 # KasmVNC - Linux Web Remote Desktop

 <a href="https://kasmweb.com"><img src="https://kasm-static-content.s3.amazonaws.com/logo_kasm.png" width="300"><a/>
-  
-[Kasm Technologies](https://www.kasmweb.com) developed Kasm Workspaces, the Containerized Streaming Platform. Kasm has open-sourced the Workspace docker images, which include containerized [full desktops and apps](https://github.com/kasmtech/workspaces-images) and [base images](https://github.com/kasmtech/workspaces-core-images) intended for developers to create custimized streaming containers. These containers can be used standalone or within the [Kasm Workspaces Platform](https://www.kasmweb.com) which provides a full Enterprise feature set. KasmVNC is used as the streaming tech for our container images, however, you can use KasmVNC for individual servers. While the term VNC is in the name, KasmVNC is not intended to remain compliant with the RFB spec and has different goals than other VNC projects:

-  - Web-based - KasmVNC is designed to provide a web accessible remote desktop. It comes with a web server and websocket server built in. There is no need to install other components. Simply run and navigate to your desktop's URL on the port you specify. While you can still tun on the legacy VNC port, it is disabled by default.
-  - Security - The RFB specification (VNC) limits the password field to 8 characters, so while the client may take a longer password, only the first 8 characters are sent. KasmVNC defaults to HTTPS with HTTP Basic Auth and disables the legacy VNC authentication method which is not sufficiently secure for internet accessible systems.
-  - Simplicity - KasmVNC aims at being simple to deploy and configure.
+KasmVNC provides remote web-based access to a Desktop or application. While VNC is in the name, KasmVNC differs from other VNC variants such as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB specification which defines VNC, in order to support modern technologies and increase security. KasmVNC is accessed by users from any modern browser and does not support legacy VNC viewer applications. KasmVNC uses a modern YAML based configuration at the server and user level, allowing for ease of management.

+
+## Documentation
+
+**Do not use the README from the master branch**, unless you are compiling KasmVNC yourself from the tip of master. Use the documentation for your specific release.
+
+  - [KasmVNC 1.0.0 Documentation](https://www.kasmweb.com/kasmvnc/docs/1.0.0/index.html)
+
+  For beta releases prior to version 1.0.0, use the README in this github project on the tagged commit for that release.
+
+## Installation
+
+**You must disconnect and reconnect to the server after installation, for the group membership to apply.**
+
+### Debian/Ubuntu/Kali
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+sudo apt-get install ./kasmvncserver_*.deb
+
+# Add your user to the ssl-cert group
+sudo adduser $USER ssl-cert
+```
+
+### Oracle 8
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+# Ensure KasmVNC dependencies are available
+sudo dnf config-manager --set-enabled ol8_codeready_builder
+sudo dnf install oracle-epel-release-el8
+
+sudo dnf localinstall ./kasmvncserver_*.rpm
+
+# Add your user to the kasmvnc-cert group
+sudo usermod -a -G kasmvnc-cert $USER
+```
+
+### CentOS 7
+
+```sh
+# Please choose the package for your distro here (under Assets):
+# https://github.com/kasmtech/KasmVNC/releases
+wget <package_url>
+
+# Ensure KasmVNC dependencies are available
+sudo yum install epel-release
+
+sudo yum install ./kasmvncserver_*.rpm
+
+# Add your user to the kasmvnc-cert group
+sudo usermod -a -G kasmvnc-cert $USER
+```
+
+## Getting Started
+
+The following examples provide basic usage of KasmVNC with the tools provided. For full documentation on all the utilities and the runtime environment, see our [KasmVNC Documentation](https://www.kasmweb.com/kasmvnc/docs/latest/index.html)
+
+```sh
+# Start a session and be guided to setup a user and select a default desktop environment
+vncserver
+
+# Start a session with the mate desktop environment
+vncserver -select-de mate
+
+# Add a new user with read/write permissions
+vncpasswd -u my_username -w -r
+
+# Tail the logs
+tail -f ~/.vnc/*.log
+
+# Get a list of current sessions with display IDs
+vncserver -list
+
+# Kill the VNC session with display ID :2
+vncserver -kill :2
+```
+
+## Configuration
+
+KasmVNC is configured via YAML based configurations. The server level configuration is at `/etc/kasmvnc/kasmvnc.yaml`. Edits to this file apply to all users. Individual users can override server global configurations by specifying them in their configuration file at `~/.vnc/kasmvnc.yaml`.
+
+The following configuration shows all default settings. Many of the encoding settings can be overridden by the client, unless the `runtime_configuration.allow_client_to_override_kasm_server_settings` setting is set tot false. By default the client is allowed to modify encoding settings.
+
+For a full description of each setting see the [configuration reference](https://www.kasmweb.com/kasmvnc/docs/latest/configuration.html).

