# WHATPORT(2035)

## NAME

port 2035 — imsldoc (registration only) — An IANA name with nothing behind it — no description, no assignee, no published protocol.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registers the service name imsldoc on TCP and UDP 2035 with no description, no assignee and no reference document, which is typical of early bulk port registrations that were never written up. No widely deployed software claims the port, and Nmap's frequency data ranks it among the rarest it tracks (open on roughly 0.02% of scanned hosts). If you find 2035 listening, the registry label tells you nothing useful — identify the process on the host instead.

## EXPOSURE

**Expose with care.** The name carries no meaning, so an open 2035 is an unidentified service. Find the owning process before deciding whether it belongs on a public interface.

## CHECK

```sh
sudo lsof -nP -iTCP:2035 -sTCP:LISTEN
```
