Free garage door openers software for linux

The doorman guards the door of a server, manipulating firewall rules to admit only recognized parties.
The doorman is intended to run on systems which have their firewall rules turned down tightly enough as to be effectively invisible to the outside world. The doorman adds and removes extra rules in a very controlled manner.
Using metaphor 1...
The doorman daemon "guards the door" of a host, admitting only recognized parties. It allows a server which is not intended for general public access to run with all of its TCP ports closed to the outside world. A matching "knocker" is provided, with which to persuade the doorman to open the door a crack, just wide enough for a single TCP connection from a single IP address.
And now, switching to metaphor 2... :)
A private server thus rigged for silent running has greatly enhanced security. Port scans cannot reveal its existence. Even if its existence is known by other means (or the firewall isnt all that tight), possible bugs in server code cannot be exploited; packets from unknown sources simply never get to the bug.
The current implementation of the doorman, "doormand", is suitable for protecting only TCP services on Unix-type systems. The door-knocker, "knock", can be run under Unix, GNU/Linux, or Microsoft Windows.
The doorman is based on an original idea of Martin Krzywinski, who proposed watching firewall logs for a sequence of packets directed to closed ports, which method he described in Sysadmin magazine and linuxjournal.com.
You might also visit his pages at www.portknocking.org.
This particular implementation deviates a bit from his original proposal, in that the doorman watches for only a single UDP packet. To get the doorman to open up, the packet must contain an MD5 hash which correctly hashes a shared secret, salted with a 32-bit random number, the identifying user or group-name, and the requested service port-number.
Enhancements:
- Added support for linux cooked socket header len; thanks to Markus Hoffmann.
- Fixed guestlist hostname-parsing bug; also thanks to Markus.
- Changed method of remembering old knock hashes, without use of Berkeley DB.
- Kinda-fixed a bug handling pcapnext-returns-null condition. I hope.
- Included lexer.c (flex output from lexer.l) in distribution. Duh.
- Fixed doorman bug when creating new new hashfile; thanks to Robert Koropcak
- No changes made to knock.c; however, it will report being V0.81

trackpeer is an agent program that helps network and server administrators with tracking users computers.

It makes it possible to determine the MAC addresses of computers over a network, even when the computers are behind NATed gateways.

This agent program is intended to be used by the administrators who need to identify and locate malicious computers (users) and virus-infected computers in a network such as middle-sized Wireless LAN system, public ethernet jack system, and campus or corporate network.

The program will also be useful for a simple MAC-address-based authentication over a network.

Using MAC addresses has several advantages over other computer/user identification methods, since every ethernet interface has its unique MAC address that cannot be changed easily in many cases.

The agent program has two features, MAC address informing and MAC address logging.

`trackpeerd and `trackpeer are an agent program and a simple client program, respectively. The agent program should run on a gateway (or a packet capturing machine beside it) which resides in the same network segment as the client computers are. We call the router ``frontline router. The agent listens to the communication through the router and caches packets header information.

The client program trackpeer is used when an administrator or a server program would like to know the MAC address of a specific peer, just after a communication action is taken by the peer.

trackpeer provides the agent with the source/destination addresses of a packet, the port numbers of the packet, and the time of the packets arrival. The agent looks into its internal cache memory, picks up the address information that matches the query, and provides the server with the information.

In other words, the server asks the agent,
`` Whos knocked the door at around HH:MM.SS? .

The agent will forget the address information after a certain period of time (10mins) has passed.

CalcRogue project is a Rogue-like for calculators, Palm, and PCs.
CalcRogue is based on the Unix game Rogue and those similar to it, collectively known as "roguelikes". They involve a character which can move around, attack monsters, collect magical items, maybe cast spells, and gain levels.
The dungeons are randomly generated, so the areas are always fresh, and the difficulty is such that it never gets too easy. (Note: CalcRogue is not derived from Rogue.)
Main features:
- Complex, randomly generated levels
- Overworld map, towns, and quests
- Spells and magically summoned minions
- Easy to use interface with tutorial
- Line of sight/lighting calculation
- Four-color grayscale graphics
- Complete inventory management system
- Wide variety of magical scrolls, potions, wands, rings, amulets and spells
- Missile combat with bows, crossbows or thrown potions
- Compressed saved games

