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.

The problem that weren't.
Sometimes even old poops like myself will get thrown off by a problem. I inherited an old desktop from my son and put Linux Ubuntu 10.10 on it, to use it as a local server. The computer did not have a wireless card, so I shoved in a Netgear 802.11b usb jobby-doo. First chance I got I found a ($3.00) 802.11g usb card and plugged it in in place of the Netgear card.
Well I noticed (emphasis on noticed) in network monitor my CPU usage was up around 30% and the throughput monitor was at 1KB with no activity. I upgraded to an 802.11n card and the same thing.
Like the good Linux-head I am I ran "top" and saw that Xorg was hogging 25-27% of the cpu. After a couple hours of reading and trying to figure out why, I plugged in the original netgear usb thingy and finally noticed it happening on it too. I had never noticed it and assumed the upgraded 802.11 devices were being hogs.
Finally I exited network monitor and sshed in from another box and ran "top" again. Xorg hog was gone. Yeppers, I was looking at load activity from the Network Monitor which was my "culprit". ROFL!! There was no problem. Never had been.
I plugged the 802.11n card in (now I have a spare 802.11b card and tewo spare 802.11g cards) and all is well. Good thing the average cost of those "spares" was $5.00. What a maroon!
