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.

Lately my Debian machine (Thinkpad T22) is getting barraged with TCP Keep-Alive packets from my LInksys router, at a constant rate of around 15 packets/sec. Each packet is 60 bytes. I'm having trouble figuring out whether the culprit is my Linux machine or router. I have a few other pc's running XP on my network and they're problem free. I tried upgrading the router's firmware but that didn't help.
Can anybody suggest how to determine where the problem is?
Here's a sample packet I sniffed with ethereal. Every packet looks like this one (except for time, seq num, etc.):
Right ... that mac and ip belong to my Linksys router. I know that's where the packets are coming from, but I'm trying to figure out why. I would just conclude that the router is malfunctioning, but it's odd that only my Linux box is getting flooded and not the other pc's on my local network.
Could there be something in my Linux machine's network configuration (or otherwise) which is soliciting this flood of packets?
