nsupdate Command

Purpose

Updates a DNS server.

Syntax

Refer to the syntax for the nsupdate4, nsupdate4or nsupdate9 command.

Description

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

For example, to use nsupdate9, type:

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

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