| About TigerVNC |
| ============== |
| |
| Virtual Network Computing (VNC) is a remote display system which allows you to |
| view and interact with a virtual desktop environment that is running on another |
| computer on the network. Using VNC, you can run graphical applications on a |
| remote machine and send only the display from these applications to your local |
| machine. VNC is platform-independent and supports a wide variety of operating |
| systems and architectures as both servers and clients. |
| |
| TigerVNC is a high-speed version of VNC based on the RealVNC 4 and X.org code |
| bases. TigerVNC started as a next-generation development effort for TightVNC |
| on Unix and Linux platforms, but it split from its parent project in early 2009 |
| so that TightVNC could focus on Windows platforms. TigerVNC supports a variant |
| of Tight encoding that is greatly accelerated by the use of the libjpeg-turbo |
| JPEG codec. |

| |
| All Platforms |
| ============= |
| |
| All versions of TigerVNC contain the following programs: |
| |
| * vncviewer - the cross-platform TigerVNC Viewer, written using FLTK. |
| vncviewer connects to a VNC server and allows you to interact |
| with the remote desktop being displayed by the VNC server. The |
| VNC server can be running on a Windows or a Unix/Linux machine. |
| |
| |
| Windows-Specific |
| ================ |
| |
| The Windows version of TigerVNC contains the following programs: |
| |
| * winvnc - the TigerVNC Server for Windows. winvnc allows a Windows desktop to |
| be accessed remotely using a VNC viewer. |
| |
| winvnc may not work if the Fast User Switching or Remote Desktop features are |
| in use. |
| |
| |
| Unix/Linux-Specific (not Mac) |
| ============================= |
| |
| The Unix/Linux version of TigerVNC contains the following programs: |
| |
| * Xvnc - the TigerVNC Server for Unix. Xvnc is both a VNC server and an X |
| server with a "virtual" framebuffer. You should normally use the |
| vncserver script to start Xvnc. |
| |
| * vncserver - a wrapper script which makes starting Xvnc more convenient. |
| vncserver requires Perl. |
| |
| * vncpasswd - a program which allows you to change the VNC password used to |
| access your VNC server sessions (assuming that VNC authentication |
| is being used.) The vncserver script will automatically launch |
| this program if it detects that VNC authentication is in use and |
| a VNC password has not yet been configured. |
| |
| * vncconfig - a program which is used to configure and control a running |
| instance of Xvnc. |
| |
| * x0vncserver - an inefficient VNC server which continuously polls any X |
| display, allowing it to be controlled via VNC. It is intended |
| mainly as a demonstration of a simple VNC server. |
