Since recent, i cannot connect anymore to localhost:631 (the cups administration server). Printing does not work too, obviously ...
I had a working set-up and, as suggested in the infos i protected the following files:
/usr/local/etc/cups/ppd/HP_DESKJET_3900.ppd
/usr/local/etc/cups/printers.conf
/usr/local/etc/cups/cupsd.conf
I looked into cupsd.conf, but art a 1st glance all seems set well (webinterface = yes, listen = localhost:631, administration "user @OWNER @SYSTEM") ...
I also tried with firefox started by root, but i did not change anything.
Any ideas?
