[SOLVED] Configuring resolv.conf

Mint 18.3 Sylvia
Kernel: 4.8.0-53-generic x86_64 (64 bit)

My /etc/resolv.conf is a symlink to /run/resolvconf/resolv.conf. The header says "Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)"

My question: is there a config file that I can edit to change/rearrange the choices in that dynamic file? Neither /etc/host.conf nor /etc/hosts offer that.

I guess systemd or Networkmanager puts that together for you - both things I know little about. Can you junk the symlink and write your own?

The key is the /etc/dhcp/dhclient.conf file. Simply add the following option

Code:

append domain-name-servers xxx.xxx.xxx.xxx;

just after the option

Code:

rfc3442...

at the beginning of the file. The result is to use the local connection's discovered DNS first, then follow with the preferred DNS listing.

Using the

Code:

prepend

keyword puts the preferred DNS first.

Not as hard as I expected it to be.
