Appendix A. Command Line Conﬁg Management Tools 121

When the Red Hat Network Conﬁguration Manager is run as root, it attempts to pull in needed

conﬁguration values from the Red Hat Update Agent. When run as something other than root, you

may have to make conﬁguration changes within the ~/.rhncfgrc ﬁle. The session ﬁle is cached in

~/.rhncfg-manager-session to prevent logging in for every command.

The default timeout for the Red Hat Network Conﬁguration Manager is 30 minutes. To alter this,

add the server.session_lifetime option and new value to the /etc/rhn/rhn.conf ﬁle on the

server running the manager, like so:

server.session_lifetime = 120

The Red Hat Network Conﬁguration Manager offers these primary modes: add, create-channel,

diff, diff-revisions, download-channel, get, list, list-channels, remove, remove-channel, revisions, up-

date, and upload-channel.

Each mode offers its own set of options, which can be seen by issuing the command,

rhncfg-manager mode --help, such as:

rhncfg-manager diff-revisions --help

You can see such a list of options for the add mode at Section A.2.2.1 Add Options.

A.2.1. Creating a Conﬁg Channel

To create a conﬁg channel for your organization, issue the command:

rhncfg-manager create-channel channel-label

If prompted for your RHN username and password, provide them. You should see output resembling:

Red Hat Network username: rhn-user

Password:

Creating config channel channel-label

Config channel channel-label created

Once you’ve created a conﬁg channel, you have the remaining modes available for populating and

maintaining that channel.

A.2.2. Adding Files to a Conﬁg Channel

To add a ﬁle to a conﬁg channel, you need to specify the channel label, as well as the local ﬁle to be

uploaded, such as:

rhncfg-manager add

--channel=channel-label

/path/to/file

In addition to the required channel label and path to the ﬁle, you may use the available options for

modifying the ﬁle during its addition. For instance, you may alter the path and ﬁlename by including

the --dest-file option in the command, like:

rhncfg-manager add

--channel=channel-label

--dest-file=/new/path/to/file.txt

/path/to/file

You should see output resembling:

1 2 ... 128 129 130 131 132 133 134 135 136 137 138 ... 197 198
