Nagios Support Forum

I have just installed Nagios 3.2.3 on Ubuntu Server 12.04LTS and using SSMTP for my email. However when the system tries to send a emain it is being sent to root@localhost which fails to be deliverable. I have it currently sending from my email address which we use Google Apps for Education so I kno...

Here is the output from my error log

I just installed nagios 4.0.1 on a fresh CentOS 6.5 32-bit system and everything went perfect until I tried to access any of the tabs on the left side of the screen.

Every one of the tabs return a internal server error.

Any suggestions???

Got it fixed!!!

I have disabled selinux for testing to see if I can get anything working...

So what is my path to correcting this problem?

I am somewhat new to linux in so much as I have worked with it for only about a year.

UPDATE:

At the urging of my CIO, I have built a completely new CentOS 6.5 VM and followed the Nagios provided install quickstart for Nagios 4.0.2

I am still getting the same problem when I go to the Nagios web interface.

UPDATE

In the server log I am finding a lot of this:

Warning: Return code of 127 for checking of service ... Make sure the plugin you're trying to run is actually exists

When I did the base install I also installed all of the plugins with no errors.

I am totally lost now...
