Here is a script that can use tshark to split a large pcap to multiple small pcaps
inpcap="test.pcap" max=$(tshark -r $inpcap -n -T fields -e frame.number|tail -1) # This is the number of packets in each split pcap c=1 # Save all new pcaps to out, if it does not exist, create it. [[ ! -d out ]] && mkdir out for i in $(seq 1 $max $c) do tshark -r $inpcap -n -c $c "frame.number==$i" -w out/$i.pcap #Do other stuff, if required read -p "Send the next packet? " done
A very simple 3-4 line script that has saved my day so may times.
Edit: I found a nice tcpdump cheatsheet https://comparite.ch/tcpdumpcs
