2.2 Configuring Software Channels for ULN

The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.

2.2 Configuring Software Channels for ULN

Spacewalk contains a ULN plug-in for the spacewalk-repo-sync tool. The plug-in enables you to synchronize software channels without having to register the Spacewalk server with ULN.

To configure the ULN plug-in:

Change the mode of /etc/rhn/spacewalk-repo-sync/uln.conf to 600 (read-write).
```
# chmod 600 /etc/rhn/spacewalk-repo-sync/uln.conf
```
Edit /etc/rhn/spacewalk-repo-sync/uln.conf and add your SSO login user name and password for ULN:
```
[main] 
username=ULN_SSO_username 
password=ULN_SSO_password
```
Change the mode of /etc/rhn/spacewalk-repo-sync/uln.conf to 400 (read-only).
```
# chmod 400 /etc/rhn/spacewalk-repo-sync/uln.conf
```

Important

To protect your ULN credentials, verify that /etc/rhn/spacewalk-repo-sync/uln.conf is read-only (file mode 0400) by root.

# ls -l /etc/rhn/spacewalk-repo-sync/uln.conf
-r--------. 1 root root 56 Feb  2 14:44 /etc/rhn/spacewalk-repo-sync/uln.conf

When you have configured the ULN plug-in, you can use either the Spacewalk web interface, spacecmd, or spacewalk-common-channels to create the Spacewalk software channels, repositories, and activation keys:

Section 2.5, “Working with Software Channels”
Tip
Although the spacewalk-common-channels command configures software channels to access the Oracle Linux yum server, you can reconfigure the repository entries to access ULN instead. For example, if you want to use the Oracle Linux base and patch channels for an Oracle Linux release update on ULN, you can reconfigure the base software channel to access the base channel and create an additional child channel and associated repository entry for the patch channel.
See Section 2.3, “Configuring Software Channels to Obtain Packages from the Oracle Linux Yum Server”.
Section 2.4, “Working with Repositories”
Chapter 3, Creating Activation Keys

Once you have set up the software channels and repositories, download the packages by synchronizing the software channels with ULN. See Section 2.6, “Synchronizing Software Channels”.
