flashproxy-client(1) The flash proxy client transport plugin


flashproxy-client --register [OPTIONS] [LOCAL][:PORT] [REMOTE][:PORT]


Wait for connections on a local and a remote port. When any pair of connections exists, data is ferried between them until one side is closed. By default LOCAL is localhost addresses on port 9001 and REMOTE is all addresses on port 9000.

The local connection acts as a SOCKS4a proxy, but the host and port in the SOCKS request are ignored and the local connection is always linked to a remote connection.

By default, runs as a managed proxy: informs a parent Tor process of support for the "flashproxy" or "websocket" pluggable transport. In managed mode, the LOCAL port is chosen arbitrarily instead of defaulting to 9001; however this can be overridden by including a LOCAL port in the command. This is the way the program should be invoked in a torrc ClientTransportPlugin "exec" line. Use the --external option to run as an external proxy that does not interact with Tor.

If any of the --register, --register-addr, or --register-methods options are used, then your IP address will be sent to the facilitator so that proxies can connect to you. You need to register in some way in order to get any service. The --facilitator option allows controlling which facilitator is used; if omitted, it uses a public default.



Registration helpers use IPv4.


Registration helpers use IPv6.


Daemonize (Unix only).


Be an external proxy (don't interact with Tor using environment variables and stdout).

-f, --facilitator=URL

Advertise willingness to receive connections to URL.


Encrypt registrations to the given PEM-formatted public key (default built-in).

-h, --help

Display a help message and exit.

-l, --log=FILENAME

Write log to FILENAME (default is stdout).


Write PID to FILENAME after daemonizing.


Attempt to forward REMOTE port.


Use the given PROGRAM to forward ports (default "tor-fw-helper"). Implies --port-forwarding.


Forward the external PORT to REMOTE on the local host (default same as REMOTE). Implies --port-forwarding.

-r, --register

Register with the facilitator.


Register the given address (in case it differs from REMOTE). Implies --register.


Register using the given comma-separated list of methods. Implies --register. Possible methods are: appspot, email, http. Default is "appspot,email,http".


Registrations include the fact that you intend to use the given TRANSPORT (default "websocket").
