Guacamole
HTML5 Clientless Remote Desktop
Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.
We call it clientless because no plugins or client software are required.
Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.
you need to edit /opt/Guacamole/user-mapping.xml as prior depending your needs
