This is a websocket server written in bash that uses netcat and openssl. I made it because I wanted to write something in bash and I needed a way to send something like a push notification to a browser. That said, this server not recieve messages, only sends them.
It works fine with chromium.
##Included files
index.html- this is a sample web page that sets up a websocket connection and does stuff when it recieves a message.pipe_to_websocket.sh- this is the server that accepts a named pipe as its single argument. When a client connects to it, it does the websocket handshake then sends whatever data comes through the named pipe to the client.run- the script that runs the server. It sets up a named pipe and forwards any input from stdin to it.
##TODO
- Clean up the bash (it has some korn shell syntax in there)
- Maybe include functionality to receive messages?
##Credits
I found a lot of the code online and managed to hack it together so that it works for me. Here are the sites I used:
- ssklogs - the websocket handshake code
- suxue's server - websocket frame encoding
