GNetWatch 3.0 (Default branch)
Image GNetWatch is an 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 application load testing. To automatically discover new hosts, GNetWatch can make use of Ethereal/WireShark and later invoke NMap to get information about the remote systems. Note that IPv6 and SNMPv3 are fully supported by GNetWatch. License: GNU General Public License (GPL) Changes:
This release comes with a complete rewrite of the internal data engine, now based on an Object-Relational mapping performed using hibernate. Configuration parameters, targets, and collected data are now persistent and stored in an SQL database. Users can thus browse previously collected data by dragging the mouse in the chart windows. For easy deployment, MS Windows and Linux bundles are shipped preconfigured with an embedded SQL engine: there is no need to configure any external database.Image

GUESSNET-SCAN(8)					      System Manager's Manual						  GUESSNET-SCAN(8)

NAME

       guessnet-scan - guess network configuration data by looking at network traffic

SYNOPSIS

       guessnet-scan [options] [ethernet_interface]

DESCRIPTION

       Guessnet-scan tries to deduce network configuration data by watching network traffic at a given Ethernet interface.

       After  scanning	network  traffic  for some time, guessnet-scan prints a configuration string suitable for inclusion in /etc/network/inter-
       faces.

       Note that guessnet-scan uses heuristics and wild guesses and that the resulting data is not guaranteed to  be  accurate.   The  program	is
       intended to be used as a first try at getting network configuration data without bothering anyone.

OPTIONS

       Options follow the usual GNU conventions,

       --debug
	      Print debugging messages.

       --help Show a brief summary of commandline options.

       --init-time=int
	      Time in seconds to wait for the interface to initialize when it is not found already up at program startup.  Default: 3 seconds.

       -t, --timeout=int
	      Time in seconds to watch for network traffic.  Default: 5 seconds.

       -v, --verbose
	      Operate verbosely.

       --version
	      Show the version number of the program.

SCANNING REQUIREMENTS

       To  correctly  identify all data of the local network, guessnet-scan needs to see traffic related to a host in the local network and to the
       local gateway, if any.

       To be able to identify the network gateway, guessnet-scan also needs to see some traffic directed to the external network: you can help the
       detection  by  generating  some	outbound IP traffic during the scan, for example by browsing a web page (without proxy) or using telnet to
       open a connection to some remote host.

       Note that if you are connected to a switch, guessnet-scan won't probably be able to work, since the switch will isolate it from the network
       traffic that the other machines are generating.
