Configuring and Managing BIND
5.7 Configuring the BIND Resolver
This command modifies the volatile database. To make changes permanent, also
enter a SET CONFIGURATION NAME_SERVICE command to add the change to
the permanent database. Enter a SHOW CONFIGURATION NAME_SERVICE
command to view the results.
5.7.1 Changing the Default Configuration
To add a new server and enable the BIND resolver, enter the following command:
TCPIP> SET NAME_SERVICE /SERVER=host /ENABLE /SYSTEM
For host, specify the host name or IP address of the BIND server or servers that
the BIND resolver is to query.
To specify multiple hosts, list them by request preference. The BIND resolver
sends the first lookup request to the first host on the list.
If you define a server list and then add a new server with the
SET NAME_SERVICE /SERVER command, the new server is added to the
end of the list.
SET commands affect the volatile database. To save your changes to the
permanent database, use the SET CONFIGURATION commands. The changes
you make with the SET CONFIGURATION commands take effect the next time
the software starts up. For example:
TCPIP> SET CONFIGURATION NAME_SERVICE /SERVER=host /ENABLE
TCPIP> SHOW CONFIGURATION NAME_SERVICE
BIND Resolver Configuration
Transport: UDP
Domain: ucx.ern.sea.com
Retry: 4
Timeout: 4
Servers: 9.20.208.47, 9.20.208.53
Path: No values defined
5.7.2 Examples
The following command defines hosts PARROT, SORA, and JACANA as
systemwide BIND servers and enables the BIND resolver:
PARROT> TCPIP
TCPIP> SET NAME_SERVICE /SERVER=(PARROT,SORA,JACANA) /SYSTEM /ENABLE
The following example defines, for the current login session, host OSPREY as
the BIND server. As a result, the servers that are defined systemwide are not
queried.
TCPIP> SET NAME_SERVICE /SERVER=OSPREY
5.7.3 Resolver Default Search Behavior
By default, if no search list is defined and the host name as you typed it has no
dot (.) in the name, the BIND resolver performs a lookup using the following
forms of the host name:
1. The host name, with the default domain appended
2. Just the host name
For example, suppose you enter the command:
TCPIP> SHOW HOST OWL
