GNS3 – Graphical Network Simulator
August 26, 2010 by christian · Leave a Comment
GNS3 is a graphical network simulator that allows simulation of complex networks. To allow complete simulations, GNS3 is strongly linked with : Dynamips, the core program that allows Cisco IOS emulation. Dynagen, a text-based front-end for Dynamips. Qemu, a generic and open source machine emulator and virtualizer. GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE. It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers. This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.

GATE: a full-lifecycle open source solution for text processing
August 12, 2010 by christian · Leave a Comment
GATE is over 15 years old and is in active use for all types of computational task involving human language. GATE excels at text analysis of all shapes and sizes. From large corporations to small startups, from €multi-million research consortia to undergraduate projects, their user community is the largest and most diverse of any system of this type, and is spread across all but one of the continents (apparently not in Antartica).
Core GATE is open source free software; users can obtain free support from the user and developer community via GATE.ac.uk or on a commercial basis from their industrial partners. They are the biggest open source language processing project with a development team more than double the size of the largest comparable projects (many of which are integrated with GATE). More than €5 million has been invested in GATE development; their objective is to make sure that this continues to be money well spent for all GATE’s users.
This note summarises the GATE software and process and gives examples of some of their uses. We believe that GATE is the leading system of its type, but as scientists we have to advise you not to take our word for it; that’s why we’ve measured our software in many of the competitive evaluations over the last decade-and-a-half (MUC, TREC, ACE, DUC, …). We invite you to give it a try, to get involved with the GATE community, and to contribute to human language science, engineering and development.
Puppet – Data center automation and configuration management
August 2, 2010 by christian · Leave a Comment
Puppet is an open source data center automation and configuration management framework. Puppet provides system administrators with a simplified platform that allows for consistent, transparent, and flexible systems management. Puppet lets System Administrators spend less time on mundane tasks and instead focus on managing their infrastructure strategically. Puppet’s declarative language describes your system configuration, allowing you to easily reproduce any configuration on any number of additional systems. Additionally, Puppet can help establish and enforce approved system configurations automatically correcting systems that drift from their baseline. Puppet provides an audit trail of all your systems, which can easily be kept in version control for compliance purposes. Whether you have a small, heterogeneous network of user workstations or a cluster of rack-mounted number-crunchers, Puppet can help reduce your overhead and get the everyday management of your network under control so you can concentrate on the real problems.

Monitorix: free, open source, lightweight system monitoring tool
April 6, 2010 by christian · Leave a Comment
Monitorix is a free, open source, lightweight system monitoring tool designed to monitorize as many services as possible. At this time it monitors from the CPU load and temperatures to the users using the system. Network devices activity, network services demand and even the devices’ interrupt activity are also monitored, and more. The current status of any corporate server with Monitorix installed can be accessed via a web browser.
It has been designed to be used under production UNIX/Linux servers, but due its simplicity and small size you may also use it to monitor embedded devices.
All its development was initially created for monitoring Red Hat, Fedora and CentOS Linux systems, so this project was made keeping in mind these distributions. Today it runs on different Linux distributions and even in other UNIX systems like FreeBSD.
Monitorix is an open source project and, just like any other open source project, anyone can contribute with its own time and knowledgements.

The goal of this website is to give an end to end open source solution for a typical small company including Telephony, Document management, Customer Relation Application, Networking, Remote access, Desktop solutions and so on.
Although only the tools/applications have been listed on the website for the moment, a complete network diagram and individual how-to articles will follow.
Please note that for most of the installation instructions, we will not re-invent the wheel. A large number of very competent experts have already written how-to articles, we will just refer you to those. We will only document the missing links between the different components or if we feel that some installations could be better documented.

Please note that the text for each of the blog post is taken from their respective websites. The KinDev team have experimented with those tools at different occasions. Your need and requirements could be different than the ones identified by our team for a specific situation, please take the time to read and understand the tool/application features before starting to install in a production environment.
We hope that you will have as much fun as we have discovering, installing and using those tools/applications and please do not forget to donate to the respective open source volunteers that have changed the IT landscape for ever.
