[sane-devel] scanner is no longer recognized over network

Wed Jul 28 12:02:10 UTC 2010

[net] sane_open: net_open
[net] sane_open: remote open failed
scanimage: open of device net:192.168.0.102:pixma:04A91709 failed: Access to
resource has been denied
[net] sane_exit: exiting
What about the xinet (or inet ?) configuration you are using on the server:
is the user/group used for saned allowed to use the scanner on usb ?
