Technical Details

what runs on :6200

LM-X License Manager handles license requests from client software, such as license checkouts and status checks. Port 6200 is the usual service port, though deployments can configure a different port. IANA lists both TCP and UDP; TCP is the normal client-server path, while the protocol’s proprietary details and any UDP use depend on the deployment. LM-X uses encrypted communication between clients and the license server by default; there is no general-purpose administrative protocol implied by this port.

security overview

Keep the license service reachable only by systems that need to obtain licenses, typically using firewall rules or a VPN rather than exposing it broadly to the internet. An exposed listener may reveal license-service availability and can be targeted to disrupt access or consume license capacity; encryption does not remove those availability risks. This port is not, by itself, evidence of a known exploitable vulnerability or an unauthorized service.
