Free icmp port software for linux

ICMPInfo is a tool that uses ICMP type 13 and 17 to retrieve the current time of a remote host and its netmask.

ICMP-Chat is a simple console-based chat that uses ICMP packets for communication. All the data is encrypted with Rijndael-256 algorithm.
Installation:
Type: make && make install
For solaris type: make solaris && make install
Usage:
Usage: icmpchat [OPTIONS] < host > < nick >
< host > = Host to chat with
< nick > = Your nickname
OPTIONS:
-t < type > = specify icmp type (default ECHO_REPLY)
Example: icmpchat 192.168.1.2 foo
ICMP codes:
[0] Echo Reply
[5] Redirect
[8] Echo Request
[9] Router advertisement
[10] Router solicitation
[13] Timestamp request
[14] Timestamp reply
[15] Information request
[16] Information reply
[17] Adressmask request
[18] Adressmask reply
Enhancements:
- Rewrote from scratch
- Implemented optimized rijndael algorithm
- Implemented sha256 for password hashing
- Implemented ncurses frontend (again)
- Fixed getuid problem so that setting suid flag works now (thanks John)

C-Dogs SDL is a port of the old DOS arcade game C-Dogs to modern operating systems utilising the SDL Media Libraries. In theory C-Dogs SDL should be able to run on Windows, MacOS X, BeOS and the other systems supported by SDL.

Genererally, the more UNIX like a system is, the greater the chance of C-Dogs working (MacOS X and BeOS people, I mean you guys).

C-Dogs SDL was ported to SDL by Jeremy Chin and Lucas Martin-King, using Gentoo Linux as their development environment.

C-Dogs is an arcade shoot-em-up which lets players work alone and co-operativly during missions, and against each other in the "dogfight" deathmatch mode. The DOS version of C-Dogs came with several built in missions and dogfight maps, this version is no exception.

The author of the DOS version of C-Dogs was Ronny Wester. See the "official" homepage for more details. We would like to thank him for releasing the C-Dogs sources to the public.

Tennix! SDL Port is a simple two-player tennis game.

It features simple image loading (with all game graphics being customizable by simply editing them with a graphics editor like The GIMP), sound effects, stadium audience sounds, and ball shadows.

The source code for this SDL port is released under the terms of the GNU General Public License, Version 2 (or later).

Controls

Player 1 uses the keys W, S and D and Player 2 uses O, L and K.

Shell over ICMP consists of two free and open source applications: one server and one client. Shell over ICMP project allows a user to connect to a remote shell daemon, by using ICMP protocol instead of classical TCP.
Entirely written in Python, soicmp is a working proof-of-concept to demonstrate that data can be transmitted across a network by hiding it in traffic that normally does not contain payloads.
How does it work?
The soicmp server is a daemon that must be started on the remote server. When the server receives a request from the client it looks into the packets payload. The payload must respect certain protocol rules. In detail the client must specify:
command
communication mode (echo|echo/reply)
authentication (y|n)
This is an example of a correct payload string sent by client to server:
$CMD ls -a $MODE echo/reply $PWD root2005 $END
If the payload matches with the server protocol specification then it will pipe the command to "/bin/sh" or "cmd.exe" and execute it. The server then reads the result from the pipe and sends it back to the client that will print it to stdout.
Moreover every client will send ICMP packets having id equal to the clients current process ID and will accept only ICMP replies having the same id value. This prevents output to be printed by other client instances running on the same workstation (this argument is also treated in the FAQs section).
Main features:
- Platform independent.
- Possibility to run soicmp daemon on multiple ethernet interfaces simultaneously handling multiple client connections.
- Possibility to specify the buffer size of outgoing packets.
- Client side source IP address spoofing.
- Remote client case-sensitive (plain texted) authentication.
- Possibility to select two communication types:
- One based on encapsulating command output in unique "one way" ICMP_ECHOREPLY (type 0) packets sent by server to client (see fig. 1).
- Another one that guarantees the correct packets delivering by using the request/response nature of ECHO and ECHOREPLY ICMP packet types (see fig.2)
- No listening sockets are listed by netstat or similar programs.

Coarse Port Knocking is a simple implementation of the port knocking techniques.
This program uses the ngrep tool to sniff blocked network packets. It waits for special packets with determined keys and executes commands like a firewall to open and close ports.
Enhancements:
- A bug in injection mode has been fixed.

The ICMP Hostname Tools for Linux include a responder daemon, a lookup tool, and a nameswitch module to handle ICMP host name functions.

The NSS module caches all requests (including failures) and honors the TTL value sent by the responding host. It uses a configuration file called /etc/nss-icmp.conf, which controls different aspects of its operation:

* timeout – Sets the timeout in milliseconds for ICMP host name queries, by passing the -t option to idnlookup.
* nocache – Disables the cache.
* ttlnotfound – Sets the TTL for not-found cache entries is seconds. The default is 5 minutes.

Both icmpdnd and idnlookup need to run as root, due to the fact that they use ICMP. Thus, idnlookup needs be installed SUID root.

CppUnit is a C++ unit testing framework. CppUnit project started its life as a port of JUnit to C++ by Michael Feathers.
Main features:
- XML output with hooks for additional data
- Compiler-like text output to integrate with an IDE
- Helper macros for easier test suite declaration
- Hierarchical test fixture support
- Test registry to reduce recompilation need
- Test plug-in for faster compile/test cycle (self testable dynamic library)
- Protector to encapsulate test execution (allow capture of exception not derived from std::exception)
- MfcTestRunner
- QT based graphic test runner
