I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04.
(Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it)
Edit: I've tried adding this to /etc/network/interfaces:
allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0
But this has no apparent effect, even after restarting NetworkManager.
Here's my /etc/NetworkManager/nm-system-settings.conf:
[main] plugins=ifupdown,keyfile [ifupdown] managed=false
Edit: Looks like I needed to restart nm-system-settings, then NetworkManager.
