Hi Brian, On my system the /usr/local/nagios/var/rw directory has permissions drwxrwsr-x. This is the only difference I can see between my system and yours. Regards, Guy. <div class="gmail_quote">On 14 July 2010 12:50, Brian O'Mahony <<a href="mailto:brian.omahony@curamsoftware.com">brian.omahony@curamsoftware.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div link="blue" vlink="purple" lang="EN-US"> <div> Error: Could not open command file '/usr/local/nagios/var/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. An error occurred while attempting to commit your command for processing. I did however recently do a restore of the machine (I restored an old copy of the VM and then copied over the backup data). When I change the permissions, next time I click commit, it goes back to being un-openable: [root@nagios servers]# ls -al /usr/local/nagios/var/r* /usr/local/nagios/var/rw: total 2 drwxr-xr-x 2 nagios nagcmd 1024 Jul 14 12:40 . drwxrwxrwx 6 nagios nagios 1024 Jul 14 12:42 .. prw-rw---- 1 nagios nagios 0 Jul 14 12:40 nagios.cmd B </div> <pre style="white-space: normal;"> The information in this email is confidential and may be legally privileged.
