Install mod_security 2 on CentOS/RedHat

This is a translation from Spanish to English, but still the best guide I’ve used so far. Modified slightly to help others but could use more work.

Important: ModSecurity blocks lots of UNIX commands. I had to add dots to them. They are colored red so you know to change them.

This article assumes that you have installed a RedHat Enterprise or CentOS and not guaranteed to work, although we have tested on several CentOS 4.5 with success. (more…)

ListMessenger SMTP Error

I started receiving the following error after making some network changes:

How I fixed it: I set my ListMessenger to use PHPmail and then edited my php.ini file. In that file there is a setting for your smtp server, it was set to localhost. I changed it to our default smtp server and it worked again.

Why: I was fiddling around with network settings and managed to break something so that computers on the local network can’t access the server via it’s name, and apparently it can’t access itself by localhost. I’m not sure why this happened but I think it has something to do with VMWare network cards stealing priority and forcing IP’s that didn’t work.
