Generating SSH keypair

Windows

• Go to this site https://8gwifi.org/sshfunctions.jsp
• For passphrase enter a password (you need to remember this)
• Choose RSA key size 1024
• Click Generate SSH keys
• You can either email the keys to yourself
• or copy paste the private key and save it to a file on your computer, same with public key
• In the end you should have one file containing the private key and one file containing the public key (make sure you save them in a safe spot)

Linux and mac

• use command ssh-keygen and follow instructions
• https://docs.oracle.com/cd/E19683-01/806-4078/6jd6cjru7/index.html
• run ls ~/.ssh/ you should see id_rsa.pub key there

Adding public key to server

• Provide your public key (id_rsa.pub) to the person who has ssh access to the server ( we'll call this person admin)

• Ask admin to run the following commands

  scp [path to id_rsa.pub] [email protected]:/tmp/id_rsa.pub

  scp transfers the id_rsa.pub on admin's local machine to the desired server

  ssh [email protected]

  cat /tmp/id_rsa.pub >> ~/.ssh/authorized_keys

  >> appends the contents of /tmp/id_rsa.pub to ~/.ssh/authorized_keys.

  If you overwrite this file no one will have access to the server, so be careful.
