Article ID: KB18033 KB Last Updated: 08 Mar 2017Version: 3.0
Summary:
This document describes the steps needed to change the host name of the server running the Steel-Belted Radius primary server for replication.
Symptoms:
I need to change the host name of the server running the Steel-Belted Radius primary server for replication.
Solution:
This procedure was tested using SBR 5.4 GEE running under Windows XP. Although the environment was a Windows based install, you should be able to apply similar steps in the Unix/Linux installations.

The following steps are performed on the PRIMARY server.
  1. Stop the STEEL-BELTED RADIUS service
  2. Edit the SBR_ID.XML file in the \radius\service directory. Change the host name in the XML code to reflect the new name of the server.
  3. Run the following command to demote the server to STAND ALONE mode.
    sbrsetuptool –identity SA
  4. Change the Host name via the Windows System Control panel.
  5. Reboot the server
  6. Once the server has restarted, login and stop the STEEL-BELTED RADIUS service
  7. Run the following command to promote the server back to PRIMARY mode.
    sbrsetuptool –install –path c:\radius\service –identity PRIMARY –secret <shared-secret>
  8. Start the STEEL-BELTED RADIUS service
  9. Launch the STEEL-BELTED RADIUS Admin Tool and check the REPLICATION tab. Make sure that the server is running as a PRIMARY
  10. Click the PUBLISH, and then click YES to the next dialog.


The following steps are performed on the REPLICA server(s).

  1. Stop the STEEL-BELTED RADIUS service
  2. Verify that you can ping the PRIMARY both by its host name and fully qualified domain name (FQDN). Edit the HOSTS file if necessary and change the primary’s host name to reflect its new name.
  3. Run the following command to re-register the REPLICA with the PRIMARY
    sbrsetuptool –install –path c:\radius\service –identity REPLICA –primary <name-of-primary> <IP-Address-of-Primary> <shared-secret-on-primary>
  4. Start the STEEL-BELTED RADIUS service


The following steps are performed on the PRIMARY server

  1. In the SBR Admin Tool, verify that the REPLICA has re-registered itself. This may take a minute or two to occur.
  2. Once the REPLICA is available, edit the properties and ENABLE it by checking the ENABLE checkbox. Click Save.
  3. Publish the database to the replica by clicking PUBLISH.
