Alright, I realize this isn't the first time this question has been asked. Read all the info, still can't get it. Any help would be much appreciated.
Setup: Two 'computers', one running embedded linux 2.6 on a mini2440 ARM development board (more info below), the other also running linux 2.6 on a desktop.
Goal: Mount the root drive on the development board to the desktop though a crossover ethernet connection.
Problem: It appears both NIC's are working (see below) yet the status lights on them don't turn on, hence pinging (let alone mounting) doesn't work.
Desktop Specification:- kernel: Linux 2.6.27.7-9-pae
- OS: OpenSuse 11.1
- Desktop: KDE 4.0
- shell: Bash

Potential Problems?
Commands ran on development board:
Code:
# lsmod
Module Size Used by
mini2440_backlight 1696 0 - Live 0xbf000000
# find / -name eth0
/proc/sys/net/ipv4/conf/eth0
/proc/sys/net/ipv4/neigh/eth0
Other Notes:- I'm sure I have a crossover ethernet cable as I've used it to create a connection between to windows computers (I've also verified the pinout).
- Fairly certain the desktop NIC works since the status lights turn-on when the crossover cable is connected between it and my windows laptop.
Please help.
