Not really. Recording traffice is exactly what it does, any an all traffic that makes it as far as the interfaces. However it is not a good tool for most people for examining the data, ethereal (among others) might be a tool that could be used for that. You can examine the snoop recordings using etherreal.

Ok, I'm too used to c/java. I want to go through a file to search for lines matching a given string using:
fgrep "matchString" anyfile.dat;
This works like it should, but I would like to record the lines in an array, rather than echo them. Any ideas? :eek:
Thanks.

guessnet-scan
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.
