RFB Protocol

aka VNC


Version 2.2 adds support for VNC connections with the desktop mode.


To listen for RFB / VNC connections on a specific port use:

xpra start-desktop --start=xterm --bind-rfb=

(5900 is the default port for VNC servers)

Alternatively, you can start a session with a TCP socket and it will be upgraded to RFB when required by the client:

xpra start-desktop --start=xterm --bind-tcp=


You should be able to connect using any VNC compliant client. ie:

vncviewer host

Note: this mode is sub-optimal, use the xpra native protocol for better performance and features.
