If a SPP asset requires an SSH host key and does not have one, SPP will not be able to communicate with the asset. For more information, see Certificate issue.

To resolve missing SSH host keys

To verify that an asset has an SSH host key, select the asset and look under Connection on the General view. If there is no SSH Host Key Fingerprint displayed, you need to add one.

To add an SSH host key

  1. Open the asset's Connection tab.

  2. Choose any authentication type (except None) and enter required information.

    NOTE: You must enter the service account password or SSH key again.

  3. Click Test Connection.

    Test Connection verifies that the appliance can communicate with the asset.

  4. Confirm that you accept the SSH host key.

    NOTE: To bypass the SSH host key verification and automatically accept the key, click the Auto Accept SSH Host Key option.

  5. Click OK to save asset.

To resolve incorrect SSH host keys

SPPuses the following host key algorithms for key exchange:

  • DSA
  • ECDSA
  • RSA

Investigate the cause of the mismatch and then use Test Connection to resolve the mismatch.
