The initial versions of the XRDP project relied on a local VNC server installation that had to be present alongside the program, in order to relay the graphics and controls between the user and the server [7] (known as the "VNC forwarding mode"). However, this mode is currently not recommended to use anymore, due to its slow performance.
x11vnc is a Virtual Network Computing (VNC) server program. It allows remote access from a remote client to a computer hosting an X Window session and the x11vnc software, continuously polling [ 4 ] the X server's frame buffer for changes.
File transfer: the software allows the user to transfer files between the local and remote computers, from within the client software's user interface. Audio support: the remote control software transfers audio signals across the network and plays the audio through the speakers attached to the local computer. For example, music playback ...
Alternatively, a machine (which may be a workstation or a network server) with screen, keyboard, and mouse can be set up to boot and run the VNC server as a service or daemon, then the screen, keyboard, and mouse can be removed and the machine stored in an out-of-the way location. Users commonly deploy VNC as a cross-platform remote desktop system.
When packages are being installed, debconf asks the user questions which determine the contents of the system-wide configuration files associated with that package. After package installation, it is possible to go back and change the configuration of a package by using the dpkg-reconfigure program, or another program such as Synaptic .
Vinca relies on x11vnc to call the final reverse connection, after checking and diagnosing network and destination availability. Supports any Unix operating system with x11vnc (version 0.6 or newer) and has been distributed with extra repositories for Debian (since version 3.1 sarge) and Ubuntu (since version 4.10 warty).
In the X Window System, programs run as X clients, and as such they connect to the X display server, possibly via a computer network. Since the network may be accessible to other users , a method for forbidding access to programs run by users different from the one who is logged in is necessary.
The communication protocol between server and client operates network-transparently: the client and server may run on the same machine or on different ones, possibly with different architectures and operating systems. A client and server can even communicate securely over the Internet by tunneling the connection over an encrypted network session.
