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.

To give an overview of how my home LAN is setup, here is a diagram (it may not be of any significance
PC2 Wifi AP PC3 Printserver
| | | |
Internet <--> [ADSL Router] <---> [D-Link Switch]
The printserver is a Intel Netport Express 10/100, with 2 x parallel ports and 1 x serial port. It has been functioning fine until recently, where when it is plugged into the switch, it blocks all traffic from the switch to the rest of the nework, for anything. When the printserver is not plugged into the LAN then everything works fine.
I am not sure why it would do this... Does anyone have any ideas?
Actually I don't think the switch has an IP. Usually they are pretty dumb pieces of hardware. I was suggeting that the print server had the same IP as another device on the network like the router or another computer. If everything is running on DHCP then a conflict is unlikely, but if you are mixing DHCP with static IP then there might be a problem. I'd still check into what devices have what IP.
Are there any "special" ports on the switch? What I'm getting at is are there any ports that are designed for specific tasks like connecting to the router or might need a crossover cable. Usually they don't, but it might be worth a look in the manual.
The other thing to try might be to listen to your network traffic with something like ethereal. I'd do it with the printer server unattached to get a baseline of what kind of traffic is normal and then plug in the print server and see if anything changes.
Needless to say I don't have any real explanations for what your are seeing, I'm just suggesting some ways to try and figure out what is happening.
