Hello, I'm running nagios 3.2 under centos 5.9 and I notice if I try to issue any command such as rescheduling a check I see the message: <div class="errorMessage">"Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update! </div> <div class="errorDescription">The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions. </div> <div class="errorMessage">An error occurred while attempting to commit your command for processing. Return from whence you came" These are the permissions and ownership on this file: prw-rw---- 1 nagios nagios 0 Mar 16 08:01 /usr/local/nagios/var/rw/nagios.cmd Since this file gets recreated I tried applying the following commands: [root@cloud:~] #chown nagios.nagios /usr/local/nagios/var/rw [root@cloud:~] #chmod g+rwx /usr/local/nagios/var/rw [root@cloud:~] #chmod g+s /usr/local/nagios/var/rw This seems to have no effect. I notice if I try to reschedule the command again I get the same error message telling me to 'return from whence I came'. The only thing I can do to make this temporarily work from the interface is to change mode on that command file to world which is obviously not what you want to do. Can someone please point me in the right direction here as to where I may be going wrong? Thanks!
