Did you know that buy default majordomo will give a list of all the addresses on your mailing list to anyone?

• Only shows lists you are subscribed to with the 'lists' command
• Does not allow anyone to use the 'who' command to get addresses
• Doesn't allow anyone to use the 'which' command to get addresses

In the same vein my last post, here is page on installing chkrootkit and Rootkit Hunter on CentOS / BlueQuartz. 

A root kit is the name given to a piece of software written to try and elevate someones permissions to root level, commonly used by hackers/crackers/script kiddies to infect a system. There are many rootkit checkers however we are going to install two of the most common which are both are free and open source.  Some people prefer one over the other, I say, why not use both!

After just rebuilding a BlueQuartz box I thought I would copy my install notes. This is an entirely personal list of things that I do to a vanilla install of CentOS/BlueQuartz.  I thought it may be useful to other people.
