I obtain a different result slightly:

sparky:/usr/local/nagios/var# ps -eo pid,user,rgroup,command | grep nagios
16830 nagios   nagcmd   /usr/local/nagios/bin/nagios -d 
/usr/local/nagios/etc/nagios.cfg
16831 nagios   nagcmd   /usr/local/nagios/bin/nagios -d 
/usr/local/nagios/etc/nagios.cfg
16832 nagios   nagcmd   /usr/local/nagios/bin/nagios -d 
/usr/local/nagios/etc/nagios.cfg

sparky:/usr/local/nagios/var# ll status.dat
-rw-rw-r-- 1 nagios nagios 286639 2008-05-26 11:08 status.dat

sparky:/usr/local/nagios/var/rw# ll nagios.cmd
prw-rw 1 nagios nagios 0 2008-05-26 10:58 nagios.cmd

Thanks for your reply.

Regards,
Daniel

Interesting... smells buglish.

# grep nagios_group nagios.cfg
nagios_group=nagios

# ps -eo pid,user,rgroup,command | grep nagios

27347 nagios   nagios /usr/local/nagios/bin/nagios -d
/usr/local/nagios/etc/nagios.cfg

# vi nagios.cfg

# grep nagios_group nagios.cfg
nagios_group=nagcmd

# /etc/init.d/nagios restart
Running configuration check...done
Stopping network monitor: nagios
Waiting for nagios to exit . . done.
Starting network monitor: nagios

# ps -eo pid,user,rgroup,command | grep nagios

32016 nagios   nagcmd /usr/local/nagios/bin/nagios -d
/usr/local/nagios/etc/nagios.cfg

I see the change here -
-rw-rw-r--1 nagios   nagcmd 829161 May 22 07:25 status.dat

But not here -
prw-rw1 nagios   nagios  0 May 22 07:26 nagios.cmd

I also see that in base/nagios.c that nagios drops privs to nagios_user
and nagios_group before calling open_command_file (which doesn't seem to
specify a specific group) so I would expect it to be group nagcmd.
Clearly I'm missing something. It's unintuitive behavior at the least
but it seems more than that IMHO. Can anyone test with a 3.x install?
