Re: [Bluez-devel] Problem to connect hci as non-root

[Frederic Danis <frederic.danis@palmsource.com>]

I agree with you that Linux should not need a pairing/bonding 
application. But we got one and want to keep it when porting our 
applications to Linux.
I do not know differences between setsockopt() and ioctl() enough to 
give you an advice, sorry.
Is there any way to force the authentication (encryption) for a L2CAP 
socket (at creation time for example) ?

Regards

Fred
