Faking DNS from userland

To give false DNS responses from userland we need to handle different type of syscalls : gethostbyname(), gethostbyname2(), getaddrinfo(), getnameinfo(), etc. To cover all these cases, and to prevent leaks to real dns servers, we will use two libraries : libresolv_wrapper and libnss_wrapper.

Installation

Install resolv_wrapper and nss_wrapper, either from sources or from your favorite Linux distribution.
