I don't think that this is needed. The magic is done by the --msdun
switch.

No need for that, because dund will do that for you if not told
otherwise.

Run "hcidump -X -V" in another terminal to see what happens.

Well....i succesfully made this connection earlier on another distro
(fedora - now i am on ubuntu) with the same devices, same settings,
and /etc/ppp/at-cmd.pl was "a must" to connect.

Looks like this script isn't executed. At least it doesn't appear in
log file as it should:

Here are hcidump logs with and without DUN service registered before
connection attempt:

http://grudziadz.org/hcidump_without_DUN_regietered.log

the PDA sends AT commands and not the magic CLIENTSERVER string. So you
may wanna try it without the --msdun switch.

Works without --msdun and with this magic at-cmd.pl script like a charm :) =
Thnx.
This was probably not server-side problem, but (terrible) bluetooth
stack upgrade on my pda.

Thnx one more time for a hint.

BTW. You said it shoudn't be nessesary to register DUN service with
'/usr/local/bin/sdptool add DUN' on every bluetooth start? Well, i
cannot connect without it, but it should be done with dund, right?

you are welcome.

You don't need it, because dund is registering the record when it starts
up. However it might be buggy. Use "sdptool browse --raw local" to see
if there are any differences in the records. Make sure that you really
start the sdpd and dund from bluez-utils-2.23 and don't have an old copy
somewhere in /usr/bin or /usr/sbin.

Regards

Marcel
