[sane-devel] scanbd problem with dbus permission ?
Hi Wilhelm, I figured out the problem: it's about the permissions. It seems to be this issue: http://sane.10972.n7.nabble.com/scanbd-works-but-not-buttons-td16867.html - edit scanbd.conf user = root, group = root - login as root, sudo su - export SANE_CONFIG_DIR=/usr/local/etc/scanbd - /usr/local/sbin/scanbd -d -f -c /usr/local/etc/scanbd/scanbd.conf Now I see the debug output and the pressed buttons.

[sane-devel] scanbd problem with dbus permission ?
Hi, I tried to install scanbd and I guess that's very easy, but now I have a permission problem. In the past I use my scanner with sane as scanserver and everything worked. My system: Debian Wheezy, Kernel 3.6.11 on Raspberry Pi Scanner: Canon canoscan lide 35 Here my installation steps: - install libconfuse-dev libsane-dev libudev-dev libusb-dev - I use scanbd from SVN - ./configure --enable-scanbuttond (no problems) - make (no problems) - make install (no problems) - copy scanbd_dbus.conf to /etc/dbus-1/system.d/ - install xinetd - generate /etc/xinetd.d/sane-port - edit /etc/sane.d/dll.conf set only net - edit /usr/local/etc/scanbd/dll.conf set #net - edit /etc/sane.d/net.conf set localhost and connect_timeout = 60 - copy backends /etc/sane.d/ to /usr/local/etc/scanbd/ - export SANE_CONFIG_DIR=/usr/local/etc/scanbd - /usr/local/sbin/scanbd -d -f -c /usr/local/etc/scanbd/scanbd.conf (with problems) Log: /usr/local/sbin/scanbd: debug on: level: 7 /usr/local/sbin/scanbd: dropping privs to uid saned /usr/local/sbin/scanbd: dropping privs to gid lp /usr/local/sbin/scanbd: drop privileges to gid: 7 /usr/local/sbin/scanbd: Can't set the effective gid to 7 /usr/local/sbin/scanbd: drop privileges to uid: 112 /usr/local/sbin/scanbd: Can't set the effective uid to 112 /usr/local/sbin/scanbd: dbus_init /usr/local/sbin/scanbd: dbus match type='signal',interface='org.freedesktop.Hal.Manager' /usr/local/sbin/scanbd: Loading /usr/local/lib/scanbd/scanbuttond/backends/meta.so /usr/local/sbin/scanbd: meta-backend: init /usr/local/sbin/scanbd: libusbi: initializing... /usr/local/sbin/scanbd: Loading /usr/local/lib/scanbd/scanbuttond/backends/hp3500.so /usr/local/sbin/scanbd: meta-backend: attaching backend: HP3500 USB /usr/local/sbin/scanbd: hp3500-backend: init /usr/local/sbin/scanbd: Loading /usr/local/lib/scanbd/scanbuttond/backends/snapscan.so /usr/local/sbin/scanbd: meta-backend: attaching backend: Snapscan USB /usr/local/sbin/scanbd: snapscan-backend: init /usr/local/sbin/scanbd: Loading /usr/local/lib/scanbd/scanbuttond/backends/niash.so /usr/local/sbin/scanbd: meta-backend: attaching backend: Niash USB /usr/local/sbin/scanbd: niash-backend: init /usr/local/sbin/scanbd: Loading /usr/local/lib/scanbd/scanbuttond/backends/epson_vphoto.so /usr/local/sbin/scanbd: meta-backend: attaching backend: Epson VX00 Photo USB /usr/local/sbin/scanbd: epson-vphoto-backend: init /usr/local/sbin/scanbd: Scanning for local-only devices /usr/local/sbin/scanbd: Can't get the scbtn device list /usr/local/sbin/scanbd: device list null /usr/local/sbin/scanbd: start_scbtn_threads /usr/local/sbin/scanbd: start the threads (0) /usr/local/sbin/scanbd: start dbus thread /usr/local/sbin/scanbd: Not Primary Owner (-1) /usr/local/sbin/scanbd: Name Error (Connection :1.48 is not allowed to own the service de.kmux.scanbd.server due to security policies in the configuration file) If I started scanbd as sudo: Log: ... /usr/local/sbin/scanbd: meta-backend: attaching backend: Epson VX00 Photo USB /usr/local/sbin/scanbd: epson-vphoto-backend: init /usr/local/sbin/scanbd: Scanning for local-only devices /usr/local/sbin/scanbd: Can't get the scbtn device list /usr/local/sbin/scanbd: device list null /usr/local/sbin/scanbd: start_scbtn_threads /usr/local/sbin/scanbd: start the threads (0) /usr/local/sbin/scanbd: start dbus thread /usr/local/sbin/scanbd: timeout: 500 ms /usr/local/sbin/scanbd: Iteration on dbus call /usr/local/sbin/scanbd: Iteration on dbus call /usr/local/sbin/scanbd: Iteration on dbus call /usr/local/sbin/scanbd: Iteration on dbus call /usr/local/sbin/scanbd: Iteration on dbus call /usr/local/sbin/scanbd: Iteration on dbus call I tried also too: - SANE_CONFIG_DIR=/usr/local/etc/scanbd scanimage -L (with problems) - copy 99-saned.rules to /lib/udev/rules.d - udevadm trigger - SANE_CONFIG_DIR=/usr/local/etc/scanbd scanimage -L (with problems) - sudo SANE_CONFIG_DIR=/usr/local/etc/scanbd scanimage -L (no problems) I'm not familiar with dbus and so on... Can someone help me please? Thanks, Michael
[sane-devel] scanbd problem with dbus permission ?
Hello, A few notes: scanbd_dbus shall be copied into /etc/dbus-1/system.d, that is what you referred to I guess? Yes it is. What do you use to start scanbd? Systemd? Scanbd apparently does not see the scanner. What is set for SANE_CONFIG_DIR? Do you have a dll.conf in that dir with the appropriate backend for your scanner listed? Does it have the config file for the backend (if needed) in that dir? Yes, I use systemd to start scanbd. No, the SANE_CONFIG_DIR wasn't set. I just try to set it manually (with export command), pointing to the scanbd folder, where a dll.conf is, but it did not change anything : if I launch directly scanbd, Iteration on dbus call , if I do a scanimage before launching it, everything works just fine... Thank you for your attention, Best regards, stout

