Create — Allows you to create a configuration file from scratch within the interface. The fields
•
here work similarly to those on the Upload subtab: Path is the location to which the file will be
deployed. The user, group, and mode fields allow you to set the file's ownership and permissions.
Include the actual file in the contents field. When finished, click the Create Config File button.

•

•

checkboxes and click the button matching the rank to be assigned. Subscribe with Highest Rank
will override all other config channels, except local configs. Subscribe with Lowest Rank will rank
this config channel below all others. When done, the selected systems will appear in the Systems
tab.
4.6.6.7. Configuration File Details
If you click on the name or number of a file in a list, the Configuration File Details page will appear.
You may remove the file at anytime by clicking delete file in the upper-right corner of the page. This
page contains the following tabs:
Details — General information about the file. This is the first tab you see when you click on a
•
file. It displays basic information about the file, including path, associated channel, revision, and
date. It also provides links to download, view and edit the file, as well as identify whether it is
binary. Note that files larger than 16 KB cannot be edited through the RHN website. In addition,
you can define macros (variables) here that will have different values interpolated when installed
on various systems. Refer to Section 4.6.6.8 Including Macros in your Configuration Files for a full
description of this feature.
Revisions — A list of revisions stored by RHN. You can examine revisions in the list or use the
•
Browse and Upload File buttons to upload a more recent revision.
Diff — A list of configuration files available for comparison. Click the name of the channel con-
•
taining the file, then the name of the file itself. A list of differences will appear.
Copy — A list of configuration channels that may receive a copy of the file. To copy the file to a
•
channel, select the channel's checkbox, and click the Copy File button.
Copy to Config Channel — Displays the global config channels for your organization. To copy
•
the latest revision of this file to channels, select the appropriate checkboxes, and click the Copy
File button.
Copy to System — Displays the system-specific config channels for your organization. To copy
•
the latest revision of this file to channels, select the appropriate checkboxes, and click the Copy
File button.
4.6.6.8. Including Macros in your Configuration Files
Being able to store and share identical configurations is useful, but what if you have many variations
of the same configuration file? What do you do if you have configuration files that differ only in
system-specific details, such as hostname and MAC address?
In traditional file management, you would be required to upload and distribute each file separately,
even if the distinction is nominal and the number of variations is in the hundreds or thousands. RHN
