[Bug 285132] [NEW] Apache2 has trouble handling (ip6-)localhost

[Andreas Olsson]

Public bug reported:

Binary package hint: apache2

This problem is related to running Apache2 in Intrepid.

At my workstation at home I like to tell Apache to "Listen localhost:80"
(This I do in ports.conf)

In Intrepid that results in the following error

root at hawat:~# /etc/init.d/apache2 restart
 * Restarting web server apache2                                                                                                      
... waiting (98)Address already in use: make_sock: could not bind to address 127.0.0.1:80
no listening sockets available, shutting down
Unable to open logs

This error don't happen if I instead use "Listen 127.0.0.1:80".

It seems as if Apache's problems are related to how the default
/etc/hosts in Intrepid defines ::1

In Hardy /etc/hosts says
::1     ip6-localhost ip6-loopback

In Intrepid it is instead
::1     localhost ip6-localhost ip6-loopback

If I change my /etc/hosts back to Hardy-style  (::1     ip6-localhost ip6-loopback) I can use "Listen localhost:80" in Apache 
without any problems.
