A simple question I hope.
I want to experiment with point-point encrypted wifi link. Have 2
machines with AR5212, 5213, 5213A+RF2112A or something like that.
iwlist enc / iwlist keys says:
wlan0 2 key sizes : 40, 104bits
4 keys available :
[1]: off
[2]: off
[3]: off
[4]: off
Current Transmit Key: [1]
iwlist auth:
wlan0 Authentication capabilities :
WPA
WPA2
CIPHER-TKIP
CIPHER-CCMP
Current Authentication algorithm :
open
shared-key
iwlist wpakeys:
wlan0 2 key sizes : 40, 104bits
4 keys available :
Error reading wpa keys (SIOCGIWENCODEEXT): Operation not supported
Now, is it possible to use, for example, CCMP cipher with 256-bit key?
How do I set the key and CCMP mode?
Or, how do I set 104-bit and WPA+TKIP?
IOW, how do I set it up?
I noticed "iwconfig wlan0 key XXXXX" (104 bits) make the transmitting
card encrypt data, but the receiving card doesn't seem to decrypt them
(tcpdump shows encrypted traffic on receiving wlan0 and nothing
works).
Perhaps there is some faq or example?

You use wpa_supplicant with an ad-hoc WPA config (ie,
key_mgmt=WPA-NONE). I don't think iwconfig has the ability to set TKIP
& CCMP keys, thought it might have grown that ability when I wasn't
looking.
