Real-time network monitoring
GNetWatch is a free open source Java application that offers real-time graphical monitoring and analysis of network performance through SNMP and ICMP. To get an instant view of the network state, data are collected, stored and displayed every few seconds. Two traffic generation modules are available. The former can flood UDP packets of any size (jumbo frames for instance) and tagged with any DiffServ/ToS flag for QoS and class of services testing. The latter can generate a huge quantity of parallel requests to any HTTP(s) server, for web applications load testing. To automatically discover new hosts, GNetWatch can make use of Ethereal/WireShark and later invoke NMap to get informations about the remote systems. Note that IPv6 and SNMPv3 are fully supported by GNetWatch.
March, 9 2016 - VERSION 4.1 RELEASED
This version supports both 32 and 64 bits Linux and Windows operating systems.
Dec, 30 2008 - VERSION 4.0 *BETA* RELEASED
This beta version allows many more SNMP tables to be downloaded (like routing, arp, interfaces and mac tables). Moreover, multiple graphs may now be displayed on the same statistics window.
Note that this is an unstable pre-release version. If you need a production version, download release 3.1
May, 26 2008 - VERSION 3.1 RELEASED
This update lets the user add its own probes by means of generic actions that can spawn external processes or track the content of external files. Some standard generic actions are also provided: remote cpu load and remote free memory (using Windows Management Instrumentation for MS-Windows targets and system tools for Unix/Linux targets). The documentation has been updated with these new features.
The documentation is available in PDF format and in single-page html format. See the Documentation section of the site.
Prior to downloading GNetWatch, carefully read the documentation. It will help you choose the best installation way. Then download GNetWatch: please refer to the Download section of the site.

This is an AVI2PPM (avi to ppm) transcoder running under Windows : it decodes the frames in any avi file and stores each of them into a separate ppm file (Portable PixMap : standart Unix format). Of course, you need to get the decoding codec corresponding to your avi file on the PC where you run avi2ppm.exe. More informations here.
