I swear Comcast is making this harder than it has to be...
I search all over this forum for an answer to my prayers but alas I found none. None that worked anyway... I tried setting up a proxy to: sas.ne2.attbb.net or sas.attbi.com ... and neither worked, I even tried to share internet connection between my Windows computer and my linux computer, but that didn;t work either..

This is my specs:
Running Mandrake 10.0
Comcast with SurfBoard ethernet plugged directly into the linux box.
ethernet card (eth0)...

I know the ethernet cardworks because it worked last week when i lived in the dorms.. and i have 3 other ethernet cards, tried them all, and same problem..

i also have a windows xp machine... Comcast works with Windows, with help with the CD that they gave me... i popped in the cd and it took me through some steps asking me for customer account info and such, then it worked... then i tried to set this up with my linux box, taking the ethernet cord out of my window box and plugging it into the linux box and no matter what i try I cannot get it to work.

as Root I type:
ifconfig...

eth0 has no ip address... it IS setup for dhcp
i tried dhcp-client
dhcpcd
pump
and some other types of dhcp

dhcpcd eth0
gives me an error:
Argument not found...
dhcpcd.exe looking for a filename argument

so i did man dhcpcd
found the debug switch
did:
dhcpcd -d eth0
it printed out my MAC address
and then said the same error

Some suggested I call comcast...
So I did, I told them that all i had was linux and nothing else and i had to have it work with linux, she said that some users claim that comcast works with linux but they have no support for it and have no step by step process... i even asked her is there a proxy that i can connect to to get it to work, and she said she doesn't know and they don't have that information...

So you guys are my last help, plllleeeaassssee help

THANKS SO MUCH

I use comcast internet and I called them and they manually set up my connection (the same as setup in windows) and it works perfectly from linux

Did you try unplugging your modem for about 10 seconds and then plugging it back in after switching the ethernet cord between computers? I had to do this before we set up a wireless network.

yeah, i read this somewhere, and i tried it... still has not worked

I forgot to mention im from Lansing, MI

I used to use @Home... and then ATTBI when they took over for @Home... and now Comcast since they took over for ATTBI. I just recently did a dual boot install of Linux (my first Linux install) and had no problem with Comcast. It sounds to me that you might be using old settings though. The domain attbi.com is no longer online so trying to use an old attbi.com proxy probably isn't going to work. My only suggestion would be to set up your computer to use DHCP and nothing else (no login, no proxy, etc.) For me, those settings work for everything: Mac, Linux, Windows, PlayStation 2. Hope that helps.

I only tried those proxies because i read somewhere that i should try them... but right now im just using normal dhcp and no proxies at all and its still not working

unplug the modem for about 15 minutes, Comcast only works with one mac address... if you switch back and forth between a windows machine and the windows machine works.. the MAC address is cached for the other machine.

try unplugging the modem for 15 minutes or so... fireit back up.. and then boot up the linux machine... It should work...

good luck


Thanks

I think spaaarky21 has hit it on the head. I have been using Comcast and linux for a while now and have had no problems. I just let DHCP do it for me.

Yup You guys were right!!!!! It worked

Thanks a bunch
