[sane-devel] Canon MP600R - Connection via LAN

[Michael Brasse]

Hello everybody,
Attempts to connect to the scanner via the network was not successful.

If I manage I am happy to provide test reports etc.

If that is not the right place to ask, please refer - otherwise I am
happy for any ideas.

The problem I have is:
sandmann:/etc/sane.d # SANE_DEBUG_NET=128 scanimage -L
[sanei_debug] Setting debug level of net to 128.
[net] sane_init: authorize = 0x804d560, version_code = 0xbff301d8

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
[net] sane_exit: exiting
[net] sane_exit: closing dev 0x8054f68, ctl=-1
[net] sane_exit: finished.

also:
sandmann:/etc/sane.d # telnet 192.168.0.2 6566
Trying 192.168.0.2...
telnet: connect to address 192.168.0.2: Connection refused

Printing works, ping works, the web-server of the device works, there
is no firewall running on my machine - but scanning doesn't work.

This is what I have configured (this is all I know):

sandmann:/etc/sane.d # cat net.conf
# This is the net config file.  Each line names a host to attach to.
# If you list "localhost" then your backends can be accessed either
# directly or through the net backend.  Going through the net backend
# may be necessary to access devices that need special privileges.
# localhost
192.168.0.2

sandmann:/etc/sane.d # cat dll.conf
# enable the next line if you want to allow access through the network:
net
#abaton
#agfafocus
#apple
...

sandmann:/etc # cat services
...
#               6559-6565  Unassigned

#               6567-6578  Unassigned

Thanks for any hint.

Best regards
