11.3. Testing the BIND and DNS Configuration

Verify that the broker and node hosts have network connectivity with one another. This is done with either the host or ping commands.

Procedure 11.1. To Test the BIND and DNS Configuration:

  1. On all node hosts, run the following command, substituting your broker host name for the example shown here:
    # host broker.example.com
  2. On the broker, run the following command, substituting your node host's name for the example shown here:
    # host node.example.com
  3. If the host names are not resolved, verify that your DNS configuration is correct in the /etc/resolv.conf file and the named configuration files. Inspect the /var/named/dynamic/$domain.db file and check that the domain names of nodes and applications have been added to the BIND database. See Section 7.3.2, “Configuring BIND and DNS” for more information.

Note

BIND might maintain a journal under /var/named/dynamic/$domain.db.jnl. If the $domain.db file is out of date, check the $domain.db.jnl file for any recent changes.
