Records of using ssh commands on Windows 8

1. Open the virtual machine and git bash window and prepare to connect

2. Enter ifconfig -a in the virtual machine to view the virtual machine IP

Find the IP address from the picture: inet address: 192.168.78.133

3. Enter the command: ssh [email protected] -p 22 to connect to the virtual machine

At this time, my computer reported an error: ssh: connect to host 192.168.78.133 port 22: Connection refused

This error may be caused by ssh-server not being installed or not being started. Ubuntu 11.10 installs openssh-client by default, but does not install server

Run ps -e | grep ssh to check whether there is an sshd process.

If not, it means the server is not started. Start the server process through /etc/init.d/ssh -start . If it prompts that ssh does not exist, then the server is not installed.

sudo apt-get install openssh-server

4. After installation, start the server service

5. At this time, use ssh [email protected] -p 22 to connect to the virtual machine again.

However, I did not set a password and do not know the password, so using the virtual machine password is useless.

At this point we can only modify the ssh configuration file to modify

Change PermitRootLogin prohibit-password in the /etc/ssh/sshd_config file PermitRootLogin yes (or delete PermitRootLogin prohibit-password. For safety, you can back it up and comment it out.)

View file permissions when modifying

At this point, you can see that the file has been changed to a normal file with permissions of rw-r--r--

To modify the file we can change the file to rwxrwxrwx

Execute the command: sudo chmod 777 /etc/ssh/sshd_config

Check permissions again

Use vim to modify the configuration: vim /etc/ssh/sshd_config

After modification, change the permissions back: sudo chmod 644/etc/ssh/sshd_config

sudo /etc/init.d/ssh restart restart

At this point, the password has been changed to the root user's password, but we still don't know the password

The default root password of Ubuntu is random, that is, there is a new root password every time you boot the computer. We can enter the command sudo passwd in the terminal, then enter the current user's password, enter,

The terminal will prompt us to enter a new password and confirm it. The password at this time is the new root password. After the modification is successful, enter the command su root and then enter the new password.

There is no default analysis because you haven't set a password for root. The first user is in the admin group, so he can set a password for root, so
sudo passwd root
[sudo] password for you: ---> Enter your password, it will not be displayed

Enter new UNIX password:

--- > Set root password
Retype new UNIX password:

Now just log in using the password you set.

Login successful, everything is ok
