  1. \nConnect to the server via SSH<\/a>;\n<\/li>
  2. \nCreate the key pair\n<\/li><\/ol>\n\n\n\n

    ssh-keygen -t ecdsa -b 256<\/p>\n\n\n\n

    Generating public\/private ecdsa key pair.
    Enter file in which to save the key (\/root\/.ssh\/id_ecdsa):
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in \/root\/.ssh\/id_ecdsa.
    Your public key has been saved in \/root\/.ssh\/id_ecdsa.pub.
    The key fingerprint is:
