I also use SVN + Trac. I wrote an script to sync my config files - on multiple hosts and not just for nagios - up to the svn server via cron. It works really well and most of the time I don't need the files to be uploaded immediately after I make changes, so I do it once a day and always have the rev history. Works really well and I use it also for /etc dirs and other config directories as well. Rob - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Before you get to Nagios, you need to sniff your network and figure out what is happening on those phones and see what their traffic is doing. Use ethereal if you have it or download wireshark to see what traffic is being passed. Once you determine what the issue is you will likely have to write something - or find something already written - that will do what you need, but this sounds somewhat location specific. This is beyond nagios to help diagnose the problem, as you need to diagnose before you can monitor in this case. Also - look at your switches interface stats to determine if you have runts, retransmits etc - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

You likely need to add mod_auth_pam and mod_auth_sys_group as well to your LoadModule statements (if they are not already there). Use require_group and then setup AD groups with the people you want in them. Once that is done you will be able to authenticate using the AD groups instead of the users. You also need to make sure that winbind is working properly, which it appears to be doing if your auth is already working. You can then do something along the lines of this in your Location directive: AuthPAM_Enabled on Require group "Nagios Admins" Order Deny,Allow Deny from All Allow from 10.10.10.10 This will do two things - allow you to auth on the group through AD as well as limit your access to those on the internal subnets, or external subnets that you want to allow. This will give you a "dual" setup for authentication/access that can be as restrictive or open as you deem proper for your environment. We currently do this for any of our servers that need authenticated access and it works flawlessly. Hope this helps.

This is fixed now thanks to help from Marc Powell who led me in the
right direction.
If you look at the command_line for the above notification command
you will notice that the $SERVICEACKCOMMENT does not have the
trailing $ for the variable. Because of this - the email for the
service notifications are not sent out - and there is also no error
associated with that problem. I added in the $ at the end of the
variable and now the service notifications are working again.
Crazy easy, but so simple to miss. Thanks again Marc!

[Nagios-users] Service Notifications not sending email
OK. So I have the following problem. I receive Host notifications
without any problem - email is working fine on the nagios monitoring
server. I am not, however receiving service notifications and cannot
figure out what the deal is. Any help would be appreciated as I
turned over every stone I can think of. I get the SERVICE
NOTIFICATIONS logged to syslog - but no email sent out. The
notifications are set to on, the timeperiods are correct and the
contacts and contactgroups are setup properly.
I have changed every possible parameter - except of course the right
one - and still no go.
I am running Nagios 2.9 and my configs follow.
Below are all pertinent configs. I am sure it is completely simple
and I am missing something completely obvious.
