See the "Wrap a Program" section below for an example of using Websock and websockify as a browser telnet client (wstelnet.html). The Websock API is documented on the websock.js API wiki page: Several rQ* methods are available to read binary data off of the receive queue.

Websock has built-in receive queue buffering the message event does not contain actual data but is simply a notification that there is new data available. This is accomplished by base64 encoding the data stream between Websock and websockify. The websock.js (see ) Javascript library library provides a Websock object that is similar to the standard WebSocket object but Websock enables communication with raw TCP sockets (i.e. Openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem When asked for the common name, use the hostname of the server where the proxy will be running: You can generate a self-signed certificate using openssl. By default websockify loads a certificate file name self.pem but the -cert=CERT option can override the file name. To encrypt the traffic using the WebSocket ' wss://' URI scheme you need to generate a certificate for websockify to load. This does not affect the data between websockify and the server.Įncrypted WebSocket connections ( wss://) Websockify uses base64 to encode all traffic to and from the client. In order to transport binary data over UTF-8 an encoding must used to encapsulate the data within UTF-8. The older Hixie versions of the protocol only support UTF-8 text payloads. Websockify supports all versions of the WebSockets protocol (Hixie and HyBI). Websockify was formerly named wsproxy and was part of the noVNC project. Websockify accepts the WebSockets handshake, parses it, and then begins forwarding traffic between the client and the target in both directions. wrap-mode=MODE action to take when the wrapped program exits orĭaemonizes: exit (default), ignore, respawnĪt the most basic level, websockify just translates WebSockets traffic to normal TCP socket traffic. ssl-only disallow non-encrypted connections key=KEY SSL key file (if separate from cert) timeout=TIMEOUT after TIMEOUT seconds exit when not connected run-once handle a single WebSocket connection and exit D, -daemon become a daemon (background process) v, -verbose verbose messages and per frame traffic h, -help show this help message and exit Websockify source_port - WRAP_COMMAND_LINE Websockify source_port target_addr:target_port Websockify - WebSockets to TCP socket bridge
