Explanation

ss is the modern replacement for netstat for displaying socket statistics. The flags -pint show: -p (process using the socket), -i (internal TCP information), -n (numeric addresses, no DNS resolution), -t (TCP sockets). This provides a comprehensive view of listening and established connections with associated processes. tcpdump -nL captures live traffic, not a static port list. netstat -pn works but ss is preferred on modern systems. lsof -lt lists open files by type but is less targeted for network port reporting.
