ssnetstat

ssnetstat is a command-line utility that provides network statistics. It is a modern replacement for the older netstat command and offers a more efficient and feature-rich way to examine network connections, routing tables, interface statistics, and more. The primary advantage of ssnetstat lies in its speed and its ability to display a larger volume of information than netstat.

The utility works by directly querying kernel network data structures. This allows it to gather information rapidly without the need for parsing less efficient sources. ssnetstat can display TCP, UDP, and Unix domain sockets. It can show established connections, listening sockets, and sockets in various states of transition.

Common uses for ssnetstat include identifying which processes are listening on which ports, troubleshooting network connectivity issues, and monitoring network traffic. Users can filter the output based on various criteria such as protocol, port number, and connection state. For instance, one might use ssnetstat to quickly see all active TCP connections or to find out which application is using a specific port. The command's syntax is generally more concise than netstat, making it a preferred tool for many system administrators and network engineers.
