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().