-Since this is a fast evolving project, the documents on the tip of master are chaning rapidly and will not match releases. Be sure to use the README and other documentation from the release branch that matches the version of KasmVNC you are using. Do not use the README from the master branch, unless you are compiling KasmVNC yourself from the tip of master. All releases starting at 0.9.3 have a branch named in the format 'release/0.9.3', for example. 

 # New Features!

-### Installation
-
-#### Debian-based
-
-```sh
-# Please choose the package for your distro here (under Assets):
-# https://github.com/kasmtech/KasmVNC/releases
-wget <package_url>
-
-sudo apt-get install ./kasmvncserver_*.deb
-
-# We provide an example script to run KasmVNC at #
-# /usr/share/doc/kasmvncserver/examples/kasmvncserver-easy-start. It runs a VNC
-# server on display :10 and on interface 0.0.0.0. If you're happy with those
-# defaults you can just use it as is:
-sudo ln -s /usr/share/doc/kasmvncserver/examples/kasmvncserver-easy-start /usr/bin/
-
-# Add your user to the ssl-cert group
-sudo addgroup $USER ssl-cert
-# You will need to re-connect in order to pick up the group change
-
-# Create a KasmVNC user able to use keyboard and mouse:
-vncpasswd -u $USER -w
-
-# Create ~/.vnc directory and corresponding files.
-kasmvncserver-easy-start -d && kasmvncserver-easy-start -kill
-
-# Modify vncstartup to launch your environment of choice, in this example LXDE
-# This may be optional depending on your system configuration
-echo '/usr/bin/lxsession -s LXDE &' >> ~/.vnc/xstartup
-
-# Start KasmVNC with debug logging:
-kasmvncserver-easy-start -d
-
-# Tail the logs
-tail -f ~/.vnc/`hostname`:10.log
-```
-
-Now navigate to your system at https://[ip-address]:8443/
-
-To stop a running KasmVNC:
-
-```sh
-kasmvncserver-easy-start -kill
-```
-
-The options for vncserver:
-
-| Argument | Description |
-| -------- | ----------- |
-| depth | Color depth, for jpeg/webp should be 24bit |
-| geometry | Screensize, this will automatically be adjusted when the client connects. |
-| websocketPort | The port to use for the web socket. Use a high port to avoid having to run as root. |
-| cert | SSL cert to use for HTTPS |
-| sslOnly | Disable HTTP |
-| interface | Which interface to bind the web server to. |
-
-### Development
-Would you like to contribute to KasmVNC? Please reachout to us at info@kasmweb.com. We have investigated or are working on the following, if you have experience in these fields and would like to help please let us know.
-
-Real-time H264 encoding using NVIDIA and Intel encoding technology.
-
-Windows version of KasmVNC. We have been able to get it to compile for Windows and increased the performance, but still not releasable. Experienced Windows developers with a background in cross compiling would help.
-  
-ARM version of KasmVNC, we have had requests for this and at one point we did have an ARM build of KasmVNC but it takes dev cycles to mainain and bring it back to life.
-
 ### Compiling From Source
 See the [builder/README.md](https://github.com/kasmtech/KasmVNC/blob/master/builder/README.md). We containerize our build systems to ensure highly repeatable builds.

+Same for configuration files.

+Python specs can be run with `ty` alias inside devenv.
+
+### Debug output
+To see `vncserver` output, run `ty -d`. Anything you print inside `vncserver`
+with `say` should be visible that way.
+
+### Finding which spec produces a warning
+By default, each passing test is represented as a dot. `-v` flag causes tests to
+emit test descriptions alongside the program's output. Run `ty -v`.

 # ARM

 KasmVNC is supported on ARM, however, the build process needs to be broken into two parts with one occuring on a x64 system and the other on an ARM system. All our testing and official builds are done on AWS Graviton instances.
