Question
Which tool captures full data packets with a command-line interface only?
- NBAR2
- nfdump
- tcpdump
- Wireshark
Solution
The tool that captures full data packets with a command-line interface only is tcpdump.
Here's a step-by-step explanation:
-
NBAR2: This is a Cisco technology used for identifying and classifying network traffic. It does not capture full data packets and it does not have a command-line interface only.
-
nfdump: This is a set of tools to collect and process netflow data. It's not specifically designed to capture full data packets.
-
tcpdump: This is a data-network packet analyzer computer program that runs under a command-line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network. This is the correct answer.
-
Wireshark: This is a popular network protocol analyzer. It has a graphical user interface, not a command-line interface only. It's used for network troubleshooting, analysis, software and communications protocol development, and education.
