From almost any Linux system you can use "ip" or the ifconfig/route commands to initially set up the network.
# Bring up the CPU network interface
ifconfig eth0 up
# Or if you're on a baseboard with a second ethernet port, you can use that as:
ifconfig eth1 up
# Set an ip address (assumes 255.255.255.0 subnet mask)
ifconfig eth0 192.168.0.50
# Set a specific subnet
ifconfig eth0 192.168.0.50 netmask 255.255.0.0
# Configure your route. This is the server that provides your internet connection.
route add default gw 192.168.0.1
# Edit /etc/resolv.conf for your DNS server
echo "nameserver 192.168.0.1" > /etc/resolv.conf
Most commonly networks will offer DHCP which can be set up with one command:
Configure DHCP in Debian:
# To setup the default CPU ethernet port
dhclient eth0
# Or if you're on a baseboard with a second ethernet port, you can use that as:
dhclient eth1
# You can configure all ethernet ports for a dhcp response with
dhclient
To make this set up the network so that it sticks between boots, you will need to configure systemd's networking:
In /etc/systemd/network/eth.network
[Match]
Name=eth*
[Network]
DHCP=yes
Then, if you intend to use DHCP to configure your DNS, start and enable the network name resolver service:
systemctl start systemd-resolved.service
systemctl enable systemd-resolved.service
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
For a static configuration you would create a config file for that specific interface. /etc/systemd/network/eth0.network
[Match]
Name=eth0
[Network]
Address=192.168.0.50/24
Gateway=192.168.0.1
DNS=192.168.0.1
