Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

I took my RHCSA test today (non-official pre-test). I finished all ~20 objectives in 30 minutes, minus one objective regarding quotas. Hrmmm...can't seem to recall the quota init command (and I've never really used Linux quotas before...this may get interesting). No worries, man -k to the rescue!
man -k quota
Well, ok, there are the commands for managing quotas, checking quotas, reporting on quotas, etc...but no "set up quotas". See, when I try to run...

I was driving to the store tonight. As I drove through the (seemingly) deserted stretch of parking lot, I came up to a man, woman, and child walking through the dimly lit area. I noticed that they were uncomfortably close to the road, so I started to fade to the left to avoid them. As I approached, the man continued narrowing the gap between my 2 1/2 ton vehicle and his body. His wife wisely stayed to the right with their child...but then an amazing thing happened...

It's been nearly a year since I started working at Rackspace, so I've been thinking alot over the past few days about how my life has changed since I started this insane wild ride. Aside from the expected "I live in San Antonio now", or "I make better money now", or even "I can't begin to explain how much I've learned in the past year", there are deeper, more subtle changes that have had oddly profound effects on my day to day life.

So a while back I got my hands on a Cisco 2948 for my home network. Sure, it's only 10/100. Sure, it's an older model. Sure, it's EOL.
But damn it's sexy in my livingroom...48 ports of Cisco goodness. Port security! VLANS! So much more than my other "dumb" switches! Imagine the possibilities! I set off flipping knobs and tweaking everything as tight as I can. Months of restful sleep ensue, with my world protected by pf and a locked down switch.
