Technical Details

what runs on :9598

VSCP is an event-oriented automation protocol organized around Level I and Level II events, including event class, type, addressing, and optional data. Its TCP service provides a client/server command and event interface, while UDP can carry VSCP event traffic without a reliable session. The protocol is not encrypted by default; authentication and any transport protection depend on the particular VSCP daemon or deployment.

security overview

An exposed VSCP endpoint may allow an attacker to observe automation events, inject control events, or disrupt connected devices, depending on its configuration and access controls. It should normally be restricted to trusted automation networks or protected with filtering and a secure tunnel rather than exposed directly to the Internet.
