Install SSH service
There is no SSH service installed in Ubuntu by default. If you connect to Ubuntu via SSH, you need to manually install sSH-Server yourself. To determine whether to install SSH service, the following command can be used:

    : [email protected]:~$SSH localhost SSH: connect to host localhost port 22: Connection destination: Connection union

 
As shown above, it means that it has not been installed yet. It can be installed through APT. The command is as follows:

    : [email protected]:~$sudo apt-get install openssh-server

 
The system will be installed automatically. After the installation is completed, the service will be started first:

    [email protected]:~$sudo/etc/init. D/SSH start
     
    After startup, you can check to see if the service started correctly with the following command
    Ps

      [email protected]:~$- e | grep SSH 6212?00:00:00 SSHD
       
      As indicated above, start OK. Note that the default port for SSH is 22. You can change the port, stop,
      and then start. The configuration is under /etc/ssh/sshd_config, as shown below.

        [email protected]:~$vi /etc/ SSH /sshd_config # Package generated configuration file # See the SSHD (8) manpage for details # What ports, IPs and protocols we listen for Port 22
         
        Finally, it’s time to connect. See the following command:
        SSH [email protected]

          [email protected]:~$
          Disconnect:
          The

            exit
             
            Log into the virtual machine via Putty
            First of all, make sure that the virtual machine and host can ping each other. If you can’t ping the general, then the follow-up work cannot be carried out. You can search the Web for references to articles on VIRTUAL machine IP configuration
            Next, open the Putty client and the following interface appears. Fill in the relevant parameters:

            Where the IP address is the IP address of Ubuntu in the virtual machine.
