Node.js + Socket.io + Bash. A collaborative terminal for your browser - updated for socket.io 0.7
Raw
server.js
//
// This server will start a bash shell and expose it
// over socket.io to a browser. See ./term.html for the
// client side.
//
// You should probably:
//
// npm install socket.io
// curl -O https://github.com/LearnBoost/Socket.IO/raw/master/socket.io.min.js
//
// To get socket.io in the node_modules directory and
// the socket.io.min.js file needed for the client.
//
// To start the server:
//
// node server.js
//
// And then load up your term!
//
// open http://`hostname`:8080/term.html
//
// You can even share the url with a friend on your
// local network. Be sure they're a friend though :-)

Hi, (sorry for my poor English)
I'm tying to use your example, starting Server.js is good, but when i trying to connect term.html in a browser, this error appeared :

/var/www/socket/server.js:52
path.exists(filename, function(exists) {
^
