using kali linux and TCPDUMP, finding commands to apply the below with an existing pcap file.

Start by creating a Python pcap analysis program with the ability to loop through all of the packets of the trace. Each packet in a pcap trace is preceded by a header as de$$ned in pcap$\_$pkthdr$.$ This header contains a UNIX timestamp, among other $$elds$.$ To iterate through all packets of the trace, you may wish to use, in C$,$ pcap$\_$loop$()$ or pcap$\_$dispatch$()$ with the appropriate callback $($you must create the callback$).$ With python$$s dpkt$,$ pcap.Reader provides a similar iterator. Answer the following questions:

$1.$ How many packets does the trace contain?

$2.$ What is the average tra$$c rate $($in bits per second$)$ of the trace$4?$
