Wouldn't running NM & ifupdown on the same interface cause potential conflicts? Why would you want both running?

According Debian wiki

NetworkManager does not manage any interface defined in /etc/network/interfaces by default.

If you want NetworkManager to handle interfaces that are enabled in

/etc/network/interfaces

Set

managed=true

/etc/NetworkManager/NetworkManager.conf

More details here:

Yes. That's what I would do.

NM is useless bloat with a vanilla ethernet connection. All it adds are bugs. IMO.

Thanks! So better using network via /etc/network/interfaces ?

EDIT: /etc/network/interfaces works via ifupdown & /etc/init.d/networking.

disable like that?

# The primary network interface
#auto eth0
#iface eth0 inet dhcp

Ok, thx for explain, i am try. But now my network works much stable(without NM) some times when i was using NM my networks is not works after boot. When i set network through /etc/network/interfaces i have no issues.
