• Logging into Development Environment
  • A. Using command-line
  • B. Using SSH config file

Welcome. Your first goal is to log into specified machine.

You will be given

• A username, e.g. YOUR_USER_NAME
• A .pem ssh-key, e.g. fcai-YOUR_USER_NAME.pem
• A hostname, e.g. 192.168.50.204

A. Using command-line

You are going to make your first manual attempt to connect, if anything is not working, please talk to us.

1. Make sure you have SSH installed in your local machine

   SSH client should be pre-installed on MacOS and most Linux distro, for Windows, use WSL2 to install a Linux distro.

    ssh -V
   
    #> OpenSSH_8.0p1, OpenSSL 1.1.1g FIPS  21 Apr 2020
    # Any version should work
   

2. Move ssh-key into ~/.ssh and set permission

    chmod 400 ~/.ssh/fcai-YOUR_USER_NAME.pem
   

3. Attempt to login using command line

    ssh -i ~/.ssh/fcai-YOUR_USER_NAME.pem YOUR_USER_NAME@192.168.50.204
   
    #> The authenticity of host '[192.168.50.204] ([192.168.50.204])' can't be established.
    #> ECDSA key fingerprint is SHA256:.....
    #> Are you sure you want to continue connecting (yes/no/[fingerprint])? 
   
    yes
   
    #> Warning: Permanently added '[192.168.50.204]' (ECDSA) to the list of known hosts.
    #> Last login: Mon May 23 06:55:19 2022 from 192.168.xxx.xxx
    #> [YOUR_USER_NAME@node4 ~]$ 
   

B. Using SSH config file

You can create an alias for this set of ssh login configuration using ssh config file

1. Edit your ~/.ssh/config

    Host fcai4
        HostName 192.168.50.204
        IdentityFile ~/.ssh/fcai-YOUR_USER_NAME.pem
        User YOUR_USER_NAME
   

2. Attempt to login using the alias

    ssh fcai4
   
    #> Last login: Mon May 23 06:55:19 2022 from 192.168.xxx.xxx
    #> [YOUR_USER_NAME@node4 ~]$
