Free defence software for linux

Remake of the old Atari game. You`re controlling defence sattelite on orbin of the Moon. Your goal is to destroy enemy missiles.

In the year 2045 USA built their first base on the Moon. Unfortunatelly, the Moon seems to be a cemetary of the Old Alien Race. The Old Alien Race is really pissed...

Defend your base, soldier!

Seagull project is a multi-protocol traffic generator test tool. Primary aimed at IMS protocols (and thus being the perfect complement to SIPp for IMS testing), Seagull is a powerful traffic generator for functional, load, endurance, stress and performance tests for almost any kind of protocol.
In addition, its openness allows to add the support of a brand new protocol in less than 2 hours - with no programming knowledge. For that, Seagull comes with several protocol families embedded in the source code:
- Binary/TLV (Diameter and many 3GPP and IETF protocols)
- External library (TCAP, SCTP)
- Text (XCAP, HTTP)
Main features:
- Multi-protocol traffic generator
- Protocols of the same family are described in an XML, user editable, dictionary (messages, parameters)
- Existing protocol families: Binary/TLV (Type, Length, Value), Raw binary, Text, external API (first implementation: HP OpenCall SS7)
- Scenarios are described using XML files
- Command line tool with text interface
- Multi-threaded for performances and reliability
- Dynamically adjustable call rate
- Pause and restart of traffic
- Smooth (no new calls then wait for ongoing calls to end) or brutal end
- Scenario display with message counters
- Scenarios have init (executed once), main (repeated for traffic) sections
- Scenarios have default sections for defense in case of unexpected messages
- A scenario can be mono (most cases) or multi-protocol
- Message and parameters checking possible (disabled by default)
- Multiple Seagull instances can be synchronized in the middle of scenario
- Statistics: timer between two messages, call length, call rate, successful calls, failed calls (with reason)
- Protocol decoding and hexadecimal dump
- Trace files with or without timestamps (for performances and automation)
Installation:
To compile Seagull from the source:
- Edit build.conf to fit your needs (default should be OK)
- run "./build.ksh -target clean"
- run "./build.ksh -target all"
- Seagull binaries are in bin/: copy all in /usr/local/bin/
- Add /usr/local/bin in your PATH environment variable
(eg. export "PATH=$PATH:/usr/local/bin")
- Execution environment are in exe-env/XXX-env/, XXX being the protocol
- From there, follow the documentation: http://gull.sourceforge.net/
Enhancements:
- This release adds authentication (MD5/Digest and AKA) for text protocols like HTTP, xcap, and SIP.
- It also adds reconnection in case of LAN failure, configuration parameters for text protocols, two new traffic control actions (pause and resume), and a new protocol family: TLV (Type, Length, Value).

PhishBouncer project is an advanced Java HTTP(S) proxy with anti-phishing capabilities.
PhishBouncer is an anti-phishing platform based on an HTTP/HTTPS proxy integrating anti-phishing checks that do not depend on block lists or Phish signatures. The checking algorithms make use of the attributes of the web-site being visited, the structure and properties of the referring URL, and the web-sites association with other legitimate web-sites that the user interacts with. The checks are implemented as plug-in interceptors, and it is easy to modify them and add or remove new checks. Apart from defense against Phishing, PhishBouncer is also a platform for developing and testing new anti-Phishing checks.
For ease of rapid prototyping and testing of anti-Phishing checks with real and reliable test data, a crawl-and-drive framework is also provided-- all you need is an APWG membership to be able to download Phish Reports from APWG and follow the instructions provided. This framework will periodically download new Phish URLs from APWG, and visit the Phish sites using the PhishBouncer proxy first without and then with the anti-Phishing checks. All results are logged so that dead or broken sites (i.e., sites that produced errors in either visit) can be culled, and the remaining data can be used to obtain an accurate count of how many Phish sites were flagged by the currently active checks.
The HTTP/HTTPS proxy framework can also be used to insert other types of adaptive behavior in the HTTP/HTTPS based interaction by replacing the plug-in interceptors executing anti-phishing checks by other interceptors that performs logging, filtering (as in parental control), load-balancing, QoS-based redirection etc.
PhishBouncer was developed by BBN under an R&D project supported by the Homeland Security Advanced Research Project Agency (HSARPA), under its Cyber Security R&D program.
Main features:
- Implemented in Java, therefore less vulnerable to traditional exploits (e.g., buffer overflow attacks)
- Architectural solution with stronger guarantees than browser plug-ins (can catch phishing attacks even if the browser is closed or not part of the communication)
- Browser independent - supports all web browsers
- Operating system independent - supports all operating systems that can run Java
- Highly customizable deployment options - runs on user hosts, wireless routers, or network server
- Open framework and plug-in architecture - allows easy addition of new checks
- Attribute-based detection - provides protection against unknown phishing attacks
- Supports reactive and proactive anti-phishing checks
- Supports HTTP and HTTPS

