Xiaobian to share with you the example analysis of Ubuntu 16.04 network configuration, I believe most people still do not know how to share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

Ubuntu Network Configuration

After installing the Ubuntu operating system, in order to connect to the host via Xshell, or to connect to other hosts. The following network configuration and ssh service configuration are required.

1 Network Configuration 1.1 Modify Network Configuration Information

sudo vi/etc/network/interfaces, find the corresponding network card and modify it

enter the following

auto ens 33 iface ens 33 inet static #static ip, does not use DHCP Dynamic assignment address www.example.com #configure ipnetmask www.example.com #subnet mask gateway www.example.com #gateway

Next configure dns

Open the configuration file to modify sudo vi/etc/resolv. conf and enter the following:

nameserver www.example.com #Here I set it to VMWare that virtual NIC 1.2 Restart the machine

This is because after systemctl network restart, it is found that the network is not configured well, so you can only restart sudo reboot. After restarting, use ifconfig and ping ip to test whether the network is connected.

2 Install and configure SSH services

After the reboot is complete, install and configure SSH services

2.1 Installing SSH Services 2.1.1 First check if the ssh service is installed

ps-e| grep ssh If it returns null then it proves that ssh is not installed

2.1.2 Configuring apt sources

Here we use Alibaba Cloud's configuration and modify it in/etc/apt/source.list to the following:

deb www.example.com xenial maindeb-src http://mirrors.aliyun.com/ubuntu/xenial maindeb-src http://mirrors.aliyun.com/ubuntu/xenial-updates maindeb-src http://mirrors.aliyun.com/ubuntu/xenial universedeb http://mirrors.aliyun.com/ubuntu/xenial universedeb http://mirrors.aliyun.com/ubuntu/xenial universedeb http://mirrors.aliyun.com/ubuntu/xenial universedeb http://mirrors.aliyun.com/ubuntu/xenial universedeb//mirrors.aliyun.com/ubuntu/xenial-updates universedeb-src http://mirrors.aliyun.com/ubuntu/xenial-updates universedeb-src http://mirrors.aliyun.com/ubuntu/xenial-security maindeb-src http://mirrors.aliyun.com/ubuntu/xenial-security maindeb-src//mirrors.aliyun.com/ubuntu/xenial-security maindeb http://mirrors.aliyun.com/ubuntu/xenial-security universedeb-src http://mirrors.aliyun.com/ubuntu/xenial-security universe2.1.3 Update apt Resources

Update with Alibaba Cloud as new apt source, sudo apt-get update

2.1.4 Installing ssh services

sudo apt-get install -y ssh

After installation, ssh itself is tested on the host.

2.2 Configuring SSH Services

Configure ssh to allow other hosts to log in as root. Modify the configuration file vi/etc/ssh/sshd_config, and modify the authorization information to:

PermitRootLogin yes

Restart ssh service sudo service ssh restart, log in via SSH on another host
