Introduction to Analysis Worksheet

[James Garringer]

Hello All,
This is a simple worksheet that was designed to give Wi-Fi Engineers new to protocol analysis an opportunity to create filters for use with Wireshark.

Hope this helps someone.

That rocks, thanks James!

Here’s another cool Apple tidbit:

Apple Channel Utility Test


Client induced channel saturation


Within a terminal window:

To generate traffic on a WiFi interface, pick an available IP on the network.

Set a static arp entry for a fake host on the same network. You may be required to use sudo for the arp command.

arp -s 10.0.1.199 ab:cd:22:22:22:22

! mac is arbitrary
! IP should be on same segment

Send a bunch of traffic out the interface

cat /dev/random | nc -u 10.0.1.199 22

! include port # after ip address

Control-C to quit

Very nice, James! I especially like the blank cheat-sheet that you fill out as you make discoveries. The self-paced exercises are well thought out for beginners. Exercises 5 & 6 are the basis for determining the level of collisions occurring on the WLAN, and could be filtered further to show the amount of collisions per channel or device.
