Network is unreachable

**zachtib** · 03-26-2005

I just booted into my Gentoo enviornment, and everything seemed fine.
but if I do anything that requires an internet connection, emerge, ping, etc
i get a
Network is unreachable error

does anyone know how to fix this?

I have read the other posts in this forum, and none of the solutions there seemed to help.
I'm using an Intel integrated ethernet card

If i boot from the Gentoo LiveCD, the internet works fine, and I can chroot into my system and install packages via portage, but just booting to my system gives the 'unreachable' error, so I'm lead to believe its a problem with the kernel I setup (or not, I'm pretty clueless in this area)

Any help would be greatly appreciated, as a computer without internet access is basically dead to me, and I don;t want to have the last 24 hours have gone to waste by reverting to a previous distro

Could you give us some more information, are you using dhcp, router, static-ip, what do you get when you do:

Code:

ifup eth0

i'm using dhcp and kernel 2.6

Code:

-bash&#58; ifup&#58; command not found

Oh sorry, my bad, I'm used to using redhat, so I wrote a script on my system for a pseudo ifup, for gentoo the script should be in /etc/init.d and should go something like this:

Code:

/etc/init.d/net.eth0 start

Code:

Bringing eth0 up
SIOCSIFADDR&#58; No such device
eth0&#58; unknown interface&#58; No such device
SIOCSIFBRDADDR&#58; No such device
eth0&#58; unknown interface&#58; No such device
SIOCSIFNETMASK&#58; No such device

Code:

dmesg | grep eth

It appears as if you forgot to compile the driver for your ethernet card into your kernel *or* are not loading the module. If the above command doesn't return anything, post the output of 'lspci'.

WOW, thats a lot of errors

Code:

Method execution failed

over and over and over

plus a lot of garble i dont recognize

did you check everything in your kernel that you need for the nic to work? You can always cd /usr/src/linux and make menuconfig and see if anything jumps out at you

btw, how do I use a new kernel once I have compiled it?
do i only have to reboot?
