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.

As of yesterday, my computer was running fine wired to a D-Link DIR-635 router, through which I connect to the internet. Now it seems that at some point overnight my ethernet connection has decided to totally stop working, for no apparent reason. The weirdest thing is that neither the computer nor the router have been turned off at all, it's literally just stopped.
There are lights on on both the PC and router, indicating that there is a connection, but now I can't connect to or even ping the router from the PC at all. I've bought a brand new cable, but no luck still. The other computers in the house work over the wireless, which isn't really an option because mine is too far away to get a good signal. There's also an Xbox which connects fine when wired to to the router. I've tried using both ethernet ports on my PC and on the router.
Is there anything else I ought to check? Or has anyone got any idea what's wrong?
what do you get for outputs for lspci, lsmod, ifconfig, what does your /etc/network file look like, did you do any software upgrade to the system, particularly kernel? What type of error do you receive when trying to connect, if any? Are you using DHCP, static IP, static/reserved dhcp, did you try using the opposite if what you were using i.e. if you had been using DHCP did you try assigning a static IP? These would be some good questions to answer as a start to get better assistance. I;ll be keeping an eye out to see if I can help you.
Hi, thanks very much for the reply. To answer your questions:
> Yes, I have tried both DHCP and statically setting the IP address.
> Upon issuing an 'ifup eth0', I get the message 'Determining IP information for eth0... failed' when using DHCP, and no error message at all when using a statically set IP. It seems that the interface is actually brought up fine, but then just can't see the router.
Below are the outputs you requested.
Thanks for your help.
