Re: Problem with DSL and /etc/resolv.conf

Hi Andrew

I know your original posting is old (Oct 2004) and you have probably 
solved the problem in some way by now, but I thought I'd post my 
solution to your problem so that other may benefit from it.

This solution assumes that you are using dhclient for your DHCP client. 
If you create a file called dhclient-enter-hooks in /etc, you can then 
change the way dhclient modifies your resolv.conf file (man 
dhclient-enter-hooks). My dhclient-enter-hooks file looks like this:

make_resolv_conf() {
        echo nameserver xxx.xxx.xxx.xxx | resolvconf -a eth0
}

where xxx.xxx.xxx.xxx is the IP number of the ISP nameserver.

I use the utility resolvconf to manage my resolv.conf file, but if you 
don't then you could do something like:

make_resolv_conf() {
        echo nameserver xxx.xxx.xxx.xxx > /etc/resolv.conf
}

I haven't check that this works when the DHCP lease expires and is 
renewed, but I assume that it will.

I hope this helps others with this problem.
