When deploying a bare-metal on-prem host, you must open applicable ports on the host, to ensure that all services are functioning properly. The following table lists the ports that need to be available on the bare-metal on-prem host, in addition to the port usage for firewalls, as described in BloxOne Connectivity and Service Requirements.
| IP Protocol | Port | Services using this port | Description |
|---|---|---|---|
| TCP | 22 |
| Required for an incoming SCP data transfer from NIOS to Data Connector when deployed as a container. When you deploy Data Connector as a container, ensure that there are no SSH processes listening on port 22. You must terminate these SSH processes for Data Connector to collect data from NIOS. |
| TCP | 53 | On-prem hosts | Ensure that there are no other processes using port 53 on the host system on which your on-prem host will be deployed. For example, some Ubuntu systems running a local DNS cache (system-resolved) might occupy port 53, and your on-prem host might not function properly in this case. |
| TCP | 514 | Data Connector | Required for a Data Connector secure syslog for RPZ hits data. If you deploy Data Connector as a container, ensure that this port is not used by other processes. |
| TCP | 2222 | On-prem hosts | Used by an internal service for remote monitoring. |
| TCP | 6514 |
| Used for transferring syslog data from NIOS to Data container. Port 6514 is a default secure port. If you deploy Data Connector as a container, ensure that this port is not used by other processes. |
| TCP | 8125 | Data Connector | This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes. |
| TCP | 8126 | Data Connector | This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes. |
| TCP | 50514 | Data Connector | This is an internal port used for communications between containers. If you deploy Data Connector as a container, ensure that this port is not used by other processes. |
