# WHATPORT(15660)

## NAME

port 15660 — Backup Express restore server — IANA-registered to Syncsort/Catalogic Backup Express as its restore server port.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 15660 as bex-xr, "Backup Express Restore Server", to Catalogic Software (the product line that began as Syncsort Backup Express and is now DPX). It appears on hosts running that backup agent or server, alongside the product's other ports. Outside that product the number has no widely documented use, and it is rare on internet-wide scans.

## EXPOSURE

**Do not expose.** A backup control channel reaches every file on the protected host; keep it on the backup network and never on a public interface.

## CHECK

```sh
nc -vz -w 3 TARGET 15660
```
