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

NAME

       tttview - Tele Traffic Tapper viewer- a viewer program for remote, real-time, graphical traffic-monitoring.

SYNTAX

       tttview [-addr recv_addr] [-mcastifaddr addr] [-multicast] [-port recv_port] [-probe addr] [-yscale (K|M|n)]

DESCRIPTION

       tttview is the viewer program in the ttt program suite. tttview displays traffic-data collected on a remote host by tttprobe.

       To run tttview, it is not necessary to be "root".

       The  ttt program suite is yet another descendant of tcpdump but it is capable of real-time, graphical, local and remote traffic-monitoring.
       It won't replace tcpdump, rather, it helps you find out what to look into with tcpdump.

OPTIONS

       -addr recv_addr
	      Specifies the local address. Only useful for multicast addresses. If omitted, "224.8.8.0 is used as default.

       -mcastifaddr addr
	      Specifies the multicast interface address. Only useful when an interface is selected to join a multicast group.

       -multicast
	      Shorthand for the default multicast destination "224.8.8.0".

       -port recv_port
	      Specifies the udp port number to receive traffic-data from a remote tttprobe. If omitted, port 7288 is used as default.

       -probe addr
	      Specifies the address of a probe. Only useful to select one among multiple probes.

       -yscale ('K'|'M'|n)
	      change the scale of y-axis. 'K' and 'M' represent 1000 and 1000000 respectively.

EXAMPLES

       Remark: "hostA" is allways the host where traffic-data is collected with tttprobe and "hostB" is allways the host where the traffic-data is
       displayed with tttview.

       point-to-point monitoring:

	      hostA: tttprobe hostB
	      hostB: tttview

	      or:

	      hostA: tttprobe ip_of_hostB
	      hostB: tttview

       multicast:

	      when using the default multicast address:

	      hostA: tttprobe -multicast
	      hostB: tttview -multicast

	      this is equivalent to:

	      hostA: tttprobe 224.8.8.0
	      hostB: tttview -addr 224.8.8.0
