Type in "sudo netstat -antlp|grep 6703" to see if it returns anything - it should in your case. The rightmost column in the result is the PID of the running process using the port. The you can type in "sudo ps -ef|grep <pid>" to see what the exact process is. Make sure you prefix the commands with "sudo" so that you can search among all processes running on the machine.
