FreeBSD VNC Viewer Server Listener
=======================================

1. VNC Viewer to connect to desktop of a vnc server
2. VNC Server to share your desktop with a vnc viewer
3. VNC Server to share your desktop by initiating a reverse vnc connection
4. VNC Listening Viewer to accept a reverse connection from a vnc server


=======================================
1. VNC Viewer
---------------------------------------

KDE Plasma comes with Krdc.
Launch Krdc and connect to a vnc server.
- can transfer files
- supports vnc and rdp

Krdc issues:
- No ability to view secondary display
- Broken fit to window can be fixed with: Settings > Configure Toolbars... ADD Scaling Factor


=======================================
2. VNC Server
---------------------------------------

KDE Plasma comes with Krfb.
Launch Krfb and connect from a vnc viewer.

Krfb issues:
- No ability to share secondary display
- No ability to initiate a reverse connection


=======================================
3. VNC Server to initiate a reverse connection
---------------------------------------

Good luck. Please share your successes.

=======================================
4. VNC Listening Viewer (Reverse VNC)
---------------------------------------

The only listening viewers available on FreeBSD are TightVNC and the fork TigerVNC-viewer.
These are only available to be installed from ports.

Common issues:
- No ability to scale the server
- No ability to do remote file transfers

TightVNC issues:
- Taking a screenshot using spectacle will drop ALL connections (not nice)
    CleanupXtErrorHandler called
    Error: Event with wrong window
- Typing ctrl-c to copy or ctrl-v to paste from the viewer will drop the connection (not nice)
- Typing ctrl-v to paste from the server will drop the connection (not nice)
- Scrollbar widgets are from the 1970s and scrolling is a joke

TigerVNC issues:
- No ability to accept multiple simultaneous connections (show stopper for me)
- Will crash as soon as a server disconnects
- Scrollbar widgets are from the 1980s

---------------------------------------
Prepare ports and install tightvnc as the better choice.

root@local:~ # cd /usr/ports/net/tightvnc
root@local:~ # make install

Run the vnc listening viewer and connect from a vnc server reverse connection.
user@local:~ $ vncviewer -listen

---------------------------------------
Reverse connect the vnc server to the listening viewer address.

Windows users can use TightVNC Server "Attach Listening Viewer".
Linux users might try x11vnc.
user@remote:~ $ x11vnc -connect address.of.listening.viewer
