[gentoo-user] Network works OK internally but can't access Internet - very frustrated

Hi - After a last emerge --sync I've been having trouble accessing the internet. My network interface comes up OK. I receive an address for the DHCP server (i.e. "eth1 received address 192.168.0.7/24") and I can see and access my Intranet webpage on 192.168.0.xx and copy files to and from various machines. 

However if trying to access the Internet I keep getting "unknown host" when pinging sites I know will respond. My machine dual boots into XP and runs fine. 

I've checked the Gentoo handbook and config files and confirmed my network config files look OK (they seem to). Can anyone offer any suggestions? 

Thanks, Richard

If you just did emerge --sync, the problem that you have was not
caused by this command. Do you have your dns configuration correct?
please check you /etc/resolv.conf file. Does your DHCP server send
nameserver to the client?

Thanks for your reply. When the interface is up /etc/resolv.conf has a name 
change to /etc/resolve.conf-eth2.sv and contains the following:

# Generated by dhcpcd for interface eth0
nameserver 61.9.208.14
nameserver 61.9.208.15

Which is the primary and secondary DNS on my cable modem for Telstra. So I 
guess the DHCP server is sending the nameserver info. Still no go ...

Regards, Richard

Can you ping those addresses?

It is of no use under other name. You need it to be exactly
/etc/resolv.conf.

Sounds like you aren't getting to a nameserver.

Check /etc/resolv.conf and make sure there are 1 or more entries for a
pingable nameserver:

It should say something like

nameserver  xxx.xxx.xxx


If it does, try ping the ip numbers listed.  If that works then the
problem is else where.

Does your resolve.conf start with "# Generated by net-scripts for  
interface"? If yes, then check /etc/conf.d/net for something like

dns_servers_eth0=( "62.148.128.1 62.148.128.22" )
