Are reverse connections (i.e. the VNC server connecting to the VNC viewer) using “vncviewer -listen” and vncconnect(1) supported?
As of Mar/2004 x11vnc supports reverse connections. On Unix one starts the VNC viewer in listen mode: “vncviewer -listen” (see your documentation for Windows, etc), and then starts up x11vnc with the -connect option. To connect immediately at x11vnc startup time use the “-connect host:port” option (use commas for a list of hosts to connect to.) The “:port” is optional (default is VNC listening port is 5500.) If a file is specified instead: -connect /path/to/some/file then that file is checked periodically (about once a second) for new hosts to connect to. The -remote control option (aka -R) can also be used to do this during an active x11vnc session, e.g.: x11vnc -display :0 -R connect:hostname.domain Use the “-connect_or_exit” option to have x11vnc exit if the reverse connection fails. Also, note the “-rfbport 0” option disables TCP listening for connections (potentially useful for reverse connection mode, assuming you do not want any “forward” connections.) Note that as of Mar/2006 x
