Command Line Config Management Tools
In addition to the options provided in the RHN website, Red Hat Network offers two command line
tools for managing configuration files: the
Red Hat Network Configuration Client
and the
Red Hat
Network Configuration Manager
. If you don’t yet have these these tools installed, they can be found
within the RHN Provisioning child channel for your operating system.
A.1. Red Hat Network Configuration Client
As the name implies, the
Red Hat Network Configuration Client
(
rhncfg-client
) is to be in-
stalled and run from an individual client system. From there you may use it to gain knowledge about
how RHN will deploy configuration files to the particular system.
The
Red Hat Network Configuration Client
offers these primary modes: list, get, channels, diff,
and verify.
A.1.1. Listing Config Files
To list the configuration files for the machine and the labels of the config channels containing them,
issue the command:

A.1.2. Getting a Config File
To download the most relevant configuration file for the machine, issue the command:
rhncfg-client get /etc/foo.txt
You should see output resembling:

upon the rank of the config channel containing it. This is accomplished within the
Configuration
tab
of the

page. Refer to Section 4.4.2.6
