@mkk i have run a tigervnc server on one machine, accessing the session from another machine using a vnc viewer, placing wires works fine. I also tried tunnelling X thru a ssh connection and this works fine as well. I was trying now to access the vnc session from inside a browser using novnc (--> https://novnc.com/noVNC/vnc.html ) The browser shows a Connect button, however there is no way to tell the novnc client where to connect to, and i found no info anywhere on how to tell novnc the server address. [Edit] I have read i need to run a websocket proxy that points to the vncserver address, run the novnc web page and connect. But this is little beyond my knowledge.
