Internet works with Knoppix but not Gentoo

Penguin of Wonder · 01-18-2006, 06:49 PM

I'm in the process of switching to Gentoo, but I can't get the internet to work during the installation. The Gentoo Install/LiveRun CD see's my ethernet card but it dosen't properly configure it or something. On the other hand, my Knoppix LiveRun CD properly gets the internet to work, I can even ping yahoo from the prompt

Code:

ping -c 3 www.yahoo.com

and it returns output saying all three sent and we're recieved with no errors. I know Gentoo can see my card because when I run

Code:

/sbin/ifconfig

it returns for both eth0 and lo. When I run this command in Gentoo, it see's both eht0 and lo as well, but it returns different values for the various addresses and such.

So my question is, can I use Knoppix to see how to set up my ethernet card properly, and then use those settings in Gentoo? And naturally, if I can do that, how would I go about it (all from the console of course

).

Thanks guys!

It may be as simple as running /sbin/dhcpcd eth0. This causes your card to request an IP address via DHCP. If this doesn't work, maybe you could post the differences you found between the two ifconfig outputs? That may be of some help.

BTW dhcpcd probably has to be run as root.

Here is my Knoppix output for eth0 after running /sbin/ifconfig:

Code:

Link encap:Ethernet  HWaddr 00:E0:4C:D8:38:96
inet addr:10.101.221.176 Bcast:10.101.223.255 Mask:255.255.252.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:3186994 (3.0MiB) TX bytes:40667 (39.7 KiB)
Interrupt:18 Base address:0x4000

And here is my output using Gentoo:

Code:

Link encap:Ethernet  HWaddr 00:E0:4C:D8:38:96
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:113 errors:0 dropped:0 overruns:0 frame:0

RX bytes:14105 (13.7KiB) TX bytes:1240 (1.2 KiB)
Interrupt:18

It dosen't take long to notice alot is missing from Gentoo output. Even I can tell that's one important looking line :P.

--------------------------------------------------

The command

Code:

/sbin/dhcpcd

returns the following

Code:

**** /sbin/dhcpcd: already running
**** /sbin/dhcpcd: if not then delete /var/run/dhcpcd-eth0.pid file

When i'm running Gentoo. Hope this helps some more.

Alright guys, I solved my own problem... on accident.

On boot I issued the following command

boot: gentoo nodhcp

After it finished booting, I pinged Yahoo! and now the internet works just fine. Why, you might ask, did i disable DHCP upon boot? Because I was going to try to configure the whole thing myself, but I decieded to ping Yahoo! first just for the dumb luck of it. Turns out I'm dumb lucky today :P

Thanks for the responce Maestro485! According to the boot options menu, disabling DHCP might help people who have static IP addresses... so I'm assuming that's why it worked for me. I apparently have a static IP address or something.
