You can't listen() for connections on a connectionless
protocol. The listen() operation is only valid for
connection-oriented protocols, and not for datagram protocols.
To accept connections, a socket is first created with
socket(2), a willingness to accept incoming connections
and a queue limit for incoming connections are specified
with listen, and then the connections are accepted with
accept(2). The listen call applies only to sockets of
type SOCK_STREAM or SOCK_SEQPACKET.

Skip the listen() call and just call recv().
