O'Reilly's original Linux Server Hacks gave sysadmins 100 indispensable timesavers, tips, and solutions. This new Volume 2 offers 100 more: all of them elegant, fun, well tested, and extremely useful.

To begin, there's a full chapter on authentication in heterogeneous environments, a favorite topic of coauthor Bill von Hagen. You'll also find up-to-date collections of tips on remote connectivity, system services, storage management, security, troubleshooting, performance optimization, monitoring, system rescue, and more.

A few of our favorites: recognizing emerging problems in logfiles; booting crippled systems for diagnosis; cutting down on restore requests; using script to train junior admins; integrating Windows printing with CUPS; synchronizing multiple servers' root environments; using journaling to accelerate restarts; using your laptop as a makeshift console. That's just a taste. Your favorites may vary, but rest assured, you'll find plenty of them.
