I know there is an implementation of VNC using WebSockets (http://novnc.com) but that still requires a server. I am looking to create a simple client-side JavaScript only (no Flash) connection to a port running SSH. I am guessing WebSockets is the only way to go since it does TCP. Any example code? Any other way?

    Sorry, given your constraints (client-side Javascript only), there is no way to connect to a plain old SSH server.

    WebSockets is not plain TCP. It’s a framed protocol with a HTTP-like handshake between the client and server that includes origin policy.

    Flash can make plain TCP connections, but it also has origin policy enforcement. The way it does this is by making a connection to the same server on port 843 and asking for a special XML file that contains the origin policy.
    If you are willing to relax your constraints slightly such that you are willing to run a generic WebSockets to TCP proxy either on a server (any server) or on the client then you can do what you are wanting to do. noVNC includes a C and python WebSockets to TCP proxy: http://github.com/kanaka/noVNC/tree/master/utils/.
