Cable modem configuration??

Cable modem configuration??

Post by David Getso » Wed, 15 Oct 1997 04:00:00



Does any one know how to setup up a Linux box with Rogers wave?  (Please

note: Rogers does NOT use DCHP).  So far I have been able to confirm
that the routing IS correct. (We use the same IPs we used before with
WIN95!)

We are receiving a huge amount of packages from the cable modem while
the ethernet card
is connected to the cable modem, but we can not even ping the gateway
(using the IP address). We have no problem connecting to another
computer
(linux box three feet away).

Any input would be greatly appreciated.

The following is some of the configuration info:

What about your host name?  I had the worst time getting my system to work
with my cable modem (Motorola *Surfr) until I realized that my hostname
was different than the one they assigned me.  Edited /etc/hosts, and I'm
whirring along at cable modem speeds.  Something else I noticed, and it may
just be my lack of general ethernet knowledge, but I couldn't help noticing
that your broadcast address is set to a different net than your IP
address.....could that be causing a problem? Hope this helps.

1. Cable modem configuration with RH 5.1

        You need to define the ISP's gateway and set that
        as your default gateway. Whynot just use dhcp?
