Hi All
I installed Tumbleweed recently and am trying to get my printers to work. I have a Brother HL-L2305W laser printer and an Epson XP-442 colour dot matrix printer.
I spent a lot of time trying to get them to connect but had no luck at all. Eventually I tried turning off the firewall, and amazingly they both worked. A bit more RTFMing told me I needed to enable mdns and ipp in the firewall to allow the printers to work while the firewall was active, so I did that but the firewall is still blocking the printers. The only way I can print is to turn off the firewall first.
My question is, what do I have to add to the firewall setting to allow the printers to work?
Thanks.
You should start by showing the existing firewall configuration:
firewall-cmd --list-all-zones
Check that the network interface of interest is in the applicable zone, and that the configuration was made to the appropriate zone as well.
@deano_ferrari thanks for the quick reply.
I found the problem.
When I first installed Opensuse and looked at the firewall (using yast firewall), there was only one interface defined, called ‘docker0’. I had no idea what that was, so basically ignored it. The command you suggested showed me all the zones, and the first thing I noticed was that most of them didn’t have an interface defined. A zone called ‘docker’ did, and it was ‘docker0’. However another one, ‘public’, had an interface ‘eno1’ set. This looked a bit like an interface name to me, so I added the ‘home’ zone (in the ‘interfaces’ tab in yast firewall’) with an interface name of ‘eno1’, and printing now works.
I can’t figure out how to delete the docker0 one, but I guess it doesn’t matter.
Anyway thanks for pointing me in the right direction.
As suspected. Glad to have been of guidance.
That comes as part of firewalld. Just ignore it.
Consider it ignored.
Love the nick BTW. Mine is car related too but not so obvious maybe. I’m a fan of the English car marque Morgan, and their flagship car the Plus 8. In England Morgans are known as mogs, hence the nick. Sort of. I signed up to the Suse forum years ago with my standard nick, mogplus8, with an email I no longer have access to, and despite my best efforts I wasn’t able to get it changed to my current email. So the easiest thing was to create a new account. With an extra ‘8’.
