Using the rndc Utility
The rndc utility is a command line tool that allows you to administer the named service, both locally and from a remote machine. Its usage is as follows
rndc [option...] command [command-option]
Configuring the Utility
To prevent unauthorized access to the service, named must be configured to listen on the selected port (that is, 953 by default), and an identical key must be used by both the service and the rndc utility.
The rndc configuration is located in /etc/rndc.conf. If the file does not exist, the utility will use the key located in /etc/rndc.key, which was generated automatically during the installation process using the rndc-confgen -a command.

By far the most popular file compression utility in Linux is the gzip utility. The gzip package
is a creation of the GNU Project, in their attempt to create a free version of the original Unix
compress utility. This package includes the files.
gzip for compressing files
gzcat for displaying the contents of compressed text files
gunzip for uncompressing files
These utilities work the same way as the bzip2 utilities:
The gzip command compresses every file in the directory that matches the wildcard pattern.
The bzip2 utility
The bzip2 utility is a relatively new compression package that is gaining popularity, especially
when compressing large binary files. The utilities in the bzip2 package are:
bzip2 for compressing files
bzcat for displaying the contents of compressed text files
bunzip2 for uncompressing compressed .bz2 files
bzip2recover for attempting to recover damaged compressed files
By default, the bzip2 command attempts to compress the original file, and replaces it with the
compressed file, using the same filename with a .bz2 extension:
$ bzip2 iptables
$ ls -l iptables*
-rw-r–r– 1 buddy buddy 1477 Dec 15 16:48 iptables.bz2
