The name server daemon, /usr/sbin/named, must be running on all the master, slave, and caching-only name servers. If you have configured your system to query a remote name server (that is, if you have created an /etc/resolv.conf file that directs BIND queries to a name server on another host), you need not run the named daemon on your host.
Before you start the name server daemon, ensure that syslogd is running. syslogd logs informational and error messages. For information on configuring syslogd, see the HP-UX Internet Services Administrators Guide at the URL http://www.docs.hp.com/hpux/netcom/index.html#Internet%20Services.
Follow these steps to start the name server daemon:
In the /etc/rc.config.d/namesvrs file, set the NAMED environment variable to 1, as follows:
Issue the following command to determine whether named is already running:
If named is not running, issue the following command to start named:
For more information, type man 1M named at the HP-UX prompt.
Verifying the Name Server |

You can use nslookup to query the name server interactively by specifying either the host name or the respective IP address of the host. nslookup displays the host name and IP address of the queried host.
To check whether the name server is configured properly, perform the following steps:
Start nslookup using the following command:
At the > prompt, specify the name server you want to test in the server command as follows:
> server BIND_server_hostname |
> server indigo.div.inc.com |
The server command causes nslookup to use the host indigo.div.inc.com as the name server for all the queries.
At the > prompt, type the host name for the name server to look up, as in the following example:
charlie is a host in the domain div.inc.com, where indigo.div.inc.com is configured as the name server. Therefore, the following output is displayed at the > prompt:
Name Server: indigo.div.inc.com
Addresses: 15.19.14.100, 15.19.15.100
Name: charlie.div.inc.com
Address: 15.19.9.100 |
In the name server’s domain (that is, div.inc.com), look up several host names and IP addresses of hosts and check whether the respective host names and IP addresses displayed are correct.
At the > prompt, type the following commands to verify that your name server queries root name servers:
nslookup must display a list of all the root name servers in the db.cache file. If nslookup does not display the root name servers, see “Troubleshooting the BIND Name Server”.
If you are running syslogd, you can check the error messages in the /var/adm/syslog/syslog.log file. For more information, see “Troubleshooting the BIND Name Server”.
Type exit to exit from nslookup.
