Rotating per packets receiving by TCPDUMP

Question

How can I use 'tcpdump' command to capture and save each received packets to separate files (having rotatation per packet without losing any packets).

Answer 1

How about saving dump to a file and then splitting that to separate files?

$ sudo tcpdump -c 10 -w mycap.pcap
tcpdump: data link type PKTAP
tcpdump: listening on pktap, link-type PKTAP (Packet Tap), capture size 65535 bytes
10 packets captured

you'll need to have wireshark installed for this to work (e.g. with brew install wireshark on Mac or apt-get on Ubuntu)

$ editcap -c 1 mycap.pcap output.pcap 

10 packets captured -> 10 files created

$ ls -la output* | wc -l
  10
