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 have the identical setup with comcast and it works fine. There's something wrong with your network configuration. Post your /etc/modprobe.conf and /etc/sysconfig/network-scripts/ifcfg-eth0 and we can compare these and any other files you might want to see.

I forgot to mention that I live in Lansing, Michigan....

/etc/modprobe.conf
------------
alias eth1 tulip
alias eth0 8139too
alias sound-slot-0 snd-emu10k1
install snd-emu10k1 /sbin/modprobe --first-time --ignore-install snd-emu10k1 && { /sbin/modprobe snd-pcm-oss; /bintrue; }
install usb-interface /sbin/modprobe usb-uhci; /bin/true
remove snd-emu10k1 { /sbin/modprobe -r snd-pcm-oss; }; /sbin/modprobe -r --first-time --ignore-remove snd-emu10k1

/etc/sysconfig/network-scripts/ifcfg-eth0
----------------
DEVICE = eth0
BOOTPROTO = dhcp
ONBOOT = yes
MII_NOT_SUPPORTED = no
WIRELESS_ENC_KEY = ""



please help

You have two nic interfaces loading(eth0 and eth1). If you don't have two nics in the box, the first thing I would try is removing both from Mandrake Control Center>Network & Internet>Remove a Connection and trying to reconfigure your network under "New Connection". After you do the removal, make sure the references to eth0 and eth1 are gone from modprobe.conf and that ifcfg-eth0 and ifcfg-eth1 have been deleted.
I've had problems in the past trying to configure two nics in mcc and have usually had to do everything by hand. Also, swapping nics in and out seems to confuse the heck out of mcc. I'm trying to get you back to square one and see if the mcc network utilities will work.

Got it fixed

I just had to unplug the cable modem for like 30 seconds, then I plugged it into my box so that the modem looked for the new NIC and it worked

Thanks man
