netstatsupports a set of options to display active or passive sockets. The options –t, –u, –w, and –x show active TCP, UDP, RAW, or Unix socket connections. If you provide the –a flag in addition, sockets that are waiting for a connection (i.e., listening) are displayed as ...
How to Check Which Linux Ports Are in Use? Three tools to help you check ports in use on a Linux system are: netstat: This tool shows your server’s network status. ss: You can view socket statistics with the ss tool. For example, ss allows you to monitor TCP, UDP, and UNIX sock...
