Can you name the main network commands used in Linux for diagnostics and network configuration?

Main network commands in Linux for diagnostics and network configuration:

• ifconfig — view and configure network interfaces (deprecated, replaced by ip).
• ip — modern command for managing network interfaces, routes, addresses.
• ping — check the availability of a remote host over the network.
• traceroute — determine the route to a remote node.
• netstat — display network connections, routing tables, statistics.
• ss — modern alternative to netstat for viewing sockets.
• dig and nslookup — DNS queries for diagnostics.
• route — view and modify the routing table.
• ethtool — view and configure network interface parameters.
• tcpdump — capture and analyze network traffic.

Example of using ip to view interfaces:

ip addr show

To check host availability:

ping 8.8.8.8