Bounce-O-Matic reads through the system log files at a specified time interval (via cron) and finds unwanted attempted logons. Bounce-O-Matic writes these attempts out to an iptables drop file and emits a drop command to iptables.
Bounce-O-Matic is one solution to a common problem, namely, those hammering attacks that occur, at least occasionally, everywhere. The script tries to be as simple and as easy to use as possible while being versatile and extensible.The script was developed with the idea in mind of getting some immediate results from a basic setup of iptables, ssh, and Snort. This way attackus-interruptus can be achieved as soon as possible and the fancy rule development and firewall tweaking can be done at your leisure, or not at all if this script suits the bill.
At the moment the script only checks two log files, but it could do more, and it handles the following cases, but it could do more :
ssh : invalid user login
ssh : failed user login
ssh : root user login
snort : mysql root user login
snort : portscan (log only)
ftp : admin ; administrator login
ftp : root login
Bounce-O-Matic is written in bash. It is not as elegant as it potentially could be, it does not handle connection attempts (only login attempts), it is not a great example of superstar coding, and it probably will not win any prizes for forwarding the causes of world peace or saving the environment, however, it does get the job done!
Once installed, the script needs very little attention, allowing you to go about your business and stop worrying about attackers.
The script aims to be a fire-and-forget type of solution as well as a good solid first line of defense.
Bounce-O-Matic uses commonly available system utilities to accomplish its task.
awk, grep, sort, uniq, date, cat
and makes use of the following other utilities :
iptables :
this needs to be running, or you wont be able to drop anything.
sshd :
as long as the daemon is running, it defaults to logging AUTH to syslog. So even if you dont use Snort, you can still catch the invalid and failed and root user logon attempts that happen here.
Snort :
I happen to be using Snort version 2.3.3 and logging is being directed to the system log facility
output alert_syslog: LOG_AUTH LOG_ALERT
where the above line turns on the output directive in the snort config file.
Enhancements:
- This release adds bounce protection for ftp admin and root login attempts.

Sanvirc is a script for KVirc that includes funtions like: nick identification, autojoin, defense, atack, bots management, away system, etc.
At the moment works whis IRC-Hispano bots but is very easy to adapt to other servers.
Enhancements:
- AutoawayOn y AutoAwayOff
- Sugerencias para el Sanvirc

Yet Another Dynamic Engine (YADE) is an extensible framework that is designed with dynamic libraries in a way that it is easy to add new numerical models and objects.
There are four different models: Discrete Element Method based on spheres, a second method based on tetrahedra, modelling with lattice elements, and Finite Element Method.
Various different methods and algorithms for numerical simulation currently exist. Yade tries to extract their underlying abstractions using following examples:
- Finite Element Method (FEM, [2]),
- Discrete Element Method (DEM),
- Coupling FEM with DEM,
- Mass Spring System,
- Lattice Beam Model,
- Tetrahedron Discrete Model.
Those abstractions are implemented in C++ conforming to Object Oriented design principles. They provide interface to plug-in different modelling methods.
Yade framework is intended to work with other numerical methods than those mentioned above.
Advantages:
- allows numerous simulation methods in the single framework, so coupling them becomes possible,
- plugins can import data from other software,
- thoughtful code design promotes code reuse and improvement,
- open source development model allows community feedback.
Disadvantages:
- implementing models requires adhering to framework design,
- Yade framework is a new emerging software, still in beta phase.
- if you know more disadvantages, let us know!
Enhancements:
- This release has major improvements in the code, and directory cleanup was done.
- The build system was changed from qmake to scons.
- A complete Lattice Geometrical Model was added as a result of PhD defense by one of yades authors.
- Several improvements in Discrete Element Method, capillary law, and triaxial test.
- Among smaller improvements, it is possible to select bodies by clicking them and moving around with the mouse.
- Interaction forces are drawn between bodies, and can be seen as bars with strength related to bar thinckness.

