FW: [Gllug] Networking SUSE and Windows

[Tom Trainer]

Yes, I am running ICS on the Windows machine.  How do I set up DHCP on
the Linux machine?

A few observations:

The traceroute in SuSE uses the -I flag for a different thing than some
others - it specifies an interface to trace over not to use ICMP instead
of UDP. So your "-In" fails because there is no interface called "n".
AFAIK there is no way to use ICMP with SuSE's traceroute which is a pity
as it is often useful when dealing with recalcitrant firewalls.

It's /etc/resolv.conf not .config.

To view a file's content you do not just type its name, that means you
want to execute it which makes no sense with /etc/hosts. Use "cat" or
"view".

You havn't said much about your basic setup. Is this Windows machine
running ICS?
If so I believe that you have to set the Linux machine up as DHCP, have
you done so?
