I noticed that the internal firewall blocks by default for CUPS printers in the network.
Is this by the design or is it a bug?
The external zone by default has no ports open. That's intentional of course.
Printing to a printer needs opening ports? :-?
No, it does not.
I thought we needed opening the port only if other computers wanted to print to "my" cups.
You need to open TCP port 631 to be able to accept printing jobs from remote hosts. You need to open UDP port 631 to accept IPP broadcasts announcing presence of printing servers and their queues. This is a comfortable way to have all available network queues available when roaming between multiple networks, but it is not necessary in order to print to a remote host at all.
If it needs opening a port, shouldn't yast automatically open it, or at least, advise to open it, as soon as it knows I want to use a network printer?
I couldn't finish configure the printer, yast only works in ncurses mode (known bug) and I couldn't figure out what was happening. It could be because of closed port, dunno.
Please, file a bugreport about this and attach the logs. -- Regards, Jiri Srain YaST Team Leader --------------------------------------------------------------------- SUSE LINUX, s.r.o. e-mail: jsrain@suse.cz Lihovarska 1060/12 tel: +420 284 028 959 190 00 Praha 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz
