lsof will show a socket open as a file descriptor - and open file - which it truly is.
If you know the port number you have the process pid that has the port open.
Read the looong man page for the options you want. You need the pid of the process holding a socket for the port
Use fuser/lsof/proc to find the files the process pid has open
