@unixrab Here are some additional ss command examples that are not already listed in the article:

  1. Show all TCP sockets in the SYN-RECV state:
ss -tan state syn-recv

This command will display all TCP sockets that are in the SYN-RECV state. This state is typically associated with incoming connections that are in the process of being established.

  1. Display detailed information about a specific port:
ss -tln sport = :80

This command will show detailed information about the TCP sockets that are listening on port 80. You can replace :80 with the specific port you want to investigate.

  1. List all TCP sockets using a specific address family (IPv4 or IPv6):
ss -t4

This command will list all TCP sockets using both IPv4 and IPv6 address families. You can use -t4 for IPv4 only or -t6 for IPv6 only.

  1. Display all listening and non-listening UDP sockets:
ss -u -a

This command will show both listening and non-listening UDP sockets on the system. It provides a comprehensive view of UDP sockets.
