Step 6: Now open the network interface file by running the below command. ~#] sudo grub-mkconfig -o /boot/grub/grub.cfgįound background image: /usr/share/images/desktop-base/desktop-grub.pngįound linux image: /boot/vmlinuz-5.10.0-16-amd64įound initrd image: /boot/initrd.img-5.10.0-16-amd64 Step 5: Next regenerate grub configuration file by using the below command. GRUB_CMDLINE_LINUX=" net.ifnames=0 biosdevname=0" Its primary use is to set up static routes to specific hosts or networks via an interface after it has been configured with the ifconfig (8) program. But we will see how we can install and fix ifconfig in our Debian 12. However, itâs recommended to use the modern ip command for networking tasks. Step 4: In order to change Network Interface name, we require to edit grub configuration file by using the below commands. To use ifconfig in Debian 12, you can install the net-tools package, which includes the ifconfig command. Restart networking service and obtain a new IP address via DHCP on Ubuntu/Debian Linux. Force Linux to renew IP address using a DHCP for eth0 interface. pcnet32: eth0: registered as PCnet/PCI II 79C970A Find the current ip address for the eth0 interface in Linux. Step 3: Debian has it network interface name as eth0 while in boot time it will automatically renamed to ens33 to verify this using the below command. TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 You will get a list of all private IP addresses on this. In my example, the network interface is ens33. Replace with the interface that you like to look up.RX errors 19 dropped 0 overruns 0 frame 0 If you want to check the network configuration for a particular interface, the command should look like the following. Step 2: Verify your network interface name using âifconfigâ command or âip aâ command. Step 1: Check the OS Version by using the below command ~#] lsb_release -aÄescription:Äebian GNU/Linux 11 (bullseye) It is quite easy to change the Network Interface name on your Debian machine and this article can help you with that. Once Debian 11.3 is installed, the network interface name gets changed from eth0 to ens33. The network interface name depends on the Ethernet connections available and its number should vary from eth0 to eth1. Generally, a Network interface is named either eth0, eth1, eth2 and etc. This package integrates all the old tools that we have. Installing the old suite of ifconfig and route networking tools is really simple, the first thing we have to do is open a terminal, log in in root mode or use the sudo command, and install a package called net-tools. To Change Network Interface Name on Debian 11.3 Introduction: Ifconfig and route installation on Debian 9 or higher.
