WPC11 v4 - SSID broadcast - hiddenAP=true


Hey Group

Has anyone had any success in turning SSID broadcast OFF at the accesspoint
(also known as closed wireless)
an then connect the WPC11v4 to it ??

i believe the "hiddenAP=true" is for that, but i can't get it going
when i turn ssid broadcasting at the AP on, it works
(only under rh9 after reading the entire thread earlier)
i also had the luck to get wep working sharedkeys and all
if i have a bad day and bootup in windows, i can use the wireless
in "closed wireless" mode, but only if I put my SSID name in manually duh...
-+-+-+-
/sbin/insmod rtl8180_24x.o
#/sbin/insmod priv_part.o
/sbin/iwpriv wlan0 wlan_para networktype=infra
/sbin/iwpriv wlan0 wlan_para channel=6
/sbin/iwpriv wlan0 wlan_para hiddenAP=true
/sbin/iwpriv wlan0 wlan_para ssid=wlan
/sbin/iwpriv wlan0 wlan_para ssid2scan=wlan
/sbin/iwpriv wlan0 wlan_para authtype=sharedkey
/sbin/iwpriv wlan0 wlan_para wepmode=wep104
/sbin/iwpriv wlan0 wlan_para wepdkeyid=0
/sbin/iwpriv wlan0 wlan_para wepkey104_1=something
/sbin/iwpriv wlan0 wlan_para wepkey104_2=something
/sbin/iwpriv wlan0 wlan_para wepkey104_3=something
/sbin/iwpriv wlan0 wlan_para wepkey104_4=something
/sbin/iwpriv wlan0 enable
and so on..

This SSID broadcast is a very important security feature
you can crack this wep, but only if you can find it !!!
so i hope to here of some one successful in this

best regards
Lasse

Congratulations on getting the v4 to work, and with WEP. I have to take issue with your position on SSID, though.

Hiding the SSID broadcast is a horrible security feature, in part because of the assumption that it works. The SSID will be broadcast in response to probe requests even with broadcast "disabled". That behavior is part of the WiFi protocol, so the term itself is a misnomer - a "me too" marketing bullet.

APs that are not beaconing may not show up on NetStumbler's radar, but will be immediately seen by Kismet or Airsnort. Someone equipped with the latter two tools is more of a concern to me than one with the former.

Cracking WEP is more difficult than many would have you believe, but relying on SSID broadcast disable is dangerous. Security through obscurity isn't. Use 802.1x with a secure authentication method such as EAP-TLS, TTLS or PEAP.

To use any 802.1x authorization method, you need:
An authenticator - an access point that supports 802.1x
An authentication server - FreeRADIUS, Meetinghouse or Funk RADIUS or Windows IAS
A supplicant - Xsupplicant, Meetinghouse AEGIS or XP 802.1x.

One link to the basics: http://www.mtghouse.com/MDC_8021X_White_Paper.pdf

You can do it with all Linux, all Windows or some combination thereof. A decent thread on PEAP: http://www.dslreports.com/forum/rema...6052~mode=flat

Make sure you use a CVS snapshot of FreeRadius. PEAP isn't supported in the 0.9.3 release.
