This program takes as input a PCAP file and extracts the different network layer headers and prints them out in a csv format. The output is printed in the terminal.

Compile the program:

$ gcc feature_extract.c

run the program. The program requires as argument the path to the pcap file:

$ ./a.out ../Input.csv

The output will be printed on the terminal which can be redirected to an output file:

$ ./a.out ../Input.csv >> output.csv

call the script as follows:

tshark_script.sh file.pcap >  output.csv

where file.pcap is the input .pcap file.
