Configuring Desktop Sharing

In addition to the main Desktop Sharing interface shown and described above, you can also control Desktop Sharing using its control module, which you can access using the normal KDE control center, and you can also access using the Configure... on the Desktop Sharing main window. The Desktop Sharing configuration is controlled using a tabbed window, as shown in the screenshot below:


Desktop Sharing Configuration (Access Tab)

Access

The Access tab allows you configure settings related to access to the Desktop Sharing server.

The Create and Manage Invitations... takes you to the Desktop Sharing invitation management window, which was described previously.

The Announce service on the network checkbox controls whether Desktop Sharing announces invitations over the network using Service Location Protocol. This is normally a good idea, but only works really well with a Service Location Protocol aware client, such as Remote Desktop Connection.

The Allow uninvited connections checkbox controls whether Desktop Sharing allows connection without an invitation. If uninvited connections are allowed, then you should probably specify a password. You can also use the checkboxes here to choose whether you have to confirm the connection before it proceeds, and whether the person connecting can control the desktop, or only view.

If the machine is a workstation, and you choose to allow uninvited connections, you probably want to select the Confirm uninvited connections before accepting. Conversely, if the machine is a server and you are using Desktop Sharing for remote administration, you probably want to deselect Confirm uninvited connections before accepting.

Note

Desktop Sharing uses the normal RFB password system, which does not transfer your password in the clear across the network. Instead, it uses a challenge-response system. This is reasonably secure, as long as the password is securely guarded.

Session

Desktop Sharing allows you to control whether the background image is passed to the client, or not. This is controlled using a checkbox in the Session tab, as shown below.


Desktop Sharing Configuration (Session Tab)

If you check the box, Desktop Sharing will not transfer the background image. If you leave it blank, it is up to the client whether the background image is transferred or not transferred.

Network

The Network tab allows control over the port that Desktop Sharing uses, as shown below.


Desktop Sharing Configuration (Network Tab)

If you select the Assign port automatically checkbox, then Desktop Sharing will locate a suitable port, and invitations will match this port. If you deselect the Assign port automatically checkbox, you can specify a particular port. Specifying a particular port may be useful if you are using port-forwarding on the firewall. Note that if Service Location Protocol is turned on, this will automatically deal with identifying the correct port.
