| Subject | How to disable dhclient to control the interfaces with NetworkManager? |
| Message-ID | <tj6sp-5OK-3@gated-at.bofh.it> |
Hello, I did install Debian GNU/Linux v8.7 through NetInstall option, during installation I did not select any Desktop Environment for install on system, only `standard utilities', after finish the installation, I did use `aptitude' to install xorg, gnome-shell, gnome-session and some parts of GNOME without recomended packages. Now anytime on system booting, dhclient automatically connects the interface to network and I just know to use `ifdown' by root user to turn off the interface. I want to disable dhclient to control the interface with NetworkManager by regular user. How is this possible? Sorry for my bad english; Thanks for help.

Dhcpclient should not be overriding NM. I don't have an NM installation to hand at the moment, but it is possible to edit the properties of any interface to connect automatically or not. Try left- or right-clicking the network icon and there should be an entry for configuration. It's a long time since I used it last. I recall having several fixed IP addresses that I wanted to switch a laptop between to troubleshoot a network, and any number of configurations can be created and called by name. All were set to manual connection. -- Joe

Edit /etc/network/interfaces and comment out the lines corresponding to your network interface, e.g. 'auto eth0', 'iface eth0 inet dhcp', etc. then restart NetworkManager (systemctl restart NetworkManager.service) -- Jonathan Dowland Please do not CC me, I am subscribed to the list.

So you have to make the decision how to manage your interface. By removing it from that file, NetworkManager takes over control again. However by default the NetworkManager also connects the interface if it is plugged in. It will try to assign the ip address through dhcp. If you do not want that you have to define a new profile and assign that to the interface. -H -- Henning Follmann | hfollmann@itcfollmann.com

That was my understanding of OP's desire: to have NetworkManager handle the interface, and do what it does. -- Jonathan Dowland Please do not CC me, I am subscribed to the list.
