DNSA 0.5

DNSA and DNSA-NG are swiss knife tools for Linux designed to test several DNS security issues.
DNSA and DNSA-NG are swiss knife tools for Linux designed to test several DNS security issues.

The most important one is a full wifi support using 2 cards:

- The first in monitor mode which capture 802.11 traffic
- The second associated to the AP and injecting DNS forged packets

Host-ap and madwifi drivers are already supported by DNSA-NG.

DNSA was initially thought because of a lack in DNS auditing tools. It uses libnet and libpcap :

"Libnet is a high-level API (toolkit) allowing the application programmer to construct and inject network packets. It provides a portable and simplified interface for low-level network packet shaping, handling and injection. Libnet hides much of the tedium of packet creation from the application programmer such as multiplexing, buffer management, arcane packet header information, byte-ordering, OS-dependent issues, and much more.

Libnet features portable packet creation interfaces at the IP layer and link layer, as well as a host of supplementary and complementary functionality. Using libnet, quick and simple packet assembly applications can be whipped up with little effort. With a bit more time, more complex programs can be written (Traceroute and ping were easily rewritten using libnet and libpcap).
