* IP address of the device '''192.168.1.100'''
=== SysV systemd ===
The network configuration files for SysV can be systemd are basically found in pre-defined directorys as written [https:the <code>/etc/en.wikibooks.orgsystemd/wikinetwork/Linux_Networking</Where_should_I_put_the_configuration_commands%3F here]code> directory.
Basically, The most simply way for configuring the network configuration, it should be enough interface is to properly configure create/edit the <code>file '''/etc/systemd/network/interfaces<20-eth0.network''' as per the following paragraphs. In the event that there are another network interface, then this must be create/code> file. # edit as '''/etc/systemd/network/interfaces 20-- configuration file for ifup(8), ifdown(8)eth1.network'''. Here below an For more example of configuration fileand 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.
==== Static IP address ====
The SBC ORCA has two network interface interfaces, below is configured with shown how to configure them both through a static IP address by creating the configuration entry in the '''/etc/network/interfaces''' file as the following:.
Example for ethernet interface 0.
<pre>
auto eth0[Match]iface Name=eth0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.254</pre>
# Prevent the interface loading if the kernel boots from nfsKernelCommandLine==== Dynamic IP addres (DHCP) ====!nfsroot
The network interface is configured - using a proper DHCP server on the network - by creating the configuration entry in the '''/etc/network/interfaces''' file as the following:[Network]Address=192.168.1.100<pre>Gateway=192.168.1.254allow-hotplug eth0iface eth0 inet dhcpDNS=192.168.1.1
</pre>
When the Linux kernel detects the physical Example for ethernet interface eth0, the iface causes ''ifup'' to use DHCP to configure the interface. ==== DNS ==== If the <code>resolvconf</code> package is not installed, the DNS configuration can be done manually by editing the '''/etc/resolv1.conf''' as the following:
<pre>
nameserver 192.168.1.1[Match]</pre>Name=eth1
For example, it can be done on # Prevent the command line echoing interface loading if the string in this way:kernel boots from nfsKernelCommandLine=!nfsroot
root@axel-lite:~# echo "nameserver [Network]Address=192.168.1.101Gateway=192.168.1" > /etc/resolv.conf254DNS==== loopback network interface ==== The following configuration entry in the '''/etc/network/interfaces''' file brings up the loopback network interface lo upon booting the system192.168.1.<pre># The loopback interfaceauto loiface lo inet loopback1
</pre>
This one always exists in Once modified, the ''<code>networkd</etc/network/interfaces'' file.code> service should be resarted:
=== systemctl restart systemd ===-networkd
The network configuration for systemd are basically found in the <code>/etc/systemd/network/</code> directory.==== Dynamic IP addres (DHCP) ====
The most simply way for configuring the network interface is to create/edit configured - using a proper DHCP server on the network - by using the file '''/etc/systemd/network/20-eth0.networkDHCP''' key in the configuration file 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. ==== Static IP address ====
<pre>
[Network]
AddressDHCP=192.168.1.100Gateway=192.168.1.254DNS=192.168.1.1yes
</pre>
Once modified, In the <code>networkd</code> service should be resarted: systemctl restart systemd-networkd ==== Dynamic IP addres (DHCP) ==== The event that there are another network interface is configured - using a proper DHCP server on the network - by using the '''DHCP''' key in , the configuration file as the following:
<pre>
[Match]
Name=eth0eth1
# Prevent the interface loading if the kernel boots from nfs
==== Apply configuration changes ====
After editing the above files, changes are applied after reboot or by restarting <code>systemd-networkd.service</code>:<syntaxhighlight lang="bash">
root@imx6qdlxelkdesk-mx8mp:~# systemctl restart systemd-networkd.service
</syntaxhighlight>
