RealVNC http://www.realvnc.com is fully cross-platform, so a desktop running on a Linux machine may be displayed on a Windows PC, on a Solaris machine, or on any number of other architectures. There is a Windows server, allowing you to view the desktop of a remote Windows machine on any of these platforms using exactly the same viewer. RealVNC was founded by members of the AT&T team who originally developed VNC.

TightVNC http://www.tightvnc.com is an enhanced version of VNC. It has added features such as file transfer, performance improvements, and read-only password support. They have just recently included a video drive much like UltraVNC. TightVNC is still free, cross-platform (Windows Unix, and Linux), and compatible with the standard (Real) VNC.

UltraVNC http://ultravnc.com is easy to use, fast, and free VNC software that has pioneered and perfected features that the other flavors have consistently refused or been very slow to implement for cross platform and minimalist reasons. UltraVNC runs under Windows operating systems (95, 98, Me, NT4, 2000, XP, 2003). Download UltraVNC from Sourceforge's UltraVNC file list.

For Linux servers (and clients):

Most Linux distributions now include VNC Servers and Viewers and they generally can be launched from the (Gnome/KDE etc) front end; for example, with Red Hat Enterprise Linux 4 there’s VNC Server software and a choice of Viewer client software, and to launch:

Select the Remote Desktop entry in the Main Menu -> Preferences menu.

Click the Allow other users… checkbox to allow remote users to view and control your desktop.

Figure 6-27. Remote Desktop Preferences screen.

To set up a persistent VNC server on Red Hat Enterprise Linux 4:

•Set a password using vncpasswd

•Edit /etc/sysconfig/vncservers

•Enable the service with chkconfig vncserver on

•Start the service with service vncserver start
