I've installed cups and cups-client.
I'm in the lpadmin group.
Now when I click on 'Add Printer' in the Administration nothing happens.
The access log says it was successful though.
localhost - - [11/May/2012:13:43:49 +0200] "POST /admin/ HTTP/1.0" 200 60 - - localhost - - [11/May/2012:13:43:49 +0200] "POST /admin/ HTTP/1.0" 200 4987 - -
EDIT: it does not work with localhost:631 or 127.0.0.1:631 but with the ipv6 version http://[::1]:631
EDIT2: contents of
127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
EDIT3: changed the first line of the /etc/hosts to 127.0.0.1 localhost ipv4-localhost ipv4-loopback, still don't working. if I bind cups to 127.0.0.1 it is obviously not reachable via [::1]:631 but still not working via 127.0.0.1/localhost either.
