[sane-devel] scanbd problem with dbus permission ?

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

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...
Best regard

[sane-devel] scanbd problem with dbus permission ?

Hello,
Something strange happened :
2 months ago,I managed to get scanbd to work perfectly with my epson
V500 scanner, built my own script, ..., was very proud of myself...
... until today, where after 2 months of not using it, I tried to use
a button, and it did not work !!
I must have changed something, during those 2 months, but I really
don't know what...
So, the scanner is plugged in a Debian 6,
the debug log shows these errors :
scanbd: start dbus thread
scanbd: Not Primary Owner (-1)
scanbd: Name Error (Connection ":1.8" is not allowed to own the
service "de.kmux.scanbd.server" due to security policies in the
configuration
and later :
scanbd: polling device Perfection V500
scanbd: epson-vphoto-backend: communication error: read length:0
(expected:1)
(the full log is pasted afterwards)
I tried to modify the user/group in scanbd.conf (trying lp, saned,
scanner, root..) with no change.
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...
Thanks for your help !
