Inspecting Network Connections and Sockets
Use modern Linux tools to list open ports, active connections, and the processes behind them so you can understand what your machine is talking to.
Why Inspect Connections?
Knowing which ports are open and which connections are live is key to debugging services, catching unexpected traffic, and confirming an app listens where you expect.
Meet ss
The modern tool for socket inspection is ss (socket statistics). It replaces older netstat and runs far faster on busy systems.
