Free instant messaging software software for linux

Akeni Instant Messaging - Pro is a client/server instant messaging platform that allows companies to host their own secured private IM system. The client has an user interface similar to AIM, ICQ, or MSN Messenger. It supports all the standard IM features such as chat, group conference, presence management, file transfer, offline messages and emergency alert/notification. Extra features include contact management and optional tabbed chat sessions.

The server has administration tools like managing user accounts, client-side logging capabilities and peer-to-peer file transfers. Akeni Pro Messenger can be setup on a private network without connecting to the internet and can easily be setup for use inside and outside the company firewall.

XPA Messaging provides seamless communication between Unix programs, including X, Tcl/Tk, and generic select() loops. XPA Messaging provides an easy way for users to communicate with these XPA-enabled programs by executing XPA client commands from a shell.
Because XPA works both at the programming level and the shell level, it is a powerful tool for unifying any environment, offering flexibility in choosing the best level at which to access XPA services.
A program becomes an XPA-enabled server by defining named points of public access through which data and commands can be exchanged with other client programs (and users). Using standard TCP sockets, XPA supports both single-point and broadcast messaging to and from these servers.
Enhancements:
- Ported to Intel icc and gcc 3.3 compilers.
- Upgraded to Tcl/Tk 8.4.
- Support has been added for generating man pages, PDF, and Postscript from the HTML pages.
- Potential buffer overflows in string handling have been fixed.
- There are numerous other bugfixes.

Lua Messaging Engine (LuME) is a set of scripts that offer abstract functions for communication via AOLs OSCAR protocol (as used by ICQ and AIM clients), Microsoft Messengers MSNP, and Yahoos YIM protocol. Lua Messaging Engine also includes utility functions for string operations, SHA hashing, and basic HTTPS communication.

An increasing number of software developers are making use of the simplicity and power behind employing a Lua script interface.

Meetroduction, LLC has been using a Lua script interface as a core design concept for the multi protocol messaging component of its proximity based people finder client: Meetro. Beyond that, the interface offers its users a flexible way to vastly extend the clients functionality.

Fast Messaging Peer to Peer (FM P2P) is a simple P2P program that forms a TCP-based overlay network by which a user may chat or share files.

Why name this FastMessaging when its anything but fast? Simply put, it is a reference to the underlying functioning of the application. TCUP, the protocol used to do the overlay network (the network we build ontop of an existing TCP/IP network) is message based.

We think it is Fast because there is no queueing or long searches. FastMessaging is built to construct moderately sized networks which have reasonably high responsiveness at the cost of global information sharing.

Perhaps thats not the best reasoning, but it works. Its just a name and the application needs a better name anyway. For now I just refer to it as FM.

Instant is a Python module that allows for instant inlining of C and C++ code in Python. Instant is a small Python module built on top of SWIG.

Example of use:

>>> c_code = """
double sum(double a, double b){
return a+b;
}
"""
>>> import Instant
>>> ext = Instant.Instant()
>>>
>>> # create the wrapper code, compile and link it to a shared library
>>> ext.create_extension(code=c_code, module=test1_ext)
>>>
>>> # use the C code
>>> from test1_ext import sum
>>> print sum(3.7, 4.8)
8.5

Example with NumPy arrays converted to C double arrays:

>>> import Instant
>>> import Numeric
>>> import sys
>>> import time
>>>
>>> ext = Instant.Instant()
>>>
>>> c_code = """
/* add function for vectors with all safety checks removed ..*/
void add(int n1, double* array1, int n2, double* array2, int n3, double* array3){
for (int i=0; i >>"""
>>>
>>> ext.create_extension(code=c_code, headers=["arrayobject.h"],
>>> include_dirs=[sys.prefix + "/include/python" + sys.version[:3] + "/Numeric"],
>>> init_code=import_array();, module=test3_ext,
>>> arrays = [[n1, array1],[n2, array2],[n3, array3]])
>>>
>>> from test3_ext import add
>>> a = Numeric.arange(10000); a = Numeric.sin(a)
>>> b = Numeric.arange(10000); b = Numeric.cos(b)
>>> c = Numeric.arange(10000); c = Numeric.cos(c)
>>>
>>>add(a,b,c)

Instant-Grid is a live-CD based on Knoppix bundled with a pre-configured grid environment based on the Globus Toolkit.
One PC started from this CD becomes the Instant-Grid frontend. It also functions as a PXE boot-server, allowing other PCs in the same local network to boot the Instant-Grid environment.
Together with the frontend, these PCs automatically form a working test grid. Like with the original Knoppix, the existing configuration of the participating PC is not touched (except maybe for enabling the PXE boot-option), and remains instantly available by a simple reboot.
Enhancements:
- This version has a newly designed user interface improving its accessibility for beginners, which is further enhanced by new flash videos showcasing the most important features.
- Also new is the integration of the graphical workflow manager GWES.
- Its capabilities are demonstrated by a demo version of ERAMAS, an environmental simulation tool, and by a new POV-Ray renderfarm based on workflows.
- Furthermore, it is possible for the first time to use external resources, which requires a D-Grid certificate.

Yahoo! Messenger for Unix sends instant messages to your Windows and Unix friends!
Enhancements:
