What's to say? Check my personal website for a touch more detail, if you want to. I've been a professional UNIX/network sysadmin since 1991, and currently sysadmin free software for a living through my own little company. I'm a Fellow of the European Free Software Foundation. A long time ago, I and a co-author wrote "Building Linux and OpenBSD Firewalls" (Wiley, 2000). That's it.
