## noVNC: HTML5 VNC Client
|
||||
## websockify: WebSockets support for any application/server
|
||||
|
||||
websockify was formerly named `wsproxy` and was part of the
|
||||
[noVNC](https://github.com/kanaka/noVNC) project.
|
||||
|
||||
At the most basic level, websockify just translates WebSockets traffic
|
||||
to normal socket traffic. websockify accepts the WebSockets handshake,
|
||||
parses it, and then begins forwarding traffic between the client and
|
||||
the target in both directions. WebSockets payload data is UTF-8
|
||||
encoded so in order to transport binary data it must use an encoding
|
||||
that can be encapsulated within UTF-8. websockify uses base64 to encode
|
||||
all traffic to and from the client. Also, WebSockets traffic starts
|
||||
with '\0' (0) and ends with '\xff' (255). Some buffering is done in
|
||||
case the data from the client is not a full WebSockets frame (i.e.
|
||||
does not end in 255).
|
||||
|
||||
|
||||
### Additional websockify features
|
||||
|
||||
These are not necessary for the basic operation.
|
||||
|
||||
* Daemonizing: When the `-D` option is specified, websockify runs
|
||||
in the background as a daemon process.
|
||||
|
||||
* SSL (the wss:// WebSockets URI): This is detected automatically by
|
||||
websockify by sniffing the first byte sent from the client and then
|
||||
wrapping the socket if the data starts with '\x16' or '\x80'
|
||||
(indicating SSL).
|
||||
|
||||
* Flash security policy: websockify detects flash security policy
|
||||
requests (again by sniffing the first packet) and answers with an
|
||||
appropriate flash security policy response (and then closes the
|
||||
port). This means no separate flash security policy server is needed
|
||||
for supporting the flash WebSockets fallback emulator.
|
||||
|
||||
* Session recording: This feature that allows recording of the traffic
|
||||
sent and received from the client to a file using the `--record`
|
||||
option.
|
||||
|
||||
* Mini-webserver: websockify can detect and respond to normal web
|
||||
requests on the same port as the WebSockets proxy and Flash security
|
||||
policy. This functionality is activate with the `--web DIR` option
|
||||
where DIR is the root of the web directory to serve.
|
||||
|
||||
* Wrap a program: see the "Wrap a Program" section below.
|
||||
|
||||
|
||||
### Implementations of websockify
|
||||
|
||||
The primary implementation of websockify is in python. There are two
|
||||
other implementations of websockify in C, and Node (node.js) in the
|
||||
`other` directory.
|
||||
|
||||
Here is the feature support matrix for the the websockify
|
||||
implementations:

### Description
|
||||
* Note 1: to use SSL/wss with python 2.5 or older, see the following
|
||||
section on *Building the Python ssl module*.
|
||||
|
||||
noVNC is a VNC client implemented using HTML5 technologies,
|
||||
specifically Canvas and WebSockets (supports 'wss://' encryption).
|
||||
noVNC is licensed under the
|
||||
[LGPLv3](http://www.gnu.org/licenses/lgpl.html).
|
||||
|
||||
Special thanks to [Sentry Data Systems](http://www.sentryds.com) for
|
||||
sponsoring ongoing development of this project (and for employing me).

