To do that, you should retrieve the tcp or udp header from the ip packet, read the port from it, then try to execute netstat
command using Runtime
class,
parse the result, you will find the pid
of the process in the last column of the result, you will also find the port
, netstat will list the running process, their state and the ports their are listening on.
capturing network packet and group them according to their process (program) name
