This tool listens for several clients connections. It can show received data to screen (--showscreen), and echo it back to client (--echoback). Parameter --src-port defines the local port number to listen on. Optional parameter --src-ip defines the local IP address to use. Optional parameter --iptype defines which kind of IP address to use when --src-ip is unset (accepted values: ip4 and ip6). Optional parameter --ip4opts permits to add IP4 options encoded as mixed. Optional parameter --ip6exts permits to add IP6 options encoded as mixed (first byte is the next header number). Optional parameters --device and --src-eth are not yet implemented.
