I raised the loglevel even to debug2, but I see no trace at all of the calls to smb when I do "journalctl -e" I see traces of the job I send but all of them with the uri ipp://localhost... I see no errors there. >>You can also try modifying the script to: >>#!/bin/sh >>/usr/bin/logger -t "${0}[${$}]" "Called with [${@}]" >>/usr/bin/logger -t "${0}[${$}]" "DEVICE_URI=[${DEVICE_URI}]" >cat - | /usr/lib/cups/backend/smb.real "${@}" Entering these lines in the script, gave me nothing: no trace of the logs when running "journalctl -e" How can I check if samba is called correctly? regards Jouk Pax, vel iniusta, utilior est quam iustissimum bellum.
