Hello,
I'd like to know if it is possible to have a computer that does
button-triggered scanning via scanbd but also exports the scanner over
the network to be accesible via the common. How would one do that?
Well, absolutely: thats the whole story of scanbd (see the readme.txt of
scanbd).
Well, I am aware of the general idea how saned and scanbd are supposed
to interact. It can be pretty complicated to configure this error-free.
Going from one machine back to a real network adds yet another layer
of complexity (and I was bitching when getting saned over network to run
for the first and a couple subsequent times).
As you probably know, I added a couple of checks for common
configuration errors to the Debian scanbd startup script. Anything
detected by
http://anonscm.debian.org/cgit/collab-maint/scanbd.git/tree/debian/scanbd.init
is OK on my scanbd server machine. Button presses are detected fine by
scanbd. But with this configuration, the scanner will only be detected
by sane-find-scanner and not be "scanimage -L".
$ sane-find-scanner | grep ^found
found USB scanner (vendor=0x04a9 [Canon], product=0x2213 [CanoScan]) at
libusb:001:035
Should this really be libusb?
Only if I add the genesys backend to /etc/sane.d/dll.conf, shut down
scanbd and start up saned do I get an output from "scanimage -L".
$ scanimage -L
device `genesys:libusb:001:035' is a Canon LiDE 35/40/50 flatbed scanner
That's when I also get a response from a network-connected client.
$ scanimage -L
device `net:himbeere.local:genesys:libusb:001:035' is a Canon LiDE
35/40/50 flatbed scanner
So, what am I likely doing wrong here? Any idea?
When scanbd is running (and thus scanimage is broken locally as well as
over the network), the following is the status:
- scanbd service is running
- saned service is stopped
- /etc/sane.d/dll.conf contains only the net backend
- /etc/scanbd/dll.conf does NOT contain the net backend
- /etc/scanbd/dll.conf contains the necessary genesys backend
(and a few others)
Regards
Rolf
