• If you was first time log into the remote server, you will something like this:
  ssh cs15lfa22zz@ieng6.ucsd.edu
  The authenticity of host ‘ieng6.ucsd.edu (128.54.70.227)’ can’t be established. RSA key fingerprint is SHA256:ksruYwhnYH+sySHnHAtLUHngrPEyZTDl/1x99wUQcec. Are you sure you want to continue connecting (yes/no/[fingerprint])?

  class WhereAmI {
  public static void main(String[] args) {
  System.out.println(System.getProperty(“os.name”)); System.out.println(System.getProperty(“user.name”)); System.out.println(System.getProperty(“user.home”)); System.out.println(System.getProperty(“user.dir”));
  }
  }
• In your terminal, if you did not log out from remote server, you can type the exit to log out first. Then type:

• After you log off from remote server you have to use scp to upload your public key in order to make the key work. Format:
  scp (/Users/joe/.ssh/id_rsa.pub)–>(change to your public key file location) (cs15lfa22@ieng6.ucsd.edu) –> (change to your account number):~/.ssh/authorized_keys
• After you done with all those step, congratulation you can log in without using the password. — Step 6 Optimizing Remote Running —
• Right now you done with ssh-key, you can try something that can save less time to type other stuff like:
  ssh (cs15lfa22) –> (change to your account name)@ieng6.ucsd.edu “ls”
