Ss

The ss command (short for socket statistics) is a fast, feature-rich replacement for the older netstat utility. It allows administrators to inspect and manage network sockets on a system — whether they’re TCP, UDP, RAW, or UNIX domain sockets. Compared to netstat, ss runs faster and provides more filtering options, making it invaluable for network diagnostics and system monitoring.

ss -a -t -u -w -x

Motivation: Network administrators often need a complete snapshot of all active sockets — to check which services are listening, what connections are established, or to detect unusual activity.
