If you are using Suse Linux Enterprise distribution, it is important you get your updates and patches from Novell to maintain your support and authenticity of your distribution.
Each distribution has it’s own quirks and if you have worked with a different distribution such as Red Hat, CentOS or Ubuntu, it takes a while to get around and be familiar with the updates, patches, repositories etc.
Novell has 3 distributions that may be useful for enterprise customers. Novel SLE JEOS (Suse Enterprise Linux Just Enough OS – slimmed down OS), Novell Suse Linux Enterprise (SLE) Server/Desktop and Novell Suse Linux Enterprise for VMware.
There is a new tool called zypper that lets you register and manage your updates and patch levels.
To register your product (applies to Novell Business Partners). you will have to get an activiation code. Login to your Novell site and based on your entitlements, you can obtain the registration code. Use the following command to register your SLE and refresh your zypper environment.
suse_register -a email=your_email -a regcode-sles=your_registration_code
zypper refresh
After registration list the update repositories that are added to your zypper environment.
