Bringing up interface eth0: FAILED
 

--------------------------------------------------------------------------------
I'm getting a "Bringing up interface eth0: FAILED" error when Mandrake 8.2 is loading. I uninstalled iptables/firestarter so its not my firewall blocking DHCP info. And think its a problem with DHCP but i can't fix it. Heres my logs.

That sharing IRQ could be a problem, how can i change the IRQ for my NIC? Also heres whats in my ifcfg-eth0

Any help is appriciated.

Re: Bringing up interface eth0: FAILED
 

Everyonce in a while it will work but seems to fuck up on its own. Its getting extremely annoying. Heres a example of what will happen.

I reboot and login as root, open up konqbrowser and go to google.com and it will work. I spend like 4 seconds on loged in. I reboot and do that again to make sure it will work again. It does. I reboot to windows and play some Q3. I reboot back to linux. Its fucked up again. :/

I'm going to take a shot at answering your question and I could be way off base and if so my apologies. I'm a newbie so I'm hesitant about saying anything. But I use Roadrunner which is also cable and it doesn't a static IP address. I used to use a laptop and my desktop computer and I would have to release and renew my IP address before I could switch from one to the other because Road Runner only allows one IP address at a time per each user. I started getting an error message in Linux when I booted up saying that my ethernet connection failed. When I called the tech people I was told that because I was switching between Linux and Windoze each one was latching onto an IP address and I needed to release the IP like when I switched back and forth between two computers. I know how to do that in Windoze, it's Run "winipcfg" but I don't know how to do that in Linux. I don't use the internet anymore when I have to go into Windoze and I haven't had that problem since. I hope this helps.

try this...
 

I am no expert in here, but here are a couple of tricks you can use to help you troubleshooot

1.) Try manually bringing up the interface by trying the 2 commands below:

a.) ifconfig eth0 down
[this should make sure the interface is not up]
b.) ifconfig eth0 up
[this should try to bring the interface back up]

2.) Try restarting the network by either
a.) rcroute start
OR
b.) ./network start
[you may have to be in the directory /etc/init.d]


Good luck! :)

How long does it take to time out?

It may not be waiting long enough for your isp's server

Re: try this...
 

Its taking a good 3 minutes to time out.. I've narrowed the problem down to windows. Somehow i can get linux working if i install things that have to do with networking. For instance one time i installed a wizdrake and it worked for a couple reboots, until i loaded windows then rebooted and tried to get back to linux. Everytime i somehow get it working by simply installing something network related like a firewall or something the net works perfectly for numerous reboots until i reboot to windows and then try to go back to linux. Anyone have any ideas on how windows could be messing up DHCP traffic for linux?

I would say it's something in your startup scripts.

try taking some of the stuff out of the ifcfg-eth0 file


ONBOOT=yes
DEVICE=eth0
BOOTPROTO=dhcp



that should be all you need
