Listening Ports And Services

| | No TrackBacks
At times it's necessary to learn what ports the current system is listening on and what service uses a given port.

The simplest approach is to open a command-line box and type
netstat -anb

It will collect and print all the information about applications listening to ports, this kind of report is sufficient in majority of cases.

If you need more details, perhaps the Port Reporter tool, available from Microsoft site, is what you need. The utility can provide the following information:

  • The ports that are used
  • The processes that use the port
  • Whether a process is a service
  • The modules that a process loaded
  • The user accounts that run a process
