Hallo,

I can t find the switch to activate the network after an installation without gui. service network start doesn t work and I don t find any other commands.

Thanks for a hint.

Possibly during install you set the network connection but you didn't check the auto start check box, that is in the first label at the left of the network configuration page for that interface. If this is the case, if you are connected from console, and you defaulted to use NetworkManager (you can verify with "systemctl status NetworkManager"), these would be the commands:

You have devices and connections, that are different things; in my case an automatic install has created a device named ens192 and also a connection with the same name.

- device information [root@c7 ~]# nmcli dev status DEVICE TYPE STATE CONNECTION virbr0 bridge connected virbr0 ens192 ethernet connected ens192 lo loopback unmanaged -- virbr0-nic tun unmanaged -- [root@c7 ~]#

Last column gives connection name; one device could have many connections associated to it and you decide which is started in automatic for example

- connections information [root@c7 ~]# nmcli con show NAME UUID TYPE DEVICE ens192 9fb1de04-fda3-4db9-820e-d266e151ac73 802-3-ethernet ens192 virbr0 343ede6f-b7b0-4f73-a6f7-2bc9aee34d4a bridge virbr0 [root@c7 ~]#

- configuration of start type for the connection ens192 [root@c7 ~]# nmcli con show ens192 | grep -i connection.auto connection.autoconnect: yes connection.autoconnect-priority: 0 connection.autoconnect-slaves: -1 (default) [root@c7 ~]#

- set to auto if it is not so yet [root@c7 ~]# nmcli con mod ens192 autoconnect yes

- down and up [root@c7 ~]# nmcli con down ens192 [root@c7 ~]# nmcli con up ens192

- reboot to verify that autoconnects
