sudo apt install openssh-client
sudo apt install openssh-server

man sshd_config

  • To set your OpenSSH to listen on TCP port 2222 instead of the default TCP port 22, change the Port directive as such:
    Port 2222
  • To have sshd allow public key-based login credentials, simply add or modify the line:
    PubkeyAuthentication yes
    If the line is already present, then ensure it is not commented out.
  • To make your OpenSSH server display the contents of the /etc/ file as a pre-login banner, simply add or modify the line:
    Banner /etc/
    In the /etc/ssh/sshd_config file.

sudo systemctl restart sshd.service
