It is believed that many inexperienced people do not know what to do about how to configure the network card in DHCP mode in Ubuntu. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1. Configure the network card in DHCP mode

Edit the file / etc/network/interfaces:sudo vi / etc/network/interfaces

And replace the line about eth0 with the following line:

# The primary network interface-use DHCP to find our address

Auto eth0

Iface eth0 inet dhcp

Use the following command to make the network settings take effect: sudo / etc/init.d/networking restart can also enter the following command directly from the command line to get the address sudo dhclient eth0

two。 Configure a static IP address for the network card

Edit the file / etc/network/interfaces:sudo vi / etc/network/interfaces and replace the line about eth0 with the following line: # The primary network interface

Auto eth0 iface eth0 inet static address 192.168.3.90 gateway 192.168.3.1 netmask 255.255.255.0 # network 192.168.3.0 # broadcast 192.168.3.255

Change the above ip address and other information to yourself. Use the following command to make the network settings effective: sudo / etc/init.d/networking restart

3. Set the second IP address (virtual IP address)

Edit the file / etc/network/interfaces:sudo vi / etc/network/interfaces

Add the following line to the file:

Auto eth0:1 iface eth0:1 inet static address 192.168.1.60 netmask 255.255.255.0 network x.x.x.x broadcast x.x.x.x gateway x.x.x.x

Fill in all the information such as address,netmask,network,broadcast and gateways according to your situation. Use the following command to make the network settings effective: sudo / etc/init.d/networking restart

4. Set host name (hostname)

Use the following command to view the host name of the current host: sudo / bin/hostname uses the following command to set the host name of the current host: when the sudo / bin/hostname newname system starts, it reads the host name from / etc/hostname.

5. Configure DNS

First, you can add some host names and IP addresses corresponding to these host names in / etc/hosts, which is a simple native static query. To access the DNS server for query, you need to set up the / etc/resolv.conf file. Assuming that the IP address of the DNS server is 192.168.3.2, the content of the / etc/resolv.conf file should be:

Search test.com

Nameserver 192.168.3.2
