This article introduces how to use the hostname command in Ubuntu, the content is very detailed, interested friends can use for reference, I hope it can be helpful to you.

Ubuntu network configuration is a common system, so I have studied Ubuntu network configuration. Here, I introduce the application of Ubuntu network configuration in detail. I hope that Ubuntu network configuration contains very good translation and easy-to-use architecture. Configure the DHCP address for the network card: if you want to configure the DHCP address, you need to edit / etc/network/interfaces and enter the following lines (assuming your network card is eth0): sudo vi / etc/network/interfaces

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

Auto eth0

Iface eth0 inet dhcp / / designated as dhcp

After entering these lines, you need to restart your network device with the following command: sudo / etc/init.d/networking restart

Configure static IP for network card

If you want to configure a static IP address, you need to edit / etc/network/interfaces and enter the following lines (assuming your network card is eth0): sudo vi / etc/network/interfaces

# The primary network interface

Auto eth0

Iface eth0 inet static / / designated as static

Address 192.168.3.90 / / IP address

Gateway 192.168.3.1 / Gateway

Netmask 255.255.255.0 / / Subnet Mask

Network 192.168.3.0 / / this. The Internet?

Broadcast 192.168.3.255 / / broadcast

After entering these lines, you need to restart your network device with the following command: sudo / etc/init.d/networking restart

Set a second IP address or virtual IP if you are a server administrator or just an ordinary user, and sometimes you need to assign a second IP to the system, you can do this and edit the / etc/network/interfaces file as well (assuming your network card is eth0):

Sudo vi / etc/network/interfaces 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

After entering these lines, you need to restart your network device with the following command: sudo / etc/init.d/networking restart

Set the hostname of the Ubuntu network configuration system to change the hostname of the system using the following command format, or edit / etc/hostname sudo hostname newname directly

Set up DNS

Sudo vi / etc/resolv.conf enter the following details search test.com nameserver 192.168.3.2 on how to use the hostname command in Ubuntu to share here, I hope the above content can be of some help to you, can learn more knowledge.
