Hi everyone
i've done for LFS 6.3 for a month but can anyone tell me how to continue in BLFS.I've try to config eth0 interface but not work anf how me know that my LFS is stable how to check(it is work fine? is it 100% done?)

You've already gotten further than I ever did with LFS. It will boot to a bash prompt?

yes is it. but eth0 not work and always got same Error seem like didn't have driver for that device.

What do you want to do with BLFS? I have gone through it and was able to install the KDE desktop. If you want i can give you a list of the items in the BLFS that you need to do to get KDE up and running. Takes some time but is not that bad.

Also with eth0 i had to make sure when i was building the kernel that i included the correct network driver for my network card.

What, exactly, is the problem you are having with eth0? What have you tried already? What error messages, if any, are you recieving?

In the new LFS system do the following to get your network working correctly.

rm -v /etc/udev/rules.d/70-persistent-net.rules

This will remove the current net interfaces that you configures with the original host.

/lib/udev/write_net_rules all_interfaces

This will recreate the file for your system correctly.

cat /etc/udev/rules.d/70-persistent-net.rules

now find your network card listed in the file and configure your /etc/sysconfig/network-devices/ to the correct device. Often all you have to do is rename the dirictory that your network config is in then in the /etc/sysconfig/network-devices/ folder do a

./ifup eth#

It should now be working.
