The CUPS server is a CentOS-6 box. I should have mentioned I can explicitly add the queue manually - it's only the "automagic" method of dns-sd that doesn't work
ie on the Ubuntu laptop "Printers->Add->ipp://cups.server.name/printers/queueName" works just fine, the queue is added and I can print to it * cups-browsed is running * avahi-daemon is running on the laptop and is not needed on the server. I am WAN connected to the server, so broadcast/multicast methods are never going to work - that's the entire point of me trying dns-sd :-). Instead we have manually installed dns-sd related DNS records pointing to the CUPS server * avahi-discover wasn't installed on the laptop. After I installed it (also installed avahi-discover as a dependency), running it produced a GUI containing lots of local broadcast-based stuff (eg iphones, vnc, ssh; both ipv4/ipv6). Right at the bottom was "WAN", opening that showed our corporate DNS domain, but double-clicking on it didn't do anything - nor did a sniffer show any dns-sd* lookups. There is no "Internet Printer" nor "ipp*" section I have winbind installed (the Ubuntu laptop is AD integrated) and can see it doing Active-Directory related DNS SRV lookups, so DNS is definitely working, and if I manually lookup records like dig ptr b._dns-sd._udp.our.domain ...then I get directed appropriately, and following the chain down the rabbit hole I end up with the appropriate TXT and SRV records needed to use that IPP queue. But as the laptop doesn't do the initial dns-sd lookups, that cannot happen The /etc/cups/cups-browsed.conf file has CreateIPPPrinterQueues commented out, I uncommented that and restarted cupsd/cups-browsed and saw some DNS lookups for _services._dns-sd._udp.our.domain - but we don't have any records in there (and Macs don't seem to use that) ** Attachment added: "cups-browsed.conf" https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1346118/+attachment/4159702/+files/cups-browsed.conf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1346118 Title: Printers app doesn't seem to do dns-sd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1346118/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
