That's what I recall from Windows and I allow 0, 5 or 13 characters as 0 -> erase key 0xDDDDDDDDDD -> set 40 bit 0xDDDDDDDDDDDDDDDDDDDDDDDDDD -> set 128 bit I also verified it did the right thing by booting back into Windows and then running the WEP utility to see if it made the right change. Also did it as hex since that is what the WEP utility did. The code would probably work with ASCII strings but how do you encode 0-255 as a character in an ASCII string? BTW my test string was 0x001122334455 (for 40 bit). Originally I wasn't doing a 40 bit or 128 and things didn't work. Once I started doing 40 bit or 128 bit keys then things worked fine. Since the programming doc didn't say anything about that I burned a few days on that :-( | > I didn't provide patches to ancontrol as you did, but I find ancontrol | > is getting way too nasty with its switches.

I'm | looking forward to some sort of working crypto support for the aironet | cards. Well if you just download mine for now again at www.ambrisko.com/doug/an.patch.wep That will get you going. Some people other then myself are using it with success. It looks like it will get some more features since it looks like he has gleaned some more knowledge then I was told. Give it a try and let me know if you run into a problem. Doug A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
