JRF is a client/server application that allows to extend local storage to other computers running the JRF Server. It has been designed for ultra-simplicity, **not for security!** It does not request for authentication when accessing files on a remote server, nor does it prevent access to files or directories. It has been designed for already-secured networks (e.g. LANs or inside VPNs), where file-sharing setup is tedious (or impossible). Basic access configuration/restriction should be performed on the OS, by changing rights of the user running the JRF Server. It is like an insecure FTP-like file sharing runnning on a single TCP port. Its Java nature gives Java programmers access to remote files as remote `InputStream` and `OutputStream`, with the added value of optionally **compressing data exchange** to ease up network usage.

JRadius - A Radius Server Java Adapter and Java Client

A simple Network monitoring tool for viewing the status of multiple nodes. It uses a simple text configuration file to get a list of IP addresses or host names to ping at an interval.

OpenQueue is an open protocol for publish-and-subscribe message queuing. This enables language-independent, loosely-coupled, asynchronous communications between applications on platforms supporting TCP. Similar to MQSeries or MSMQ, but open.

winKnocks is an encrypted(DES) port knocking tool. Knock sequences are defined through XML files; users specify: number of packets of each knock sequence, payload and header of each packet. Logging capability. Generation of smoke packets.No replay-attack

A java-based 3D Visualisation tool for analysing network traffic. Written with jMonkeyEngine.

Vitamin is a software for visualizing network traffic in IP based networks. It works as a distributed system. Several slaves capture the network traffic on several computers in a network. The master visualizes the information he receives from the slaves.

This tool check every x seconds your public ip adress, if it changes (vpn fall down for example) it stops one or several programs. When the VPN crash this tool can send a mail, play a sound. - This tool work on Windows and Linux. - You need to install JAVA 1,8 on your operating system - Download checkvpn.zip and unzip it - Double click on checkvpn.jar - Click on the button « Update ip » when the VPN is stopped to get your public ip address. - Type the programs separated by semicolon that you would like to stop when the vpn is falling down (ex: utorrent.exe;firefox.exe on linux just put « firefox » no extension) - Click on start button and the program will check every x seconds your ip address, if it not the vpn's ip the programs will be stopped by this tool. - The option « auto start » start the process automaticaly. - The ip adress is geolocalized via MaxMind the web site http://check.vpn.free.fr

WSNWARE is an open source Java/OSGi middleware, designed for monitoring, controlling and standardizing Wireless Sensor Network. WSNWARE is a normalized message oriented middleware running on (and developed for) any OSGi containers.

The Amenetet Monitoring Service monitors remote services which register with it, heart beats are used in both directions to monitor the health of remote services. Remote services maintain a lease with Amentet and renew that lease regularly. Amentet then pings back to the remote service to monitor its health. Remote Services can monitor multiple objects internally, when "pinged" by Amentet, if any of these objects has disappeared an exception is thrown back with the list of missing objects. Amentet will store events in a local Db which can be viewed using the Web interface and as events occur alerts will be raised which can be sent to SNMP Trap daemon and/or SMTP and/or SMS. The service uses Spring Security Framework for access control and can be configured to use any Authentication Authorization system supported by the Spring Security Framework.

DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

Gives you the ability to share & manage files from your windows pc on another device(MAC,LINUX,ANDROID etc) in the same network without needing another application on the receiving(client) end, (the client uses the devices browser to download, or view/modify files). It contains an inbuilt http server hence no need for an application on the receivers end. The host turns on the application and the client opens the browser and types the ip address including the port ( the application automatically generates it, hence no need for ipconifg on cmd or any other ways to get ip), then he has access to all the files on the other pc with a very beautiful interface. the client also has a possibility of watching videos, playing music and images directly on his or her browser without having to download it. Depending on whether there is read write access, the client can move files to other directory, delete multiple files, download multiple files to his/her own device and many other options
