https://bugzilla.novell.com/show_bug.cgi?id=757354 https://bugzilla.novell.com/show_bug.cgi?id=757354#c0 Summary: hp-setup is unable to discover network printers except by IP address Classification: openSUSE Product: openSUSE 12.2 Version: Milestone 3 Platform: PC OS/Version: openSUSE 12.2 Status: NEW Severity: Normal Priority: P5 - None Component: Printing AssignedTo: jsmeix@suse.com ReportedBy: malv_star@hotmail.com QAContact: jsmeix@suse.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:11.0) Gecko/20100101 Firefox/11.0 After starting hp-setup from the command-line, the GUI program so launched is unable to discover printers on the network except by IP address, even when an exception is explicitly added to the firewall for the purpose of network discovery. Reproducible: Always Steps to Reproduce: 1. Start YaST from within KMenu and select "Firewall" 2. In "Allowed Service" add "mDNS/Bonjour support for HPLIP" 3. Start the program "hp-setup" from the command line, either as root or as a regular user 4. Select the option "Network/Ethernet/Wireless network" 5. Click on "Show Advance Options" 6. The only discovery method that will be always be successful is to select "Manual Discovery" and then specify an IP address for the printer, though sometimes using only the hostname for the printer (assuming you are running an internal DNS server) may find the printer (using the full host and domain name for the printer eg. printer.company.site will not be successful) 3. Actual Results: The GUI program will display the message "No Devices Found" Expected Results: The printer is displayed in the discovered devices list. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This means that the issue here is the SUSE firewall. I make this assertion because enabling mDNS/Bonjour for HPLIP in the firewall settings used to work, and now it does not. Instead you must disable the firewall entirely. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Could it be the case that hp-setup does not use avahi for the mdns discovery but sets up it's own listener on some random port instead? The firewall cannot catch that of course. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
