--> Describe the problem

I don't want to enter a password and such a long command every time I login to the SSH server. What should I do?

--> Demonstrate the solution

What you should do is add a config file to save the SSH information. The steps are detailed demonstrated below:

• Create a new file named config in your local .ssh folder

  $ cd ~/.ssh
  $ touch config

• Edit the config file with the following template

  $ vim config

  Template

  Host lab
  HostName <server's IP address>
  Port <Server's ssh port (22 default)>
  User root
  IdentitiesOnly yes
  IdentityFile ~/.ssh/id_rsa

• Copy your public key to the remote server's ~/.ssh/authorized_keys

  $ vim ~/.ssh/authorized_keys

• Using

  $ ssh lab

--> Additional context

Now you can connect to your ssh server without password, and also it's available when using the scp command.
