RVR-SSH-400

1. Issue Summary

   • The error encountered is an External SSH error with the error code RVR-SSH-400 indicating a failed connection when attempting to establish an SSH connection via Rivery's Data Connector for SSH. This problem typically arises due to configuration issues or network connectivity problems between the Rivery platform and the specified SSH server.

2. Action Steps:

   • Check SSH Server Accessibility: Ensure that the SSH server you are trying to connect to is accessible externally. This includes verifying that it is running and accepting connections on the designated port, usually port 22.
   • IP Whitelisting: Ensure that the IP addresses used by Rivery are whitelisted on your SSH server. This is crucial for establishing a connection. You can find the necessary IP addresses in the Rivery documentation or the setup instructions you followed .
   • SSH Credentials Verification: Double-check the SSH credentials used in the Rivery connection settings. Confirm the accuracy of the SSH hostname, port, username, and the private key provided.
   • Firewall and Network Security: Make sure that any firewalls or security groups allow incoming SSH connections from Rivery's IP addresses. This may require configuring your network's firewall rules or the SSH server's security settings.
   • SSH Configuration Adjustment: Update your SSH configuration as needed. Enable verbose logging by setting LogLevel VERBOSE in /etc/ssh/sshd_config to gather more detailed information about connection attempts. Also, ensure settings like AllowAgentForwarding yes and PubkeyAuthentication yes are correctly configured.
   • Testing Connection: Use the 'Test Connection' feature in Rivery after making adjustments to verify if the connection can now be established successfully .
