VNC Connection Requiring a Password for View-only Operations
The default VNC configuration enables view-only access to the terminal
without requiring a password. This configuration requires the VNC viewer
that you copy from your terminal to a computer.
To configure a VNC connection that requires a password to view terminal
displays, follow these steps.
1. From the control panel, click Server Config.
2. On the VNC Server tab, check these items:
• View only (no remote control)
• Enable security
Security
Enable security Check this option to require password protection for VNC
connections to the terminal. Users must enter a valid
password before viewing or controlling terminal displays.
If you enable security, you must supply a password for
one of these parameters:
• Password - for control and view operations
• View-only password - for view only operations
Disabled (unchecked)
Password Specifies a password that a user must enter when
establishing a VNC connection to control terminal
displays. Select the box, then type a password in the field
at the bottom of the dialog box. The password is a
maximum of seven characters.
Password protection is required to control terminal
displays if:
• View Only is unchecked (allows control access)
• Security is enabled
No password
View-only password Specifies a password that a user must enter when
establishing a VNC connection to view terminal displays.
Select the box, then type a password in the field at the

control and view access to the terminal. With control
access enabled, you can restrict one or more users to
view-only access by providing a View-only password.

terminal displays if security is enabled:
• View Only is checked or unchecked
