Challenge 12: Network Traffic Analysis - No ICMP packets

[stephentyers1975]

Hi,

I'm trying to complete Challenge 12: Network Traffic Analysis and I've used the below command to dump ICMP packets

sudo tcpdump -i eth0 -A -v icmp
tcpdump: listening on eth0, link-type EN10MB (Ethernet), snapshot length 262144 bytes
^C
0 packets captured
0 packets received by filter
0 packets dropped by kernel

I've tried a number of iterations of this command and there doesn't seem to be any ping packets being generated to inspect after leaving it a while. Am I doing something wrong or is the test not generating the ping packets?

Many thanks
Steve

Hello @stephentyers1975
There are packets being sent.
Hint: use ip a and ps -aux

In this scenario, the client tells you that they are sending packets, your task is to analyze all packets.

Happy hunting!

@jleiv01 do you think we need to clarify challenge hints?

We could probably add

"Consider all NICs" or something along those words.
