ss - Display sockets statistics

Edit online

Use the ss command to analyze the sockets that run on a Linux system.

The ss command replaces netstat, which is deprecated. The options for ss are similar to the netstat options.

Issue ss -r for a table of statistics with resolved addresses. For more information, see the man page.

Example

To start ss -r, issue: 
[root@system]# ss -r
