Encryption

Three encryption options are available; Always on, Prefer off, Prefer on. The one to choose depends on the specific details of your installation. The use of encryption imposes a slight performance overhead of roughly 10% but is highly secure against third party intrusion.

Encryption settings

The Unit configuration page offers three encryption settings:

Always on - This setting will force all viewers to use encryption. Note: This setting will preclude any VNC viewer versions that do not support encryption.

Prefer off - This setting does not enforce encryption unless a viewer specifically requests it. If a viewer has its ‘Let server choose’ setting, then an un-encrypted link will be set up.

Prefer on - This setting generally enforces encryption unless an earlier viewer version is unable to support it, in which case the link will be un-encrypted. If a viewer has its ‘Let server choose’ setting, then the link will be encrypted.

Unit Advanced Configuration

The “Advanced Configuration” tab will display advanced options that generally do not need modifying.

Force VNC protocol 3.3

IMPORTANT: The use of this option is not recommended. VNC protocol 3.3 is a legacy version that does not offer any encryption.

Idle timeout

Determines the period of inactivity on a remote connection before the user is logged out. The idle timeout period can be set to any time span, expressed in minutes. Note: The Screensaver option serves a similar purpose for local connections. A value of 0 will disable the timeout.

Protocol timeout

Sets the time period by which responses should have been received to outgoing data packets. If the stated period is exceeded, then a connection is considered lost and terminated.
