Which port is used for secure, agent-initiated communication when deploying Orion agents (Windows and Linux)?

• A. 17778
• B. 161
• C. 443
• D. 22

Answer: (A)

Orion Agent communication uses a dedicated outbound channel from the node to the Orion server. This secure, agent-initiated path runs over port 17778, providing TLS-encrypted traffic for the deployment and ongoing data from Windows and Linux agents. The key idea is that the agent connects out to the server, which is firewall-friendly since you mainly allow outgoing connections to the Orion service. Port 17778 is specifically for this agent-to-server traffic. The other ports serve different purposes: 161 is SNMP (usually UDP) for polling devices via SNMP, 443 is the web interface HTTPS port for the Orion web console, and 22 is SSH for remote shell access. None of these are the designated secure channel used by the Orion Agent to communicate with the server.
