I'm attempting to run a tcpdump for packet capture for the headers of encrypted traffic. I'm trying to do it with the rotating capture based off time. This is the command I'm running.
sudo tcpdump -nnSvvtttts 300 -G 600 -i eth0 -w /home/onion/tcpdump/encrypted_
I've cut the -G to 10 in an attempt to create a new file every 10 seconds just to verify it's working but I still only end up with one file. Am I misunderstanding the -G man page or is it something I'm missing?
