Reads a PCAP file and extracts all connections attempted to be made between hosts. It then lists the IP addresses and
   the MAC addresses of all the hosts involved. The results are stored in a file called list_of_connections. 

--- Prints a list of statistics of 5 types of scans made by each host. The scans covered are SYN(Half/Full), UDP, XMAS , RST and ACK. The results are stored in a file called port_scan_stats.

--- Prints a list of confirmed open ports based on the SYN(Half/Full) scan. The results are stored in a file called all_ports

HOW TO RUN:
--- Enter the path of the PCAP file inside the file config.txt.

--- Run the Perl script as follows: perl port_scan_analyze.pl

--- The results will be stored in the respective files as detailed in the FEATURES Section above.
