[Bluez-users] Anonymous service setup

[Bluez-users] Anonymous service setup

[Christoph Simon]

Hi,

I was asked to set up a linux (debian) box, which has an usb bluetooth
dongle, and which would allow anyone passing by and having a bluetooth
enabled device, to fetch some file from the server.

Unfortunately, I'm really stuck with all this, too many TLAs. I
managed to run hciconfig listing the dongle, to scan and inquire a
cellphone and to use l2ping on the MAC address. But there doesn't seem
to be a way to make a basic filetransfer.

When trying with obexftp, the celphone will asked for a PIN, when I
enter that which is written in /etc/bluetooth/pin, but then it just
hangs. In daemon.log, I can see the messages from hcid
"link_key_request" and "pin_code_request" but nothing else. After some
time, both obexftp desists, and the Motorola celphone would reboot. I
have been looking for some sort of debug mode of hcid, but couldn't
find any flag. I also changed the pin_helper line in the config file
to be a shellscript which just outputs "PIN:1234", but still doesn't
work. (the script is executable and works on the shell).

Thus, my first question is, what do I need to do to make this work. I
should work, right? And the second question is, what kind of service I
would have to setup, such that anybody can get some files prepared on
that server, with the minimum hassle of typing pincodes.

Thanks,

-- 
Chris

Many phones do not require authentication for OBEX Push.  You might try to
use that instead of OBEX File Transfer to avoid the PIN issue.  take a look
at ussp-push.

Thanks, Albert, and sorry for taking so long to check it
out. Unfortunately, ussp-push also requires a PIN. This is exactly
what I tried. First:

	obexftp -b 00:15:A8:F3:B5:DF -l
	Browsing 00:15:A8:E3:A5:DF ...
	Channel: 9
	No custom transport

Here the phone askes if I want to connect and I say Yes. Then it asks
me for a PIN which I type in (the same which is in /etc/bluetooth/pin)
and the phone tells me that the PIN is invalid. I can try the same or
any other...

	Connecting...failed: connect
	Still trying to connect
	Connecting...failed: connect
	Still trying to connect
	Connecting...failed: connect
	Still trying to connect

until, eventually, they give up. Then, with ussp-push:

	ussp-push --dev hci:0 00:15:A8:F3:B5:DF@1 test.jpg test.jpg
	pushing file test.jpg
	name=test.jpg, size=1377
	Registered transport

	set user data

	created new objext
	Local device 00:10:60:AA:BA:53
	Remote device 00:15:A8:E3:B5:DF (1)

Here I'm asked by the phone to type in the PIN.

	connect: Connection refused
	Link broken!

	started a new request
	Error while doing OBEX_HandleInput()
	Connection return code: -1, id: 0
	Local device 00:10:60:AA:BA:53
	Remote device 00:15:A8:C3:A5:DF (1)
	connect: Connection refused
	Link broken!
	Error while doing OBEX_HandleInput()unable to connect to the
	server error

ObexFTP is version 0.10.8, ussp-push is version v0.5.

What else could I try?

Thanks,
