Hi,

I am quite new in gentoo and just installed gnome/systemd.
I emerged NetworkManager.service and at the moment it is working in dhcp mode -
I prefer to switch to static IP - I do know how to do it in OpenRC but need your advise regarding systemd.

Marlo Hi,

As I noted in my post I am new in gentoo...

I understand that I should change to my network name card and to my IP address but -
please explain me what I should do with this text?

I enabled NetworkManager.service - Static IP is not part of it?

Thanks

Might be a little late but better late then never.
First I don't know wether you could set-up a static network with networkmanager.
But it would be strange if it couldn't be done.

If you want the network always be the same then you do not have the need fore networkmanager.
You can then open a terminal and type this:

You should be able to set it up with nm-applet under gnome
settings => network => wired then click on the gear * bottom right => ipv4 => Addresses => Manual

Dear elmar283 & comprookie2000,

If you might want to try an network on systemd without NetworkManager, I just figured that out yesterday:

I have used the above Unit on several computers for a long while with no problems. Recently, however, after a fresh gentoo installation, it has failed to work: --on the new setup only, it continues to function on two other machines.

After booting, "systemctl status static-network.service" produces the following:-

"Loaded: loaded( /etc/systemd/system/static-network.service; enabled; vendor preset; disabled)"

If I 'restart' the unit it sets up my network as I intended. I do not understand the significance of 'vendor preset' , and would be grateful for an explanation. It is apparent that the unit is loading, but failing to act, so presumably something is missing, but I cannot fathom what that could be.

I am using kernel-4.9.16-gentoo

just.. cool kernel parameters you could try:

ip=${my_ip}:${router_ip}:${nfs_root_ip_not_that_it_matters}:${netmask}:${hostname}:${interface}:${dns1}:${dns2}

ip=192.168.23.23:192.168.0.1:192.168.0.2:255.255.0.0:somehost:eth0:8.8.8.8:8.8.4.4

did you know your kernel does that?

I tried axl's suggestion but it didn't work. I think because eth0 is changed to enps07 later in the booting process. Also, my ethernet card is started by a module, which dmesg shows as not starting until near the end of the boot process.

It was all so simple before systemd came along. Just two lines of code would do!

I use systemd-networkd on my systemd PC.
The documentation on the wiki is poor a the moment.
This is what I have:

Thanks Zucca. Your contribution made me aware that there is a man page for systemd networking! I think now that I have a better understanding of systemd's intentions concerning ethernet configuration! I don't think this procedure or a manual was available when I first swapped to systemd.

Anyway I have set up a *.network file in "/etc/systemd/network" similar to yours, enabled systemd-networkd.service and all is now working as I intended.

elmar283 and Mario's steps did not work for me until I added the following three steps:

1. Change resolve.conf into a standard file instead of a shortcut file in /etc.

2. Remove (un-emerge) BOTH dhcp & dhcpcd. Because I removed dhcp & dhcpcd completely, if my new Internet connection did not work I would have no Internet connection to download dhcp & dhcpcd to get my ORIGINAL dhcp Internet connection back. So DO MAKE SURE as an insurance policy, and BEFORE you remove dhcp & dhcpcd, to have the latest copies of dhcp & dhcpcd in /usr/portage /distfiles in order to re-emerge them without needing the Internet. Of course this is only necessary if your static connection did not work in order to revert to the old dhcp connection.

At the first when I had everything configured I issued the following commands:
