Pcap Analyzer

Description

This is a small C program that takes a pcap file as input and displays, at 10-second intervals, a list of IP addresses appearing in the pcap packets along with the number of times they appear. The output is sorted by the frequency of appearances.

How to Compile

To compile the program, use a C compiler. For example:

gcc pcap_analyzer.c -o pcap_analyzer -lpcap

Dependencies

PCAP library : if not already installed, install it using your system's package manager.

Example on debian:

sudo apt-get install libpcap-dev

TODO

  • Utiliser un dictionnaire avec allocation de mémoire dynamique plutôt qu'un tableau statique
  • Ajouter TU
  • Mettre les fonctions relatives au fichier PCAP et relatives au tri dans des fichiers .c et .h séparés (et ajouter static au fonction locales)
  • Prendre time de wireshark plutot que le timestamp epoch précis à la seconde près seulement
