Where are the interfaces files?

[alexisfrjp]

I'm using Armbian 21.08.2 Focal with Linux 5.10.60-sunxi and I try to setup a bonding interface for failover between eth and wifi.

It doesn't seem to work after a reboot.

 

Where are all the interface's files? In RHEL it's under /etc/sysconfig/network, debian it's supposed to be /etc/network/interfaces but this last one contains only

 

source /etc/network/interfaces.d/*
# Network is managed by Network manager
auto lo
iface lo inet loopback

 

Thanks!

For NetworkManager, those files are in /etc/NetworkManager/system-connections.

 

For ifupdown, they are in /etc/network/interfaces and interfaces.d.

 

Both are available. I think NetworkManager is the upstream default.
