On a Linux system, if a program claims that a port is in use (say I want to install a web server on port 80, but the web server claims port 80 is already in use, and a ps auwx doesn't show/claim a web server is running), is there a program that can tell me what application is using the port? Yes, nmap will show ports, but the apps it shows are part of its own built-in database or /etc/services, so the app report isn't accurate. netstat -a will show apps and their PIDs, then later what ports are open, but no direct port <-> app mapping. Maybe there is a compilation of ssh server designed to listen on port 65530, and the daemon name is something I wouldn't expect, or it is invoked by some other application. What tool can I use for real-time port <-> app mapping? Thanks.
