cups-1.4.2-alt0.M51.1

It'd be nice if cups advertised itself for zeroconf (a use case: http://blog.venthur.de/2007/08/17/howto-setup-a-print-server-for-windows-and-others-using-cups-and-zeroconf/ ).

But, as it can be seen in the "Advanced" view of https://localhost:631/admin in cups-1.4.2-alt0.M51.1, "dnssd" protocol is not available as a "Browse*Protocol" option.

Perhaps, that's because CUPS hasn't been compiled with avahi -- https://bugs.launchpad.net/ubuntu/+source/cups/+bug/465916/comments/1 .

dnssd advertising didn't work either in cups-1.3.9-alt2.

I tested it by switching it on in the web interface or in /etc/cups/cupsd.conf, and then looking through " avahi-browse -a" or "avahi-discover".

Собранный в АльтЛинукс cups не поддерживает Avahi, ведущую реализацию протокола dnssd под Linux

В http://git.altlinux.org/people/morozov/packages/cups.git?p=cups.git;a=shortlog;h=refs/heads/alm есть подготовленный пакет с патчем имени RH/Fedora, который решает эту проблему. Пакет выглядит работающим (с моей точки зрения)

Кроме того, следует подумать об инкорпорировании других патчей из Fedora, некоторые из них выглядят небесполезными.

The cups package in ALTLinux doesn't support Avahi, the leading DNSSD protocol implementation under Linux.

There's a prepared package in http://git.altlinux.org/people/morozov/packages/cups.git?p=cups.git;a=shortlog;h=refs/heads/alm with RH/Fedora-originated patch to solve this problem. The package looks working, at least for me.

BTW one should consider other patches from RH/Fedora as well, at least some of them worth attention.

Давайте-ка с этим на сизифный пакет, чтоб не потерялось.

It seems like current CUPS 1.6.2 does this already
