RE: DHCP and Adelphia Cablemodem (dhcpcd)
I'm responding to everyone in one message. The cablemodem setup still isn't
working. Commenting on each part individually:

Unforutnately, the NIC works fine-- I replaced the cablemodem with a hub and
checked. This seems to have something to do with dhcpcd-- when I switched
back to a static IP address, this symptom persisted. I had to remove the
package to get eth0 back.

I tried this out-- I went back to a fixed IP address, removed DHCP, and it
worked-- for a few hours. So I powered down the modem and brought it back
up-- it worked for another couple hours before quitting again. I haven't the
slightest idea how to debug this, or what coudl cause it.
On another note, I seem to be having speed problems on this machine through
the cablemodem. I was getting blazing speeds when the win98 box was hooked
up to it, but now it is much slower. Much, much slower. The differences are:
New machine, linux instead of windows, and a different cable connection
(different location in house). Any idea on how to test where the bottleneck
is?
Thanks,
Mike
