1)
my home computer (the one with the internet connection) has:
device {
bdaddr 00:09:dd:50:0f:0a;
name "Mato Edimax";
key nokey;
pin "1234";
}
my work computer has:
device {
bdaddr 00:16:41:12:09:53;
name "Mato D820";
key nokey;
pin "1234";
}
Well, actually I've got the same hcsecd.conf with all the entries in
both computers.
2)
Just to be sure -- on which computer to run hcidump ?
I do not know how to share link keys between FreeBSD and Windows. Also,
as explained in my previous email, there are situations when sharing a
link key is not a choice.
However, Windows can manage this as it asks for PIN key when connection
initiation fails. While I don't expect FreeBSD asking for a PIN, it
might be quite useful if it could automatically (upon a connection
establishing failure) throw away its stored link key and recreate it
from PIN as Windows does. This would definitely help as it is basically
what I have to do manually after each Windows run (that is to say ..
stop hcsecd, rm hcsecd.keys, start hcsecd).
With regards,
Martin
