Specific issues
Name resolution
...
To avoid name resolution problems, it was sometimes necessary to copy to the legacy 127.0.1.1
entries to ::1
in the /etc/hosts
file:
Code Block |
---|
127.0.0.1 localhost
127.0.1.1 ldap.terena.org ldap
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback ldap.terena.org ldap
|
127.0.0.1
On IPv6 only hosts, there is no IPv4 address configured on the network interface, so obviously all communications will go via IPv6.
There is still an IPv4 address (127.0.0.1) sitting on the loopback interface lo
. It's doesn't hurt but it should not be there if the host were to be truly IPv6 only ![(wink)](/s/p416ui/8804/1v70iay/_/images/icons/emoticons/wink.svg)
I could not find anywhere in /etc
where this address get added.
Since I can prevent it from getting added, I removed it after it gets added, by hacking configuring /etc/network/interfaces
:
Code Block |
---|
# The loopback network interface
auto lo
iface lo inet6 loopback
pre-up ip addr del 127.0.0.1/8 dev lo
|
This seems to work fine, only now ntp dumps core, but that has been fixed as of 17 April 2011.
Skype
Skype does not support IPv6 at all. EPIC FAIL!!!! Please everybody VOTE FOR IPv6.
FYI the first request for IPv6 enabled Skype date back to 2004!!
