smc-sock is a simple command line tool for testing SMC connections. It opens an AF_SMC socket and runs either as server or as a client. As client, it connects to a server, sends a text message over the SMC connection, reads the reply from the server, and terminates. As server, it waits for a client connection, reads the message from the client and returns it to the client.

You can run smc-sock with the following command line arguments:

 -a address listen on (server) or connect to (client) address (default "127.0.0.1:50000") -c run as client -s run as server -t text transfer text (default "Hello, world!")
