I was trying diferent combinations and not works,how i configure that script?

/etc/resolv.conf is a configuration file, not a script.

What exactly did you try, and what were you trying to accomplish?

To specify a nameserver, use the "nameserver" directive (for instance, nameserver 8.8.8.8). man resolv.conf will tell you about the various configuration options.

Read the book:
http://www.linuxfromscratch.org/lfs/...7/network.html

resolv.conf gets overwritten by network configuration helpers like DHCPD or NetworkManager. To manage your nameservers with helpers present you have to configure them instead. Only if your network configuration is totally manual - I. E. no helpers are running - editing resolv.conf will work.

Since your new LFS system booted for the first time only a few hours ago today, I doubt that things like NetworkManager or DHCP and their effect on resolve.conf are involved here yet. I could be wrong in this case though. Sometimes people do like to go straight to dynamic IP addressing over the static IP addressing in the LFS book.

I wonder if your problem is possibly the configuration of your network device (i.e., drivers, firmware, config files, etc.). Anyway, problems with those things seem to be way more common at this early stage IMO.

I recommend that you take a moment to describe what the problem actually is and what you've accomplished so far to configure the network device and confirm it's being brought up and acquiring an IP address from your access point. Resolving DNS addresses is of no importance until that kind of stuff is right and working. Maybe the network device is connected and working, but there's no way to tell from the posts so far.

Ok, i am going to explain my problem.
When i rebooted lfs for the first time I tried to conect to google (ping google.com) , i think the error is in the /etc/resolv.conf file, but i am not sure.
How i conect to internet?

What's happened exactly? What have you really tried to do? Is there an error message somewhere?
Have you tried traceroute? do you have network at all?

I tryed all the resolv.conf nameservers and domains, but no works, when i put ping google.com it shows that messange:
Ping:inaccesible network, i doent tryed traceroute and yes, i have network via ethernet

can you ping your router, other hosts on your local network?

No, i can not

so probably you have no (working) network at all. Can you check it?

i have network yes, when i am in the host system (xubuntu) all works correctely,when i go to lfs all eth0 goes bad.

what do you mean by "all eth0 goes bad" ?

its, abit hard to follow, have you booted into lfs and there is no network?

output would help and post you resolve.conf from lfs.

Actually lspci -k would help to see if the driver is loaded.
