Snuif (Dutch for sniff) is a very simple packet sniffer for Linux, meant as a demonstration of my understanding and competence in using the C programming language.
Snuif uses simple Unix sockets and doesn't make use of libpcap. Any advanced filtering isn't possible. Instead, Snuif outputs one packet per line, making it able to be parsed with Awk or Sed or whatever.
Enter the repository's root directory and run make. The resulting binary
can be found in the bin folder.
- TCC, but GCC works fine too.
Without any arguments, Snuif will print to standard output.
snuifOne may supply a file path as argument, to which Snuif will then print its output.
