I have installed the InsigheManager tool in the Compaw G2 Server. During the installation, It asked me to close port 2301, I went around to stop most of serveice in the service console and checked port by netstat, finally the port 2301 disappeared. Installation completed, but it takes time.

So, Is there any tool that can find what service/application is running the port number in order to ease the job ?

Please advise.

this lists all of the assigned port numbers.

you can also check your /etc/services file to see if the port is listed in there.
