Mistake with network interfaces

Foxhead · 2010-12-23 05:57:53

During the installation I made a mistake and accidently set it to eth0 instead of eth1. So i nano'ed into /etc/rc.conf and added it but when i boot and type iwconfig eth1 doesn't appear. How can i fix this so i can connect to the internet?

Read this, then if you still have the problem post again

eth is usually cable network, and iwconfig is about the wireless.
Put all your interfaces in rc.conf just to be sure. Maybe your problem is https://wiki.archlinux.org/index.php/Co … es_varying

Well eth might normaly be for ethernet but when i run ifconfig -a from ubuntu i get eth1 as connected and it has the right ip adress and all so it's definitely what's connected. And i went threw the configuring network and the only thing that i can learn from it is that arch doesn't seem to think eth1 exists.

Well i tried reinstalling and first adding eth1 to rc.conf and i realized something weird: during install when i run ifconfig -a eth1 shows up, but after i installed it i ran ifconfig -a and eth1 did not show up. So im guessing im forgetting to install some driver or something that is normally loaded up during the install. I'm kind of new to this advanced of linux so i really have no clue what to fix.

Please post the output of those commands https://bbs.archlinux.org/viewtopic.php … 80#p867880

Foxhead · 2010-12-24 21:01:29

well for ifconfig -a i get eth0 and lo but when i run it in ubuntu i get eth1 eth0 and lo
for dmesg | grep eth i get 4 lines all about eth0 and when run in ubuntu i get an 5 about eth0 and 1 about eth1
for lspci | grep net i get 06:08.0 Ethernet controller: broadcom corp netxtreme BCM5788 gigabit ethernet rev 03
and for lsmod | grep mii i get nothing.

IIRC mii-tool doesn't work with gigabit links, so the lack of output for 'lsmod | grep mii' is OK.
I'm afraid we need the exact output of 'ifconfig -a' and 'dmesg | grep eth'. Why don't you paste it here?

this is from ubuntu btw in arch it gives less info

Please use \[code\] tags

Also, if you are trying to bring up a wireless interface, you need to follow the steps in the wiki: https://wiki.archlinux.org/index.php/Wireless, especially this bit:

First you will need to check and see if the Linux kernel has support for your card or if a user-space driver is available for it.

Foxhead · 2010-12-24 22:28:58

Well it worked with ubuntu right after install so im guessing its compatible.

karol · 2010-12-24 22:29:47

Try this https://bbs.archlinux.org/viewtopic.php … 66#p865366

Arch is not Ubuntu, there are certain differences in the way the kernel and apps work (which version, what patches etc.).

Yes, but if you are asking here for help, then we would like a little more information than your guesses...

If you are trying to use your wireless card, then follow the wiki link I posted. It has everything you need.

Foxhead · 2010-12-25 03:23:25

I apologize. I'm new to this advanced stuff. So i found which drivers i need from this post https://wiki.archlinux.org/index.php/Ac … Networking. Now im only trying to find an Ethernet cable to install them without wireless, but before i tear my house apart im wondering : is there a way i can do it from Ubuntu or with the install disk?
