Free communication suite software for linux

Meldware Communication Suite is a platform independent groupware package consisting of:
Meldware Mail
Meldware Calendar
Meldware Webmail
Meldware Secure Administration System
Together the package provides support for thousands of users to concurrently send and receive email and schedule meetings. MCS uniquely allows you to store all messages and scheduling events in nearly any database and runs on nearly all popular software and hardware platforms.
Additionally, while the scheduling and calendaring services are able to be installed separately, the integrated featureset provides both a unique and powerful experience to both users and server-side Mail Based Applications and Collaboration Based Application Services.
The MCS platform provides security integration using LDAP sources including Microsoft Active Directory as well as flat-file and Database sources. Additionally, extensible security allows custom authentication/authorization sources.
Enhancements:
- IMAP is now stable with Mozilla Thunderbird and POP/SMTP are production ready.
- New Filestore code was implemented and many improvements were made in mailbox and storage code.

SAP R/3 Communications Suite allows SAP R/3 servers to communicate with external devices such as fax and GSM modems by sending and receiving a fax or SMS.

SAP R/3 Communications Suite provides an easy configuration through a Web interface and a JMX console.

Soma is a suite of programs that let you play and schedule audio files from the Web.
Soma suite supports extra utilities using run-time loadable modules and includes a broadcasting scheduler, a tool to control it via TCP/IP, and an utility to check configuration file syntax.
Soma project started in summer 2003 to manage the digital version of an activists radio old spools.
The first release just gave just the chance to play random some audio files in a directory using an external program (at that time mpg123). In despite of that this software was never used, i kept on thinking about soma project for some weeks, until i started directly to work with a group called Reload, which was experimenting at the time a project called "eterete" and creating a place for a web radio at Pergola Tribe (a selfmanaged house in Milan).
We used, of course, a release, which was a little bit better to manage the radio-playlist and of course we implemented the software itself. From september till december soma became a software suite, configurable through file and (remote administration...). Thats thanks to the relationships and the inputs that such a community like Reload can create.
A group of passionate activists was able to make broadcastings and broadcast schedules, to find out new problems and to give implementation advices. They also suggest me the idea that soma (originally a simple play-list manager) could become a programs suite, which has a player, a software for deferred broadcasting, a more user friendly admininstration, documentation and distribution.
Some time after came somaplayer and somaadmin. The player was still very behind compared to my implementation ideas. Somadmin was straight away on line and advertised on radio.inventati.org/somadmin/
In January 2004 we showed Soma at the first italian (web and air-waves) radio meeting in Naples.The meeting was technologically and politically profitable and it was an attempt to build up a real radio-network.
Radio.inventati.org was actually the only example od direct cooperation among even very different people: individuals, improvised groups, very old and movement radios and experiences from overseas countries.
On the web site there are occasional streamings, weekly streamings, and 24hrs music flows.
The object of the technical research was a digital environment, which could let individuals or whole communities gain access to a common schedule with resum?s, repetitions, deferred programs, live broadcastings, regular broadcastings as one national and international network.
Soma could satisfy this need and could be easly managed through the web thanks to somadmin, which could update the soma admin in real time.
The developments went on. Somaplayer is now reality. The only music player which can stream directly an mp3, an ogg vorbis, a wav, a track from an audio cd or a streaming directly on an icecast server (icecast 2 or shoutcast) or just play it on a computer using sound drivers or sound daemons.
At the moment more other people work at this project, who debug the software, write docs, work at the website and make installation packages (for debian).
Enhancements:
- This release fixes three bugs related to group permissions, the 31st of months, and an error in libsoma related to buffers and protocols.

Openwall tcb suite package contains core components of our tcb suite implementing the alternative password shadowing scheme on Owl.

It is being made available separately from Owl primarily for use by other distributions. Note that you need to have the password hashing framework introduced with crypt_blowfish patched into glibc to compile and use this.

The package consists of three components: pam_tcb, libnss_tcb, and libtcb.
pam_tcb is a PAM module which supersedes pam_unix. It also implements the tcb password shadowing scheme.

The tcb scheme allows many core system utilities (passwd(1) being the primary example) to operate with little privilege. libnss_tcb is the accompanying NSS module. libtcb contains code shared by the PAM and NSS modules and is also used by user management tools on Owl due to our shadow suite patches.

Asterisk Manager Suite (AMS) is a collection of software; an abstraction library called Asterisk Manager Interface (AMI), a proxy daemon called Asterisk Manager Proxy (AMP), and a gui client interface called Asterisk Manager Administrator (AMA).
The intention of the software is to make management and administration of the Asterisk Open Source PBX easier. The software is currently targetted at corporate environments with call centers but plans for further expansion exist.
The C library, libami (AMI) is intended to make executing commands through Asterisks Manager Interface easier. The library is used extensively in both AMP and AMA, although you could use it in your own software as well.
The proxy daemon is intended to remedy an outstanding issue with Asterisks Manager Interface: The interface does not deal well with excessive connections. To get around this, a proxy is a suitable solution. As well as simply being a proxy, AMP has other functions as well, including recording statistics and activities of call center agents.
AMA is intended to be a gtk application for monitoring and administrating an Asterisk server. AMA requires AMP for connectivity and has many functions as well as some planned in the future. AMA was first inspired by Asterisks own gastman client, which was well done, but to small to be of any real use to anyone in a corporate environment except perhaps admins.
Enhancements:
- Minor bugfixes dealing with ampd not sending events properly.

TAHI Test Suite provides a mechanism for validating an IPv6 implementation against a standardized test for conformance to the IPv6 specification, extensions and directly related protocols.
TAHI Project is the joint effort formed with the objective of developing and providing the verification technology for IPv6.
The growth process of IPv4 was the history of encountering various kinds of obstacles and conquering such obstacles. However, once the position as infrastructure was established, it is not allowed to repeat the same history. This is a reason why the verification technology is essential for IPv6 deployment.
We research and develop conformance tests and interoperability tests for IPv6.
We closely work with the KAME project and USAGI project. We help activities of them in the quality side by offering the verification technology we develop in the TAHI project and improve the development efficiency.
We open the results and fruits of the project to the public for FREE. Any developer concerned with IPv6 can utilize the results and fruits of TAHI project freely. A free software plays an important role in progress of the Internet. We believe that providing the verification technology for FREE contributes to advances of IPv6. Besides the programs, the specifications and criteria of verification will be included in the Package.
Enhancements:
- This release extends the tests in the specification and code.
- There are assorted minor bugfixes.
