# WHATPORT(9010)

## NAME

port 9010 — Secure Data Replicator Protocol (registered) — Registered as sdr on TCP and Reserved on UDP; day to day it is an anonymous application port.

Protocol: TCP  
IANA: sdr

## DESCRIPTION

IANA registers 9010/tcp as sdr, the Secure Data Replicator Protocol, and marks 9010/udp Reserved. Neither shows up much. Because it sits in the 90xx band that Java and JVM tooling likes for management and debug endpoints, a listener on 9010 is most often a locally configured application port rather than the registered protocol. Confirm by process before drawing conclusions.

## EXPOSURE

**Expose with care.** If this turns out to be a JVM management or debug endpoint, treat it as never — those grant code execution to anyone who can connect.

## CHECK

```sh
sudo lsof -nP -iTCP:9010 -sTCP:LISTEN
```
