/usr/bin/nslookup9

DNS lookup utility – Displays the following message: “Note:

 

nslookup is deprecated and may be removed from future

 

releases. Consider using the `dig' or `host' programs

 

instead. Run nslookup with the `-sil[ent]' option to prevent

 

this message from appearing.?

/usr/bin/nsupdate

Dynamic DNS update utility – Submits Dynamic DNS

 

Update requests as defined in RFC 2136 to a name server.

 

This allows resource records to be added or removed from

 

a zone without manually editing the zone file. A single

Enabling BIND

The enable script, /usr/sbin/bind9enable, enables either BIND Version 9.3.6-P1 or BIND Version 8.

To enable a version of BIND:

1.Run the rndc-confgenkey generation tool. This tool provides a convenient method for generating configuration files for the rndc name server control utility and must be run prior to enabling a version of BIND. See the README.1st file in the documentation provided with the software for more information and review the BIND documentation in Section : BIND Documentation. For specific information about the rndc-confgenkey generation tool, see the rndc-confgen(8) reference page. For information about the rndc name server control utility and associated configuration file, see the rndc(8) and rndc.conf(5) reference pages.

2.Use one of the following methods to enable either BIND Version 9.3.6-P1 or BIND Version 8:

•To enable BIND Version 9.3.6-P1, enter /usr/sbin/bind9enable v9 from the UNIX command prompt.

The enabler script copies sbin/init.d/named9 to sbin/init.d/named, allowing BIND Version 9.3.6-P1 to run. See Section : Running the BIND Startup Script for information on starting the BIND Version 9.3.6-P1 server.

•To enable BIND Version 8, enter /usr/sbin/bind9enable v8 from the UNIX command prompt.

The enabler script copies sbin/init.d/named8 to sbin/init.d/named, allowing BIND Version 8 to run. This version of BIND reverts back to the currently installed version of BIND. See Section : Running the BIND Startup Script for information on starting the BIND Version 8 server.

3.The sysman utility adds a directory statement in the options section of /etc/namedb/ named.conf upon configuration of a BIND server. The /usr/sbin/bind9enable script copies the datafiles from /etc/namedb to /etc/namedb9. The network administrator will need to either remove the directory statement to permit named9 to read files from its default location (/etc/namedb9) or the administrator may update this statement to reflect the new location.

By default, the named daemon is built to read files from the sbin/init.d/ directory. You can change this default with an options statement in your named.conf file.

If you cluster a standalone system, you must rerun /usr/sbin/bind9enable.
