Setting up remote access to your Ubuntu system

Introduction

The Ubuntu system is one of the Linux systems commonly used by enterprises and individuals. Due to its good graphics support and good development tool support, programmers prefer the Ubuntu series system. Recently, I helped a friend's company solve a problem and used a virtual machine to create an Ubuntu test environment. I found that Ubuntu's default security level and remote tools were not set. Next we will install the ssh service and then enable root permissions (not recommended)

System environment

Our system uses the virtual machine vmware workstations 12 version Ubuntu17.04 for experiments:

Install ssh service Check network connectivity

Upgrade the installation source (required for first time use)

Install ssh service

Start ssh service

Check the ssh service startup status

Set up the ssh service to start at boot Try to use chkconfig to set up ssh startup

systemctl Sets the ssh service to start at boot

Modify the ssh configuration file and enable root user login View IP and try to log in remotely

ok, ordinary user login successfully. Let's try switching to root.

Switch to normal user

Change root password

Try to log in to the system as root user

Modify the ssh configuration file and enable root login

Use root user for root login
