Description Thomas Meyer 2011-02-25 19:35:48 UTC 
Description of problem:
Before Fedora 15 I could do this on the command line (no GDM or X server started)

1.) stop the NetworkManger service
2.) iwconfig the wireless device
3.) dhclient wlan0

This way I got a running network device on a non X server environment.

This doesn't work anymore in Fedora 15. When I do:

1.) systemctl stop NetworkManager.service
2.) iwconfig the wireless device
3.) dhclient wlan0

the dhclient call seems somehow start the NetworkManager. The NetworkManger takes over the wlan0 and my manual configuration is gone.

I needed to remove the NetworkManger.service file from /lib/systemd/system, to get a working network.

This is mostly like fixed by recent changes to NM which make sure that nmctl does not trigger a NM startup, when it is called from the network scripts.


BTW, if you want to completely disable a service, you can "mask" it by symlinking /dev/null to it in /etc. Example: "ln -sf /dev/null /etc/systemd/system/NetworkManager.service".

I presume this is fixed in current F15. If not, reopen!
