Adding the Connector in Stellar Cyber

To add a new remote SSH host connector in Stellar Cyber:

  1. Log in to Stellar Cyber.

  2. Click System | INTEGRATIONS | Connectors. The Connector Overview appears.

  3. Click Create and select Connector.

    The General tab of the Add Connector screen appears. The information on this tab cannot be changed after you add the connector.

  4. Choose Remote Host from the Category dropdown.

  5. Choose SSH Host from the Type dropdown.

    The asterisk (*) indicates a required field.

  6. For this connector, the supported Function is Respond, which is enabled already.

  7. Enter a Name.

    Notes:
    • This field does not accept multibyte characters.
    • It is recommended that you follow a naming convention such as tenantname-connectortype.

  8. Choose a Tenant Name. The Interflow records created by this connector include this tenant name.

  9. Choose the device on which to run the connector.

  10. Click Next. The Configuration tab appears.

    11. The asterisk (*) indicates a required field.

  11. Enter the Hostname.

    Do include https in the Hostname.

  12. Enter the Port.

  13. Enter the Username to log in to the SSH host.

  14. Enter the Password.

    The password should not include non-ASCII special characters.

  15. Click Next. The final confirmation tab appears.

  16. Click Submit.

The remote host is immediately added.

Testing the Connector

When you add (or edit) a connector, we recommend that you run a test to validate the connectivity parameters you entered. (The test validates authentication and connectivity).

For connectors running on a sensor, Stellar Cyber recommends that you allow 30-60 seconds for new or modified configuration details to be propagated to the sensor before performing a test.

  1. Click System | INTEGRATIONS | Connectors. The Connector Overview appears.

  2. Locate the connector by name that you added, or modified, or that you want to test.

  3. Click Test at the right side of that row. The test runs immediately.

    Note that you may run only one test at a time.

Stellar Cyber conducts a basic connectivity test for the connector and reports a success or failure result. A successful test indicates that you entered all of the connector information correctly.

To aid troubleshooting your connector, the dialog remains open until you explicitly close it by using the X button. If the test fails, you can select the  button from the same row to review and correct issues.

The connector status is updated every five (5) minutes. A successful test clears the connector status, but if issues persist, the status reverts to failed after a minute.

Repeat the test as needed.

If the test fails, the common HTTP status error codes are as follows:

HTTP Error Code HTTP Standard Error Name Explanation Recommendation
400 Bad Request This error occurs when there is an error in the connector configuration.

Did you configure the connector correctly?
401 Unauthorized

This error occurs when an authentication credential is invalid or when a user does not have sufficient privileges to access a specific API.

Did you enter your credentials correctly?

Are your credentials expired?

Are your credentials entitled or licensed for that specific resource?
403 Forbidden This error occurs when the permission or scope is not correct in a valid credential.

Did you enter your credentials correctly?

Do you have the required role or permissions for that credential?

404 Not Found This error occurs when a URL path does not resolve to an entity. Did you enter your API URL correctly?
429 Too Many Requests

This error occurs when the API server receives too much traffic or if a user’s license or entitlement quota is exceeded.

The server or user license/quota will eventually recover. The connector will periodically retry the query.

If this occurs unexpectedly or too often, work with your API provider to investigate the server limits, user licensing, or quotas.
