Can I use x11vnc to view and interact with an Xterminal (e.g. NCD) that is not running UNIX and so x11vnc cannot be run on it directly?
You can, but it will likely be very wasteful of network bandwidth since you will be polling the X display over the network as opposed to over the local hardware. To do this, run x11vnc on a UNIX machine as close as possible network-wise (e.g. same switch) to the Xterminal machine. Use the -display option to point the display to that of the Xterminal (you’ll of course need basic X11 permission to do that) and finally supply the -noshm option (this enables the polling over the network.) If the Xterminal’s X display is open to the network for connections, you might use something like “-display xterm123:0”. If you are trying to do this via an SSH tunnel (assuming you can actually ssh into the Xterminal) it will be a little tricky (either use the ssh “-R” option or consider ssh-ing in the other direction.) In all cases the X11 permissions need to allow the connection. The response will likely be sluggish (maybe only one “frame” per second.) This mode is not recommended except for “quick che
