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 a system’s configuration files: the
Red Hat Network
Configuration Client
and the
Red Hat Network Configuration Manager
. There is a
complementary
Red Hat Network Actions Control
tool that is used to enable and dis-
able configuration management on client systems. If you do not yet have these these tools
installed, they can be found within the
RHN Tools
child channel for your operating system.
Tip
Keep in mind, whenever a configuration file is deployed via RHN, a backup of the previous
file including its full path is made in the
/var/lib/rhncfg/backups/
directory on the
affected system. The backup retains its filename but has a
.rhn-cfg-backup
extension
appended.
A.1. Red Hat Network Actions Control
The
Red Hat Network Actions Control
(
rhn-actions-control
) application is used
to enable and disable configuration management of a system. Client systems cannot be
managed in this fashion by default. This tool allows Organization Administrators to en-
able or disable specific modes of allowable actions such as:
deploying
a configuration
file onto the system,
uploading
a file from the system,
diffing
what is currently man-
aged on a system and what is available, or allowing running arbitrary
remote commands
.
These various modes are enabled/disabled by placing/removing files and directories in the
/etc/sysconfig/rhn/allowed-actions/
directory. Due to the default permissions
on the
/etc/sysconfig/rhn/
directory, RHN Actions Control will most likely have to
be run by someone with root access.
A.1.1. General command line options
There is a
man
page available, as there are for most command line tools, though the use
of this tool is simple enough to describe here briefly. Simply decide what RHN scheduled
actions should be enabled for use by system administrators. The following options enable
the various scheduled action modes:
