Assuming your cable modem setup is similar to my DSL one, have you taken
a look at the netmask setting for your ethernet interface? Let me
describe my setup, if yours is the same then perhaps it will help, if
not just skip it!
I have two PCs and a DSL modem. Assigned to me are 8 IP addresses
(allows for future expansion ;-); of which one is the network address
(the lowest numbered), one the broadcast (the highest numbered) and one
the DSL modem (or gateway).
The remaining five are mine for hosts... now, since I have 8 IP
addresses as opposed to the 256 that my class of IP address would
suggest, I need to tell Linux a little more about the network. I did
this using the GUI based linuxconf utility which writes to a file called
ifcfg-eth0 in /etc/sysconfig/network-scripts in my case (I'm also using
RH6.1 so this should be close to your system's workings too).
In that file, my netmask is set to 255.255.255.248. If you have only 4
IP addresses (i.e. network,broadcast,gateway and a single host) you'll
need 255.255.255.252.
Hope that helps a little...
John...
BTW Win98 should also have these settings so you could check there to
see what numbers you need if you're not sure.
