I'm having difficulty (as others are) setting up a wireless network adapter under KNOPPIX. I am getting close: I can get Airsnort to recognize the adapter but only if I log in as root.

I'm using a D-Link DWL-122 wireless adapter. I've not tried rebuilding the kernel nor downloading new drivers: KNOPPIX V3.4 apparently has the Prism2 driver already available

My sequence of events is as follows:

First I boot up w/o the adapter in place. I log in as root by using su
Next based upon some postings from others I remove the Prism2 module

root@ttyp0[knoppix]# modprobe prism2_usb -r

I install the DWL-122 Wireless Network adapter into the usb port and still as root I re-install the Prism2 module and run the following commands:

root@ttyp0[knoppix]# modprobe prism2_usb prism2_doreset=1
root@ttyp0[knoppix]# wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
message=lnxreq_ifstate
ifstate=enable
resultcode=success
root@ttyp0[knoppix]# wlanctl-ng wlan0 lnxreq_autojoin ssid=MySSID authtype=opensystem
message=lnxreq_autojoin
ssid='MySSID'
authtype=opensystem
resultcode=success

(where MySSID) is the identification I've given my home network)

root@ttyp0[knoppix]# ifconfig wlan0

The system thinks I'm all set, at least as the root operator. I go into AirSnort from the console as root operator and it comes up, finds the card, and starts logging packets.

If I log out of root and am running as knoppix and enter AirSnort the the system will not go into the monitor mode: apparently it does not recognize Wlan0 anymore.

Anyone have any hints/ideas where I go from here?
thanks
