NAME

       varnetload - tool to create reproducable network traffic

SYNOPSIS

       varnetload [-d delay] [-t time to run] [-u url]

DESCRIPTION

       varnetload is a simple python script to create reproducable sustained network traffic.

       In  order to use it effectively, you need to have an HTTP server present in your local LAN where you can put files. Upload a large HTML (or
       any other kind of file) to the HTTP server. Use the -u option of the script to point to that URL. Play with the delay option  to  vary  the
       load put on your network.

       delay  Sets  delay between individual downloads in miliseconds. Default value is 1000. But you my find values range from 0 to 500 more use-
	      ful.

       time to run
	      Sets total run time in seconds. Default value is 60.

       url    Sets downloaded resource. Default is http://myhost.mydomain/index.html.

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.
