Network not working after kernel configuration

Hi

I have been using Gentoo since last 15- 20 days

My usb wifi rtl8187 was not working since first day i tried with kernel recompilation and now my Ethernet is also not working.

when i do
Ifconfig -a
lo link encap:local loopback is active only.

#/etc/init.d/net.eth0 start
* starting eth0
* Bringing up eth0
* 10.8.85.109
* network interface eth0 does not exist
* please verify hardware or kernel module (driver)

#lspci
0a:00.0 Ethernet controller: Realtek Semiconductor co., Ltd. RTL8101E/ETL8102E PCI Express Fast Ethernet controller (rev 02)

Please help me

Okay :-/

Let's look at your system logs. I use /var/log/kern.log instead of /var/log/messages

Oh, by the way -- Your uname output indicates you had not set your time zone prior to compiling the kernel. If you haven't, you may want to take care of that.

Hi

I don't have kern.log in /var/log. instead of that i have genkernel.log. please check the output of same.

log# grep 8169 genkernel.log

I am actually looking for what is happening during boot. I think genkernel.log tells us how the kernel was built. Do you have syslog or messages logs?

If not, try:
dmesg | grep 8169

edit: it is 23:25 local. Good night. I'll pick this up in the AM

Good Morning.
Okay, lets try a different tack. It looks like you used genkernel when you installed the OS which (IIRC) means that your driver should be compiled as a module:

It is possible that he emerged a new kernel, configured it, and never switched to it. Checking the contents of /proc/config.gz, assuming it is present, is more reliable than peeking at /usr/src/linux/.config. The configuration in /proc is guaranteed to be from the running kernel.

Slightly off-topic: for users that install via make install rather than a manual copy, inspecting /boot/config-$(uname -r) can also be helpful, though this assumes a mounted /boot, which not everyone will have. From most to least reliable:

/proc/config.gz (requires IKCONFIG=y IKCONFIG_PROC=y)
/boot/config-$(uname -r) (requires mounted boot and install via make install or equivalent)
/usr/src/linux-$(uname -r)/.config (requires kernel was built locally and no tricks with fancy naming)
/usr/src/linux/.config (requires a /usr/src/linux symlink and assumes the symlink points to the active kernel)

OP: as a typo correction to the post immediately above mine, please provide the output of eselect kernel list, not eselect kenel list as written there.

And Whel i run

# modprobe r8169
FATAL: Module r8169 not found.

yes i am using root. will it give any problem if i keepon using it as root.

Okay, I am convinced the driver is compiled in to the kernel in /usr/src/linux/arch/i386/boot/bzimage has your r8169 driver built in, and that you have correctly run make modules_config

I believe this because:
1. You started with genkernel, and at that time, the driver was a module.
2. Your configuration specifies that the r8169 driver be built in.
3. There no longer is an r8169.ko module.

What I wonder is whether the kernel you are running is actually the one in /usr/src/linux/arch/i386/boot/bzimage. Can you please check the file length and creation date.:

ls -l /usr/src/linux/arch/i386/boot/bzimage
mount /boot
ls -l /boot

And, just in case there are multiple kernels in /boot, post the output of cat /boot/grub/menu.lst

Other things you should fix on your system:
Add vixie-cron and syslog-ng to your default run level using rc-config
You may want to add net.eth0 to your boot runlevel (unless you use something like Netmanager instead)
You should to clean up your timezone stuff
Get the wireless working

I missed that you are using *_64

Your new kernel is at /usr/src/linux/arch/ia64/boot/bzimage
Check the creation date on that file and see if it is newer than January 4.

There is some weirdness here:

ajaywithms · n00b Joined: 09 Jan 2011 Posts: 11

I don't have /boot directry under /usr/src/arch/ia64/
Please see
#ls /usr/src/arch/ia64/
kconfig kconfig.debug Makefile configs dig hp include install.sh kernel kvm lib mm module.lds oprofile pci scripts sn uv xen

I am booting with same kernel since starting. my eth0 was working erlier and my laptop' internal wireless was also working.

I tried recompilation of kernel becuse my usb wireless card rtl8187 is not working. since then my eth and internal wireless not working.

ia64 is itanium, that's not correct

yours is x86, even if it's 64 bit, the kernel you need to check the date on is at /usr/src/linux/arch/x86/boot/bzimage

ensure boot is mounted and run these two and post them here, to actually confirm you're running the version of the kernel you compiled.

ls -la /usr/src/linux/arch/x86/boot/bzimage
ls -la /boot/

chances are what you've either done is mismatched kernel modules, or you aren't actually running the kernel you think you are, this should clear that up.