Prey tells the story of Tommy, a Cherokee garage mechanic stuck on a reservation going nowhere. His life changes when an otherworldly crisis forces him to awaken spiritual powers from his long-forgotten birthright. Abducted along with his people to a menacing mothership orbiting Earth, he sets out to save himself and his girlfriend and eventually his planet.
Prey is serious, dark story, based on authentic Cherokee mythology. Themes of sacrifice, love and responsibility are explored and the story dives into emotional territory not yet explored by similar games. You will find nothing familiar with this game.
Overview
In Prey, gamers enter an unpredictable world where nothing can be taken for granted. Most of the game takes place within a living ship, a giant entity that can sense and react to Tommys presence.
Prey makes use of Josephs Campbells renowned story structure, "The Heros Journey," for guiding the main character arc. Campbells extensive work on mythological story progression was made famous when George Lucas used it for Luke Skywalkers story arc in the original Star Wars.
Main features:
- Built on an enhanced Doom 3 engine, the most impressive 3D engine used in a released game.
- Portal technology adds a new dimension to gameplay, allowing enemies to appear out of thin air and create new and completely original puzzles and gameplay styles.
- Several never-before-seen gameplay elements such as Spirit Walking, Wall Walking, and Deathwalk.
- Highly organic, living environment that itself can attack Tommy.
- A deep, emotional story of love and sacrifice.
- Tommy has a sidekick, a spiritual hawk that can help him fight enemies and decipher the alien language of the living ship.
- Multiplayer game support that takes advantage of the unique gameplay styles in Prey.

RogueScanner project is an open-source vulnerability management tool that is used to gain greater network visibility to enable you to quickly identify and remove rogue wireless devices that may provide a back door to access your critical data and infrastructure.

Considering that rogue access points and peers represent a major threat to data integrity, RogueScanner is a valuable tool that you can start using today at no cost.
More than 300 companies manufacture access points, and there are more than 10,000 different models of network infrastructure.

Companies thus face a major challenge in maintaining a system to track and identify all potential rogue wireless devices and in continually scanning the network to identify them. To address this challenge, Network Chemistry has made an open-source product available to help organizations begin to immediately scan their networks.

RogueScanner is available for use at no charge by organizations looking for a tool focused on device identification and rogue detection. RogueScanner leverages the Collaborative Device Classification system to automatically lookup and identify the device type and its identity in real time.

Whats New in This Release:

+ Reserved VLANs (1000 < VLAN < 1025) on Cisco devices are not queried.
+ Capture packets to trace.pcap and perform a hexdump of them in the log file
if DEBUG_PACKET is set (debug=0x01 or better).
+ Promiscuous mode testing is disabled unless ENABLE_SCAN_PROMISC is defined.
+ The switch/network scanning interval was bumped up to 24 hours.
+ Attribute data in the EvidenceMap wasnt being printed out correctly (always showed
up as "true") when issuing "device detail" commands in the CLI.
+ Ignore MACs in the bridge table that arent "learned" when querying switches.
+ *TAnalysisManager::LookupOrCreateDevice() will now refuse to create devices outside
"home_net" ranges, thus the IPs wont be scanned even if they are passively observed
on the local network.
+ Ignore our MAC address if a switch reports it to us.
+ Log timestamps are now in GMT.
+ Prevent duplicates in the "udp_ports" evidence by using AddEvidence() instead of
inserting into the EvidenceMap directly.
+ Manually invoke Rubys garbage collector after scanning a switch/router.
+ Added "packet queue size" CLI command to show how many packets are in the
AnalysisManagers packet queue.
+ If a device fails to be classified the classification will be retried automatically
in one minute.
+ All communication with the classification server is performed in a separate thread.
+ Keep ARP scanning from starving other threads for CPU time by introducing a delay
in addition to any that is added by bandwidth throttling.
+ Replaced internal ARP and routing table on WIN32 systems with functions from the
IPHelper API.
+ Added "device list size" command to show how many devices have been found.
+ Add read community strings from configured infrastructure devices to the list
of strings used when probing unknown devices.
+ Discard deferred scans if another scan of the same type is already deferred for
a device.
+ Added reporting of DHCP data.
+ If no scans are pending against a device, but a new port is found open then
submit the devices evidence.
+ Devices are re-scanned whenever a re-occuring ARP/Ping scan is launched.
+ Added "deferred list" CLI command to show scans that have been deferred.
+ Added "sniffer status" CLI command to report the number of packets that
have been received and dropped.
+ If we discover the IP of a device that we only knew about the MAC address for,
then issue scans against it.
+ If we see the MAC address associated with an IP change, then re-scan it since
its likely to be a different device.

barricade is a simple implementation of the door knocking method aimed to open your network service or firewall only if a special ICMP echo request packet is sniffed from the network interface. After the last valid packet received, barricade waits for a defined amount of time, then it closes your firewall or stops your services. There is a client included in the package called barricade_client that helps you to create special icmp packets containing the system password.
To compile barricade you need gcc and libpcap headers (>= 0.6.2). Simply run
make
to compile the program and
make install
to install. Installation paths are defined in ./scripts/install.sh. This script is suitable for debian users (and perhaps for many other distros) but you may need to edit some parameters. Dont forget to edit uninstall.sh to reflect changes made on install.sh if you plan to uninstall barricade. ./etc/barricade.conf is a sample configuration file, with comments. Edit this file to suit your needs and put it on /etc/.
Enhancements:
- per-ip command mode
