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.
However, it is possible to use Xvnc or Xvfb to create a 'virtual' extra display, and have x11vnc connect to it, enabling X-11 access to headless servers. [5] x11vnc has security features that allows the user to set an access password or to use Unix usernames and passwords. It also has options for connection via a secure SSL link. [4]
NAT passthrough: the ability to connect to the server behind a NAT without configuring the router's port forwarding rules. It offers an advantage when you can't reconfigure the router/firewall (for example in case it is on the Internet service provider's side), but is a serious security risk (unless the traffic is end-to-end encrypted), because ...
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).
Workarounds like x11vnc (VNC :0 viewers), Xpra's shadow mode and NX's nxagent shadow mode also exist to make the current X-server screen available. This ability allows the user interface (mouse, keyboard, monitor) of a running application to be switched from one location to another without stopping and restarting the application.
Remmina is in the package repositories for Debian versions 6 (Squeeze) and later and for Ubuntu versions since 10.04 (Lucid Lynx). [6] [7] As of 11.04 (Natty Narwhal), it replaced tsclient as Ubuntu's default remote desktop client. [8] [9] The FreeBSD ports/package collection also contains it as a separate port and additional protocol-specific ...
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. [9] A display server using the Wayland protocol is called a Wayland compositor, because it additionally performs the task of a compositing window manager.
Xvfb is also used for remote control. VNC over SSH can be faster than X11 over SSH, [4] specially reducing latency over the internet. [5] In this case, Xvfb is often combined with a lightweight window manager (such as Fluxbox or Openbox) and a VNC server such as X11vnc.
