Issue
When attempting to ping an ARCNET controller from a server using the DOS ping command, the operation fails with the error:
"Destination host unreachable"
Product Line
Satchwell BAS & Sigma
Environment
Satchwell Sigma
Cause
This issue typically occurs due to incorrect or missing routing configurations. Specifically:
- The route to the ARCNET sub-net is not defined.
- Sigma DNN broadcasts RIP v1 messages for the Sigma server to interpret.
- By default, RIP Listener is disabled on Windows XP and later systems, preventing dynamic route updates.
Resolution
To resolve this issue, follow one or both of the steps below:
-
Enable RIP Listener on the Server
- This allows the Sigma server to receive and process RIP v1 messages from the DNN.
- Refer to: Sigma server communication to ARCNET/Ethernet sub-nets via a DNN failing
-
Add Persistent Routes to the Sigma Server
- Manually define static routes to ensure reliable communication with ARCNET controllers.
- Refer to: Persistent routing on the Sigma server
