Configuring the SSH User Private Key

Configuring the SSH User Private Key

Operation Scenario

Configure the SSH private key.

After the SSH private key has been loaded on the user client and the iBMC, the user can log in to the iBMC CLI over SSH without entering a password. This access mode is recommended due to higher security and easier operation.



  • The client (local PC) can communicate with the server iBMC.
  • The SSH interface has been enabled on the iBMC.


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


  • A free tool, such as putty.exe, to log in to the iBMC
  • A free tool, such as puttygen.exe, to generate private keys


    Generate an SSH private key.

    1. On the client (such as a PC), run puttygen.exe.

      The PuTTY Key Generator window is displayed, as shown in Figure 6-24.
