What command is used to replace the deprecated netstat command for network status?

The command used to replace the deprecated netstat command for network status is the 'ss' command. 'ss' stands for socket statistics and is a modern utility that provides detailed information about network connections, including both TCP and UDP sockets. It is designed to be faster and more efficient than netstat, particularly when handling a large number of connections, making it a preferred tool for network diagnostics and monitoring.

The 'ss' command is part of the iproute2 package, which has largely replaced the net-tools package that included netstat. Users can obtain similar information to what netstat provided but with a more extensive range of features and options.

For example, 'ss -tuln' can provide a list of listening TCP and UDP sockets, along with the corresponding process IDs, making it especially useful for system administrators looking to manage or troubleshoot network activities efficiently.

In contrast, the other choices are either outdated or serve different functions. 'ifconfig' is used for configuring network interfaces and has largely been replaced by 'ip' commands, while 'ip a' is primarily for displaying IP addresses and does not provide the same level of detail about sockets and connections as 'ss' does. The command 'netstat -a' would still invoke netstat
