[ale] Problem with using dhcp and cable modem

[Joe Knapka]

DHCP should be setting the IP address for the card connected to the
cable modem, but not the one on the lan. So you could add an entry
to the C:\windows\hosts file on each of the Win98 machines
that looks like

<Linux-box-non-dhcp-address>	bandit

and a similar entry in /etc/hosts on the Linux box. On a small
network like yours, using hard-coded host names isn't too
onerous. Alternatively, you could run a DNS server on the
Linux machine to resolve local names, but I don't know
how to set that up; maybe someone else on the list has
some advice.

Good luck,
