Connect laptop to desktop through network card and DHCP

Hi,

I can't seem to find a solution to my dilemma, so don't know if it's actually possible. I recently got a laptop(running Kubuntu Feisty) and what I want to do is connect it to my desktop PC (running openSUSE 10.1). The desktop has one network card sitting at eth0.

What I wanted to do was get a dhcp server running on the desktop listening on eth0 (openSUSE's dhcp setup didn't seem to work for me). After *much* mucking about I got dhcpd to listen on eth0 by running

Code:

dhcpd eth0

My dhcpd.conf file is pretty bare bones, it has the following:

Code:

ddns-update-style ad-hoc;

subnet 10.0.0.0 netmask 255.255.255.0 {
  range 10.0.0.3 10.0.0.20;
  option broadcast-address 10.0.0.255;
}

When I connect the two with a network cable, nothing happens. What am I doing wrong? (the laptop connects to other dhcp servers, so I don't think there is a problem on the laptop side)

Well for starters if you are just connecting a regular network patch cable between the two pc's it will never work because you need to use a crossover cable to allow duplex communication.

If you are using a crossover check to make sure that there are link lights on with both of the pc's

If you have no idea what a crossover cable is then go buy a cheap network switch or hub and use that instead.

If you are certain you have the cabling topology right then make sure you have the correct drivers and modules loaded for your network cards on both the systems as well as the dhcpd processes

Ah! That'll be it then. It's a regular network cable. I'll hunt down a crossover cable then.

Thanks, I'll give it a try
