I have attached a program which demonstrates the bug. When you run this program you specify the host name to resolve as a command-line argument. The lines below show the relevant contents of my hosts file, and the output of the program when used with "localhost", "127.0.0.1", "localhost6", and "::1". It is only "localhost" which isn't working properly. I would have expected this to return the same result as "127.0.0.1" (in other words "::ffff:127.0.0.1") since my hosts file defines localhost as being 127.0.0.1. (Please note this behaviour is not specific to loopback addresses - I have used these in my example because they should be able to used to reproduce this fault on any machine.) nick@freddo:~/workspace/v4mappedtest$ grep localhost /etc/hosts 127.0.0.1 localhost.localdomain localhost ::1 freddo localhost6.localdomain6 localhost6 ::1 ip6-localhost ip6-loopback nick@freddo:~/workspace/v4mappedtest$ ./a.out localhost No address associated with hostname nick@freddo:~/workspace/v4mappedtest$ ./a.out 127.0.0.1 The following addresses were returned: ::ffff:127.0.0.1 nick@freddo:~/workspace/v4mappedtest$ ./a.out localhost6 The following addresses were returned: ::1 nick@freddo:~/workspace/v4mappedtest$ ./a.out ::1 The following addresses were returned: ::1 nick@freddo:~/workspace/v4mappedtest$ ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: libc6 2.13-0ubuntu13 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic i686 NonfreeKernelModules: nvidia Architecture: i386 Date: Fri Jun 3 22:17:20 2011 ProcEnviron: LANGUAGE=en_NZ:en PATH=(custom, user) LANG=en_NZ.UTF-8 SHELL=/bin/bash SourcePackage: eglibc UpgradeStatus: Upgraded to natty on 2011-04-29 (34 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/792300/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
