var on down to nagios.cmd and everything is as it should be according to the documentation. I found online a tip to make sure the user apache runs as is a member of the nagiocmd group. So I used gpasswd -a apache nagiocmd to add the user to the group. now when I do a cat /etc/group I see this:
It still does not work ( also added the nagios user just to try it). What does the "!" mean in this context? This is the only group that has the symbol and I have not seen this before. I'm down right confused. Thanks for any help.
