Today, I will talk to you about how to open SSH login in Ubuntu. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

0x00 Preface

After a new installation of ubuntu, the default is not to support ssh login. But ssh login we usually use. So install the SSH service.

The following is the installation process, if there is any objection, please correct me.

0x01 Install ssh

Here is the openssh series tool

Update system tools and dependencies, execute sudo apt-get update;

Execute the installation command sudo apt-get install opensh-server opensh-client and wait for the installation to complete.

0x02 Start ssh

Check to see if ssh is running and execute sudo ps -e| grep ssh, if nothing is displayed, is not running ssh service. Otherwise, the word sshd appears, indicating that the ssh service is running.

If ssh is not running, use the command sudo service ssh start.

#Start

/etc/init.d/ssh start

#Stop

/etc/init.d/ssh stop

#Restart

/etc/init.d/ssh restart

#Use the service command

#Start

``sudo service ssh start``

#Stop

``sudo service ssh stop``

#Restart

``sudo service ssh restart``

At this point,ssh is installed and running, and you can connect using the ssh client. But now it's disconnected.

SSh login will prompt SSh service refused to connect, how to break, please look down.

0x03 Modify configuration file

The requested URL/etc/ssh/sshd_config was not found on this server.

Open the configuration file with a name:gedit /etc/ssh/sshd_config;

Comment out the PermitRootLogin without out-password line in the configuration file;

Add a new line:PermitRootLogin yes;

Save configuration file and restart SSH service.

0x04 End

After doing the above operation, no other accidents, you can successfully log in to the host using ssh.
