Total newbie! eth0 not found after install

mdoss · n00b Joined: 02 Apr 2003 Posts: 11

Hello, I am a complete newbie to Linux and have done something incredibly stupid. I followed the Installation Guide religiously and successfully installed 1.4rc3 and rebooted, only to find that I no longer have an eth0, so cannot connect to the internet or anything.

I did not autoload my network card as a module because I was sure I compiled it into the kernel and not as a module, but now I am not so sure if I did that.

Is there any way I can find out if I compiled my network card as a module or not?

Thanks :)
Mohan

Assuming you haven't changed your configuration file for your kernel you can go back into the /usr/src/linux directory and run make menuconfig and have a look at what you have selected.

Thanks Valen,

I tried what you said, I got:

net.eth0already installed in runlevel default; skipping
Caching service dependencies
rc-update complete

And when I ran /etc/init.d/net.eth0 start I got:

Bringing eth0 up...
Failed to bring eth0 up

Should I run make menuconfig now?

Run lsmod when you are booted from the livecd; that should tell you which type of network card you have in the working install.

Then, when you are chrooted and run make menuconfig, you can make sure you have that same network card compiled into your kernel (or, do it as a module and add it to /etc/modules.autoload).

Then make dep && make clean bzImage modules modules_install
as usual, copy the bzImage to boot, and configure your grub.

Hopefully that will solve the problem!

I cannot chroot. The only way I can chroot is to again start from the livecd stage2 tarball. Is that what i am supposed to do? Gentoo is already installed, can't I boot into that as root and make menuconfig again?

chroot doesn't wipe yor system out or anything. It just creates a shell that is `inside' your system. You can chroot all you want without making any changes to your system.

If you're having trouble chrooting when you've booted off the livecd, make sure you've got your partitions mounted and did the

Thanks Jeff, what you said is exactly what I tried to do and could not. I could not mount proc because proc did not exist once I booted off the livecd and so I could not chroot. That is why I asked if I should start again from stage 2.

I really do not mind starting all over again, hell, I can only learn more by doing that *grin*

There's got to be a step we're missing here, because there is no reason you should not be able to chroot into your install after booting from the live CD. So, if you would humor me, boot the lived CD and then do the following

What type of network card do you have?

What does `dmesg | egrep eth0` return, if anything?

--rtn

As rtn mentioned, looking up "dmesg" should show, whether your kernel finds the card or not. Because you are a newbie (you said so

) I think you could have done everything right without recognizing: type "ifconfig" in your "harddisk-gentoo". If it shows "eth0" your card is running and you just have to configure the IP (ifconfig eth0 192.168.0.2" or something, DHCP also possible).
Tell me if this was your problem

Thanks rtn & c-otto. dmesg returns 'command not found' and ifconfig only shows lo.

I am going now to try what michael said (after booting from the livecd) and get back here with my feedback.

Apparently c-otto, I did not do everything right *grin*

Cheers and thanks again to everyone here for being so patient and helpful.

Michaelb, I did what you asked me to, and it worked! I can chroot again, thank you. I shall now try what arkhan_jg suggested and come back with my feedback.

Thanks once again and cheers

OK, feedback time. My ethernet is a Windbond 840, but I found that I had included all network cards the previous time I did "make menuconfig". Anyway, this time I only included WinBond and did "make menuconfig", after that I ran the make dep and had problems.

Make dep resulted in the following:

make[2]: *** [ksyms.o] Error 1
make[2]: Leaving directory '/usr/src/linux-2.4.20-gentoo-r2/kernel'
make[1]: *** [first_rule] Error 2
make[1]: Leaving directory '/usr/src/linux-2.4.20-gentoo-r2/kernel'
make[: *** [_dir_kernel] Error 2

And then it came back to the system prompt.

Cheers
Mohan

Thank you slartibartfasz. I did not type /bin/dmesg, I only typed dmesg, maybe that was the problem. Anyway, I started the install from scratch again, onlythis time I started from Stage 3.

dmesg gives me an eth0 and an eth1 which is odd because I only have one ethernet in there. Like I said earlier, it is a WinBond 840.

Earlier when I started from Stage 2, I had put the driver in not as a module but built in. I shall be doing the same this time too, followed by make dep etc. I shall keep you all posted on my progress.

By the way I have a question: You mention:

make dep && make clean && make bzImage
make modules && make modules_install

However the install guide grom Gentoo suggests:

make dep && make clean bzImage modules modules_install

Plus you mention:

cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.20

whereas the install guide mentions:

cp arch/i386/boot/bzImage /boot

What is the difference (if any), especially concerning copying the boot image?

Thanks and cheers
Mohan

no difference - its the same - as for the bootimage - thats just the way i name my kernels - u can copy it to 'you_better_work_faster_than_the_old_one' if u like - just be sure to configure your bootloader correctly

OK, feedback and frustration time again :)

I installed from scratch, this time starting from Stage3, followed all instructions to the letter, RTFMed every single option in "make menuconfig" before choosing to include in my compile, chose my correct eth0 and all other devices correctly.

The only difference this time was that (I have 2 hard disks) I chose to install /boot and swap on hdb1 and hdb2 respectively, using hda1 completely for /root.

I made /etc/fstab to reflect my correct drives and partitions for boot, swap and root, I made grub.conf to reflect my driveas and partitions correctly as follows:

title=Gentoo Linux
root (hd1,0)
kernel (hd1,0)/boot/bzImage root=/dev/hda1

Then when I remove the Gentoo CD and boot, I get:

GRUB Loading stage1.5
GRUB loading, please wait...
Error 17

Thank you all. I am grateful to everyone here for their patience and help and very happy to have been treated very well by everyone, but I am giving up. I am going back to a more idiot-oriented distro like Suse or Red Hat.

Thank you all and cheers
Mohan
