Our primary file server runs Samba on IPv6 only (smile)
After the last Mac was upgraded to Lion I silently removed IPv4, and nobody even noticed (tongue)

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

All linux servers run PostgreSQL on IPv6 only

Configure "listen_address = '::'" in postgresql.conf. This is not documented (yet).

HP Printer IPv6 only (smile)

Upgraded Laserjet 4250 with new print server, removed A record for hp4250-1.terena.org

Host ldap.terena.org IPv6 only (smile)

Removed IPv4 address and 192.87.30.30
Removed A record

Host svn.terena.org IPv6 only (smile)

Removed IPv4 address and A record

2011-02-01

All linux servers run Postfix on IPv6 only (except listed MXs)

Remove IPv4 addresses from $mynetworks, and set "inet_protocols = ipv6"

2011-01-31

All linux servers managed by SSH via IPv6 only

Configure "ListenAddress ::" or "AddressFamily inet6" in sshd_config

2011-01-30

All linux servers use only IPv6 resolvers

Only list IPv6 addresses in /etc/resolv.conf:

No Format
nameserver 2001:610:148:dead::4
nameserver 2001:610:158:98d::42
domain terena.org

VPN supports IPv6

A new VPN setup: Cisco AnyConnect. Clients get an IPv4 and an IPv6 address from the office pools, so they can access all services via IPv6

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
bash
bash

# 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
