I have something running at port 9090 on my local machine.

It's probably something I set up long ago and forgot about... how can I find out what it is?

I am using Windows 8.

This question came from our site for system and network administrators.

    It's netstat -b, but this question is off topic because it does not appear to relate to professional systems administration. – Ryan Ries Feb 6 '14 at 22:30

    Maybe I should have put it on SuperUser? Thanks for the hint though. – BanksySan Feb 6 '14 at 22:35

Run netstat -a -o | find "9090" and have a look at the far right column. That's the Process ID (PID) of the owning process. Match it up with running processes in Task Manager.

  • If I try this I do get a process id on the fa right column but no process exists in the task manager with exactly that ID. the ID for me is 15936 but in the process manager the PID's go ....,15792, 15904, 16080,... if I arrange them in ascending order....How to fix this please? I then tried tasklist /fi "pid eq 15936" and got INFO: No tasks are running which match the specified criteria – user32882 Sep 21 '17 at 9:11

Did you ever install Zeus admin server or Zyxel VoIP or CiscoSecure on that machine? Other possibilities include a Trojan such as Aphex's Remote Packet Sniffer or the IANA WebSM designation.

Take a look here or search the web for port 9090 or any other for that matter.

You can always do a basic intrusion testing using the GRC ShieldsUp! service.
