I'm trying to solve exactly this problem on a BeagleBoard via ssh, and can not use the GUI. On my laptop I moved at some point to NetworkManager, but decided not to use the GUI. I only use configuration files from /etc/NetworkManager/system-connections . $ cat /var/lib/NetworkManager/NetworkManager.state [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true Be sure to enable the parts you want enabled (wireless, wwan) here. I configure the wired network interface(s) in /etc/network/interfaces: allow-hotplug eth0 iface eth0 inet dhcp I also have some manual settings there. Then you need a configuration file. The name of the file can be arbitrary, but I name it the same as the name of the connection. $ cat /etc/NetworkManager/system-connections/example_wireless_plain [connection] type=802-11-wireless id=example_wireless_plain # You MUST set a different uuid for each connection.

Scanning is still more cumbersome, though. I never did get to autemate generating a config. Shouldn't be complicated, though.

Re: How do I disable NetworkManager in favor of dhcp setup?
I have nothing much against network manager, especially these days with wifi and wpa etc which is a mess to setup manually. On a laptop it's a lifesaver (although I always get into trouble when I try to manually set an IP address). It's just that with a server (or even a remotely accessed desktop), that has a single wired Ethernet connection, it's an overkill and causes problems if it requires actual local user logon before it has a network. And if it's a headless machine, that is not even an option. Anyways, thanks for the pointers, trying them out now. For some reason, the machine doesn't seem to actually reboot when I type reboot from the ssh terminal, but rather it just logs out, so it takes some time to get feedback (I need someone there physically to reboot).

No, it does not mean that at all. Simply set your eth0 connection to be a "system connection" to resolve your problem. On a wider note, I, too, used to hate Network Manager.

Re: How do I disable NetworkManager in favor of dhcp setup?
I've had luck with 'sudo telinit 6' in cases where the reboot command failed. There's also a /proc variable that will force a reboot when written to, but its name escapes me for the moment.

If you suspect a normal reboot won't work you might want to write there 's' (sync), 'u' (umount/mount readonly), then 'b' (boot).

How do I disable NetworkManager in favor of dhcp setup?
I have a redhat 6 desktop based system that exhibits a behavior where sshd fails to start on startup despite being enabled and requires manual startup after user login. I want to enable remote access before there is actual user login on the system I believe I pinpointed the problem tp NetworkManager being installed and enabled, which means that no network connection is actually configured before a user is logged in. I want to know how to remove NetworkManager and enable automatic network connection startup before sshd is started. /etc/network/interfaces doesn't exist, so I'm not sure how this is supposed to be achieved these days (under debian it's still there, just not active by default). It used to be possible to define the interface as auto dhcp in there to get the behavior I want. Will just adding that file do the trick is it supposed to be done differently?

On RedHat it's in /etc/sysconfig/network-scripts/ifcfg-interface-name, see 'man ifup' there.
