VNC Versions

One of the earliest versions of VNC was released by AT&T. That version is no longer maintained or hosted by AT&T, but it’s available under the name RealVNC from http://www.realvnc.com. Binary versions of RealVNC are available for Windows, Linux, Solaris, and HP-UX, with source code available that will compile for other Unix-like OSs. Many Linux distributions ship with RealVNC.

Another VNC variant is available under the name TightVNC , from http://www.tightvnc.com.

TightVNC is available in binary form for Windows and Linux, with source code for other Unix-like systems also available. Many Linux distributions ship with TightVNC in addition to or ...
