## custom fork of noVNC: HTML VNC Client Library and Application
|
|
|
|
# code from novnc arch package may not work as from main repo
|
|
|
|
### Description
|
|
|
|
noVNC is both a HTML VNC client JavaScript library and an application built on
|
|
top of that library. noVNC runs well in any modern browser including mobile
|
|
browsers (iOS and Android).
|
|
|
|
Many companies, projects and products have integrated noVNC including
|
|
[OpenStack](http://www.openstack.org),
|
|
[OpenNebula](http://opennebula.org/),
|
|
[LibVNCServer](http://libvncserver.sourceforge.net), and
|
|
[ThinLinc](https://cendio.com/thinlinc). See
|
|
[the Projects and Companies wiki page](https://github.com/novnc/noVNC/wiki/Projects-and-companies-using-noVNC)
|
|
for a more complete list with additional info and links.

### Browser Requirements
|
|
|
|
noVNC uses many modern web technologies so a formal requirement list is
|
|
not available. However these are the minimum versions we are currently
|
|
aware of:
|
|
|
|
* Chrome 64, Firefox 79, Safari 13.4, Opera 51, Edge 79
|
|
|
|
|
|
### Server Requirements
|
|
|
|
noVNC follows the standard VNC protocol, but unlike other VNC clients it does
|
|
require WebSockets support. Many servers include support (e.g.
|
|
[x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
|
|
[QEMU](http://www.qemu.org/), and
|
|
[MobileVNC](http://www.smartlab.at/mobilevnc/)), but for the others you need to
|
|
use a WebSockets to TCP socket proxy. noVNC has a sister project
|
|
[websockify](https://github.com/novnc/websockify) that provides a simple such
|
|
proxy.
|
|
|
|
|
|
### Quick Start
|
|
|
|
* Use the `novnc_proxy` script to automatically download and start websockify, which
|
|
includes a mini-webserver and the WebSockets proxy. The `--vnc` option is
|
|
used to specify the location of a running VNC server:
|
|
|
|
`./utils/novnc_proxy --vnc localhost:5901`
|
|
|
|
* If you don't need to expose the web server to public internet, you can
|
|
bind to localhost:
|
|
|
|
`./utils/novnc_proxy --vnc localhost:5901 --listen localhost:6081`
|
|
|
|
* Point your browser to the cut-and-paste URL that is output by the `novnc_proxy`
|
|
script. Hit the Connect button, enter a password if the VNC server has one
|
|
configured, and enjoy!
|
|
|
|
### Installation from Snap Package
|
|
Running the command below will install the latest release of noVNC from Snap:
|
|
|
|
`sudo snap install novnc`
|
|
|
|
#### Running noVNC from Snap Directly
|
|
|
|
You can run the Snap-package installed novnc directly with, for example:
|
|
|
|
`novnc --listen 6081 --vnc localhost:5901 # /snap/bin/novnc if /snap/bin is not in your PATH`
|
|
|
|
If you want to use certificate files, due to standard Snap confinement restrictions you need to have them in the /home/\<user\>/snap/novnc/current/ directory. If your username is jsmith an example command would be:
|
|
|
|
`novnc --listen 8443 --cert ~jsmith/snap/novnc/current/self.crt --key ~jsmith/snap/novnc/current/self.key --vnc ubuntu.example.com:5901`
|
|
|
|
#### Running noVNC from Snap as a Service (Daemon)
|
|
The Snap package also has the capability to run a 'novnc' service which can be
|
|
configured to listen on multiple ports connecting to multiple VNC servers
|
|
(effectively a service runing multiple instances of novnc).
|
|
Instructions (with example values):
|
|
|
|
List current services (out-of-box this will be blank):
|
|
|
|
```
|
|
sudo snap get novnc services
|
|
Key Value
|
|
services.n6080 {...}
|
|
services.n6081 {...}
|
|
```
|
|
|
|
Create a new service that listens on port 6082 and connects to the VNC server
|
|
running on port 5902 on localhost:
|
|
|
|
`sudo snap set novnc services.n6082.listen=6082 services.n6082.vnc=localhost:5902`
|
|
|
|
(Any services you define with 'snap set' will be automatically started)
|
|
Note that the name of the service, 'n6082' in this example, can be anything
|
|
as long as it doesn't start with a number or contain spaces/special characters.
|
|
|
|
View the configuration of the service just created:
|
|
|
|
```
|
|
sudo snap get novnc services.n6082
|
|
Key Value
|
|
services.n6082.listen 6082
|
|
services.n6082.vnc localhost:5902
|
|
```
|
|
|
|
Disable a service (note that because of a limitation in Snap it's currently not
|
|
possible to unset config variables, setting them to blank values is the way
|
|
to disable a service):
|
|
|
|
`sudo snap set novnc services.n6082.listen='' services.n6082.vnc=''`
|
|
|
|
(Any services you set to blank with 'snap set' like this will be automatically stopped)
|
|
|
|
Verify that the service is disabled (blank values):
|
|
|
|
```
|
|
sudo snap get novnc services.n6082
|
|
Key Value
|
|
services.n6082.listen
|
|
services.n6082.vnc
|
|
```
|
|
|
|
