Encryption settings

The CPU IP offers a great deal of flexibility in its configuration and this extends equally to its encryption settings. Due to the variety of situations in which it might be used and the range of viewer applications that need to view it, a number of settings are available that might not make perfect sense at first glance. However, these settings should allow you to configure the CPU IP and the viewers to operate as required.

Factors to consider when setting these options might be:

Do all of the connections and operations require encryption?

Will some users be using older VNC viewer versions?

CPU IP encryption settings

The CPU IP 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

Return to host

Quits the menu and returns to the host screen.

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.

Viewer encryption settings

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four encryption settings:

Always on - This setting will ensure that the link is encrypted, regardless of the CPU IP encryption setting.

Let server choose - This setting will follow the configuration of the CPU IP. If the CPU IP has ‘Always on’ or ‘Prefer on’ set, then the link will be encrypted. If the ‘Prefer off’ setting is selected at the CPU IP, then the link will not be encrypted.

Prefer off - This setting will configure an un-encrypted link if the CPU IP will allow it, otherwise it will be encrypted.

Prefer on - If the CPU IP allows it, this setting will configure an encrypted link, otherwise it will be un-encrypted.
