16.0 Subscription Management

Any machine running SUSE Linux Enterprise Server 11 or SUSE Linux Enterprise Desktop 11 can be configured to register against local Subscription Management Tool server to download software updates instead of communicating directly with the Novell Customer Center and the NU servers. To use an SMT server for client registration and as a local update source, you must configure the SMT server in your network first. The SMT server software is distributed as an add-on for SUSE Linux Enterprise Server and its configuration is described in the Subscription Management Tool Guide. There is no need to install any add-on on the clients to be configured for registering against an SMT server.

To register a client against an SMT server, you need to equip the client with the server's URL. As client and server communicate via the HTTPS protocol during registration, you also need to make sure the client trusts the server's certificate. In case your SMT server is set up to use the default server certificate, the CA certificate will be available on the SMT server via HTTP protocol at http://FQDN/smt.crt. In this case you do not have to concern yourself with the certificate: the registration process will automatically download the CA certificate from there, unless configured otherwise. You must enter a path to the server's CA certificate if the certificate was issued by an external certificate authority.

NOTE: Registering Against *.novell.com Subdomain

If you try to register against any *.novell.com subdomain, the certificate will not be downloaded during registration (for security reasons), and certificate handling will not be done. In such cases, use a different domain name or a plain IP address.

There are several ways to provide this information and to configure the client machine to use SMT. The first way is to provide the needed information via kernel parameters at boot time. The second way is to configure clients using an AutoYaST profile. There is also a script distributed with Subscription Management Tool, clientSetup4SMT.sh, which can be run on a client to make it register against a specified SMT server. These methods are described in the following sections:
