FreeBSD: Set Primary Nameserver(s) in resolv.conf
I’ve been having trouble with my ISP’s nameserver so I wanted to switch over to Google’s public DNS.
The issue I had was that each time I rebooted my system resolvconf would
be provided with my ISP’s nameserver (as part of the DHCP process) and
would set this in /etc/resolv.conf. This replaced any changes I made during
my last session (as it should).
After a poke around in the man pages resolveconf(8) and resolvconf.conf(5)
I found that I could prepend a set of nameservers to my resolv.conf. It would
then fall back to any other nameservers provided to resolvconf when required.
This can be done simply by adding the following to /etc/resolvconf.conf
(create this if it isn’t there):
# Replace with the ip(s) of your chosen nameserver
name_servers="8.8.8.8 8.8.4.4"
You can then regenerate /etc/resolv.conf using:
$ resolvconf -u
And your /etc/resolv.conf should look something like:
$ cat /etc/resolv.conf
# Generated by resolvconf
search lan
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 192.168.1.254
Enjoy!
