# WHATPORT(617)

## NAME

port 617 — sco-dtmgr — SCO Desktop Administration Server — the companion to 616 on the same extinct Unix line.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers TCP and UDP 617 as "sco-dtmgr", the SCO Desktop Administration Server, part of the same block of SCO administrative services as sco-sysmgr on 616. Like its neighbour it belongs to SCO OpenServer/UnixWare systems that have been out of general use for many years. There is no current documentation for the wire protocol and no maintained client, so an open 617 is worth fingerprinting rather than assuming.

## EXPOSURE

**Do not expose.** An administrative service on unsupported legacy Unix — internal networks only, and preferably not at all.

## CHECK

```sh
nc -vz -w 3 TARGET 617
```
