Technical Details

what runs on :2542

IANA assigns port 2542 for uDraw(Graph) over both TCP and UDP. The service is associated with the uDraw(Graph) graph-rendering and editing application and its client/API communication; deployments are generally expected to use a persistent TCP connection, while the registry does not document a standard UDP exchange, framing format, or encryption mechanism. It is not a general-purpose web, database, or remote-login protocol.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

uDraw(Graph) should normally be restricted to localhost or a trusted management/application network. Because the service is not encrypted by default and may expose graph-editing or application-control functionality to connected clients, an Internet-exposed listener could permit unauthorised interaction or disclosure of graph data; the service is obscure, so fingerprinting and implementation-specific testing are likely.
