I haven’t had much time to look into this, but one of the mailservers I administer is typically configured to relay through mail.lig.bellsouth.net, with mail.averyjparker.com as a fallback. Sometime overnight, mail.averyjparker.com started getting heavy use and on checking this morning was getting all of the outbound traffic. So, I did a bit of investigation mail.lig.bellsouth.net […]

There are a lot of elements to a good disaster recovery strategy…. knowing where offsite backups are located, keeping the offsite backups fresh. Knowing where any ON-site backups are.

I know many people get intimidated with a black screen, white text and blinking cursor. No mouse, not knowing where to start…. well, I’m going to spend a bit of time in this article trying to help show you how to survive the command line in linux. For starters, don’t think that linux is a […]

The 2006 Winter Olympics are coming up. This time around, the olympics are being held in Turin, Italy. The official site can be found here.
