XVNC is the version of VNC that export the X console like Windows Terminal services. Works extremely well. For Solaris 10 X11vnc is recommended.
x11vnc allows one to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows.
It has built-in SSL encryption and authentication, UNIX account and password support, server-side scaling, single port HTTPS and VNC, mDNS service advertising, and TightVNC and UltraVNC file-transfer. It has also been extended to work with non-X devices: webcams and TV tuner capture devices, embedded Linux systems such as Qtopia Core, and natively on Mac OS X Aqua/Quartz.
It also provides an encrypted Terminal Services mode (
-svcand-xdmsvcoptions) based on Unix usernames and passwords where the user does not need to memorize his VNC display/port number.I wrote x11vnc back in 2002 because x0rfbserver was basically impossible to build on Solaris and had poor performance. The primary x0rfbserver build problems centered around esoteric
C++toolkits. x11vnc is written in plainCand needs only standard libraries and so should work on nearly all Unixes. I also added some enhancements to improve the interactive response, add many features, etc.This page and the FAQ contain a lot of information [*], solutions to many problems, and interesting applications, but nevertheless please feel free to contact me if you have problems or questions.
Please help beta test the new performance speedup feature using viewer-side pixel caching. Let me know how it goes; thanks.
Client (vnc viewer)
An x11vnc side-project provides an Enhanced TightVNC Viewer package (SSVNC) for Unix, Windows, and Mac OS X with automatic SSL and/or SSH tunnelling support, SSL Certificate creation; and on Unix: NewFBSize, ZRLE, cursor alphablending, and low color modes support. Also on Unix the UltraVNC Text Chat, Single Window, Server Input, and 1/n Scaling extensions are supported. This bundle could be placed on, say, a USB memory stick for SSL/SSH VNC viewing from nearly any networked computer.
NOTES:
Server
x11vnc server allows one to remotely view and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows. There are precompiled packages for Solaris 10 on www.sunfreeware.com (the current version is 0.9, not 0.7):
x11vnc-0.7-sol10-intel-local.gz x11vnc is a vnc server for X displays. It allows remote viewing and interaction with real X displays via keyboard and mouse - installs in /usr/local. This package also needs to have the following packages installed - zlib, jpeg, and /usr/local/lib/libgcc_s.so.1 from either libgcc-3.3 or gcc or later. You will need a vnc viewer on your client machines. I have tested the tightvnc java based viewers for Solaris and Mac OSX and will be offering a compiled version of the tightvnc vncviewer for Solaris here shortly.

The Enhanced TightVNC Viewer package is part of the x11vnc VNC server project. It provides a native VNC viewer that takes advantage of new features in x11vnc, e.g. cursor alpha blending and automatic SSL tunnelling. Some features apply to any VNC server, e.g. automatic SSH tunnelling.Another goal is to provide a package that conveniently bundles everything needed for the user to have the enhanced viewer running quickly.
This includes pre-built binaries of the viewer and utility programs for Windows and many Unix variants, and a GUI to configure and launch the viewer.
The short name for this project is "ssvnc", for SSL/SSH VNC viewer.
Release focus: Minor bugfixes
Changes:
Using port numbers lower than VNC's default port (5900) now works on Windows (for example, myhost.com:443).Author:

I also added a few enhancements to improve the interactive response, add esoteric features, etc. The FAQ contains a lot of information and solutions to problems, but please feel free to contact me if you have problems or questions.VNC (Virtual Network Computing) is a very useful network graphics protocol (applications running on one computer but displaying their windows on another) in the spirit of X, however, unlike X, the viewing-end is very simple and maintains no state. It is a remote framebuffer (RFB) protocol
Some VNC links:
For Unix, the VNC implementation includes a virtual X11 server Xvnc (usually launched via the vncserver command) that is not associated with a physical display, but provides a "fake" one X11 clients (
xterm,mozilla, etc.) can attach to. A remote user then connects to Xvnc via the VNC client vncviewer from anywhere on the network to view and interact with the whole virtual X11 desktop.The VNC protocol is in most cases better suited for remote connections with low bandwidth and high latency than is the X11 protocol (the exception is cached pixmap data on the viewing-end). Also, with no state maintained the viewing-end can crash, be rebooted, or relocated and the applications and desktop continue running. Not so with X11.
So the standard Xvnc/vncserver program is very useful, I use it for things like:
- Desktop conferencing with other users (e.g. codereviews).
- Long running apps/tasks I want to be able to view from many places.
- Motif, GNOME, and similar applications that would yield very poor performance over a high latency link.
However, sometimes one wants to connect to a real X11 display (i.e. one attached to a physical monitor, keyboard, and mouse: a Workstation or a SunRay session) from far away. Maybe you want to close down an application cleanly rather than using
kill, or want to work a bit in an already running application, or would like to help a distant colleague solve a problem with their desktop. This is where x11vnc is useful.

You will need a vnc viewer on your client machines.
