What are you using to start the daemon (systemd, inetd, sysvinit)? Can you add the command-line option "--debug=5" and post the same part of the system log? ** Bug watch added: gitlab.com/sane-project/backends/-/issues #499 https://gitlab.com/sane-project/backends/-/issues/499 -- 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/1888928 Title: "getaddrinfo for local hostname failed: No address associated with hostname" for IPv4 to IPv6 converted address Status in sane-backends package in Ubuntu: New Bug description: I am trying to setup saned for remote scanning, but without luck. On server side I have allowed 192.168.1.0/24 subnet, but remote host does not find a scanner. During investigation I found the following in server's logs: Jul 25 11:40:42 X saned[4167]: bailing out, waiting for children... Jul 25 11:40:42 X saned[4167]: bail_out: all children exited Jul 25 11:40:42 X saned[4299]: saned (AF-indep+IPv6) from sane-backends 1.0.30 starting up Jul 25 11:40:42 X saned[4299]: do_bindings: [0] bind failed: Address already in use Jul 25 11:40:42 X saned[4300]: Now daemonized Jul 25 11:40:43 X saned[4314]: check_host: access by remote host: ::ffff:192.168.1.2 Jul 25 11:40:43 X saned[4314]: check_host: getaddrinfo for local hostname failed: No address associated with hostname Jul 25 11:40:43 X saned[4314]: init: access by host ::ffff:192.168.1.2 denied Jul 25 11:40:43 X saned[4314]: quit: exiting It looks to me like it is treating the IPv4 to IPv6 converted address as a hostname and trying to resolve it, what of course fails. This looks like a bug for me. Adding "::ffff:192.168.1.2" to access list does not resolve the problem. # sysctl -a | grep "net.ipv6.bindv6only" net.ipv6.bindv6only = 0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1888928/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
