Bomb them down to the ground with one finger
Gnome Attacks is a Gnome 2 game where you bomb cities into oblivion in order to make a flat surface for your rapidly-losing-height spaceship to land.
It is extremely accessible since you can control it "simply using one finger."
The current release allows you to flatten Londons most famous landmarks!
How to play:
- To Start: open a terminal and type "gnomeattacks" and then RETURN. Thats it.
- Keys: press any key to drop a bomb. Thats it.
- Objective: bomb all the buildings down to the ground. Thats it.
Enhancements:
- linc
Enhancements:
- A new level set using real photos of London was created.

The Port Scan Attack Detector (psad) is a collection of three system daemons that are designed to work with the Linux Netfilter firewalling code to detect port scans and other suspect traffic.
Port Scan Attack Detector project features a set of highly configurable danger thresholds (with sensible defaults), verbose alert messages, email alerting, DShield reporting, and automatic blocking of offending IP addresses.
Psad incorporates many of the packet signatures included in Snort to detect various kinds of suspicious scans, and implements the same passive OS fingerprinting algorithm used by p0f.
Enhancements:
- A --gnuplot mode was added so that psad can output data that is suitable for plotting with gnuplot.
- The ability to negate match conditions on fields specified with the --CSV-fields argument was added.
- The Storable-2.16 module was added along with the --use-store-file argument so that in --gnuplot mode the Gnuplot data can be stored on disk and retrieved quickly.
- --analysis-fields was added so the iptables log messages that are parsed in -A mode can be restricted to those that meet certain criteria.

Crack Atack! is an OpenGL game based on the Super Nintendo classic Tetris Attack.

You can swap only two bricks. Put at least 3 together to explode them.

pkcrack is an implementation of a known plaintext attack on password encrypted ZIP archives. For the attack to be successful you have to have at least 106 bytes of unencrypted compressed data from the given ZIP archive (the data must be compressed using the same compression method as the encrypted counterpart). Providing this, the sophisticated attack can be thousand times (or even more) faster than a brute force attack (considering non-trivial long password). The speed is affected by the amount of plaintext you transmit.
Enhancements:
- "Relf" has found and fixed a bug that caused pkcrack to fail under certain circumstances (roughly one out of 32 keys couldnt be found). Thanks!
- Two more options for pkcrack, also by "Relf" (Thanks again!): -a will stop stage2 immediately when a combination of key0, key1, key2 has been found -n disables the (new!) progress indicator
- corrected handling of data descriptor in extract-functions (Thanks to "Relf" and Andreas Lessig !)
- zipdecrypt now uses dynamic allocation for directory entries, which means the 200 files limit is gone
- The extract program now has a -v flag to print a verbose description of the ZIP file
- Considerable speedups in stage1
- The source distribution now includes an automated test suite

Crystal Core is the main Crystal Space demo game. The project makes heavy use of CEL and CELstart. It is going to be a first person shooter with many quests and puzzle elements. The three main purposes of Crystal Core are:
