Free distributed network software for linux

Distributed Network John The Ripper is a client/server framework that wraps around a slightly modified version of John The Ripper.
In contrast to the MPI version of John, dnetj allows the use of nodes which are of differing speeds and for nodes which do not run 24/7.
This tool was written for a number of reasons, firstly the MPI version requires an MPI installation on each node, and for the nodes to be configured together and be roughly the same speed. Also, although other distributed password crackers exist (such as djohn or medussa) they all have their own limitations.
The server loads a set of password hashes, and splits the available keyspace into "work units" of a configurable size. The clients connect and retrieve the hashes, as well as a set of work units to process. Once a client has processed some work units, it connects back to the server to submit the completed units as well as any passwords which have been cracked.
Possible uses include eg, running as a background task on all the workstations in an office.
Note, this tool is at an early stage of development and is likely to be very buggy, although it is functional. Bug reports and/or patches are strongly encouraged.
Main features:
- Distributed client/server model, any number of clients can be supported and can be brought up and down at will
- Support for any cipher supported by John 1.7.2 (additional cipher patches should be able to be applied normally)
- Keep the changes to John to a minimum, so that patches/updates can still be applied without too much fuss
- Uses the same optimized encryption routines as John
- Cracked hashes are stored in the standard john.pot format, so they can be displayed with john -show
- Passwd files sent to clients are sanitised (only the hash is sent, other fields from the passwd file are removed)
- Capability for auto client registration
- Code is intentionally kept clean to aid porting
Supported Platforms
Dnetj has been tested on the following systems:
- Linux/x86
- Linux/amd64
- Linux/sparc
- MacOSX/PPC
- MacOSX/Intel
- Solaris/x86
Version restrictions:
- Clients will sometimes crash if unable to connect to the server for a long period of time.
- Work unit size is limited to a 32bit integer number of crypts (ie: 4294967296)
- Node performance calculations wrap once the node has performed more than 4294967296 crypts, so nodes may appear to be much slower than they truly are.
- Doesnt work with NTLM, as the NTLM hash is stored in a different field of the passwd file.
- Traffic is sent in plain text (this makes debugging easier at this early stage of development)
- Makefile is very basic, and has no configure script, compilation on Solaris requires adding -lnsl -lsocket to the compile command.
Enhancements:
- Basic functionality is implemented, and dnetj is usable, but there are many things still to be implemented and a lot more testing is needed.

Distributed BEAGLE provides a distributed evolutionary computation system.
Distributed BEAGLE is a master-slave distribution extension of the evolutionary computation framework, Open BEAGLE. Its key features are robustness, fault tolerance, adaptability for heterogeneous networks, and transparency for the user.
Main features:
- Based on the generic framework Open BEAGLE
- Minimal changes required to modify an Open BEAGLE application for distribution
- Ten GA and GP examples converted from Open BEAGLE
- Communication based on TCP sockets using XML encoding
- Data persistency insured on the server by a SQL Database (SQLite)
- Load balancing of computational tasks for uses on heterogeneous LAN
- Open source (LGPL license)
- OS-calls wrapped into generic C++ classes
- Compiles on UNIX (Linux/OS X) with gcc 3.x and Windows with Visual Studio .NET
Enhancements:
- Bug fixe: variable deme size could crash the server (Thanks CG).
- Suggestion: Compression of connections can now be activated by clients if the option is set to "-1".

Distributed Internet Backup System works by doing all its communication through email. The benefit of using email for transport is that clients behind firewalls or with intermittent connections to the Internet can use DIBS reliably.
Since disk drives are cheap, backup should be cheap too. Of course it does not help to mirror your data by adding more disks to your own computer because a virus, fire, flood, robbery, power surge, etc. could still wipe out your local data center.
Instead, you should give your files to peers (and in return store their files) so that if a catastrophe strikes your area, you can recover data from surviving peers. The Distributed Internet Backup System (DIBS) is designed to implement this vision.
Note that DIBS is a backup system not a file sharing system like Napster, Gnutella, Kazaa, etc. In fact, DIBS encrypts all data transmissions so that the peers you trade files with can not access your data.
Enhancements:
- Added Peer Finder service to allow advertising and automated exchange of peering information. See manual for details.
- Updated add_peer and edit_peer commands to allow sizes to be specified using k, m, g, t (e.g., 10k, 10m, 10g, 10t).
- Updated the protocol DIBS uses to exchange store, unstore, probe, and other messages between peers. The new protocol is XML based to allow easier debugging, parsing, and extensions.
- Fixed a deadlock bug reported by Jason Martin in a message to the dibs-discussion mailing list.
- Made the daemon run its periodic checks like spawnning auto_check, process_message, etc., as soon as it starts up.
- Other minor bug fixes and improvements

Distributed Access Control System is a complete, light-weight, single sign-on and role-based access control system distributed under an open source license. It provides:
- extended authentication and role-based access control capabilities for Apache-based web services, CGI programs, and virtually any program or script;
- a wide array of flexible, modular, and efficient authentication methods, including two-factor authentication and hardware tokens;
- powerful, rule-based authorization checking that can be applied transparently to any resource or activity (such as web services, web content, and program features) by Apache-based web services and CGI programs, or virtually any program or script;
- an Apache 2.0/2.2 module, suite of CGI programs, and collection of command line tools for Unix-type platforms, such as Linux, FreeBSD, and Solaris.
Enhancements:
- This release includes an important bugfix to local_passwd_authenticate that prevents invalid passwords from being accepted.
- Some minor bugs have also been addressed, including some problems with dacs.quick(7).

Distributed Multiplatform Framework is a component-based programming framework using XML (or currently a hardcoded variant) as the repository.
The samples are implemented either in console or wxWidgets. This shows the independence of the GUI or UI.
This framework includes a database form sample that let you modify content of ODBC SQL data sources.
Distributed Multiplatform Framework project shows how simple it is to create database driven applications.
With version 0.6.0 the features are nearly complete. It could show simple database forms, master-detail database forms and would also capable to show it in tabbed, dialog based or combined layouts.
Whats New in 0.7.1 Stable Release:
- The ODBC code has been fixed to work properly with MS SQL databases.
- Missing vendor libraries have been added that broke the build system.
Whats New in 1.0 RC1 Development Release:
- The most important new feature is the ability to import UML designs.
- To make a database application prototype, you now only need to design some classes with attributes and build relations using an aggregate from one class to another.

SPyDI Is a powerful engine to create distributed full text indexing systems and distributed search engines.
Simple Python Distributed Indexing library supports harvesting, crawling (pull mehtods), and push methods (via a Web interface or SPyRO Web services).
It supports boolean and vector Information retrieval models. It has few dependencies, and comes with its own HTTP server and HTML embedded pages language (called pyew and wey pages), and session manager.
It can use the SMTP of the Python library. It supports replacing the default modules with some better modules (Apache, exim, etc).
Enhancements:
- Monarca updates to support SPyROs new HTTP protocol management.
- Some bugfixes in pyew pages.
- General code cleanup.

Pinger Network Tools is a simple frontend for ping, netstat, traceroute and whois.

My first ever Kommander script that I did in an effort to learn the Kommander scripting engine/style and to have something useful.

Built with Kommander Editor 1.2

Distributed Aide Runtime Controller is a multi-threaded Python application designed for managing AIDE installations in large heterogeneous networks.
AIDE is an open-source improvement upon the academic release of Tripwire. It can be used to detect filesystem changes in unix environments, which is useful for forensics on compromised systems and tracing illicit system configuration changes.
Darc provides a mechanism to run AIDE integrity checks across many unix systems from a single management station. It has the following features not available in a traditional AIDE installation:
- Maintaining read-only media databases on each system - not a trivial task! - is not required for day to day operations.
- Unified reporting - the admin doesnt have to read individual reports for each system.
- Integrated syslog support to notify admins when a system may have been compromised.
- Databases and configs are never written to the filesystems on the monitored hosts.
Enhancements:
- Better error handling and reporting
- HTML reports for easier navigation within the report
- Configurable timeout values for all relevant metrics - TCP connection timeouts, SFTP transfer time, AIDE run time
- Built-in support for aide database maintenance tasks (init, update) so the manual file manipulation required in 0.2 is completely eliminated.
