HostNameLookups Double giving IP lookup failed - connection from localhost closed #4070
I have tried using this option (with a cupsd.conf that lists servers by name), but it it seems to break things (using the web interface).
First /var/log/cups/error.log fills up with:
W [30/Apr/2012:00:00:00 +0000] IP lookup failed - connection from localhost closed!
Even worse, some of the functions don't work. "Manage Jobs" just pulls up a blank page. "Manage Printers" says it is unable to get a list of printers. "Add Printer" says it is unable to add a printer.
I have tried various combinations of "localhost" and "localhost.example.com" with no difference in the outcome.
I believe I have the hosts file configured correctly.
Michael Sweet suggested "Feel free to file a bug requesting that we log the values we got to help with debugging these kinds of issues" so I am doing that.
