2 entries are registered on port 7676. It is a registered port (1024–49151) — IANA records an assignee, but nothing stops other software from listening here, which is why the number carries more than one entry.
Aqumin AlphaVision's Remote Command Interface (RCI) is a communication service that allows external applications and clients to remotely control the AlphaVision visualization environment. This facilitates integration within financial services, where AlphaVision is used to analyze large-scale financial datasets visually.
The registry says what 7676 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
linux
ss -ltnp | grep ':7676\b'
macos
lsof -nP -iTCP:7676 -sTCP:LISTEN
windows
netstat -ano | findstr :7676
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 7676 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
