Start dhcpd after network is enabled?

[aManFromOuterSpace]

hi,

Just a quicky.

How can I start dhcpd after Network manager has set up a new connected device.

The reason being that dhcpd will not start when there is nothing connected to the network interface. Therefore I would like dhcpd to start after a new device is connected.

Now i have found references if ifup-post but this does not relate to NM, is this correct?

Thanks

I assume that you are running a server

Why would you depend on nm in this case?

Just use text config files don't depend on gui

I believe that nm has a service though

I have dhcpd set to run as a service but dhcpd fails to start when there aren't any network devices attached.

I did come across a post that said that I could run dhcpd as a daemon, so I could probably drop the following into rc.d or something like that

dhcpd -d -f eth0 &

I am obviously relatively new to Linux, I would like to get away from using Gnome apps for configuring all the various aspects of my system. If I were to uninstall NM what would be the alternative for controlling network devices?

Update: dhcpd -d -f eth0 & is giving the same problem.

It seems that it is only possible to run dhcpd when there is something connected to the interface, I would have thought it would have been able to listen until something is attached to the server.

I'll add my dhcpd.conf just in case, even though it works ok when eth0 is connected to a network.

i don't know what your distro is, so i can't really tell you how to set up your network without networkmanager

I managed to get the result I require with a little help from the fedora irc channel. I had to disable NM and use network. Also the line NM_CONTROLLED had to be added to network config script. This resulted in my network interfaces being brought up on boot even when there was nothing connected to either ethernet port on my server, this then allowed dhcpd to start.

Thanks for the input.
