      Hello All,

      I have to transition from Connman to Network Manager since Connman doesn’t connection isn’t connecting with the univeristy Eduroam. I’ve installed network-manager, network-manager-gnome and nm-tray. I wanna get the service started but I can’t find the service at all on /etc/init.d/. The nm-tray app simply says “NetworkManager is not running”. Could someone please help me start the network manager service? I am aware that before starting the service, I have to remove connman and cmst. Before I lose the internet connection, however, I wanna know exactly how to start the network manager service on the system.

      Here are the details of the system

      Dubito, ergo Cogito


          I saw this but I didn’t know the steps were the same for sysvinit as well. Thank you so much!!

          Dubito, ergo Cogito


            With sysvinit you need only add NetworkManager start to the /etc/rc.local file. You also need to edit connections via root nm-applet (gksu nm-applet).


              Thanks again for the input. I’ve got an issue that others have, namely, it connects to the AP but there is no name resolution. I’ve tried the symlink suggested in this post, namely

              1. Remove connman


              2. Delete the resolv.conf sym link in /etc/
              3. Create a new symlink in etc like this (in a terminal)

              sudo ln -s /etc/resolvconf/run/resolv.conf /etc/resolv.conf

              4. Try ceni again

              But that symlink hasn’t worked. I also tried the following symlink sudo ln -s /etc/resolvconf/resolv.conf /etc/resolv.conf

              I tried this since /etc/resolv/resolv.conf actally exists but this leads to a “Device not managed” dialog when nm-tray is selected.

              Do you have any suggestions?

                In my antix 23 runit

                sudo find / -iname "resolv.conf"
                [sudo] xxxxxxx-käyttäjän salasana: 

                You have a wrong path. ;)

                PS. I have not removed Connman, just commented out antiX network check in $HOME/.desktop-session/startup file.

                PS2. Remove connection from Connman before making a new connection via nm-applet.


                  Ah yes, there are three files. I have two questions.

                  1) Which file should I symlink with /etc/resolv.conf? My guess is `sudo ln -s /run/NetworkManager/resolv.conf /etc/resolv.conf’.

                  2) When you say remove connection from connman, is it enough if I delete the wifi_*** file(s) that connman has for different ssid(s) ?

                  I had to symlink with /run/resolvconf/resolv.conf. Thank you so much!!
