ss

The command line tool "ss" stands for "socket statistics" and is used in Linux systems to display detailed information about network sockets, interfaces, and network connections. It is considered a replacement for the old "netstat" command.

1. The "ss" command is used primarily for debugging and monitoring network activity on a Linux system.
2. It provides information on socket states, such as established, listening, or closed.
3. It can display information about both IPv4 and IPv6 connections.
4. The output of the "ss" command can be filtered using several options, allowing users to focus on specific network connections or socket states.
5. It shows details like the address and port number for each connection, the amount of data transferred, and the process ID associated with each socket.
6. The "ss" command provides a reliable way to gather information about network connections, making it useful for troubleshooting network-related issues.
7. It is often used in combination with other command line tools, such as "grep" or "awk", to perform more advanced network analysis or filtering tasks.
