5 Managing Repositories with YaST SMT Server Management

The YaST SMT Server Management module is designed to perform daily management tasks. It can be used to enable and disable the mirroring of repositories, the staging flag for repositories, and perform the mirroring and staging.

5.1 Starting SMT Management Module

SMT Management is a YaST module. There are two ways to start the module:

  • Start YaST and select Network Services, then SMT Server Management

  • Run the yast2 smt command in the terminal as root

This opens the SMT Management application window and switches to the Repositories section.

Figure 5.1: List of Repositories

5.2 Viewing and Managing Repositories

In the Repositories section, you can see the list of all available package repositories for SMT. For each repository, the list shows the repository's name, target product and architecture, mirroring and staging flag, date of last mirroring, and a short description. Sort the list by clicking the desired column header, and scroll the list items using the scrollbar on the right side.

5.2.1 Filtering Repositories

You can also filter out groups of repositories using the Repository Filter text box. Enter the desired filter term and click Filter to see only the matching entries. To cancel the current filter and display all repositories, clear the Repository Filter field and click Filter.

5.2.2 Mirroring Repositories

Before you can offer package repositories, you need to create a local mirror of their packages. To do this, follow the procedure below.

  1. From the list, select the line containing the name of the repository you want to mirror.

  2. Click the selected line to highlight it.

  3. Click the Toggle Mirroring button in the lower-left part of the window. This enables the option in the Mirroring column of the selected repository. If the repository was already selected for mirroring, clicking the Toggle Mirroring button disables the mirroring.

  4. Hit the Mirror Now button to mirror the repository.

  5. A pop-up window appears with the information about mirroring status and result.

  6. Click OK to refresh the list of repositories.

5.3 Staging Repositories

After the mirroring is finished, you can stage the mirrored repositories. In SMT, staging is a process where you create either testing or production repositories based on the mirrored ones. The testing repository helps you examine the repository and its packages before you make them available in a production environment. To make repositories available for staging, follow the steps below.

  1. From the repository list, select the line containing the name of the repository you want to manage.

  2. Click the selected line to highlight it.

  3. Click the Toggle Staging button next to the Toggle Mirroring button. This enables the option in the Staging column of the selected repository. If the repository was already selected for staging before, clicking the Toggle Staging button disables staging.

  4. Repeat steps 1 to 3 for all directories you want to stage.

Important: Toggle Staging Button Not Active

You can only stage the repositories that were previously selected for mirroring. Otherwise, the Toggle Staging button will disabled.

After you have mirrored the repositories and made them available for staging, click the Staging tab. In the upper-left part of the window, you will find the Repository Name drop-down box containing all repositories available for staging. The repository names there have the name of the attached staging group. Select the group you want to stage, and you should see a list of packages in this repository. For each patch, there is information about the patch name, its version and category, testing and production flags, and a short summary.

Next to the Repository Name drop-down box, there is a Patch Category filter. It can be used for listing only the patches that belong to one of the predefined categories.

If the selected repository allows for patch filtering, you can toggle the status flag for individual patches. This is done by clicking the Toggle Patch Status button.

Before creating a repository of packages that are available in the production environment, you need to create and test the testing repository. Select the From Full Mirror to Testing item from the Create Snapshot drop-down list. A small pop-up window appears informing you about the staging process. After the testing repository snapshot has been created, you should see the appropriate options enabled in the Testing column.

Important: Creating a Production Snapshot

After you have enabled staging for an update repository, you need to create its production snapshot to make it available to the clients. Otherwise, the clients cannot find the update repository.

Select the From Testing to Production item from the Create Snapshot drop-down box. A small pop-up window appears informing you about linking the testing repository to the production one. After the production snapshot has been created, you should see the appropriate options enabled in the Production column. Also, a green check mark appears in the Repository Name drop-down box.

5.4 Jobs and Client Status Monitoring

For each client that is registered against the SMT server, SMT creates a job queue. To use the job queue, you need to install the smt-client package on the client. During the installation of the smt-client package, a cron job is created that runs the client executable /usr/sbin/smt-agent every three hours. The agent then asks the server if it has any jobs in the queue belonging to this client and executes these jobs. When there are no more jobs in the queue, the agent terminates completely. It is important to understand that jobs are not pushed directly to the clients when they get created. They are not executed until the client asks for them at the intervals specified in the cron job. Therefore, from the time a job is created on the server until it is executed on the client, a delay of several hours may occur.

Every job can have a parent job. This means that the child job only runs after the parent job has successfully finished. It is also possible to configure advanced timing and recurrence and persistence of jobs. You can find more details about SMT jobs in Section, “smt-job”.

When creating jobs, you need to specify the GUID of the target clients using the -g GUID parameter. Although the -g parameter can be specified multiple times in a single command, you cannot use wild cards to assign a job to all clients.

Currently, the following types of jobs are available:


Run commands on the client


Open, close, or toggle the CD tray of the client


Report the status of installed patches


Reboot the client


Install packages


Install available updates

Tip: Default Job Types

By default only softwarepush, patchstatus, and update jobs are allowed. To allow more types of jobs, append the job type to the ALLOWED_AGENTS list in /etc/sysconfig/smt-client.

All clients that register against the SMT server automatically get a persistent patchstatus job added to their job queue. This is also the case for clients without the smt-clients package (SUSE Linux Enterprise 10 and older, or non-SUSE based distributions). These clients appear with the Unknown patchstatus in the client lists. The patchstatus jobs for such clients are not required, and clients can safely be deleted to clean up the output of smt-job. Keep in mind that if you update a machine to SUSE Linux Enterprise 11 or later, you need to create the patchstatus job manually.

Whenever the client runs a patchstatus job, it compares the currently installed updates with what is available in the repositories on the SMT server. The job then reports back the number of missing patches that need to be installed in each of the four categories:

  • Security

  • Package Manager

  • Recommended

  • Optional

Tip: The --agreelicense Option

To install a package and its dependencies, the job type softwarepush is used. When creating this type of job, it is a good idea to use the --agreelicense option. If a package displays a license agreement and expects it to be accepted, the job will skip the package if --agreelicense is not specified. The smt-client command forwards the installation process to zypper, which does not consider a failed acceptance of a license agreement to be an error. This results in the job being completed successfully, even if the package is not installed. Using the --agreelicense option prevents this from happening.

5.4.1 Checking the Client Status with YaST

The Clients Status section of the SMT Management window provides the status information about all the clients that use the repositories on your SMT server. This information consists of two main parts: the list of the clients and the detailed information.

You can see the client's host name, the date and time of the last network contact with the SMT server, and its update status. The update status can be one of the following:


The client packages are updated to their last version available in the production repository

Updates available

This status means that there are updates available for the client that are either optional or recommended


Either security patches or package manager patches are available for the client

Detailed information about the selected client is available in the lower part of the window. This usually includes extended status information and detailed information about the number and types of available updates.

Clients Status
Figure 5.5: Clients Status

The date and time in the Last Contact column is the last time contact of the server—even if it only ran the regular registration update script. This date is not the date of the last 'patchstatus' report. The smt-client command-line tool prints the correct date and calls it Patch Status Date. The smt-client -v command prints both dates: the patchstatus date and the last contact of the client system.

Note: Hidden Patches

Some patches may not be visible if they are required by other patches that are only shown as available after the package manager patch or patches have been installed.
