Linux system static Network configuration

After starting the Linux system, first look at the network configuration of the machine:

1, Ifconfig understand the network card information, view ETHX

2, sudo vim/etc/network/interfaces

Configure network parameters, such as:

Auto Lo

Iface Lo inet Loopback

Auto Eth0

Iface eth0 inet Static

Address (IP)

Netmask (Subnet mask)

Geteway (Gateway)

3, then configure Dns:sudo vim/etc/resolv.conf

4, restart the network formation: sudo/etc/init.d/networking restart

After reboot, if the Internet is not available, you need to add a gateway

5, sudo route add default GW

If you copy other virtual machines to use directly, there will be no Internet access, can not ping any IP address situation. This is because a direct copy of the virtual machine also copies its MAC address, causing it to be unusable in the new virtual machine.


1, delete/etc/udev/rules.d/70-persistent-net.rules

2, restart the virtual machine, the Linux system will automatically generate the file, and then configure the network will be able to access the Internet.
