## How to Regenerate the Security Keys by Changing the Seed

You might want to change the security keys periodically or change the security keys when they have been compromised. See the Sun Management Center 3.0 Software User's Guide for more information.

This process requires you to make manual changes on the Change Manager server and on each managed host controlled by that server.

1. Choose a new seed.

2. Update the seed on the Change Manager server.

   1. Become superuser on the Change Manager server.

   2. Set the new seed:

          # /opt/SUNWsymon/sbin/es_run base-usm-seed.sh -s new_seed -u public

   3. Update the value of `agentseed` in the `/var/opt/SUNWsymon/cfg/ichange.cfg` file to match the new seed.

   4. Restart the Sun Management Center server on the Change Manager server:

          # /opt/SUNWsymon/sbin/es-restart -A

3. Update the seed on each managed host.

   1. Become superuser on the managed host.

   2. Set the new seed:

          # /opt/SUNWsymon/sbin/es_run base-usm-seed.sh -s new_seed -c agent -u public

   3. Restart the Sun Management Center agent on the managed host:

          # /opt/SUNWsymon/sbin/es-restart -A
