PIN code request fails due to error in /usr/bin/pinwrapper

[John Gaughan]

Binary package hint: bluez-utils

Hi,

the "!" is missing from the shebang line of /usr/bin/pinwrapper. This causes it to fail when called by hcid with this error:
    May 16 23:08:45 morbius hcid[14173]: PIN helper exited abnormally with code 256

This is with bluez-utils 2.24-0ubuntu6 in dapper.

Can be easily corrected

[Emmet Hikory (persia)]

The attached patch adds the required ! to pinwrapper.

[Peter Meiser (meiser79)]

Emmet: shouldn't the ! be after #, not before?

[Emmet Hikory (persia)]

Yes. Sorry.

[Matthias Grüter (mgrueter)]

Are you sure the problem lies in pinwrapper? I still got the same error ("PIN helper exited abnormally") after using the corrected patch.
However the following explanation applies to me: http://ubuntuforums.org/showthread.php?t=113903
According to this "the pin helper program that prompts you for a PIN cannot connect to your display because it is running as root". By running "xhost +" this can be solved. However this is a ugly trick and should have been set up differently in the first place.

[Pete Ryland (pdr)]

Note that running "xhost +" is really not recommended. In some cases, you're opening a big security hole, allowing anyone to connect to your machine's X server. Someone can log you out for example. For the above problem, doing "xhost +localhost" is a *much* safer option. The DISPLAY environment variable may not be set correctly anyway.

Anyway, the more recent versions use dbus for the pin instead. pinwrapper is obsolete now.
