[SLUG] Listing local wifi access points?

[Erik de Castro Lopo]

Hi all,

Does anyone know tool to list all local wifi access points with their
channel numbers and encryption types? Preferably command line (but I'm
running Gnome with network manager on a Debian system if there is
something that fits in with that).

Cheers,
Erik

Execpt that it doesn't seem to support my wifi hardware.

The aircrack-ng  suit contains a utility that
will list AP's.  It never ceases to amaze me how many open networks there
still are out there, that and loads of people still use WEP.

Sorry, any program whose getting started tutorial [0] has a first
step of "Determine the chipset in your wireless card" is going in
the wrong direction.

I have absolutely no interest in cracking other peoples wifi. What
I'd like to do if figure out which channel in my local area is the
least congested so I can park my AP on that channel.

Who said anything about 'cracking' other people's wifi? Airodump-ng is an
audit utility and is similar to kismet, it will tell you all the AP's in the
area including the channel that they are on.  The best way to determine if
it works is simply to try it, I did not bother about working out the
chipset.  You'll find that most of them work with either kismet or
airodump-ng.

* get a windows box with a wireless card
* grab inssider
* run inssider
* done/done.

If you have an Android phone then there is a great app that does everything you 
have asked for plus some more.
http://www.android.com/market/#app=com.farproc.wifi.analyzer

It even has a mode that will suggest the best channel for you.

... Yes that works. However, imho the windows part is a real turn off ;)

Cool.  Don't forget that if you are using 2.4GHz there are *three* channels,
no matter what the card says: only 1, 6, and 11 are non-overlapping, so you
will get a performance hit from anything that crosses over between them.

Only if don't already have it installed. :)

.. but having to pick the right monitor mode for the right card just to get
it to work was an absolute pain.

I finally managed to get it working on my netbook w/ an atheros chipset; but
it was fiddly. And I'm -hacking- on the wireless code at the moment. :)
(I then just rebooted back into XP mode to run inssider, as all I wanted was
RSSIs.)

That said, Kismet is great if you want to do detailed wireless debugging. :)
It just isn't easy. :)

That (all) said, it wouldn't be hard to write a *NIX Inssider clone; it
"just" uses the card-reported RSSI from channel scans. Kismet does a lot more
and thus wants monitor/intercept/debugging modes (which is why it's fiddly.)
