Relink Sensors Directly

If you uninstall Sensor Proxy, you remove it from the communication chain between sensors and Tenable Vulnerability Management or Tenable Security Center. Therefore, before you uninstall Sensor Proxy, you must first relink sensors directly to Tenable Vulnerability Management or Tenable Security Center. Otherwise, the sensors cannot communicate with Tenable Vulnerability Management or Tenable Security Center.

Note: If you are connecting to Tenable Vulnerability Management through Tenable Nessus scanners or Tenable Nessus Agents located in mainland China, you must connect through sensor.cloud.tenablecloud.cn instead of sensor.cloud.tenable.com.

To relink a Tenable Nessus Agent directly

Note: Tenable Security Center 6.5 only supports Sensor Proxy linked with Tenable Web App Scanning scanners. Tenable Nessus scanners and Tenable Nessus Agents are currently unsupported. Tenable Vulnerability Management supports Sensor Proxy linked with all sensors except Tenable Web App Scanning scanners.

You can relink the agent directly to Tenable Vulnerability Management and remove Sensor Proxy from the communication chain. You do not need the Tenable Vulnerability Management linking key.

On the agent, use the following command:
Copy
```
# nessuscli agent relink --host=sensor.cloud.tenable.com --port=443
```
The agent unlinks from Sensor Proxy and relinks to Tenable Vulnerability Management directly.

To relink a Tenable Nessus scanner directly

On the Tenable Nessus scanner, use the following command:
Copy
```
# nessuscli managed unlink
```
The scanner unlinks from Sensor Proxy.
For Tenable Vulnerability Management, link the scanner directly as described in Link a Sensor in the Tenable Vulnerability Management Vulnerability Management User Guide.

What to do next:

(Optional) Uninstall Sensor Proxy
