DescriptionFile
DNS lookup utility dig (domain information groper) –
Interrogates DNS name servers. This tool performs DNS
lookups and displays the answers that are returned from
the name server (or servers) that were queried. Most DNS
administrators use dig to troubleshoot DNS problems
because of its flexibility, ease of use, and clarity of output.
Other lookup tools tend to have less functionality than
dig.
/usr/bin/dig
DNS lookup utility host – Performs DNS lookups. This
utility is normally used to convert names to IP addresses
and vice versa.
/usr/bin/host
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/nslookup9
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
update request can contain requests to add or remove
more than one resource record.
/usr/bin/nsupdate
18.3 Enabling BIND
The enable script, /usr/sbin/bind9enable, enables either BIND Version 9.2.0 or BIND
Version 8.
To enable a version of BIND:
1. Run the rndc-confgen key 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 18.5:
BIND Documentation. For specific information about the rndc-confgen key 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 9.2.0 or BIND Version 8:
• To enable BIND Version 9.2.0, 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 9.2.0 to run. See Section 18.4: Running the BIND Startup Script for
information on starting the BIND Version 9.2.0 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 18.4: 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
