How do I disconnect users, or prevent them connecting?¶
You can disconnect all users immediately:
...or individually from the Information Center dialog.
On the Connections page of the VNC Server Options dialog you can filter connecting users by subjecting each to a prompt:
By default, if a connecting user fails to authenticate properly five times in a row, their computer is blacklisted. You can lower this threshold for additional protection from brute-force or port scanning attacks.
