One thing is that my friend uses RoadRunner as well in Binghamton, NY and he
has told me only one IP will get assigned to him at a time through the cable
modem connection. Don't know how they set it up but he only can have one
machine connecting through the cable modem at a time. I decided I would put
Linux on that machine and then create a private class c for his housemates
and let linux use IP Masqurading .. yadda yadda.. to give them all IP
access.. but even though I got the DHCP client going and seemed to get all
the info from the DHCP server I can only ping the gateway and not anything
beyond.
I'm curious what you did to make that connection work? In windows they have
some dopey software that asks for a password before your IP starts getting
beyond the gateway. I'm guessing I have to replicate whatever that program
does for linux to get going.

Subject: DHCP Problems
I am hooking up a second computer to the Time Warner roadrunner cable
modem network in Albany, NY. The first computer has been running smoothly
using RH v4.2 with dhcp at boot time. I am running v5.1 on the new computer.
At boot the ethernet card is detected properly and dhcp fires. However, it
is consistently fails. As additional information, I have somehow screwed up
the configuration such that I cannot successfully ping anything - even
localhost! When I run the network configurator under the control panel, both
localhost and eth0 are inactive - I cannot activate them. Also, an odd
observation - for v4.2 when dhcp fires it updates some network information
contained in two files (resolv.conf and hostinfo-eth0) in /etc/dhcpc. This
directory does not exist in v5.1. I went ahead and created it.
I must be doing something stupid. Anyone have any recommendations for
things to check or try out?
TIA,
Steve Ettorre
