Re: LINUX SUPPORT FOR CABLE-MODEMS?

[Ron Welch <welch@cs.lmco.com>]

I am fortunate enough recently become a subscriber to Time-Warner's
RoadRunner Cable modem service. I have not actually gotten around
to setting things up to work with Linux yet, but I have been looking
into what it would take to do it, and here is what I believe to be
true so far.

RoadRunner, in my area at least, uses DHCP to assign IP addresses.
So, while the chances are quite good that the address assigned
to you me remain fairly constant there is no, garauntee that it will
be completley static due to DHCP's lease times. At any rate, DHCP
client support will be need under Linux to get an IP address
dynamically assigned.

My RoadRunner service also uses Kerberos for authentication. So
Kerberos support in Linux is needed for negotiation of passwords
and such.

I believe both of these peices to the puzzle exist under Debian.
Please correct me if I am wong. As soon as I get some "spare" time
get my cable modem to work under Linux because even under Windoze,
it is **FAST**

Hope this helps...
