How-to

Generate a pair of key

text
ssh-keygen -t rsa

make sure the generated file located on ~/.ssh

text
ssh-copy-id -i ~/.ssh/id_rsa.pub username@ip-addr

make sure you've enable PubkeyAuthentication on the /etc/ssh/sshd_config file

optionally, you can disable PasswordAuthentication if you are pretty sure to not login from other non-authorized device

Bonus

Make the login process more easier by just typing ssh serper.

edit file ~/.ssh/config and append the following section:

text
Host serper
  HostName ip-addr
  User username
  Port 22
  IdentityFile ~/.ssh/id_rsa

  • ssh(1)
