7.3.2.2. Configuring Host Name Resolution

Procedure 7.7. To Configure Host Name Resolution:

1. Edit the /etc/resolv.conf file on the broker host.
2. Add the following entry as the first name server:

   nameserver  127.0.0.1

   Copy to Clipboard Toggle word wrap
3. Save and close the file.
4. Open a shell and run the following commands. This allows DNS access through the firewall, and ensures the named service starts on boot.

   # lokkit --service=dns
   # chkconfig named on

   Copy to Clipboard Toggle word wrap
5. Use the service command to start the named service (that is, BIND) for some immediate updates:

   # service named start

   Copy to Clipboard Toggle word wrap
6. Use the nsupdate command to open an interactive session to BIND and pass relevant information about the broker. In the following example, server, update, and send are commands to the nsupdate command.

   Important

   Remember to replace broker.example.com with the fully-qualified domain name, 10.0.0.1 with the IP address of your broker, and keyfile with the new key file.
   Update your BIND configuration:

   # nsupdate -k $keyfile
   server 127.0.0.1
   update delete broker.example.com A
   update add broker.example.com 180 A 10.0.0.1
   send

7. Press Ctrl+D to save the changes and close the session.
