# WHATPORT(2718)

## NAME

port 2718 — pn-requester2 (registered) — The second half of the pn-requester registration, and just as undocumented as the first.

Protocol: TCP/UDP  
IANA: pn-requester2

## DESCRIPTION

IANA registers 2718 as pn-requester2, "PN REQUESTER 2", the companion to 2717. As with 2717 there is no public specification or named implementation; unlike 2717, it is also rare in scan data. If you find it listening, the only honest identification is the local process behind it.

## EXPOSURE

**Expose with care.** Nothing well-known should be here, so identify the listener before you decide it is safe to reach from anywhere.

## CHECK

```sh
sudo lsof -nP -iTCP:2718 -sTCP:LISTEN
```
