5.5 Channels and Packages
A channel is a list of Red Hat Linux packages. Channels are used to choose packages to be installed
in the
Channels and Packages section of Software Manager .
There are two types of channels: base channels and child channels. A base channel consists of a list of
packages based on a specific architecture and Red Hat Linux release. For example, all the packages in
Red Hat Linux 7.1 for the x86 architecture is a base channel. The list of packages in Red Hat Linux 7.1
for the Itanium architecture is a different base channel. A child channel is a channel associated with
a base channel but contains extra packages. For example, an organization can create a child channel
that is associated with the Red Hat Linux 7.1 for the x86 architecture and that contains extra packages
needed only for the organization, such as a custom engineering application.
5.5.1 Channel List
The
Channel List
page provides a list of all base channels and their child channels. To view a list
of individual packages in a channel, click on the name of the channel (base or child). You will be
presented with a list of packages in the channel in groups of 20. Click
Next to see the next group of
packages. Click
Prev
to see the previous group of packages.
If you are looking for a specific package or a subset of packages, you can use the package filter on the
top of the list. Enter a substring to search for. It will search all the packages in the list for the substring
at the beginning, in the middle, or at the end of the package name. The filter is case-insensitive. For
example, typing
ks
in the filter might return all the
ksconfig
,
krb5-workstation
, and
links
.
You can also use this list to select packages and add them to your current selections list. To do so, click
the checkbox beside the package name and under the
Select column. Click .
To download packages, select the packages and click the Download Selected Packages button. Refer
to Section 5.5.5, Package Download for details.
