Clé SSH Private/Public sur esxi

To allow SSH access to ESXi/ESX hosts with public/private key authentication:

  1. Generate public/private keys.
    • These instructions generate two files in ~/.ssh: id_rsa and
    • In ESXi 5.x, the ssh-keygen command is located at /usr/lib/vmware/openssh/bin.
  2. On the remote host, store the public key content, id_rsa.pubin ~/.ssh/authorized_keys.
    • For ESXi 5.x, 6.0 and 6.5, the authorized_keys is located at: /etc/ssh/keys-<username>/authorized_keys
    • More than one key can be stored in this file.
  3. To allow root access, change PermitRootLogin no to PermitRootLogin yes in the /etc/ssh/sshd_config file.
  4. To disable password login, ensure that the ChallengeResponseAuthentication and PasswordAuthentication are set to no.
  5. Reload the service:
    • For ESXi, run the command:/etc/init.d/SSH restart
    • For ESX, run the command:service sshd reload
