Hello,

I tried to comply with the bug report guidelines found at=20
http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html

[1] device node rfcomm0 is removed by sysfs upon ppp disconnect, but not=20
created on connect

[2] I am connecting a palm Tungsten T to my linux box using bluetooth (blue=
z=20
stack). I am using dund to listen for incoming connections. My problem is,=
=20
that the device node rfcomm0 is not created automatically. However, if I=20
create it manually, it is removed upon termination of the connection, by=20
sysfs presumably. Creating the node manually, the connection works fine.

In my rfcommd.conf settings, I have set:
rfcomm0 {
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0bind no;
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0device <btaddr of palm>;
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0channel 1;
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0comment "Tungsten";
}

which appears to be the problem. Setting "bind yes;" will cause the device=
=20
node to be created, but the connection fails, presumably because the Tungst=
en=20
does not allow binding.

I also tested bluetooth connectivity with my cellphone. issuing the command
rfcomm bind 3 <btaddr of cellphone> works and also creates the device=20
node /dev/rfcomm3.

[3] bluetooth rfcomm sysfs

[4] 2.6.5

I will be happy to provide the rest upon request, but deem it too long to p=
ost=20
it initially

Regards,

Christoph Burger-Scheidlin
