8.0 Configuring Clients to Use SMT

Any machine running SUSE Linux Enterprise 10 SP4 or 11 SP1 (or later) can be configured to register against SMT and download software updates from there, instead of communicating directly with the Customer Center and the NU servers.

If your network includes an SMT server to provide a local update source, 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 you set up your SMT server to use the default server certificate, the CA certificate will be available on the SMT server at http://FQDN/smt.crt . In this case you do not have to manually set 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 a case, use a different domain name or a plain IP address.

There are several ways to provide the registration information and to configure the client machine to use SMT:

  1. Provide the needed information via kernel parameters at boot time (Section 8.1, Using Kernel Parameters to Access an SMT Server).

  2. Configure the clients using an AutoYaST profile (Section 8.2, Configuring Clients with AutoYaST Profile).

  3. Use the clientSetup4SMT.sh script (Section 8.3, Configuring Clients with the clientSetup4SMT.sh Script in SLE 11). This script can be run on a client to make it register against a specified SMT server.

  4. In SUSE Linux Enterprise 11 you can now set the SMT server URL with the YaST registration module during installation (Section 8.4, Configuring Clients with YaST).

These methods are described in the following sections.