||||
### Wrap a Program
|
||||
|
||||
Notable commits, announcements and news are posted to
|
||||
@<a href="http://www.twitter.com/noVNC">noVNC</a>
|
||||
In addition to proxying from a source address to a target address
|
||||
(which may be on a different system), websockify has the ability to
|
||||
launch a program on the local system and proxy WebSockets traffic to
|
||||
a normal TCP port owned/bound by the program.
|
||||
|
||||
The is accomplished with a small LD_PRELOAD library (`rebind.so`)
|
||||
which intercepts bind() system calls by the program. The specified
|
||||
port is moved to a new localhost/loopback free high port. websockify
|
||||
then proxies WebSockets traffic directed to the original port to the
|
||||
new (moved) port of the program.
|
||||
|
||||
### Screenshots
|
||||
The program wrap mode is invoked by replacing the target with `--`
|
||||
followed by the program command line to wrap.
|
||||
|
||||
Running in Chrome before and after connecting:
|
||||
`./websockify 2023 -- PROGRAM ARGS`
|
||||
|
||||
<img src="http://kanaka.github.com/noVNC/img/noVNC-1.jpg" width=400> <img src="http://kanaka.github.com/noVNC/img/noVNC-2.jpg" width=400>
|
||||
The `--wrap-mode` option can be used to indicate what action to take
|
||||
when the wrapped program exits or daemonizes.
|
||||
|
||||
See more screenshots <a href="http://kanaka.github.com/noVNC/screenshots.html">here</a>.
|
||||
Here is an example of using websockify to wrap the vncserver command
|
||||
(which backgrounds itself) for use with
|
||||
[noVNC](https://github.com/kanaka/noVNC):
|
||||
|
||||
`./websockify 5901 --wrap-mode=ignore -- vncserver -geometry 1024x768 :1`
|
||||
|
||||
### Projects/Companies using noVNC
|
||||
Here is an example of wrapping telnetd (from krb5-telnetd).telnetd
|
||||
exits after the connection closes so the wrap mode is set to respawn
|
||||
the command:
|
||||
|
||||
* [Sentry Data Systems](http://www.sentryds.com): uses noVNC in the
|
||||
[Datanex Cloud Computing Platform](http://www.sentryds.com/products/datanex/).
|
||||
`sudo ./websockify 2023 --wrap-mode=respawn -- telnetd -debug 2023`
|
||||
|
||||
* [Ganeti Web Manager](http://code.osuosl.org/projects/ganeti-webmgr):
|
||||
Feature [#1935](http://code.osuosl.org/issues/1935).
|
||||
The `wstelnet.html` page demonstrates a simple WebSockets based telnet
|
||||
client.
|
||||
|
||||

|
||||
|
||||
* [openQRM](http://www.openqrm.com/): VNC plugin available
|
||||
by request. Probably included in [version
|
||||
4.8](http://www.openqrm.com/?q=node/15). [Video
|
||||

|
||||
### Building the Python ssl module (for python 2.5 and older)
|
||||
|
||||
* Install the build dependencies. On Ubuntu use this command:
|
||||
|
||||
### Browser Requirements
|
||||
`sudo aptitude install python-dev bluetooth-dev`
|
||||
|
||||
* HTML5 Canvas: Except for Internet Explorer, most
|
||||
browsers have had Canvas support for quite some time. Internet
|
||||
Explorer 9 will have Canvas support (finally).
|
||||
* Download, build the ssl module and symlink to it:
|
||||
|
||||
* HTML5 WebSockets: For browsers that do not have builtin
|
||||
WebSockets support, the project includes
|
||||
