count your IVs (airodump/aircrack)

macromicro · 11-06-2004

this is a very bash basic script that i came up with when i started getting too many .cap files and couldn't remember for which SSIDs i had the most IVs.. i'm using it with cygwin for windows but there's nothing in there that shouldn't work with a full linux system. i can add more to the script to extract other kinds of information from the .csv files, if anyone shows any interest. feel free to add whatever.. cheers, kpm

begin:

# countiv is a little hack that counts the number of IVs
# that are captured for a particular WEP-encrypted wireless network.
# Run the script in the directory that has your airodump
# .csv files. The string that you enter to search for
# should be the name of SSID of the wireless hub you're
# trying to crack, or a segment of the SSID that is unique
# to that hub.
#!/usr/bin/bash
echo 'enter a string to search on (case sensitive): '
read string
iv=0
for var in `grep $string *.csv | cut -d',' -f9`
do
iv=`expr $iv + $var`
done
echo "There are $iv IVs for $string"

I know absolutly nothing about programing. But how about just tallying the number if iv's for each ssid in the cap file? Then you wouldn't even have to guess each ssid separately to see how many iv's you have for it.
