NetworkManager supports the IPv6 protocol and it is turned on by default. It connects to networks with SLAAC and DHCPv6 and keeps the connection running. Many bugs have been fixed recently, so it's possible that it doesn't work well in your distribution. Reasonably good support will be delivered with NetworkManager 9.6 and Linux 3.5.
Due to the existence of IPv6 link-local addresses, routing configuration and address configuration are orthogonal.
Please remember that IPv6 is different.
For details about possible IPv6 scenarios, see Networking/Addressing#Dynamic_IPv6_configuration.
IPv6 Privacy Extensions
NetworkManager supports privacy extensions through the 'ip6-privacy' key.
An example of a minimally configured keyfile (placed in /etc/NetworkManager/system-connections) is below. Values for the connection section may be obtained using the
nmcli connection command.
[connection] id= uuid= type= [ipv6] method=auto ip6-privacy=2
Or edit a gui created config file at /etc/sysconfig/network-scripts/ifcfg-* and add
You can run NetworkManager on foreground with various debugging settings:
/path/to/NetworkManager --no-daemon \ --log-level=debug --log-domains=DEVICE,IP6,DHCP6 2>~/nm.debug
Be careful not to run multiple instances of NetworkManager. Check with
ps -ef if you experience weird behavior.
- Don't tear down interfaces, keep link-local networking always on
- Get kernel problems fixed, then simplify ipv6 handling in NM
