Debian 11 NetworkManager not recognizing static IP configuration in /etc/network/interfaces
I'm testing a new approach and Quick question that's been bugging me - Hey everyone, I'm running into an issue that's driving me crazy. I'm working with an scenario where my static IP configuration in `/etc/network/interfaces` is being ignored by NetworkManager on Debian 11. I have the following configuration: ```bash # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 iface eth0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 ``` However, after a reboot or restarting the network service, I find that my `eth0` interface is being assigned a DHCP IP instead. I've tried disabling NetworkManager for the interface by adding `managed=false` in `/etc/NetworkManager/NetworkManager.conf`, but it doesn't seem to have any effect. Here's the relevant part of my config: ```ini [main] disabled=true [ifupdown] managed=false ``` I've restarted the NetworkManager service each time after making changes: ```bash sudo systemctl restart NetworkManager ``` Despite this, NetworkManager still seems to take control over the `eth0` interface. Any insights on how to make NetworkManager respect my static IP configuration, or should I be configuring the static IP in NetworkManager instead? Also, what logs should I check to troubleshoot further? Thank you! My development environment is macOS. What's the best practice here? Any help would be greatly appreciated! I'm working in a Windows 10 environment.
