# WHATPORT(1201)

## NAME

port 1201 — Nucleus Sand Database Server — IANA-registered to the Nucleus Sand database server; a historical assignment you will rarely encounter.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

Port 1201 is registered on TCP and UDP as nucleus-sand, "Nucleus Sand Database Server", assigned to James Marsh. The Sand analytic database (later Sand Technology's Nucleus/SAND CDBMS) is a niche column-store product with no current public protocol documentation at this port. There is nothing else well documented that habitually squats here, so an open 1201 on a modern host is almost certainly an unrelated program that grabbed a free registered port.

## EXPOSURE

**Expose with care.** If this really is a database listener it belongs on a private network; if it is not, identify the process before leaving it reachable.

## CHECK

```sh
sudo lsof -nP -iTCP:1201 -sTCP:LISTEN
```
