__FORCETOC__
<section begin=Body/>
Once the Embedded Device is finally configured for stand-alone bootstrap, the network interface should be configured for reaching the device remotely via network connections like ssh, telnet, ftp, http, etc.
This Application Note briefly describes how it is possible to simply configure the network interfaces on [https://en.wikipedia.org/wiki/UNIX_System_V SystemV] (aka ''SysV'') or [https://www.freedesktop.org/wiki/Software/systemd/ systemd]
=== Resources ===
The network configuration for systemd are basically found in the <code>/etc/systemd/network/</code> directory.
The most simply way for configuring the network interface is to create/edit the file '''/etc/systemd/network/20-eth0.network''' as per the following paragraphs.
For more example and usage hints on systemd, please refer to our [[XELK-AN-008:_How_to_use_systemd_on_an_Embedded_system#Configuring_the_network_interfaces | wiki]] page.

Address=192.168.1.100/24
Gateway=192.168.1.254
DNS=192.168.1.1
==== Apply configuration changes ====
After editing the above files, changes are applied after reboot or by restarting <code>systemd-networkd.service</code>and <code>systemd-resolved</code> services:
<pre class="workstation-terminal">
root@imx6qdlxelkdesk-mx6:~# systemctl restart systemd-networkd.serviceroot@desk-mx6:~# systemctl restart systemd-resolved
