Exam XK0-005 topic 1 question 167 discussion

A. ss -plnt The ss command (Socket Stat) is a modern replacement for netstat, providing more detailed information about network connections and sockets. The options used here: -p: Shows the PROCESS using the socket. -l: Lists only LISTENING sockets. -n: Shows NUMERICAL addresses instead of resolving hostnames. -t: Filters for TCP sockets. This command specifically shows processes that are listening on network ports, making it the most suitable choice for the task.

The command that would provide information about processes listening on network ports in a Linux server is: A. ss -plnt This command will list all listening TCP ports along with the process information. So, option A is the correct choice.

I use: nmap localhost

A. ss -plnt Explanation: The ss command in Linux is used to display detailed socket information, such as which processes are listening on which ports, among other things. The -p option displays the process ID and process name that are using the socket. The -l option displays only listening sockets. The -n option displays the port numbers in numerical form, and the -t option displays only TCP sockets. C. netstat -pn - This command displays information about network connections, routing tables, and a variety of network statistics. The -p option shows the process ID and process name associated with each socket, but it may not work on all systems, and netstat itself has largely been deprecated in favor of newer utilities like ss.
