Comcast @home connection problem ...

munisp · 01-23-2002, 12:10 PM

Comcast @home just upgraded its systems 02/22/02. After which my connection to the internet has been disconnected. I was using static ip address prior to the upgrade, but I understand the entire system is using dhcp. I have tried using "/sbin/dhcpcd -h cpXXXXX-b eth0" but have not been successful. Has any experience the same problems.? If yes, how did you solve your problem.

thanks

which distribution are you using?
do you get any error messages? or is there just an internet connection missing?

Redhat 7.2. The problem as I understand it is comcast is blocking its network from NAT.

Although Comcast says it is "cracking down" on NAT (in an effort to squeeze more cash out of their users), I don't they actually have anything in place (yet) which can actively identify and block NAT usage. Your problem is more likely related to their move to DHCP, which seems to have been less than elegant, judging from user complaints.
Try a Google search using the keywords Comcast, NAT, and DHCP; you'll see what I mean, and you might find some fixes for the problems you're having with your connectivity.

I use a linksys router with comcast@home and had to get my new ip by dhcp, but once i had the info i needed, i put it back in static, and have had no probs since i did that. You may be able to get your new ip by doing a nslookup on your comcast host name.

I just did mine and yes they have changed computer hostnames from the cg***-a format to a weired format, I'll have to call them later and find out if I have to use the new one.

heres a link to a nslooup engine. http://www.bankes.com/nslookup.htm

Well if you do a lookup on your old @home hostname you will get your old info. I just got off the phone with TS and they said that you dont have to put a specific hostname in anymore to get it to work correctlly, they are using the MAC address of the cable modem now for authintication. So my idea of trying to do a lookup on your hostname wont work, sorry. try /sbin/dhcpcd without the hostname option.

tried /sbin/dhcpcd eth0. I get an ip address but still not a connection to internet. After restart my machine, I get a very funny domain name pcp0010202xxx. In my area, comcast in my only choice of some decent connection to the net so really do not have another choice.

thanks