<a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
|
||||
a WebSockets emulator using Adobe Flash.
|
||||
`cd websockify/`
|
||||
|
||||
* Fast Javascript Engine: noVNC avoids using new Javascript
|
||||
functionality so it will run on older browsers, but decode and
|
||||
rendering happen in Javascript, so a slow Javascript engine will
|
||||
mean noVNC is painfully slow.
|
||||
`wget http://pypi.python.org/packages/source/s/ssl/ssl-1.15.tar.gz`
|
||||
|
||||
* I maintain a more detailed list of browser compatibility <a
|
||||
href="http://github.com/kanaka/noVNC/blob/master/docs/browsers.md">here</a>.
|
||||
`tar xvzf ssl-1.15.tar.gz`
|
||||
|
||||
`cd ssl-1.15`
|
||||
|
||||
### Server Requirements
|
||||
`make`
|
||||
|
||||
Unless you are using a VNC server with support for WebSockets
|
||||
connections (only my [fork of libvncserver](http://github.com/kanaka/libvncserver)
|
||||
currently), you need to use a WebSockets to TCP socket proxy. There is
|
||||
a python proxy included ('wsproxy'). One advantage of using the proxy
|
||||
is that it has builtin support for SSL/TLS encryption (i.e. "wss://").
|
||||
`cd ../`
|
||||
|
||||
There a few reasons why a proxy is required:
|
||||
`ln -sf ssl-1.15/build/lib.linux-*/ssl ssl`
|
||||
|
||||
1. WebSockets is not a pure socket protocol. There is an initial HTTP
|
||||
like handshake to allow easy hand-off by web servers and allow
|
||||
some origin policy exchange. Also, each WebSockets frame begins
|
||||
with 0 ('\x00') and ends with 255 ('\xff').
|
||||
|
||||
2. Javascript itself does not have the ability to handle pure byte
|
||||
arrays. The python proxy encodes the data as base64 so that the
|
||||
Javascript client can decode the data as an integer array.
|
||||
|
||||
|
||||
### Quick Start
|
||||
|
||||
* Use the launch script to start a mini-webserver and the WebSockets
|
||||
proxy. The `--vnc` option is used to specify the location of
|
||||
a running VNC server:
|
||||
|
||||
`./utils/launch.sh --vnc localhost:5901`
|
||||
|
||||
* Point your browser to the cut-and-paste URL that is output by the
|
||||
launch script. Enter a password if the VNC server has one
|
||||
configured. Hit the Connect button and enjoy!
|
||||
|
||||
|
||||
### Advanced usage
|
||||
|
||||
* 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/wsproxy.py source_port target_addr:target_port`
|
||||
|
||||
`./utils/wsproxy.py 8787 localhost:5901`
|
||||
|
||||
* To activate the mini-webserver in wsproxy.py use the `--web DIR`
|
||||
option:
|
||||
|
||||
`./utils/wsproxy.py --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 wsproxy to support
|
||||
'wss://' (TLS) then see the
|
||||
[wsproxy README](http://github.com/kanaka/noVNC/blob/master/utils/README.md)
|
||||
for instructions on building the ssl module.
|
||||
|
||||
|
||||
### Integration
|
||||
|
||||
The client is designed to be easily integrated with existing web
|
||||
structure and style.
|
||||
|
||||
At a minimum you must include the `vnc.js` and `ui.js` scripts and
|
||||
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.
|
||||
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
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.

