Free adaptive communication 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.

Ice, the Internet Communications Engine, is middleware for the practical programmer. A high-performance Internet communications platform, Ice includes a wealth of layered services and plug-ins. Ice means simplicity, speed, and power.
Ice is available under the terms of the GNU General Public License (GPL). Commercial licenses are available for customers who wish to use Ice with proprietary products. Please contact sales@zeroc.com for more information.
Ice is currently available for C++, Java, C#, Visual Basic, Python, and PHP, and is supported on various operating systems. Additional operating systems and languages will be supported in future releases.
Ice consists of the following packages:
Slice The Specification Language for Ice. Slice establishes a contract between clients and servers, and is also used to describe persistent data.
The Slice Compilers Tools to compile from Slice into target languages, such as C++ and Java, or to automatically generate documentation from Slice files.
Ice The Ice core library. Among many other features, the Ice core library manages all the communication tasks using a highly efficient protocol (including protocol compression and support for both TCP and UDP), provides a flexible thread pool for multi-threaded servers, and additional functionality that supports extreme scalability with potentially millions of Ice objects.
IceUtil A collection of utility functions, such as Unicode handling and thread programming. (C++ only.)
IceBox An application server specifically for Ice applications. IceBox can easily run and administer Ice services that are dynamically loaded as a DLL, shared library, or Java class.
IcePack A sophisticated server activation and deployment tool. With IcePack, the complex task of deploying applications in a heterogeneous computer network is dramatically simplified. Simply write a deployment descriptor in industry-standard XML, and IcePack handles the rest.
Freeze Freeze provides automatic persistence for Ice servants. With just a few lines of code, an application can incorporate a highly-scalable evictor that efficiently manages persistent objects.
FreezeScript It is common for persistent data types to change, especially in large software projects. In order to minimize the impact of these changes, FreezeScript provides inspection and migration tools for Freeze databases. The tools support an XML-based scripting capability that is both powerful and easy to use.
IceSSL A dynamic SSL transport plug-in for the Ice core. It provides authentication, encryption, and message integrity, using the industry-standard SSL protocol.
Glacier One of the most difficult challenges for object middleware systems is security and firewalls. Glacier, the firewall solution for Ice, greatly simplifies the deployment of secure applications. Glacier authenticates and filters client requests and allows callbacks to the client in a secure fashion. In combination with IceSSL, Glacier provides a powerful security solution that is both non-intrusive and easy to configure.
IceStorm A messaging service with support for federation. In contrast to most other messaging or event services, IceStorm supports typed events, meaning that broadcasting a message over a federation is as easy as invoking a method on an interface.
IcePatch A patching service for software distributions. Keeping software up-to-date is often a tedious task. IcePatch automates updating of individual files as well as complete directory hierarchies. Only files that have changed are downloaded to the client machine, using efficient compression algorithms.
Enhancements:
- Various additions, including redundant IceGrid registries.

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.

The RealizationEngine is designed from the ground up to facilitate group communication and collaboration.
It will store that communication to built and manage an institutional knowledge base. It is accessible from any Web browser or Web-enabled device.
Classified information is easily restricted to authorized individuals. Information can be compartmentalized, restricted, or published openly, as appropriate, all from the same system.
Ideas are coherently threaded, and every message is searchable in a single location and in the context of the messages related to it.
Main features:
- Communication base (completely replace e-mail or even Lotus Notes)
- Collaboration
- Idea Management
- Project Management
- Intranet
- Extranet
- Virtual meetings
- Online communities
- Virtual companies
- One or all of the above in a single installation

Liquid Bytes Adaptive Website Framework (AWF) is aimed at software developers and webmasters. Adaptive Website Framework helps you to create dynamical personalized Web sites with community functions, database powered content management, and an administration interface.

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
