If you distilled the essence of Linux network administration into one readable, usable, not-too-gigantic book, this would be the result: Linux Network Administration Guide, Third Edition.
This book's roots trace back to some of the earliest, most widely-used Linux networking documentation. But it's been massively revised in this edition, with new or thoroughly updated coverage of wireless networking, OpenLDAP, security (from OpenSSH to Spam filtering), IPv6, and plenty more.
It's surprising how much the authors can teach in just 300-plus pages: how to configure TCP/IP networking, name services, PPP, firewalls, IP accounting, NAT, sendmail, Apache, IMAP, Samba, BIND, and many other key technologies and services. No single book can cover the entire discipline of network administration. But when you've got a question, problem, or challenge, this example-rich guide is the place to turn.
