It's failing because the reverse hostname lookup failed. This might
indicate a DNS issue on your network. Does your DNS do PTR lookups?
For my system, as an example:
$ hostname
hardknott
$ hostname -f
hardknott.home.whinlatter.ukfsn.org
$ host -t A hardknott
hardknott.home.whinlatter.ukfsn.org has address 10.0.0.1
$ host -t PTR 10.0.0.1
1.0.0.10.in-addr.arpa domain name pointer hardknott.home.whinlatter.ukfsn.org.
Also test:
$ host -t A localhost
$ host -t PTR 127.0.0.1
and then repeat for the server. Can you post the results of all the
above here?
This may be also be related to this bug:
http://www.cups.org/str.php?L989+P0+S0+C0+I0+E0+Qrleigh
Could you try these three settings in cupsd.conf:
HostNameLookups On
HostNameLookups Off
HostNameLookups Double
These affect the CUPS name lookup behaviour. It does special case
localhost in some circumstances, which caused the above bug.
