2011-10-31 | Our primary file server runs Samba on IPv6 only 
After the last Mac was upgraded to Lion I silently removed IPv4, and nobody even noticed  | Removed IPv4 address 192.87.30.132
Removed A record for samba.terena.org
Hardcoded the IPv6 address in smb.conf:
bind interfaces only = yes
interfaces = 2001:610:148:beef::132/64 | 2011-03-09 | All linux servers run PostgreSQL on IPv6 only | Configure "listen_address = '::'" in postgresql.conf. This is not documented (yet). | 2011-03-08 | HP Printer IPv6 only | Upgraded Laserjet 4250 with new print server, removed A record for hp4250-1.terena.org | 2011-02-28 | Host ldap.terena.org IPv6 only | Removed IPv4 address and 192.87.30.30

Samba
Our servers run Ubuntu 10.04 LTS, which ships with Samba 3.4.7, and this has proper IPv6 support. There is no global switch to make it listen to a specific IP version, but is not difficult to make it listen to IPV6 only.
You need to tell it to only bind to a specific (hard coded) interface address in smb.conf:
| Code Block |
|---|
bind interfaces only = yes
interfaces = 2001:610:148:beef::132/64
|
This machine is a server but sits in the Office network, so it was needed to disable autoconfiguration to prevent is from accumulating multiple IPv6 addresses (which is not good for a server).
Contrary to what you would expect, setting /proc/sys/net/ipv6/conf/eth0/autoconf to 0 does not do the trick. You have to explicitly state the interface. So I ended up with this /etc/network/interfaces:
| Code Block |
|---|
|
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet6 loopback
pre-up ip addr del 127.0.0.1/8 dev lo
# The primary network interface
auto eth0
iface eth0 inet6 static
address 2001:610:148:beef::132
netmask 64
gateway 2001:610:148:beef::1 dev eth0
pre-up echo 0 > /proc/sys/net/ipv6/conf/eth0/autoconf
