  • SLES (12, 15)
  • CentOS (7)
  • RedHat (RHEL7, RHEL8)

For details on supported systems, check SEP sesam OS and Database Support Matrix.

Configuring RPM-based repositories

SUSE-based distributions

SUSE Linux Enterprise Server (SLES) includes the standard tool zypper which is common for package management.


  1. Add the RPM repository by using a zypper command for the relevant version (SLES12 or SLES15). Replace the <ARCHITECTURE> and <VERSION> with the appropriate values. In our example, the repository for SLES12 on x86_64 will be added.
  2. For SLES12 use:

    zypper ar https://download.sep.de/linux/SuSE/x86_64/SLES12/ SESAM

    For SLES15 use:

    zypper ar https://download.sep.de/linux/SuSE/x86_64/SLES15/ SESAM
  3. Refresh the repository cache and accept the displayed signature details.
  4. zypper refresh
    Retrieving repository 'SESAM' metadata

  5. Install SEP sesam Server or SEP sesam Client.
  6. For SEP sesam Server use:

    # zypper install sesam_srv

    For SEP sesam Client use:

    # zypper install sesam_cli

    For details, see SEP sesam Quick Install Guide.

RedHat-based distributions

RHEL-based distributions include the standard tool yum which is common for package management. RedHat Linux stores information about each repository in a separate file in the /etc/yum.repos.d directory.


  1. Create a configuration file in the /etc/yum.repos.d/sesam.repo as shown below and replace the <VERSION> and <ARCHITECTURE> with the appropriate values.
  2. [SEPSesam]
    name=SEP Sesam
  3. Refresh your yum repository:
  4. # yum updateinfo 
  5. Install any of the SEP sesam components (SEP sesam Server, Client or GUI) by using the following command:
  6. # yum install <component>

    For example, to install SEP sesam Client:

    # yum install sesam_cli

    For details, see SEP sesam Quick Install Guide.

Verifying package signatures

For manual verification, make sure the GPG key you have imported matches the fingerprint of the SEP archive key.

The fingerprint of the SEP GPG key for signatures is:

3C686930 80A255BB C9D41B40 68111EBB D273917B

Verify GPG signature via package manager

Both zypper and yum will check the repositories and RPM packages signatures during installation, so no additional steps are required.

Verify GPG signature via RPM

In case no package manager is used, the RPM packages can also be verified by using RPM only.


  1. Download the GPG public key:
  2. # curl https://download.sep.de/linux/SuSE/x86_64/SLES12/repodata/repomd.xml.key > sep.key
  3. Import the GPG key into the RPM database:
  4. # rpm --import sep.key
  5. Download the SEP sesam component and verify its signature. The following examples show how to verify the signature for SEP sesam Client depending on your Linux distribution.
  6. For RedHat use:

    # rpm -K <PACKAGE>-<VERSION>.rpm 
    sesam_cli-4.4.3-67.rhel7.x86_64.rpm: rsa sha1 (md5) pgp md5 OK

    For SUSE use:

    # rpm -v --checksig <PACKAGE>-<VERSION>.rpm
       Header V4 RSA/SHA1 Signature, key ID d273917b: OK
