do you have a router? are you doing static IP? Lets start there and assume you are.

Under System manager you can set up your network, lets just for giggles says your home router's IP is 192.168.1.1, lets say you set up your SGI's IP to be 192.168.1.10 (also about the netmask -> 0xffffff00 == 255.255.255.0 == ff.ff.ff.0)

Your first step would be to see if you can ping your router:

ping 192.168.1.1

if that works, try to ping something outside your network, like googles public DNS:

ping 8.8.8.8

Let us know if you got this far
