[Bluez-users] Ultimate PAN howto. Where?

[Bluez-users] Ultimate PAN howto. Where?

[M]

Hello, I'm trying to get PAN running, NAP on linux, 2 PANUs on windows. 
There is no problem with the windows boxes, it gives me headaches to set 
up the linux box however. I got everything running quite fine with just 
one client using non-briged routing, now I would like to bridge bnepX 
and eth0 interfaces so that:

- IP addresses are asigned by DHCP
- it's possible to connect to internet from NAP box (after following one 
howto it wasn't possible)
- everything is automatic - after the setup anyone should be able to 
turn on the NAP box and connect, even without an account.

Please, direct me to the right howto, tell me which parts to skip and 
what to do another way.

Thank you

actually the automatic part is distribution specific, because you need
to create the bridge at startup and run the dedicated DHCP server. You
also need to make sure the bnepX devices are added/removed to the bridge
when pand accepts a new connection.

After experimenting I got bridge + DHCP working, it's not automatic but 
that does not matter now anyway, cause I had to change it back.

If remote device disconnects, the bnepX interface is not fully unregistered:

[/var/log/messages]:

kernel: pan0: port 1(bnep0) entering disabled state
net.agent[12626]: remove event not handled
kernel: unregister_netdevice: waiting for bnep0 to become free. Usage 
count = 1

The last message is repeated at regular intervals.

`brctl show` shows bnep0 in pan0 bridge interface

`brctl delif pan0 bnep0` results in "interface bnep0 does not exist!"

`ifconfig` or `ifdown bnep0` freeze up

I can't even turn of the computer regulary, I have to hard reset it.

Is this a bug?

sounds like a bug in the bridge code. What kernel do you use?
