About

“One of the best technical writers in the networking and security environments.” – Midwest Book Review

I’ve been publishing books since the early 1990s. This site covers my nonfiction work. I have a separate site for my novels and stories and, if you’re deeply bored, a site about me.

I’m currently writing a third edition of Absolute FreeBSD–now on preorder. If you want to know the current status, search Twitter for #af3e.

My newest nonfiction includes SSH Mastery, 2nd edition, Networking for Systems Administrators, FreeBSD Mastery: Storage Essentials, Sudo Mastery, and Absolute OpenBSD, 2nd Edition. You also need my earlier books, like DNSSec Mastery and Network Flow Analysis.

I live by Detroit, am happily married, practice martial arts, and have pet rats.

Questions? Check my FAQ. Or read the autobiography pages, where I surrender my dignity. Repeatedly. Fortunately, dignity is a renewable resource.

I update this page after book releases. Want updates? Check my blog. Want really frequent and trivial updates? Check Twitter. Or look at my contact page.
