Configuring VNC Viewer before you connect

In most circumstances, VNC Viewer is ready to connect to VNC Server out-of-the-box. You do not need to configure it. Carry on from Connecting to a host computer.

However, you must configure VNC Viewer before you connect in the following circumstances:

•  Your client computer is protected by a proxy server. See Connecting via a proxy server.

•  VNC Server mandates the single sign-on authentication mechanism but you do not want to authenticate as the user you logged on to the client computer as. See Disabling single sign-on.

•  You want to specify printing options. See Configuring printing.

To configure VNC Viewer before you connect, click the Options button at the bottom of the VNC Viewer dialog. More on this dialog. The VNC Viewer - Options dialog opens:

(In this picture, the dialog is in Advanced mode.)

Note that the Connection and Printing tabs are not available after you connect. More on this dialog.

Connecting via a proxy server

If your client computer is protected by a proxy server, you must tell VNC Viewer about that proxy server. On the Connection tab, choose:

•  Use Microsoft Internet Explorer proxy settings if this browser has already been provisioned with proxy server information. Note this option has a different name under UNIX/Linux and Mac OS X.

•  Use these proxy settings to specify the network address of either an HTTP or a SOCKS 5 proxy server, and a port on which an appropriate application or process is listening, separated by a colon.

If the proxy server is protected by BASIC or DIGEST authentication, enter a user name and password in the appropriate boxes.

Disabling single sign-on

Note: The information in this section applies to VNC Viewer for Windows and Mac OS X, for connections to VNC Server (Enterprise) only.

By default, if VNC Server (Enterprise) specifies single sign-on as its authentication mechanism, then you may be able to connect without supplying a user name and password. This is because you have already successfully authenticated to a network when logging on to your client computer. For more information, see Authenticating automatically using client computer user credentials.

You can disable this feature if you want to connect to VNC Server using the credentials of a different user. This might give you access to more VNC features while the connection is in progress. To do this, turn off Use single sign-on if VNC Server supports it on the Connection tab.

Configuring printing

By default, when you connect to VNC Server (Enterprise) or VNC Server (Personal), your client computer’s default printer (if it has one) is shared with the host computer and made its default while the connection is in progress. This means you can print host computer files directly to your local printer. For more information about this feature, see Printing host computer files to a local printer.

You can print but choose not to change the host computer’s default printer. This means you will have to explicitly select your printer when you print. To do this, turn off Make it the default printer on VNC Server on the Printing tab.

To disable printing, choose Don’t share a printer.
