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.

First, I am definately a newbie with very little experience working with Linux.
Info: Dell PowerEdge 1950
Redhat Linux Enterprise Taroon Update 8 (RHEL 3) 2.4.21-50
Two NIC Cards
This machine runs our webportal, so it is imporant for us to keep it up. We had to reboot the machine the other day...and of course, it seems that many of the settings were lost went it came back up. We have two nic cards installed in the machine, but we are only using eth0 (eth1 is not active). We can get to the web page just fine externally, and we can putty to the machine internally. It does seem that after about 30 minutes or so of no system activity, the eth0 some how dies and the web portal goes down externally and of course, I cannot putty to it internally. At this point, we have been inactivating the eth0 and then activating it again, and this opens the connection again.
Does anyone on this expert group have any ideas or pointers as to what we could do or review to rememdy this issue? We are primarily a Windows shop except for a couple linux boxes we ended up with (yes....don't laugh too loud). Thank you very much in advance.
Yes, it actually just happened again, just about 30 minutes after my last interaction with the sever (via the website). We can get on the terminal and the system runs, but for some reason the nic card just stops (from what we can tell, since we can no longer connect externally or internally to the machine). We are really at a loss as to what should be reviewed.
