Note: Initial bug report was made under 12.10, but the following retest performed under 14.04.1.
We seem to have a couple of different problems, both indicating a lack of IPv6 support. 1) Scanner detection over the network is performed with BJNP, and the specification seems to be tied to using IPv4 broadcast. 2) Manual specification of the scanner in the backend configuration is unsuccessful: kjotte@daedalus:~$ cat /etc/sane.d/pixma.conf # pixma.conf configuration for the sane pixma backend # # define URI's of scanners (one per line) # This is only used for network scanners. # normally scanners will be detected by sending a broadcast # if this does not work under your OS, or if the scanners # are on a different subnet, configure your scanners URI here # # method must be bjnp # port number can normally be left out, port 8612 is used as default # Example: # bjnp://myscanner.my.domain:8612 # bjnp://printer-1.pheasant.org # bjnp://gonzo.mibloving.net kjotte@daedalus:~$ scanimage -L [pixma] Cannot resolve hostname: gonzo.mibloving.net 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). kjotte@daedalus:~$ host gonzo.mibloving.net gonzo.mibloving.net has IPv6 address 2001:470:8:f04:8a87:17ff:fe3b:fe0d -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1160650 Title: cannot detect IPv6 scanner Status in “sane-backends” package in Ubuntu: Confirmed Bug description: A network scanner running only in IPv6 mode cannot be detected by SANE. $ avahi-browse -av Server version: avahi 0.6.31; Host name: scooter.local E Ifce Prot Name Type Domain ... + wlan0 IPv6 Canon MX870 series _3E420E3BFE0D _scanner._tcp local $ scanimage -L scanimage: no SANE devices found However, if the device is configured for IPv4, it is visiable to SANE: $ avahi-browse -av Server version: avahi 0.6.31; Host name: scooter.local E Ifce Prot Name Type Domain ... + wlan0 IPv4 Canon MX870 series _3E420E3BFE0D _scanner._tcp local $ scanimage -L device `pixma:MX870_gonzo' is a CANON Canon PIXMA MX870 multi-function peripheral The device in question can only operate in one mode or the other, not dual-stack. We would prefer to use IPv6 wherever possible in our environment, so this is a blocker.
