If I set

	auto eth0
	iface eth0 inet6 manual
	# EOF

in /etc/network/interfaces, then network-manager seems to
ignore IPv4 on eth0, too. This is fatal.

I would suggest to keep IPv4 and IPv6 seperate, and to
introduce explicit "network_manager" methods for IPv4
and IPv6 in the interfaces file.


Please reassign, if necessary.

Are you using managed=true mode in /etc/NetworkManager/NetworkManager.conf?

It says:

	[main]
	plugins=ifupdown,keyfile

	[ifupdown]
	managed=false

AFAICS thats the default. If I set managed=true, then
eth0 gets both IPv4 and IPv6 addresses using DHCP4
and SLAAC. The "inet6 manual" in the interfaces file
is ignored.

Can you elaborate?

It's not clear what the problem is.

I would like to tell n-m to stay away from eth0 wrt IPv6.
The IPv6 configuration for this interface is done using
/sbin/ip in a script.

If I use the interfaces configuration as shown above,
then n-m doesn't set up eth0 for IPv4, either.

If I set "managed=true" and the same interfaces config
file, then n-m configures both IPv4 and IPv6.

The problem is that n-m either takes over or ignores the
whole eth0 interface without distinguishing between IPv4
and IPv6. I would like to restrict n-m to IPv4 for this
interface.

My suggestion is to introduce a "network_manager" method
for the "inet" and "inet6" address families in
/etc/network/interfaces, e.g.

	auto eth0
	iface eth0 inet network_manager
	iface eth0 inet6 manual
