[PLUG] Networking problem. (warning, newbie alert)

Thu Sep 29 22:40:18 WST 2005

Hiya all...

I'm using Ubuntu Breezy and am having a whole stack of problems getting my
network to run. I have a Windows box and my gateway, connected to a ISDN. I
have a 8 port switch and 2 NIC's in my linux box.

I have got the network cable plugged into eth0.

I have done some searching on the net and came up with a variety of commands
that give me a whole heap of information, but I know nothing about how it
interpret it.

Here is the output from these commands that I found:

After that I rebooted my linux box and now I can't access the network
anymore. I have no idea what I am doing now.

I am sure that my gateway is 192.168.0.1 <http://192.168.0.1> - that's the
xp box - so why is "DHCPDISCOVER on eth0" to
"255.255.255.255<http://255.255.255.255>"?
Have I not set the gateway somewhere?

I don't know what to do.

Thanks in advance for any help.
