Preface

Bloggers have been bothered by Bi Shi recently , It's been a week of dead and alive , Finally, the project failed , The virtual machine is playing like a thief .
blamed Torch, What's wrong with the installation , Come on, a fairy, take me ！！

People are already at a low ebb , How to walk is up . Although the main line still doesn't move , But I also learned a lot when pushing the main line , It's barely a loss . Gossip , Get into the subject .

Sometimes we need to transfer some files from the host to the virtual machine , Or you want to transfer the files of the virtual machine to the host . I don't know how the immortals of all parties solved it , Bloggers usually use Xshell And Xftp Software completed .
But if you want to use these two software , We still need to configure some things on the virtual machine first . The blogger sorted out the information on the Internet a little , Summed up this blog .

One . Check whether the service is on

Enter the command at the terminal ：

ps -e | grep ssh

If the display result is as shown in the figure below , Display in the interface sshd Service and ssh-agent service , So congratulations , You can try connecting virtual machines with software ：

But if you lack one of them , Not even one , Don't panic , Continue to look at .

---

Two . Turn on sshd service ( If enabled, skip this step )

Input in the terminal ( If you are not sure whether the virtual machine has installed this package , You can also enter the installation command , Does not affect the )：

sudo apt-get install openssh-server

After the installation is successful, you can enter ps -e | grep ssh see sshd Whether the service starts .
If there is still no , Continue to input... At the terminal ：

/etc/init.d/ssh start

Check again at this time ,sshd The service has been started successfully .

---

3、 ... and . Turn on ssh-agent service ( If enabled, skip this step )

Input in the terminal ：

eval 'ssh-agent'

---

Complete these three steps , We can try to use Xshell And Xftp The software is connected to the virtual machine .

But there are several problems that may arise next , Take it by yourself .

---

Four . Other problems that may arise

1. When entering a password, you can only enter public key

Then find this location , take PasswordAuthentication Change the following word to yes( It should have been no), And then restart sshd service ：

2.SSH The server denied access to the password

Remove the above reasons , There is another reason for this problem ： Use root The user login , So bloggers suggest not to use root user Log in .
