resolv.conf

I am using Red Hat Enterprise Linux 3. Can someone tell me
exactly what belongs in /etc/resolv.conf if you are using dhcp to
set the IP address and the DNS?

Just an example
cat /etc/resolv.conf
search localdomain attbi.com
nameserver 204.127.202.204
nameserver 216.148.227.268

Nothing, dhcp client should take care of it, if configured
probably.

inconvenience, but I get tons of SPAM

What goes into /etc/resolv.conf is the address of the DNS server. If
your dhcp sticks it into there, that is fine. If not then you have to
stick in the address of some dns server.

You can put anything you want in /etc/resolv.conf, as it will
be over-written the moment that DHCP gets the info from
the ISP. :-)

Normally, if using DHCP client, you don't put anything in
/etc/resolv.conf. It will happen auto-magically when dhcp-client
gets going. The script /sbin/dhclient-script does the work.

If you really must stick something in /etc/resolv.conf and are
a dhcp client, then you will probably want to edit
/sbin/dhclient-script.

In the script you will find the function make_resolv.conf()

Here is an example where I have added stuff to stick in
/etc/resolv.conf.

function make_resolv_conf() {
if [ -n "$new_domain_name" ] || [ -n "$new_domain_name_servers" ]; then
echo '; generated by /sbin/dhclient-script' > /etc/resolv.conf
if [ -n "$new_domain_name" ]; then
echo search $new_domain_name >> /etc/resolv.conf
fi
echo search home.org >> /etc/resolv.conf
echo nameserver 192.168.164.253 >>/etc/resolv.conf
echo nameserver 47.124.35.253 >>/etc/resolv.conf
for nameserver in $new_domain_name_servers; do
echo nameserver $nameserver >>/etc/resolv.conf
done
fi
}

Note: The above is ugly, and should not be needed if the DHCP
server is working correctly.

Note: The above discussion is for a RH box.

Alternatively just put what you want into /etc/resolv.conf after dhcp
has come up.