|

* Note 1: Opera interacts poorly with web-socket-js. After two
|
||||
disconnects the browser tab or Flash often hang. Although Javascript
|
||||
is faster than Firefox 3.5, the high variability of web-socket-js
|
||||
performance results in overall performance being lower. Middle mouse
|
||||
clicks and keyboard events need some work to work properly under
|
||||
Opera. Also, Opera does not have support for setting the cursor
|
||||
style url to a data URI scheme, so cursor pseudo-encoding is
|
||||
disabled.
|
||||
|
||||
* Note 2: Firefox 4.0 Beta does not provide a direct way to accept
|
||||
SSL certificates via WebSockets. You can work around this by
|
||||
navigating directly to the WebSockets port using 'https://' and
|
||||
accepting the certificate. Then return to noVNC and connect
|
||||
normally.
|
||||
|
||||
* Note 3: Browsers using WebKit build 66396 through 68867
|
||||
(Chrome/Chromium build 57968 through 61278) have a Canvas rendering
|
||||
bug. The WebKit bug is <a
|
||||
href="https://bugs.webkit.org/show_bug.cgi?id=46319">#46319</a>.
|
||||
The noVNC bug is <a
|
||||

## WebSockets Proxy
|
||||
|
||||
|
||||
### wsproxy
|
||||
|
||||
At the most basic level, wsproxy just translates WebSockets traffic
|
||||
to normal socket traffic. wsproxy accepts the WebSockets handshake,
|
||||
parses it, and then begins forwarding traffic between the client and
|
||||
the target in both directions. WebSockets payload data is UTF-8
|
||||
encoded so in order to transport binary data it must use an encoding
|
||||
that can be encapsulated within UTF-8. wsproxy uses base64 to encode
|
||||
all traffic to and from the client. Also, WebSockets traffic starts
|
||||
with '\0' (0) and ends with '\xff' (255). Some buffering is done in
|
||||
case the data from the client is not a full WebSockets frame (i.e.
|
||||
does not end in 255).
|
||||
|
||||
|
||||
#### Additional wsproxy features
|
||||
|
||||
These are not necessary for the basic operation.
|
||||
|
||||
* Daemonizing: When the `-D` option is specified, wsproxy runs
|
||||
in the background as a daemon process.
|
||||
|
||||
* SSL (the wss:// WebSockets URI): This is detected automatically by
|
||||
wsproxy by sniffing the first byte sent from the client and then
|
||||
wrapping the socket if the data starts with '\x16' or '\x80'
|
||||
(indicating SSL).
|
||||
|
||||
* Flash security policy: wsproxy detects flash security policy
|
||||
requests (again by sniffing the first packet) and answers with an
|
||||
appropriate flash security policy response (and then closes the
|
||||
port). This means no separate flash security policy server is needed
|
||||
for supporting the flash WebSockets fallback emulator.
|
||||
|
||||
* Session recording: This feature that allows recording of the traffic
|
||||
sent and received from the client to a file using the `--record`
|
||||
option.
|
||||
|
||||
* Mini-webserver: wsproxy can detect and respond to normal web
|
||||
requests on the same port as the WebSockets proxy and Flash security
|
||||
policy. This functionality is activate with the `--web DIR` option
|
||||
where DIR is the root of the web directory to serve.
|
||||
|
||||
* Wrap a program: see the "Wrap a Program" section below.
|
||||
|
||||
|
||||
#### Implementations of wsproxy
|
||||
|
||||
There are three implementations of wsproxy: python, C, and Node
|
||||
(node.js). wswrapper is only implemented in C.
|
||||
|
||||
Here is the feature support matrix for the the wsproxy
|
||||
implementations:

||||
* Note 1: to use SSL/wss with python 2.5 or older, see the following
|
||||
section on *Building the Python ssl module*.
|
||||
|
||||
|
||||
### Wrap a Program
|
||||
|
||||
In addition to proxying from a source address to a target address
|
||||
(which may be on a different system), wsproxy has the ability to
|
||||
launch a program on the local system and proxy WebSockets traffic to
|
||||
a normal TCP port owned/bound by the program.
|
||||
|
||||
The is accomplished with a small LD_PRELOAD library (`rebind.so`)
|
||||
which intercepts bind() system calls by the program. The specified
|
||||
port is moved to a new localhost/loopback free high port. wsproxy
|
||||
then proxies WebSockets traffic directed to the original port to the
|
||||
new (moved) port of the program.
|
||||
|
||||
The program wrap mode is invoked by replacing the target with `--`
|
||||
followed by the program command line to wrap.
|
||||
|
||||
`./utils/wsproxy.py 2023 -- PROGRAM ARGS`
|
||||
|
||||
The `--wrap-mode` option can be used to indicate what action to take
|
||||
when the wrapped program exits or daemonizes.
|
||||
|
||||
Here is an example of using wsproxy to wrap the vncserver command
|
||||
(which backgrounds itself):
|
||||
|
||||
`./utils/wsproxy.py 5901 --wrap-mode=ignore -- vncserver -geometry 1024x768 :1`
|
||||
|
||||
Here is an example of wrapping telnetd (from krb5-telnetd).telnetd
|
||||
exits after the connection closes so the wrap mode is set to respawn
|
||||
the command:
|
||||
|
||||
`sudo ./utils/wsproxy.py 2023 --wrap-mode=respawn -- telnetd -debug 2023`
|
||||
|
||||
The `utils/wstelnet.html` page demonstrates a simple WebSockets based
|
||||
telnet client.
|
||||
|
||||
|
||||
### Building the Python ssl module (for python 2.5 and older)
|
||||
|
||||
* Install the build dependencies. On Ubuntu use this command:
|
||||
|
||||
`sudo aptitude install python-dev bluetooth-dev`
|
||||
|
||||
* Download, build the ssl module and symlink to it:
|
||||
|
||||
`cd noVNC/utils`
|
||||
|
||||
`wget http://pypi.python.org/packages/source/s/ssl/ssl-1.15.tar.gz`
|
||||
|
||||
`tar xvzf ssl-1.15.tar.gz`
|
||||
|
||||
`cd ssl-1.15`
|
||||
|
||||
`make`
|
||||
|
||||
`cd ../`
|
||||
|
||||
`ln -sf ssl-1.15/build/lib.linux-*/ssl ssl`
