Logging in to the iBMC CLI by Configuring the SSH User Private Key

Logging in to the iBMC CLI by Configuring the SSH User Private Key

Operation Scenario

Two authentication modes are available when users log in to iBMC over SSH.
  • Password authentication: Users need to enter passwords upon every login. This method is inconvenient and may leak passwords.
  • Private key authentication: After the configuration, users do not need to enter passwords upon login. To log in to iBMC over SSH, users must use a client has the correct private key, so security is improved.

This topic describes how to manage SSH private keys and log in to iBMC through SSH private key authentication.



  • A local client can communicate with the server iBMC.
  • The SSH interface has been enabled for the user on the iBMC.


  • SSH public key type: RSA or DSA
  • IP address of the iBMC management network port
  • SSH service port number


  • Login tool, such as putty.exe.
  • Private key generation tool, such as puttygen.exe.

The preceding tools are free. Download them from the Internet by yourself.


    Generate the SSH private key.

    1. On the client (such as a PC), open the private key generation tool, such as puttygen.exe, as shown in Figure 4-31.
