Ben would like to identify all of the active network connections and services listening for connections on a Linux system that he is analyzing. What command-line utility can he use to meet this need?

A. tcpdump
B. pstools
C. netcat
D. netstat

Correct Answer: D.

The netstat command lists all of the active network connections on a system as well as the status of ports that are listening for requests. The tcpdump command captures network traffic and would see active network connections but does not identify ports that are listening without an active connection. The pstools comand is used to find infomration about processes running on a system but does not provide network port or version information. The netcat command is used to send information via a network pipe.

    I have Darrel Gibson’s book and I wanted to know if I should study it cover to cover or do you have another way that would be more useful? My test is in December.
