To compile: run make

To run: sudo ./sniffer

The sudo is necessary to use the network card in promiscuous mode, otherwise, only networks without need to run in promiscuous mode will be shown (e.g., bluetooth).

To stop the capture: ctrl + z.

The program prints the captured packets on screen and produces three files (its name must be entered by the program):

• pcapfile.pcap: A file in the pcap format, ready to be used with Wireshark or other similar softwares.
• raw_logfile.txt: A file with the raw output of the captured packets, containing the content in hexadecimal and in string format.
• logfile.txt: A file with the log of the captured packets showing some content inside it.

At the end of the program, the user will be asked if wants to merge the files raw_logfile.txt and logfile.txt.
