# WHATPORT(32780)

## NAME

port 32780 — Unassigned / dynamic ONC RPC — The last port Nmap still labels as a Solaris RPC slot; unregistered at IANA.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

Like its neighbours, 32780 sits in IANA's unassigned 32778–32800 block. Nmap names it sometimes-rpc23 — "Sometimes an RPC port on my Solaris box" — and above this point its RPC naming becomes sparse. On Linux the port is ordinary ephemeral space (32768–60999), routinely used by outbound connections and by `docker run -P` publishes. Nothing chooses 32780 deliberately.

## EXPOSURE

**Expose with care.** The exposure question belongs to whichever program grabbed the port; nothing about the number itself makes it safe or unsafe.

## CHECK

```sh
rpcinfo -p TARGET
```
