Relay for bidirectional data transfer
Socat is a relay for bidirectional data transfer between two independent data channels. Data channels may be files, pipes, devices (terminal or modem, etc.), or sockets (Unix, IP4, IP6 - raw, UDP, TCP), etc. It provides forking, logging, and tracing, different modes for interprocess communication, and many more options. It can be used, for example, as a TCP relay (one-shot or daemon), as an external socksifier, as a shell interface to Unix sockets, as an IP6 relay, as a netcat and rinetd replacement, for redirecting TCP-oriented programs like brutus to a serial line, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.
