Technical Details

what runs on :5044

The LXI Event Service is part of the LAN eXtensions for Instrumentation (LXI) standards for coordinating events and triggers among networked test instruments. Event traffic is typically sent as UDP datagrams, including to multicast destinations when instruments need to distribute events to multiple peers; the registry also lists TCP, but the exact use can depend on the LXI implementation. It is generally encountered on an instrument's lab network rather than on ordinary servers.

tcp · udp

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

security overview

Base event traffic should not be assumed to be encrypted, and reachable instruments may accept event messages that affect test sequencing or trigger behavior. Keep the service on a trusted, segmented instrumentation network and restrict access to the specific instruments and peers that need it; there is little reason to expose it to the public internet.
