Working:

• Reads a set of packets and produces a detailed summary of those packets. This program can run as a shell command. The syntax of the command is the following: % java pktanalyzer datafile
• The pktanalyzer program will extract and display the different headers of the captured packets in the file datafile.
• First, it displays the ethernet header fields of the captured frames.
• Second, if the ethernet frame contains an IP datagram, it prints the IP header.
• Third, it prints the packets encapsulated in the IP datagram. TCP, UDP, or ICMP packets can be encapsulated in the IP packet.
