In a few short years, the Linux operating system has gone from a hobbyist’s power tool to a highly usable, mainstream choice. The most popular version of Linux these days is called Ubuntu. Ubuntu’s rise to power has been rapid, historic and well-deserved. It’s the best Linux distribution ever, still most people only use a fraction of its power.
The convenience and reliability that monitoring programs offer system administrators is astounding. Whether at home, commuting, or on vacation, admins can continuously monitor their networks, learning of issues long before they become catastrophes.
Nagios, the most popular open source solution for system and network monitoring, is extremely robust, but it’s also intensely complex.
Mac OS X is the successor to the original Mac OS, which had been Apple’s primary operating system since 1984. Unlike its predecessors, Mac OS X is a Unix-based operating system built on technology that had been developed at NeXT through the second half of the 1980s until Apple purchased the company in early 1996.

Debugging, the demanding process of finding and fixing programming errors, is fundamental to successful software development. But even many experienced programmers find debugging a challenge.
The Art of Debugging with GDB, DDD, and Eclipse from No Starch Press teaches readers how to effectively use the three most popular open source debugging tools: GDB, DDD, and Eclipse.
The guides are designed to give instructions and recommendations for securing Mac OS X and for maintaining a ultra secure computer system.
Linux networking cookbook is a book for a seasoned Linux network administrator. The book attempts to describe day-to-day networking administration, maintenance and advanced issues commonly faced by us. Book covers wild verity of topics or so called recipes for Linux networking such as:
=> Building Custom Gateways using Soekris 4521 embedded board
=> Linux Firewall
=> Linux based wireless access point
=> Building a VoIP servr with Asterisk
=> Linux Routing
=> Secure remote administration with OpenSSH
=> Setting up VPNs with OpenVPN and PPTP VPN server
=> Linux IPv6 Configurations
=> Single sign-on with Samba for nixed Linux/Windows LANs
=> Setting up centralized network directory with OpenLDAP
=> Network Monitoring with Nagios
=> Network Monitoring with MRTG
=> Setting up Linux Dial up server
=> Setting up central Linux network installation server for on demand os reload and much more
I must say Carla has done an astonishing work to put together Linux networking cookbook.
This is not your Linux networking from scratch guide. Linux networking cookbook is a task-oriented book intended to offer solutions to the daily Linux networking problems and goals the Linux networking admin faces. You may be aware of that Linux networking is a complex subject. So if you need one central reference book along with examples, this book is a must for you. Each small how to (read as recipe) comes with a nice example and sample configuration / commands to carry out a task. I’m sure this book will save your precious time and energy.
Sure you will find most of the information mentioned in this book throughout mailing lists, forums, blogs, and discussion groups but not in one handy guide. Overall, a great book that touches all important Linux networking aspects. This book is highly recommended to all Linux networking admins / MCSEs / RHCEs / UNIX admins:
+ Easy of use – Gain new skills
+ Time saving tips
+ Enhance your knowledge
+ Practical advice with tons of working examples

FreeBSD is one of the fastest, secure and widely UNIX-like operating system. Some of the biggest internet sites on earth powered by FreeBSD like Yahoo. I’ve been using FreeBSD in production environments since 1998. People often ask me about FreeBSD books. So the main aim of this post is to document all free resources, books and recommended books.

Books from O’reilly and other publishers
Nothing beats well written books. Following are my personal recommendation:
- Building an Internet Server with FreeBSD 6 : “Building an Internet Server with FreeBSD 6” is the ultimate resource on the installation and configuration of open source server software with FreeBSD 6. This book contains step-by-step guides on building some of the most popular and powerful server applications available. To name a few: Apache HTTP (webserver), Courier-IMAP (IMAP server), CUPS (print server), BIND (DNS server), MySQL (database server), Postfix (mail server), and more. This book is an essential resource for new and experienced users deploying Internet servers with FreeBSD.
- Absolute BSD : Your guide to FreeBSD,the powerful, flexible, and cost-effective UNIX-based operating system. Includes coverage of installation, networking, add-on software, security, network services, system performance, kernel tweaking, file systems, SCSI & RAID configurations, SMP, upgrading, monitoring, crash debugging, BSD in the office, and emulating other OSs. Michael Lucas is a FreeBSD committer.
- BSD Hacks : Looking for a unique set of practical tips, tricks, and tools for administrators and power users of BSD systems? From hacks to customize the user environment to networking, securing the system, and optimization, BSD Hacks takes a creative approach to saving time and accomplishing more with fewer resources. If you want more than the average BSD user–to explore and experiment, unearth shortcuts, create useful tools–this book is a must-have.
- Mastering FreeBSD and OpenBSD Security : Mastering FreeBSD and OpenBSD Security is the only book currently on the market devoted completely to BSD security. Dozens of practical examples help administrators of all stripes select, configure, and deploy these operating systems. By describing security solutions for real-life scenarios, this convenient guide lets administrators push their server’s security to the next level.
Hopefully, with these resources you will be able to master FreeBSD. If you know any other good resources or books, please add them in comments!
