noVNC uses WebSockets to connect to the server.
However, noVNC is still limited by the fact that Javascript cannot make plain TCP connections.

The closest thing is the incomplete WebSockets standard, but even that is a framed protocol that has a HTTP-like handshake to initiate it.Įven though Adobe Flash programs can make plain TCP connections, they still require that the server you are connecting to answer with a policy file either on port 843 or the port you are connecting to ( ).Īs has been noted, Guacamole requires a Java proxy to communicate between their HTML5 based interface and the VNC server.Īnother option is noVNC ( github) which has a full VNC client implementation in Javascript/HTML5 (unlike Guacamole where the VNC protocol is in the proxy). The biggest issue is that web browsers cannot make plain TCP connections. no Flash, Java or ActiveX) to connect directly to a 100% plain VNC server. There are various solutions, but none of them will allow a 100% plain web app (i.e. With the necessary dependencies in place, building Guacamole only takes a few minutes. You just need to be sure you have the necessary tools installed ahead of time.
Don't be discouraged: building the components of Guacamole from source is not as difficult as it sounds, and the build process is automated. Guacamole-client is available in binary form, but guacamole-server must be built from source. Guacamole is separated into two pieces: guacamole-server, which provides the guacd proxy and related libraries, and guacamole-client, which provides the client to be served by your servlet container, usually Tomcat. However, this should be trivial, even if you don't already have a Java server up and running (Tomcat is pretty simple, and Guacamole's instructions are straightforward): On the downside, it requires a Java server to proxy through. Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

We call it clientless because no plugins or client software are required. It supports standard protocols like VNC and RDP. Guacamole is a clientless remote desktop gateway.
