# WHATPORT(8100)

## NAME

port 8100 — Xprint Server — Registered to the X.Org print server, a subsystem that no longer ships.

Protocol: TCP  
IANA: xprint-server

## DESCRIPTION

IANA assigns 8100 on TCP and UDP to xprint-server, the Xprint printing extension that shipped with XFree86 and Solaris and was removed from X.Org years ago. You will not meet a live Xprint server today. What you find on 8100 now is a locally chosen listener — it is a round number in the 80xx band, so applications and containers take it as an alternate HTTP or service port.

## EXPOSURE

**Expose with care.** The registration is dead history; identify the actual service before deciding anything about it.

## CHECK

```sh
nc -vz TARGET 8100
```
