Operating System Commands

Another recommendation is to use operating system commands (for example, Netstat and Traceroute), which are also effective for troubleshooting and debugging purposes.

Netstat is a command-line tool that displays network connections (incoming and outgoing), routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics. For more information, see:

Traceroute is a network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. For more information, see:
