With Debian 9 and Debian 10 you must use the ip command to view the current state of your network interfaces. Verifying network settings in Debian 9 and Debian 10 To apply your new network settings you will need to bring the interface offline and then back online. iface enp0s3 inet dhcp Applying New Network Settings These values will automatically be assigned by your network. Unlike the the static IP address it’s a one-liner, as we do not need to set an address or gateway. Setting a DHCP AddressĪ DHCP address is configured as shown in the example below. For Debian 8 you would use the ifconfig command. For Debian 10 and Debian 9, you can use the ip a command. Verify your network settings are applied correctly. Bring the interface you just updated down.To apply your new network settings you will need to bring the interface down and then back up again. This configuration can be added to the interfaces file or written to a configuration file under /etc/network/interfaces.d.įor example, the file could be saved as /etc/network/interfaces.d/nf. gateway sets the network gateway IP address for routing traffic outside of the interface’s subnet.address sets the IP address to 192.168.1.2 and its subnet using CIDR /24, or subnet 255.255.255.0.The configuration above does the following: To set a static IP address for an interface named enp0s3, you would write the following configuration. ![]() It then proceeds to load network configurations from defined below that line. The first thing the interfaces file does it load additional configuration files from /etc/network/interfaces.d, if any files are stored there. # This file describes the network interfaces available on your system The /etc/networks/interfaces file looks like the following. The second location for network configurations is under /etc/networks/interfaces.d, where you can drop network config files rather than storing everything in the interfaces file. The primary location for network configurations is in the /etc/networks/interfaces file. This tutorial covers the following versions of Debian:ĭebian’s network interfaces can be configured in two places. You will also learn how to configure the DNS name servers, Gateways, and subnets. In this tutorial, you will learn how to configure network in Debian to use static IP addresses and DHCP.
