Cups как принт-сервер. «Unable to connect to server »


0

0

Уже 9 часов как пытаюсь в своей локальной сети (хе, состоящей из двух компов соединённых напрямую) открыть доступ от одного cups'а (под AltLinux, в данном случае клиент) к другому (Arch, --//-- сервер).
Из под Arch всё печатает, пинги идут, сервер через клиента ходит в интернет (т.е. проблем с настрокой самого принтера и сети не должно быть).
Проблема в следующем: клиент ни в какую не видит сервер с его принтерами, хотя уже на третий раз прописал всё как надо (а точнее как советуют все статьи что я нашёл и все мои...3 книги :) ), но всё равно "не выходит каменный цветок"...

На клиенте пишет следующее:
[root@localhost rap-kasta]# LANG=C lpstat -v
lpstat: Unable to connect to server

На сервере в логах тишина (по крайней мере я это считаю тишиной, до этого были проблемы с Avahi и DNS-DS, но запуск авахи их поправил таки :-) )

Вот конфиги:

Вот "голые логи", т.е. логи удалил и cups'ы перезапустил (оба, на сервере включен debug режим).

Re: Cups как принт-сервер. "Unable to connect to server "

Методом научных извращений было выясненно, что lpstat -v пытается достучаться до днс-прова...непонятно зачем и мне пока непонятно как с этим бороться...

Re: Cups как принт-сервер. "Unable to connect to server "

Рецепт.
Поднимаем на локалхосте cups. Заново, начисто, чтобы старых косяков не осталось.
Печатаем.
Идем в http://localhost:631/admin
Ставим галку в "Share published printers connected to this system"
Применяем изменения.

На соседнем компе, клиенте, cups сносим нафиг. Cups ставить на клиенте для печати вообще не надо !!!, достаточно иметь libcups*. А эти либы уже, наверное, есть.

На клиенте заводим 1 (один) файлик:
$ cat /etc/cups/client.conf
ServerName 192.168.1.10

Айпишник пропишите своего cups сервера.
Открываем чегонить в браузере. Жмем "Печать". Выбираем внезапно появившийся удалённый принтер. Печатаем.

Курим маны и конфиги и думаем, как оно работает.
