Technical Details

what runs on :5025

SCPI is a text-based command language typically transported directly over a TCP socket. A client connects and sends newline-terminated commands; instruments return textual responses for queries, with command syntax, termination behavior, and session details varying somewhat by vendor. The IANA assignment also lists UDP, although deployed raw SCPI integrations are predominantly TCP-based; other instrument-control transports include VXI-11 and HiSLIP on different ports.

5/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

system averages 2.8 across 697 ports — this one sits 2.2 above.

tcp · udp

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

security overview

Raw SCPI is normally unencrypted and commonly lacks strong authentication, so anyone able to reach the port may be able to query measurements or issue control commands. It should generally be restricted to trusted laboratory or manufacturing networks and protected with network segmentation or access controls rather than exposed directly to the internet.
