Step 2. Setup configuration

Without proper configuration kismet will not be able to run.

taufanlubis@toshiba:~$ sudo gedit /etc/kismet/kismet.conf

……

…… (just change these 2 lines)

suiduser=taufanlubis

source=ipw3945,eth1,addme (your capture source)

……

……

suideuser is your user id

ipw3945 is your wireless card chipset modul.

How to know that ipw3945 is the right module?

You can check using command ‘lspci

03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

Now, I know that my chipset is Intel Wireless 3945.

Then, how could I know which module that I should use?

The list is available at www.kismetwireless.net/documentation.shmtl

Sample of Capture Source:

Source type: ipw2100 Intel/Centrino Linux ipw2100-0.44+ http://ipw2100.sourceforge.net/ The Linux IPW2100/Centrino drivers for 802.11b cards now support rfmon, so here's support for them.  They act more or less like any other wireless interface would.  Source type: ipw2200 Intel/Centrino Linux ipw2200-1.0.4+ http://ipw2200.sourceforge.net/ The Linux IPW2200/Centrino drivers for 802.11bg cards support rfmon as of 1.0.4 and firmware 2.3.Signal level reporting requires radiotap be turned onin the makefile while compiling the driver.  Noise levels are not reported.  Source type: ipw2915          Intel/Centrino Linux ipw2200-1.0.4+ http://ipw2200.sourceforge.net/ The Linux IPW2200/Centrino drivers for 802.11bga cardssupport rfmon as of 1.0.4 and firmware 2.3.This is the same as ipw2200 but defaults to scanning the 802.11a channel range in addition to 802.11b/g.Signal level reporting requires radiotap be turned on in the makefile while compiling the driver.  Noise levels are not reported.  Source type: ipw3945          Intel/Centrino Linux ipw3945 http://ipw3945.sourceforge.net/ The Linux IPW3945/Centrino drivers for Intel Core 802.11bga cards.

As you see, Chipset Intel 3945 a/b/g uses ‘ipw3945′ source.

pktstat listens to the network, shows and summary the bandwidth being consumed by packets of various kinds on an interface in real time. Each line displays the data rate associated with different classes of packets.

It understands some protocols (including FTP,HTTP, and X11) and adds a descriptive name next to the entry (e.g., ‘RETR cd8.iso’, ‘GET http://slashdot.org/’ or ‘xclock -fg blue’).

(taken from http://www.ntop.org)

Ntop is a network traffic monitor that shows the network usage. It display a list of hosts that are currently using the network and reports information concerning the (IP and non-IP) traffic generated and received by each host. It is similar to what the popular top Unix command does.

Ntop may operate as a front-end collector (sFlow and / or netFlow plugins) or as a stand alone collector/display program. A web browser is needed to access the information captured by the ntop program. The ntop users can navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. It looks like an agent with an embedded web interface.

Ntop needs a limited configuration and administration via the web interface, reduced CPU and memory usage. It’s easy to use and suitable for monitoring various kind of networks.

What ntop can do for me?

  • Sort network traffic according to many protocols

  • Show network traffic sorted according to various criteria

  • Display traffic statistics

  • Store on disk persistent traffic statistics in RRD format

  • Identify the identity (e.g. email address) of computer users

  • Passively (I.e. without sending probe packets) identify the host OS

  • Show IP traffic distribution among the various protocols

  • Analyse IP traffic and sort it according to the source /destination

  • Display IP Traffic Subnet matrix (who’s talking to who?)

  • Report IP protocol usage sorted by protocol type

  • Act as a NetFlow / sFlow collector for flows generated by routers

  • Produce RMON – like network traffic statistics

It has been developed by Luca Deri, and Italian research scientist and network manager at University of Pisa.

Show web traffic

taufanlubis@toshiba:~$ sudo tcptrack -i eth0 port 80

Only show connection from IP address 10.66.29.121.

taufanlubis@toshiba:~$ tcptrack -i eth0 src or dst 10.66.29.121

You can see the source (client) and destination (server) addresses and ports, connection state, idle time, and band witch usage.
