modern browsers come with a version of Java that is compatible with this
application. The Java VNC client makes a connection back to the Server
Remote Control unit over port 5900 (by default) or 15900, if encrypted.
The encrypted connection is a standard SSL (Secure Socket Layer)
encrypted link that encrypts all data from the session, including the actual
video pictures.
Because Java is considered a “safe” programming language, the Java
VNC client has some limitations. Certain special keystrokes cannot be
sent, such as “Scroll Lock” on the keyboard.
This client software requires the use of Java 2 (JRE 1.4) to enable
features like wheel mouse support. Sun Microsystems’s Java site, http://
www.java.com, is an excellent resource to ensure your browser and oper-
ating system are updated accordingly.
Native VNC Client
This system implements the VNC protocol, so any off-the-shelf VNC client
can be used.
There are several different VNC clients available, all of which should work
with this system, as the system automatically detects and makes use
of certain extensions to the basic RFB protocol as provided by the VNC
clients.
The best client currently is TightVNC (http://www.tightvnc.com). Binaries
are available for Windows, Linux, MacOS and many versions of Unix.
Source code for all clients is available there too. This version of VNC is
being actively developed.
The authoritative version of VNC is available from RealVNC (http://www.
realvnc.com). This source base is the original version of VNC, maintained
by the original developers of the standard. For a commercial, supported
version of VNC, you should consider TridiaVNC (www.tridiavnc.com).
Their version of VNC is a superset of TightVNC and contains a number of
enhancements for use in a larger corporate environment.
NOTE:
Some native VNC clients may require a flag or setting indicating
they should use BGR233 encoding by default. If this flag is not set, you
may see a garbled picture and the client will fail. The Unix versions of
