Openhab Executecommandline permissions

[NCO (E. Gerland)]

Just got it - same problem like in a very early stage of OH:

Access right problem (bluetooth dongle)

The problem seems to be more on the lower level: When I run the script and use inside it a sudo command: if /usr/bin/sudo /usr/bin/l2ping -c 1 $MAC to check for the BT devices, I get the response: sudo: no tty present and no askpass program specified Any idea what this means?

Sorry for my low performance brain.
