Samsung SCX-4623F Backend & Frontend work -- but not together

[mbwd]

My setup:
Kubuntu 13.10
Samsung SCX-4623 connected via USB to router with dd-wrt installed

I can scan directly from USB on the Linux side and "scanimage -L" recognizes the scanner if it is connected directly to the Linux computer's USB.

The dd-wrt router has sane installed (directions here http://www.dd-wrt.com/phpBB2/viewtopic.php?p=677441) and works.  The router passes all test with the Samsung connected and "scanimage -T" entered via telnet.  From the router, "scanimage -L" reports:

device `xerox_mfp:libusb:001:003' is a Samsung Samsung SCX-4623 Series multi-function peripheral

But I can't get the Linux computer to recognize the scanner over the network.


I did edit the "/etc/sane.d/xerox_mfp.conf" file with variations on "IP 10.0.1.7," " tcp 10.0.1.7," all to no avail. 

I tried: "/opt/Samsung/mfp/bin/Configurator&"
and got:

Any ideas?   I would love to get this working over my network!

What is the output of "/opt/Samsung/mfp/bin/netdiscovery --all --scanner"?

[mbwd]

Hi.  Thanks for the response.   Here is the output from "/opt/Samsung/mfp/bin/netdiscovery --all --scanner":

# DEBUG: Network printers discovery utility

[mbwd]

Did that help?  If you have a suggestion, I am all ears.

Note:  I also tried "/opt/Samsung/mfp/bin/netdiscovery -s --snmp" as suggested in Section 6 here (http://www.bchemnet.com/suldr/scanning.html), but got the same output.  Unfortunately, I can't tell from Section 6 what that means or the next steps . . . .

[bchemnet]

I don't know what is causing this problem.  My best guess is something in the current version of libsane (sane-backends) that is shipping with 13.10 and 14.04.  There are two other similar threads going in these forums right now about this, but I can't see much in common except a version of libsane that has a couple of extra patches not applied in previous releases or in the Debian series of packages.  My best suggestion now is to file a bug report with Ubuntu against the package, although honestly I wouldn't expect much of a response.

Sorry I can't be more help.

[mbwd]

Ok.  Thanks for the help.
