System locks up at “Bringing up interface eth0”

jhainey · 03-31-2002, 07:00 AM

Hello

I have installed Red Hat 7.2 and everything was fine. I then changed the Mac address of eth0 and now the system will not boot. The boot process will go until “Bringing up interface eth0”.

How do I get around this so that I can make changes to the config?

Is there a function key or boot option that I can use to skip the mount of eth0?

Do I need to reload the OS?

Thanks for any help.

Do you have the 7.2 CD's? or rescue disk?

yeah first off, best to use a rescue disk or the cd's to boot into rescue mode.

my question is, how in the hell did you change the mac address ? isn't that hard coded into the device ? if you did somehow manage to mixmatch it from the system config to the device.. yeah, that is a good way to screw up your machine to lock it up.

You can change the MAC address through software even though it comes preset by the factory. Not sure why you'd want to do such a thing though unless for some strange security reasons.

I have a cable modem and my ISP limits me to 1 PC by the MAC address. I changed the MAC address on the Linux PC to test if I could use it on the internet without moving the NIC from my Windows PC to the Linux PC.

If I boot from the install CD it looks like I will need to probe the NIC for its MAC address. Any thoughts on how I would do this?

i don't know what mac address is..

however, when i configured nic card wrong..
boot process hangs at the "bringing up eth0"
but after 2-3mins it goes on..
so u can try to wait, and fix it..

what isp do you go with. some only make it so you have to reset the modem then attach to your new device to reprovision the mac address its connected to...
