This is a free reimplementation of the ngrok v2 protocol. The information has been obtained by reverse-engineering the official client.

usage: ngrok.py [--auth-token <auth_token>] <protocol> <port> [addr]

<protocol> can be one of `https`, `http`, `tls`, `tcp`.
<port> is the target port on your machine.
<addr> (optional) is the reserved remote address, if any.

ngrok.connect(auth_token="") -> ngrok.Ngrok

Creates a new connection to ngrok. auth_token is an optional authentication token.

Ngrok.bind_http(self, addr=None, proto="https") -> str

Requests a tunnel, according to the protocol in proto (may be one of https, http, tls). addr, if supplied, must be a reserved hostname for the current user.

Ngrok.bind_tcp(self, addr=None)

Requests a TCP tunnel. addr, is supplied, must be a (host, port) tuple corresponding to a reserved TCP port for the current user.

Returns a (host, port) pair for the TCP port that has been bound to.

Ngrok.accept(self)

Waits for an incoming connection.

Returns a tuple (sock, (host, port)), where sock is a subclass of io.RawIOBase (NOT socket.socket), and (host, port) corresponds to the client's TCP port.
