hrm, i have directions i was given to network my linux that i havent actually tried yet, but you can give them a shot.
1. you identify your nic, and figure out the correct module.
2. modprobe nic_modulename
3. plug the box into the hub
4. once the module is loaded, you use ifconfig to set a IP address.
5. ifconfig eth0 inet 192.168.1.1 255.255.255.0
and thats the process ive been told. hopefully its that easy haha, but i dunno, if you wanna try it good luck
