Configuring the system
2.5 Description of the actions
This command deletes all of the SSH keys preinstalled by Siemens on the control system.
When called from the service system, the key on the CompactFlash Card is involved, and not
the SSH keys on the service system itself.
NOTICE
Accessing the control
When removing the SSH key preinstalled by Siemens, then the risk of unauthorized access
using it is eliminated, assuming this is known.
However, in order to ensure sufficient access to the system, before deleting we recommend
that a new SSH key is defined and installed.

Principle of operation
This command closes a port in the firewall opened previously with the "sc openport" command.
This is only necessary when the port is to be closed manually before the time set with "sc
openport" expires. Otherwise the port is closed automatically when the port service life expires.
One parameter is the ID number of the firewall rule output by "sc openport".
