The whole Kernel modules section is confusing. Is it mandatory? What exactly should we do?
As suggested by the Arch wiki, I used the
- HostNameLookups Double
option. However, that resulted in following error message: IP lookup failed - connection from localhost closed!
and I wasn't able to add printers via the CUPS web interface (internal server error)
It seems there is an outstanding bug with respect to the HostNameLookups: http://www.cups.org/str.php?L4070+Qversion:%20-feature
Removing the HostNameLookups double form the cups config file resolved my issue. Not sure why this used to solve instead of create problems.
