Virtual machine ubuntu networking steps.
Virtual machine is a technology that simulates the operating environment of multiple operating systems on a computer, among which Ubuntu is a popular Linux operating system. After installing Ubuntu using a virtual machine, network configuration is required to enable networking. Here are the steps to network a virtual machine ubuntu:
1.Open the virtual machine software and select the ubuntu virtual machine that has been installed.
2.Once you are in the Ubuntu system, open Terminal.
3.Run the following command to view the network interface information:
ip a This will display information about all network interfaces in the system, including the network interfaces of the virtual machine.
4.Configure the network interface. Assume that the network interface of the VM is eth0, and run the following command to enter the network interface configuration:
shellsudo nano /etc/network/interfaces
5.In the open file, find something similar to the following:
arduino
auto eth0
iface eth0 inet dhcp
This indicates that the eth0 interface uses DHCP to automatically obtain an IP address. If you need to manually configure an IP address, you can change DHCP to Static in iFace eth0 inet DHCP and add the corresponding IP address, subnet mask, gateway, and DNS server information. For example:
arduino
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8 8.8.4.4
6.Save and close the file. In the Nano editor, press "Ctrl + X" and then type "Y" to confirm the save.
7.Restart the network service. Enter the following command to restart the network service:
shellsudo service networking restart
8.Verify network connectivity. Run the following command to check whether the IP address of the network interface is correctly configured:
cssip a
If you see that the IP address of the eth0 interface has been configured correctly and you are able to access the Internet, it means that the virtual machine Ubuntu has been successfully connected to the Internet.
