The CommuniGate Pro is designed as a highly secure application. In order to perform certain operations, the Server runs as root on Unix platforms, and it carefully checks that no user can access restricted OS resources via the Server. Since many other servers do not provide the same level of security, system administrators preferred to run servers in a non-root mode, so a hole in the server security would not allow an intruder to access the restricted OS resources.
CommuniGate Pro can "drop" the root privilege. The privilege can be dropped in the "permanent" or "reversible" mode. When asked to drop the root (uid=0) privilege, the Server changes its UID:
When the root privilege is dropped, the following restrictions apply:
If the root privilege was dropped in the "reversible" mode, the root privilege can be restored. For example, if you need to open a listener on the port 576, but the Server root privilege has been dropped, you should restore the root privilege first, then open the listener port, and then you can drop the Root privilege again.
To drop the root privilege permanently, use a special Command Line Option.
To drop the root privilege in the "reversible" mode, click the "Drop Root" button on the General page. The button should change to the "Restore Root" button - you can use it to restore the Server root privilege. This option is not available on those platforms that cannot drop the root privilege correctly (Linux).
