@Home and DHCP

Hello fellow tux-ites,

To my knowledge Comcast at Home authenticates by machine name.  I was told
there are no static IP's, however, they must have machine names mapped
to IP's somewhere, because I have always gotten the same IP, no matter
what, Win or Lin, in over a year.

So, that said, this is how I make it work.  Set the hostname to whatever
Comcast gave you, i.e., aa######-a  (cb987654-a, for example.)  I don't
set any other parameters, DNS, etc.  I do enable DHCP for eth0.

You need to hack /sbin/ifup to make this work also.

In RH 6.x, you need to change the following line in /sbin/ifup

	if /sbin/pump -i $DEVICE; then

Change to:

	if /sbin/pump -i $DEVICE -h aa######-a; then

Where: aa######-a = your hostname (cb987654-a, for example.)

/sbin/ifup changed alot in RH 7.x and I haven't figured out the hack for
that yet.  In 7.x eth0 init fails @ boot up, but after logging in I
issue  "/sbin/pump -h aa######-a -i eth0"  and I authenticate to @Home
fine, and get the same IP every time.  If anyone figures out the hack
for /sbin/ifup in RH 7.x, PLEASE let me know, as logging into root and
using pump every time I boot into Linux gets old.

HTH & TIA,
Eric
