You can write a script to fix resolv.conf right after dhclient ruined
it. The way to do it is to hook it from /etc/dhclient-exit-hooks
(which you'll need to create). Here's mine, which calls two other scripts (not
included), one of which only if the IP address actually changed. This one
also gets the new servers as arguments.
-- /etc/dhclient-exit-hooks
# nothing to do unless we're bound
case ${reason} in
BOUND | RENEW | REBIND | REBOOT )
[ -x /etc/set-ntp ] && . /etc/set-ntp
if [ -n "${new_domain_name_servers}" ]; then
if [ -z "${old_domain_name_servers}" ] || [ x${old_ip_address} !=
x{$new_ip_address} ]; then
[ -x /etc/refresh-named ] && /etc/refresh-named
${new_domain_name_servers}

Re: dhcp option to *not* overwrite /etc/resolv.conf
add this to your /etc/dhclient.conf
interface "(outside interface)" {
supersede domain-name-servers (preferred DNS);
}
you can alternately use prepend domain-name-servers to add your DNS to the
TOP of the resolv.conf list.

man dhclient.conf
As an example my /etc/dhclient.conf contains the following:
interface "ed0" {
supersede domain-name-servers 127.0.0.1;
append domain-name " example.com";
}
The resulting /etc/resolv.conf looks like this:
search isp.domain.com example.com
nameserver 127.0.0.1

OpenBSD supports use of a resolv.conf.tail file that also hold entries you don't want overwritten (no idea about FreeBSD).

Re: dhcp option to *not* overwrite /etc/resolv.conf
Never tried it, but you could look for the spot in the various rc* files that setup dhcp and once it's done re-write /etc/resolv.conf with what you want it to be... ?

dhcp option to *not* overwrite /etc/resolv.conf
Hi, I have read the man pages, searched a few forums, but I did not found a way to prevent dhcp to do not change my /etc/resolv.conf. I do not have access to the dhcp server configuration, so I need to change it on my client. I also tried to chmod it to only read mode, but that did not work out. Any tips? thanks Paulo __ Do you Yahoo!? Y!
