nsupdate Command

Purpose

Updates a DNS server.

Syntax

Refer to the syntax for the nsupdate4, nsupdate8, or nsupdate9 command.

Description

AIX® 7.1 supports only BIND version 9. BIND 8 application code is removed from AIX 7.1. The named daemon links to the named9 command and the nsupdate command to links to the nsupdate4 command now. To use a different version of the nsupdate command, you must relink the symbolic links to the nsupdate command.

For example, to use the nsupdate9 command, enter the following command:

ln -fs /usr/sbin/nsupdate9 /usr/sbin/nsupdate

The nsupdate4 command can be used with the named8 command (which is now removed from AIX 7.1). However, the nsupdate9 command must be used with the named9 command because the security process is different.