UFO: Alien Invasion is a 3D UFO-inspired tactical game.
UFO: ALIEN INVASION is a strategy game featuring tactical combat against hostile alien forces which are about to infiltrate earth at this very moment. You are in command of a small special unit which has been founded to face the alien strike force.
To be successful on the long run, you will also have to have a research team study the aliens and their technologies in order to learn as much as possible about their technology, their goals and the aliens themselves.
UFO: Alien Invasion is heavily inspired by the X-COM series by Mythos and Microprose. The first game of the series, UFO DEFENSE, became a classic and, in our honest opinion, is one of the best games ever made.
UFO: Alien Invasion is neither a sequel nor a remake of UFO DEFENSE - we simply had the urge to create a similar strategy game, which will hopefully be as entertaining as the original was for the players (and for the developers, of course). Join the IRC-Channel at irc.freenode.org named #ufo:ai and contribute to the developing process.
Gameplay:
The game is turn-based. Well, this might sound somewhat old school now, but trust us: turn-based games are fun!
Each member of your squad has a limited number so called "time units" each round, which are consumed when you order the unit to walk, to fire a weapon or to perform any of the other miscellaneous actions. When all your forces are out of time units, the aliens turn starts. In addition to eliminating as many enemies as possible, your mission is to minimize civilian casualties as well as to acquire parts of the advanced alien technology.
Once youve acquired sufficient samples of the unknown technology, your research labs will be able to reproduce the alien weapons and devices in order to use them against their original creators.
Game Engine:
The game engine is based on a heavily modified version of IDs Quake2 Engine. This doesnt imply that UFO: Alien Invasion is a mod or a total conversion at all! No, UFO: AI is a stand-alone game which doesnt require Quake2 or any similar program to run. Our self-developed game engine is featuring up-to-date OpenGL graphics and special effects, increased texture resolution, hardware accelerated clipping of map layers to toggle between floors, a new animation system for player models, a stunning AI and a few other gimmicks.
Multiplayer support:
You can play UFO: ALIEN INVASION with your friends via LAN or Internet. One player takes the role of the human special squad while the other is in control of the alien invaders. Co-op team play with multiple players on both sides is also supported for up to three teams on each side (6 players total).
Enhancements:
- Implemented sv_roundtimelimit cvar to set the maximum time a team has to finish their round in multiplayer.
- Completely rewritten saving and loading system.
- Finished implementation of Flashbang - now Flashbang will disable enemys reactionfire as well.
- Reintroduced employees renaming again.
- Hire menu and Team Select menu now shows Health bar as well.
- Heavily improved chat subsystem for multiplayer as well as Multiplayer Team Selection menu.
- Improved describing weapons and ammo in UFOpedia and other menus, including displaying firemodes.
- Added multiplayer server password protection.

Three new vehicles:

SPMA (Self Propelled Mobile Artillery)
The SPMA is a two person vehicle, with the driver controlling a long range artillery piece. Alt-fire deploys the spotter camera. Enemies will want to shoot down the spotter camera as soon as they see it, to keep the SPMA from raining destruction from afar. An AVRiL at the spotter camera will automatically re-direct toward the SPMA if it ever becomes visible to the AVRiL.

Paladin
The Paladin is a defense focused vehicle, with a powerful energy projectile cannon and a defensive shield alt-fire. Firing the cannon while the shield is deployed will heavily damage nearby players.

Cicada
The two-man Cicada ground attack bomber is a powerful weapon against ground targets, but is easy prey for Raptors. The pilot can fire missiles, or use the alt-fire to specify a target. While holding alt-fire, multiple missiles are loaded up, and released when alt-fire is released. These missiles will all track toward the specified target location, so the alt-fire can be used to avoid enemy fire while loading up missiles. The second seat in the Cicada is an energy beam turret located on the belly of the Cicada. Its alt-fire is chaff that can be used to confuse incoming AVRiLs.

Six new characters:

Mekkor (Skaarj)
Mekkor is from the Black Fist Clan, sworn enemies of the Iron Skull Clan. Severely injured in battle, he is testing his new cybernetic armor in the Tournament.

Skrilax (Skaarj)
Skrilax is from the Black Fist Clan, sworn enemies of the Iron Skull Clan. Alongside his brother Mekkor, he was severely injured while fighting the Iron Skull Clan."

Barktooth (Iron Guard)
Barktooth would rather rip an opponent to shreds with his bare hands than fight from afar. He also finds close range Flak shots very satisfying."

Karag (Iron Guard)
Before joining the Iron Guard, Karag honed his weapon handling skills during a long stint as a Marshall for the Terran Colonial Authority. His style and panache already have the the Tournament audience abuzz."

Kragoth (Necris)
