Yeah, no, +WEP should work. I haven't specifically tested it but I see no reason for it not to work. > Any particular reason IBSS would require a userspace MLME?

Well, I was really thinking of RSN/WPA, and last I checked wpa_supplicant didn't even support that with IBSS, and I think it requires userspace MLME because you have to do the auth/assoc sequence with each peer etc. johannes --=-daCnBkfDuXGIpD8KzaJP Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJIVtEVAAoJEKVg1VMiehFYrvcP/jXfUPUlaqEeYdjTM9g9KMJH SDHckkfKnxqIfMWhhi8A2Wuu2IW95RCTeG3IkW4l0PRcQYCd7kz/jQMjUZgAqZBx M6mJrEDtdUN7Um0nEM3VgYlP6wguytCGVBUVJDxrpMRbQt+lRriDBGXrHxm/QpUj GJJ5ykS1nhbICxWexLUmcinni7wJ35pbrZnw5LGb2pOh4fwm+uuH0b9zE/eoDpBB OJTi8IPLAM052seunFegMIVwlZwJFyFbbqd/HEWx3cGWS0avjrOZu4T+iENKhIJo Ty6FhHn5L7eValphXhbWevi3UBUuhdrTvR9qYjj96Rr9piAg5fOqOcrJz0Plug/+ 1iumLju3QCv7HdGnMskM6Yv54mTd4hiaITh72X3/UOq65DxXZTGfw0E4aj+kI+Ml KLXpwBs5mg2PHzaqY0BnnraNNwBjRX5MyitryJWI36U7vFckz9c7QZw64IGuFGOo qDYxVwdqJwKIedxbPmHvOmB3iNgGGkkhW6YD4zuQHtjM4MmAeyHmS+UVIrEE5KJ5 +60HFLjBNqHHHCjSuuGG90n7pg/f40eLxZ1mngN/RjWkkkqTzh3cZFQh8v/E11Xl QqdIKDUaj2WPCaITwyS72L+V9VeaTLpS+fahnG/ubbA9no4G8q72PJ7Hlq6bMsZJ DttZQboXCc24p1E3xbPK =Fsx0 -----END PGP SIGNATURE----- --=-daCnBkfDuXGIpD8KzaJP--
