Beyond the Command Line

---

The isic and nemesis tools provide a complete set of functionality that can be rapidly thrown into shell scripts, Perl routines, or single command lines. They also remove the hassle of debugging a custom C or C++ program since variable handling, memory pointers, and network addressing are handled out of the user’s sight. On the other hand, you also have the option of delving into the guts of these programs and writing your own packet creation routines based on the libnet or libpcap libraries.
