Netstat - Native to Linux / Windows

 NETSTAT

Netstat is a tool built into both Linux and Windows, but the syntax is different between the two operating systems.

Several ways this local command line tool can be utilized:

• See what ports (services) are in a listening state, both TCP and UDP ports.
• See what files are being accessed and which computers are involved.
• See if any systems are connected before rebooting a server.
• See what process established the connection (such as Zoom, Firefox, Chrome, Edge, etc.)
• Display ethernet statistics
• Display the owning process ID
• Display the routing table
