[gentoo-user] Lost nameserver

[gentoo-user] Lost nameserver

[Thierry de Coulon]

Hello,

I'm in the process of compiling a new system using 2006.1 (minimal 
install/amd64). My only problem at the moment is that every time I start the 
system the nameserver information has diseapeared from /etc/resolv.conf.

There is a text line saying that the file was "created by the net scripts" so 
I guess resolv.conf gets re-created at each boot, but I don't find in 
which "net script" I should pour the nameserver information so that it gets 
into resolv.conf each time.

/etc/conf.d/net

Set dns_servers_eth0 (or whatever is correct for your network interface).

It looks like the system is currently trying to set them by DHCP but your
DHCP server is not giving out DNS information.

Thanks, I'll try that.

As a matter of fact my DHCP server can't give out DNS information as I have no 
DHCP server and use fixes IPs :)

In that case, you may not want to use DHCP to configure your devices ; )

I don't use it (or at least I never intended to). I've set up a network 
configuration with fixed IPs and copied the configuration files as instructed 
in the handbook - well, maybe I made a mistake somewhere...

In all likelihood, you didn't edit /etc/conf.d/net for one of your
network interfaces, which ifplugd then tried to bring up.  you may want
to change /etc/conf.d/rc.

Yes, I did edit /etc/conf.d/net. Actually everything works correctly (I get 
the correct IP on the correct card and the gateway is also correct). the only 
thing that does not work is that I have no dns setting so I can't download 
the sources to install.

I can add "nameserver <IP>" in /etc/resolv.conf but it's gone at the next 
reboot. I've now added dsn_servers_eth0 in /etc/conf.d/net and I'll see next 
time if I get the dns right.

Have you read /etc/conf.d/net.example? This part may apply here:

# NOTE: Setting any of these will stamp on the files in question. So if you
# don't specify dns_servers but you do specify dns_domain then no nameservers
# will be listed in /etc/resolv.conf even if there were any there to start
# with.

Hum, no, I did not - I blindly followed the handbook

That's It! However, this must have changed more or less recently, as I never 
had the problem with my older Gentoo install (based on the 2005 version).

Thanks a lot, next time I'll take the time to read the example.
