Though it might seem exactly like other books of the type, this book is not only very logically arranged, with topics from the basics to most things any admin just needs to know, from single user system config to a server governing the network and users. It also manages to get even a novice from the level of "how to click something out", through where to click and why, to how to do it with a set of simple basic commands. These commands are described in enough detail for the readers, whatever their level of system proficiency, to understand them and their functions. The troubleshooting commands featured in the book are rather straightforward, so any proper admin would only need the book to recall the syntax with optional arguments. Most important log files are also described, though they are not all present in a single chapter, rather the basic system ones in one with others in the respective others. Book is focusing on RPM-based systems (Fedora to be exact), it's quite a refresh after all those debian/*buntu ones. Especially since also Cisco managed network solutions with *nix base are described from the side of linux on those machines. Majority of the book takes care of the network sharing (basically samba/nfs) with interesting troubleshooting and repair part on the firewall actions incl. vpn preparation. Finally, the more advanced part gets into grips with the topics of server preparation, dns, web server setup with mysql, ftp and ssh, and most advanced part on server performance monitoring. The book ends with the topic of server preparation with disk quotas, centralised logins and security technologies/protocols (incl. LDAP and RADIUS) usage on linux servers. Finally, there's an introduction to kernel prepping for performance.
