Here is my view of the problem: On an up-to-date Maverick install, if /etc/hosts looks like the following on bootup...
-------- 127.0.0.1 localhost 127.0.1.1 hostname.intra.example.com hostname # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters -------- ...NetworkManager changes it (syslog: "<info> Updating /etc/hosts with new system hostname") to this: -------- 127.0.0.1 hostname localhost.localdomain localhost ::1 hostname localhost6.localdomain6 localhost6 127.0.1.1 hostname.intra.example.com hostname # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters -------- With that, "hostname -f" incorrectly returns just the unqualified hostname. I think part of the problem is the layout convention being used for /etc/hosts. The first example above was the result of the Ubuntu alternate installer. On a different system installed with Ubiquity, however, I have this (note that this system does not have a domain part, so I can't tell if "hostname -f" is broken or not): -------- 192.168.1.XX hostname # Added by NetworkManager 127.0.0.1 localhost.localdomain localhost ::1 hostname localhost6.localdomain6 localhost6 127.0.1.1 hostname # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts -------- I think N-M's logic for modifying /etc/hosts may not be robust enough to generate a correct file given some of these inputs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/8980 Title: hostname -f does not return a proper FQDN -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
