Description
------------------------------------------------------------------------
 wltracker.pl is used to enumerate wireless 802.11 lans.

 With wltracker.pl running together with a 802.11 pcmcia card and Windows
 2000 you can have the computer silently running packed in your computerbag
 while going downtown and the script will log all open networks encountered

------------------------------------------------------------------------
Syntax:
------------------------------------------------------------------------


Syntax: wltracker.pl -i <sleep interval in seconds>

Mandatory switches:
-------------------
 -i <sleep interval in seconds>

Example: -i 5
This would make wltracker.pl sleep for 5 seconds between each lan check

 Change History
 ------------------------------------------------------------------------
 Version 1.0:
 Fieldtesting showed that the script indeed filtered out 0.0.0.0
 addresses.
 I disabled the built-in NIC in my computer before running the script
 and you should do the same for now.
 Some day I will optimise this script for working with
 2 NICS but not today, pal.

 It seems that there is a slight delay between the time when
 a DHCP address is assigned *and* a default gateway is assigned.
 God knows why, and I am not in the mood to find out.
 A slight delay between the time when a new net is discovered and when
 the logging occurs should fix this!

 Version 0.9:
 To get this to work quickly I use the ipconfig utilty to get this to
 work. I know that I can get this by using the WIN32 API module and a
 Windows DLL, but that will be implemented later on, dude!

 ------------------------------------------------------------------------
 Known Issues
 ------------------------------------------------------------------------
 There are some issues regarding having several NICS in the same computer
 Please see the Change History for details!

 All nasty letters will be sent to /dev/null and if I can track you down
 I may come over with my bouncer friends and a baseball bat. You have been
 warned... :-)
