How to Enable OpenDNS: Unix/Linux BIND


Overview

  1. Find the BIND configuration file that contains the options statement.
  2. Inside the options statement, add a forwarders statement that lists the OpenDNS servers.
  3. Reload BIND's configuration.

Print-ready instructions

1. Find the BIND configuration file that contains the options statement.

If /etc/bind/named.conf.options exists on your system, it probably contains the options/etc/named.conf, /etc/bind/named.conf, or /etc/namedb/named.conf. statement. Otherwise, look for it in

The options statement resembles this:

options {
...
};

2. Inside the options statement, add a forwarders statement that lists the OpenDNS servers.

If a forwarders statement already exists, replace it.

The options statement should now resemble this:

options {
forwarders { 208.67.222.222; 208.67.220.220; };
...
};

3. Reload BIND's configuration.

The method for this varies from system to system, but is likely to be rndc reload (for BIND 9) or ndc reload (for BIND 8).
