Setup a static IP address - systemd

Setup a static IP address - systemd

[Konstantin Kletschke]

Dear yocto, community,

I have a yocto build running on a Beaglebone Black with systemd enabled.
No /etc/init.d, no /etc/network/interfaces.

How do I set up a static IP Address for eth0?
The system always does an udhcpc request and uses that.

I have 
systemd-networkd.service loaded active running 
and tryed the following file in /etc/systemd/network:

# cat eth0.network
[Match]
Name=eth0

[Network]
Address=10.2.3.4/24
Gateway=10.2.3.1
DNS=1.1.1.1


Kind Regards
Konstantin

I think you're having a higher priority configuration file taking effect.
Check /lib/systemd/network and /run/systemd/network.
Maybe renaming your configuration file to 00-eth0.network would solve the problem.

Yes indeed. I am searching the web for ages for this, my colleauge also
found out within a couple of minutes :-|

Renaming the file having an additional prefix like "10-" works like a charme.
I suspect the number has to be lower than the 80 found in many files in
/lib/systemd/network...

Thanks for your provided solution, many thanks!

Kind Regards
Konstantin
