Roadrunner on Redhat 9.0 wont work


I have a roadrunner cable connection for windows xp. It works fine on xp. I have a seperate machine running redhat 9.0 that I would like to be able to access the internet with at high speed, using roadrunner. I typed IPCONFIG in windows to get ip address, subnetmask, gateway and dns info etc. I tried to plug this info into network configuration on redhat. eth0 status is active, I tried to statically set the ip addresses and the rest of the info and I also tried to automatically obtain ip address settings with DHCP, both failed. does anyone have any sugestions for this linux newbie?

thank you.

Try resetting your modem, the modem and RoadRunner will usualy cache the mac address of the NIC it was last connected to, when swapping out, you have to reset the modem by unplugging the power for about 30 seconds.

Then set your network config to DHCP in Redhat to obtain an IP address.

Cheers.

I assume that you are using a hub or a switch to connect the two PCs to the modem and not a router. I would guess that Roadrunner only provides one IP address (i.e. without paying extra). The modem keeps the MAC address of the NIC in memory and will not assign an IP it it isn't the same.

To test the theory with the windows PC disconnected or shutdown cycle power on the modem. Next, try to obtain an IP using DHCP on the RH box.

I haven't tried this myself but you could try to assign the RH box NIC the same MAC address as your windows box.

# /sbin/ifconfig eth0 down
# /sbin/ifconfig eth0 hw ether 00:00:00:00:00:00
# /sbin/ifconfig eth0 up

Replace the 00:00:00:00:00:00 with the MAC address of the other card.

Other solutions:

Configure the linux PC as a router for the windows PC. This would require installing a second NIC in the linux PC.

Obtaining a hardware router such as D-Link or Linksys.

I knew working at TimeWarner doing cable modem support would pay off one day on LQ.org..

Glad that worked for you.

Cheers.
