*sigh* Network suddenly not working. Hopefully simple prob.

SilverSnake

Heya,

Haven't booted my Gentoo install in quite some time now and now wanted to check out some new stuff I've found. Booted up just fine, as normal, but networking isn't working. I ran ifconfig to reset all my information for eth0 and made sure I got my static IP right and all. Ifconfig -a shows my eth0 interface to be "up and running", and running a /etc/init.d/net.eth0 restart gives no errors at all.

I can't find anything that seems to be wrong, except that ifconfig -a also shows a dummy0 interface, which is listed on top, followed by my eth0 and lo. I can't recall seeing it there before.

Note that my networking has worked fine before and I can't recall what the last thing I did before it stopped working was, since it was quite some time ago, but I'm pretty sure I didn't recompile my kernel (thus removing the support for my NIC, which is compiled into the kernel, not running as a module).

I'm running RC9 of Gentoo. I hope we can find some easy solution for this, otherwise, don't put too much energy into it, I'll just make a clean install of the latest version.

Thanks in Advance!

Hey there. I'm not a pro yet in linux networking, but know quite a bit about it in winblows world (because of my work). What I usually do first is to see if ip is running correctly by pinging 127.0.0.1 which will always ping your own nic and no further. Then if you had dhcp try with staic ip making sure subnet and gateways are correct.

give it a shot see if it helps

there's an option in your kernel config for a dummy nic... perhaps take that out, or unload the module if it's loaded.

what does lsmod show ?

Well, it seems weird if it would be some module that's loaded all of a sudden, because I'm fairly sure I wasn't fiddling with that when it all stopped working.

Could you please remind me of the name of the file where all the modules that's loaded on startup is listed and/or how to unload a module on the fly so I can try and do that when I reboot to check out lsmod?

Thanks

You can disable the dummy with "ifconfig dummy0 down". Also check your routing table:

My routing table looked just fine... *sigh*

I'll just reinstall, will save me a lot of doublecompiling anyway since I need to upgrade most of my stuff anyway.

Thanks for trying to help though
