A packet dissector driven by machine learning algorithms. You train it to recognize specific types of packets by showing it examples and counterexamples of some packet type, and it will figure out which bits in the packet define it as the type you seek.
Extend the functionality of the mount and the umount commands by adding support for basic device mapper devices, for key files and scripts and for filesystem checking at mount time while retaining support for loop device encryption.

FrozenFS aims to be a complete implementation of an immutable file system on unix-like systems. FrozenFS tries to emulate on unix-like platforms the functionality provided by Deep Freeze for the Windows platform.
Mod_auth_kerb is a module that provides Kerberos user authentication to the Apache web server. It allows to retrieve the username/password pair, and also supports full Kerberos authentication (also known as Negotiate or SPNEGO based authentication).
The kernel network stack may behave not as expected, especially in the case of receiving packets. With Ianus it is possible to bypass the kernel network stack and to develop your own network stack in user space or other tools.
SING stands for 'Send ICMP Nasty Garbage'. It is a tool that sends ICMP packets fully customized from command line. Its main purpose is to replace the ping command but adding certain enhancements (Fragmentation, spoofing,...)
A tool to monitor internet hosts` bandwidth usage in a Linux-NAT network. A daemon collects data and clients display them (currently a Java applet with a graph). It automatically detects new hosts and has a nice summary statistic.
Portscan is a simple TCP port scanner (connect scan, similar to nmap -sC).
It is implemented with threads for better speed.
Please see the code and review it. Criticism is more than welcome.
Helps needed to make it robust.
