Getting my head around websockify/noVNC

[Dave Thomas]

Sorry for such a stupid question, but here's what I want to do:

x11vnc server running on machine 1.

Desktop viewable from other machines on same internal network using web browser

I like to avoid running anything additional on the machine 1 (the one with x11vnc server).  Is it possible, like running websockify running on machine 2 (windows)?

I've installed websockify (and noVnc) on my windows desktop (machine 2).  Machine 2 can currently view machine 1 desktop using a vncviewer.  But, when I run websockify speciying machine 1 ip as source, I get a complaint:

C:\>websockify 192.168.50.100:5900 127.0.0.1:6000

WARNING: no 'resource' module, daemonizing is disabled

WebSocket server settings:

  - No SSL/TLS support (no cert file)

    sock.bind(addrs[0][4])

OSError: [WinError 10049] The requested address is not valid in its context

Do I have to run websockify on machine #1 (where the x11vnc server is running), or am I just invoking websockify incorrectly?

Thanks!

Maybe I just have target and source IPs confused?  When I switch them, I see this:

C:\websockify-master>websockify 127.0.0.1:6000 192.168.50.100:5900

WARNING: no 'resource' module, daemonizing is disabled

WebSocket server settings:

  - Listen on 127.0.0.1:6000

  - No SSL/TLS support (no cert file)

  - proxying from 127.0.0.1:6000 to 192.168.50.100:5900

But, when I use a Chrome browser pointing to the novnc html, it just hangs.

Hello,

It looks to me like your missing the NoVNC web server in your websockify command. So for me I have in my root C drive a fodler for NoVNC and in there i have the NoVNC-web and Websockify-master folders. I then invoke websockify like this:

C:\websockify-master>websockify :8080 192.168.50.100:5900 --web C:\NoVNC\NoVNC-web

I don't specify my host server IP, just the port. And result (keep in mind i am using tokens instead of VNC Server IP in picture below, but should look like this:

Regards!
