# WHATPORT(1110)

## NAME

port 1110 — nfsd-status / webadmstart — Split registration: TCP is "start web admin server", UDP is NFS client status — and Nmap labels the TCP side nfsd-status.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registers 1110/tcp as webadmstart ("Start web admin server") and 1110/udp as nfsd-keepalive ("Client status info"), which is why Nmap's service list calls the TCP side nfsd-status and carries both names in its comments. It is the most frequently observed port in this block, historically alongside NFS status-monitor traffic on Solaris and other Unix hosts. Both readings of the registration point at infrastructure you would not publish: an administrative bootstrap endpoint or NFS-adjacent status.

## EXPOSURE

**Do not expose.** Either an admin-server hook or NFS status plumbing — both are internal-only. NFS-family services on a public IP are a long-standing compromise route.

## CHECK

```sh
sudo lsof -nP -iTCP:1110 -sTCP:LISTEN
```
