* To encrypt the traffic using the WebSocket 'wss://' URI scheme you
|
||||
need to generate a certificate for the proxy to load. By default the
|
||||
proxy loads a certificate file name `self.pem` but the `--cert=CERT`
|
||||
option can override the file name. You can generate a self-signed
|
||||
certificate using openssl. When asked for the common name, use the
|
||||
hostname of the server where the proxy will be running:
|
||||
|
||||
`openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem`
|
||||
|
||||
* `tightvnc` provide a nice startup script that can be used to run
|
||||
a separate X desktop that is served by VNC. To install and run the
|
||||
server under Ubuntu you would do something like this:
|
||||
|
||||
`sudo apt-get install tightvncserver`
|
||||
|
||||
`vncserver :1`
|
||||
|
||||
The VNC server will run in the background. The port that it runs
|
||||
on is the display number + 5900 (i.e. 5901 in the case above).
|
||||
|
||||
* `x11vnc` can be used to share your current X desktop. Note that if
|
||||
you run noVNC on the X desktop you are connecting to via VNC you
|
||||
will get a neat hall of mirrors effect, but the the client and
|
||||
server will fight over the mouse.
|
||||
|
||||
`sudo apt-get install x11vnc`
|
||||
|
||||
`x11vnc -forever -display :0`
|
||||
|
||||
Without the `-forever` option, x11vnc will exit after the first
|
||||
disconnect. The `-display` option indicates the exiting X display to
|
||||
share. The port that it runs on is the display number + 5900 (i.e.
|
||||
5900 in the case above).
|
||||
|
||||
* To run the python proxy directly without using launch script (to
|
||||
pass additional options for example):
|
||||
|
||||
`./utils/websockify source_port target_addr:target_port`
|
||||
|
||||
`./utils/websockify 8787 localhost:5901`
|
||||
|
||||
* To activate the mini-webserver in websockify use the `--web DIR`
|
||||
option:
|
||||
|
||||
`./utils/websockify --web ./ 8787 localhost:5901`
|
||||
|
||||
|
||||
* Point your web browser at http://localhost:8787/vnc.html. On the
|
||||
page enter the location where the proxy is running (localhost and
|
||||
8787) and the password that the vnc server is using (if any). Hit
|
||||
the Connect button.
|
||||
|
||||
* If you are using python 2.3 or 2.4 and you want websockify to
|
||||
support 'wss://' (TLS) then see the
|
||||
[websockify README](http://github.com/kanaka/websockify/blob/master/README.md)
|
||||
for instructions on building the ssl module.

noVNC is designed to be easily integrated into existing web sites with
|
||||
the existing structure and styling.
|
||||
|
||||
At a minimum you must include the `vnc.js` and `ui.js` scripts and then call
|
||||
UI.load(). For example:
|
||||
|
||||
<head>
|
||||
<script src='include/vnc.js'></script>
|
||||
<script src="include/ui.js"></script>
|
||||
</head>
|
||||
<body>
|
||||
<div id='vnc'>Loading</div>
|
||||
|
||||
<script>
|
||||
window.onload = function () {
|
||||
UI.load('vnc');
|
||||
}
|
||||
</script>
|
||||
</body>
|
||||
|
||||
See `vnc.html` and `vnc_auto.html` for examples. The file
|
||||
`include/plain.css` has a list of stylable elements.
|
||||
|
||||
The `vnc.js` also includes other scripts within the `include`
|
||||
sub-directory. The `VNC_uri_prefix` variable can be use override the
|
||||
URL path to the `include` sub-directory.

You will need console logging support in the browser. Recent Chrome
|
||||
and Opera versions have built in support. Firefox has a nice extension
|
||||
called "firebug" that gives console logging support.
|
||||
|
||||
First, load the noVNC page with `logging=debug` added to the query string.
|
||||
For example `vnc.html?logging=debug`.
|
||||
|
||||
Then, activate the console logger in your browser. With Chrome it can
|
||||
be activate using Ctrl+Shift+J and then switching to the "Console"
|
||||
tab. With firefox+firebug, it can be activated using Ctrl+F12.
|
||||
|
||||
Now reproduce the problem. The console log output will give more
|
||||
information about what is going wrong and where in the code the
|
||||
problem is located.
|
||||
|
||||
If you file a issue/bug, it is very helpful for me to have the last
|
||||
page of console output leading up the problem in the issue report.
|
||||
Other helpful issue/bug information: browser version, OS version,
|
||||
noVNC git version, and VNC server name/version.
