Configuration of host-pcVNC CommunicationVNC Server Parameters

 

Because there is such a great variety of VNC server applications, we can only give a general overview of the configuration of the VNC server. We base this on the RealVNC server application.

 

VNC server address:



Usually, the various servers offer one or more options of identifying the address under which they can be contacted in the network.

Below is an example using the RealVNC server

In WinXP RealVNC-Server-IP or RealVNC-Server-IPWin7in Win7

 

Hinweis

The target address of the Host PC must be located in the same network as that of the Thin Client or must be contactable from there.

Ports:


Accept connections on port

Defines a specific port on the server connection for data transfer. Usually this is Port 5900. If network conflicts or other reasons cause you to use a different port, you need to explicitly call this up in the Configuration.


Serve Java viewer on port

For Web browser connection. Not applicable here.

VNC Password:


The various VNC server applications all use passwords to authenticate someone requesting a VNC connection. The passwords can have different origins.

None

This password option defines no password. The VNC server on the Host PC permits every Remote PC (Thin Client) requesting a VNC connection via its address access to the system.

VNC Password

This password option defines one or, depending on the VNC server application, several passwords via which the VNC server of the Host PC requests authentication from the Remote PC.

Windows Password

This option uses Window's own access authentication. With this, the VNC server of the Host PC permits the Remote PC access to the Host PC according to the access criteria defined by the VNC server.

Single sign on

This option uses Window's own access authentication as well as an additional authentication via a Windows-based log-in. With this, the VNC server of the Host PC permits the Remote PC access to the Host PC according to the access criteria defined by the VNC server, provided the user has authenticated himself or herself with a Windows log-in valid for the Host PC.

Encryption:


Most VNC servers use certain process for the transfer of image, mouse and keyboard data to protect these from unauthorised access.


Always on

Determines that data is always encrypted.


Prefer on

Determines that data is always encrypted unless the Thin Client requests no encryption. This is necessary when the Configuration requests no encryption as a standard.


Prefer off

Determines that data is never encrypted unless the Thin Client requests encryption. This is necessary when the Configuration requests encryption.

Prompt local user to accept connections


Server-specific option allowing the user of the Host PC to acknowledge or refuse a connection request. This and other options are probably less relevant to typical applications, as usually the Host PC is used for direct Remote access.

Start VNC Server automatically with windows


Option determining that the service of the VNC server is activated automatically when Windows is started. This option should usually be selected, as otherwise the Remote access function (of the VNC servers) would have to be started explicitly after a Host PC system start.

 

Hinweis

For further information, please refer to the manual of the VNC server or contact your network administrator.
