Commands Reference, Volume 4

named Daemon

Purpose

Provides the server function for the Domain Name Protocol.

Syntax

Refer to the syntax for either the named4, named8, or the named9 daemon.

Description

AIX supports three versions of BIND: 4, 8, and 9. By default, named links to named4, nsupdate to nsupdate4, named-xfer to named-xfer4. To use a different version of named, you must relink the symbolic links accordingly for the named and named-xfer daemons.

For example, to use named8:

ln -fs /usr/sbin/named8 /usr/sbin/named 
ln -fs /usr/sbin/named8-xfer /usr/sbin/named
nsupdate4

can be use with named8, but nsupdate9 must be used with named9 because the security process is different. It does not matter what named-xfer is linked to when using named9 because the daemon does not use it.