No, the SANE_CONFIG_DIR wasn't set. 1) For scanbd (and scanbm) it should be set in the service files in (/usr)/lib/systemd/system/scanbd.service or scanbm at .service: Here is my scanbd.service: [Unit] Description=Scanner button polling Service [Service] Type=simple ExecStart=/usr/sbin/scanbd -f #ExecReload=? Environment=SANE_CONFIG_DIR=/etc/scanbd StandardInput=null StandardOutput=syslog StandardError=syslog #NotifyAccess=? [Install] WantedBy=multi-user.target Also=scanbm.socket Alias=dbus-de.kmux.scanbd.server.service see the environment setting. Please note that the config dir must be different for scanbd and the user. This is why we set it here for scanbd (and in scanbm.service for scanbm) and point it to the directory where we have a dll.conf with reference to the backend for the scanner and (if needed) the xxx.conf for the backend. 2) For the user we need a dll.conf in the normal location (often /etc/sane.d) where the dll.conf only has net and the net.conf (with appropriate customization) kind regards Louis

Hello,
I found some solution for my problem :
First, I noticed than the file scanbd_dbus.conf wasn't in the system.d
folder, so I added it.
The error changed : no more dbus connection error but endless
Iteration on dbus call in the log...
It seems that if I start scanbd right after inetd, this error shows.
Bur if I start inetd, then do a scanimage -L or another use of the
scanner via sane, then start scanbd, it works like a charm !
So I modify the udev rule so that when the scanner is turned on, it
launches inetd, then imagescan -L, then scanbd :
# Epson Perfection V500 Photo
ENV{ID_VENDOR_ID}==04b8, ENV{ID_MODEL_ID}==0130, ACTION==add,
RUN+=/usr/sbin/service inetutils-inetd start,
RUN+=/usr/bin/scanimage -L, RUN+=/usr/sbin/service scanbd start
ENV{ID_VENDOR_ID}==04b8, ENV{ID_MODEL_ID}==0130, ACTION==remove,
RUN+=/usr/sbin/service scanbd stop, RUN+=/usr/sbin/service
inetutils-inetd stop
I don't know if it is a configuration problem or a bug...

I tried to modify the user/group in scanbd.conf (trying lp, saned,

The UDEV rule for the scanner seems to make it belong to the
scanner group : ATTRS{idVendor}==04b8,
ATTRS{idProduct}==0130, MODE=0664, GROUP=scanner,
ENV{libsane_matched}=yes
Don't hesitate to ask me for more informations if needed...

this should not be required, but you need to set the SANE_CONFIG_DIR
env. variable before starting scanbd (see below)
I don't know if it is a configuration problem or a bug...
