What Are the Login Requirements for ECSs?

Linux

• Ensure that the ECS has an EIP bound (only required for SSH access).
  SSH access is only available for Linux ECSs. You can use a remote login tool to log in to your ECS. Ensure that the ECS has an EIP bound. For example, use PuTTY to log in to the ECS.

  • Check whether an ECS has an EIP bound.

    For details, see Assigning an EIP.

  • Check whether an EIP can be pinged.
    • If an EIP is used for SSH access but the EIP cannot be pinged, see What Should I Do If an EIP Cannot Be Pinged?
    • If a private IP address is used for SSH access but it cannot be pinged, see Why Does Communication Fail Between Two ECSs in the Same VPC or Packet Loss Occur When They Communicate?

  • For a Linux ECS authenticated using a key pair:
    • For the first login, use an SSH key. For details, see Logging In to a Linux ECS Using an SSH Key Pair.
    • For a non-first login, if you want to use the remote login function (VNC) provided by the management console, log in to the ECS using the SSH key and set the password.
  • For an ECS purchased using a key pair, if you fail to log in to the ECS using a private key file, the possible cause is that the password fails to be injected using Cloud-Init.
