Is it possible to analyze ICMP packets with tcpdump?

Show Suggested Answer Hide Answer
Suggested Answer: A

Yes, it is possible to analyze ICMP packets with tcpdump. While tcpdump is often associated with capturing TCP packets, it is not limited to them and can capture and analyze any protocol that traverses the network, including ICMP, which operates at Layer 3 (Network Layer) of the OSI model. ICMP packets do not use ports, but tcpdump can filter and display these packets based on other criteria such as type and code fields.

I think option C makes sense, tcpdump may not be able to analyze ICMP packets

Haha, this is a classic networking exam question. I bet the answer is C - tcpdump is for layer 4, ICMP is layer 3, so it's not a match!

User 2: Haha, that's correct! Tcpdump can analyze ICMP packets as well.

C) No, tcpdump works from layer 4. ICMP is located in the network layer (layer 3), therefore is not applicable to this scenario

I disagree, ICMP is located in the network layer so tcpdump may not work

I've used tcpdump to analyze ICMP before, so I'm going with A. Maybe the other options are just trying to trick us.

D sounds like the correct answer. ICMP doesn't have ports, and tcpdump does require port numbers, so it wouldn't work for ICMP analysis.

Hmm, I'm not sure. The question says ICMP, so I'm leaning towards C. ICMP is at layer 3, and tcpdump is typically used for layer 4 protocols.

I think the answer is A. ICMP is part of the network layer, but tcpdump can analyze packets at that level.
