"Building Secure Servers with Linux" by Michael Bauer (O'Reilly) will answer
all your server questions in depth.

"Real World Linux Security" by Bob Toxen (Prentice Hall) is excellent for
security issues.

"Linux Administration Handbook" by Nemeth et al (Prentice Hall) is also a
good all-round guide.

"Linux Firewalls" by Bob Ziegler (New Riders) has more than you'll ever need
regarding firewalls.
