I have 2 pc's, and want to create a small local network.
Where do I start.

Purpose of this is that 1 pc has a internet connection via the tv-cable, and I want the other pc to go tot the internet via the first.

Any help to get me started would be welcome!

I prefer using a router like the Linksys BEFSR41. This connects to the cable modem and has several RJ-45 ports for your PCs to connect to. This has the advantage of no special setup on either PC (to act as a router), and very simple but secure packet filtering to protect you from the internet. Then assuming both PCs have NICs, your actual network configuration details will vary somewhat based on your Linux distro.

I think you might find it cheaper and easier to use a hub and set your winBox as a router or use a proxy connection.

The Hardware you would need would be cat5e ethernet cable to go between the comps and the hub, ehternet cards for both boxes unless you already had them (many new comps come with them. They look like big phone jacks.), and a network hub.

Then the layout is:

tv-cable eth eth
ISP------------ WinBox (acting as router) ----- HUB ----- Linux

Linux and win can talk, ISP and win can still talk, and Linux can now talk to the ISP through the win.

This idea is basically the same as the previous poster's, except that I think that on a network of yours' size, you don't need a physical router; the winBox should be able to do it with software.

Got things working! Got a good HOWTO from the SuSE support site, with this things suddenly are a lot less complicated than they seemd to be.
