<div dir="ltr">Here's the original message again, removing the formatting from the original forum website version that didn't seem to work. Lots of the original content went missing. Sorry for the double post if it did work for you originally. I've also added my config file to the end of this message, so it's huge.<div>---</div><div><div>I've had a Canon MG8150 attached to my network for ages and decided to hook it up to my network box (Fedora 23), basically hoping to automatically save scans to my network drive when I press the scan button on the machine. </div><div><br></div><div>I followed various articles around the place to try and set this up but I seem to have failed. Here's a summary of where I'm up to - would love some help troubleshooting the problem: </div><div><br></div><div>- Have installed sane-backends-devel via dnf, and scanbd 1.4.4 from source (using default configure / gmake approach, no options). </div><div>- Copied the /etc/sane.d/* files to /usr/local/etc/scanbd/sane.d/ </div><div>- added a symbolic link from /etc/scanbd to /usr/local/etc/scanbd just in case anything refers to that. I prefer working in usr to etc directly. </div><div>- Changed /etc/sane.d/saned.conf to only allow localhost </div><div>- Changed /usr/local/etc/scanbd/sane.d/saned.conf to allow all local network clients </div><div>- Changed /etc/sane.d/net.conf to have 2 lines, connect_timeout = 3 and localhost </div><div>- Changed /etc/sane.d/dll.conf to have only net </div><div>- Changed /etc/local/etc/scanbd/sane.d/dll.conf to comment out net, and remove the unnecessary references (just kept pixma) </div><div>- Saved scanbd_dbus to /etc/dbus-1/system.d/scandb_dbus.conf </div><div>- Create systemd files /usr/lib/systemd/system/scanbd.service and scanbm.socket. Only change is to add the revised sane.d config directory. </div><div><br></div><div>scanbd.service:</div><div> </div><div>[Unit]</div><div>Description=Scanner button polling Service</div><div><br></div><div>[Service]</div><div>Type=simple</div><div>ExecStart=/usr/local/sbin/scanbd -f -c /usr/local/etc/scanbd/scanbd.conf</div><div>#ExecReload=?</div><div>Environment=SANE_CONFIG_DIR=/usr/local/etc/scanbd/sane.d</div><div>StandardInput=null</div><div>StandardOutput=syslog</div><div>StandardError=syslog</div><div>#NotifyAccess=?</div><div><br></div><div>[Install]</div><div>WantedBy=multi-user.target</div><div>Also=scanbm.socket</div><div>Alias=dbus-de.kmux.scanbd.server.service</div><div><br></div><div>My scanbd.conf file is default, with some minor amendments.
