eth0 not working

Hardware
toshiba laptop
turion 64 x2
2 GB ram
OS: dual boot vista + gentoo

Problem:

Installed gentoo from the 32bit livecd due to problems with amd64 livecd.

once installed i rebooted the system and connected rj45 cable from my sky box router the network interface doesn't show any green light on it. i tried manually entering the ip, rebooting, bringing the device up and down with no luck. i rebooted into vista and tried the rj45 cable again which works fine. I'm guessing it's a driver problem or i've messed something up. can anyone help me?

Looks like you have to setup your /etc/conf.d/net file with the correct options. You have a broadcast address of 192.168.1.255 and an ip of 192.168.0.5/24. That isn't going to work. Please refer to the handbook to update your network configuration.

It looks to me that your eth0 is not your ethernet card at all but ethernet over firewire (I'm assuming this due to the extra 00-00's a the end of the MAC address). Do an 'ifconfig -a' to list all network devices.

If your ethernet card is not listed here (probably as eth1) make sure you have the driver compiled into your kernel or installed as a module. It is likely that the livecd is loading your drive as a module, so you can see which driver is being loaded for your ethernet card there if you are unsure.

config_eth0("192.168.0.2/24 brd 192.168.0.255")
config_eth0("192.168.0.2/24 netmask 255.255.255.0 broadcast 192.168.0.255")

You were right it was down as eth1 i've gone thought the command to get it up and running and it's still having the same problem

commands used

ifconfig eth1 192.168.0.7 broadcast 192.168.0.255 netmask 255.255.255.0 up
route add default gw 192.168.0.1

still not receiving any packets, i can't ping my router.[/post]

Maybe your settings are off. Why not try connecting via dhcp once to verify your settings then edit your /etc/conf.d/net accordingly?

If you want to use dhcp then you don't need to add anything to that file. If you want to use a static IP then you would want to add something like this:

Code: Select all

config_eth1=( "192.168.0.7/24" )
routes_eth1=( "default via 192.168.0.1" )

Also, try starting your ethernet device using /etc/init.d/net.eth1 instead of doing it manually.

i ran the command
/etc/init.d/net.eth1

result

bash: /etc/init.d/net.eth1: no such file or directory

so i ran

ls /etc/init.d/

result

net.eth0 net.lo netmount

How do i create net.eth1 and configure it?

Kris87,

Your MAC address shows you have ethernet over firewire as your eth0.

If your real network module is loaded (I suspect not, or the lights on the port would be lit) it will appear in

Code: Select all

ifconfig -a

Post your lspci and we can tell what module you need or try this guide which shows you how to compare what works for the liveCD with what you have in your own install.

Do this:

Code: Select all

ln -s /etc/init.d/net.lo /etc/init.d/net.eth1

This is all covered in the gentoo handbook in chapter 8b, which may help you through the rest of your configuration:

It's still not working

the dhcp server says
after the command

/etc/init.d/net.eth1 restart

results:

starting eth1
bringing up eth1
dhcp
running dhcpcd......
error, timed out waiting for a vaild DHCP server response [!!]

I'm pretty sure the driver must be laoded if you are able to bring the device up/down, but:

Can you verify that you have CONFIG_USB_RTL8150 either compiled in or built as a module in your kernel? If it is a module, can you verify it is loaded in the lsmod output?

Can you also post the eth1 portion of the output of 'ifconfig -a'?

If you are trying for dhcp, is the contents of /etc/conf.d/net blank?

Finally... I'm assuming that your router is working properly. It does work off the livecd correct?

EDIT: BTW - is this your laptop model? I noticed that it was a toshiba and also had the same ethernet card inside. This link may help:
