# WHATPORT(1461)

## NAME

port 1461 — IBM Wireless LAN — Registered as IBM Wireless LAN; a 1990s assignment with no current documentation.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registers 1461 on TCP and UDP as ibm-wrless-lan, "IBM Wireless LAN" (the well-formed name IANA issued to replace the older ibm_wrless_lan spelling). It dates from IBM's pre-802.11 wireless LAN products and there is no published protocol specification or supported implementation today. Nothing well-documented squats here, so an open 1461 should be traced to its process on the host rather than read off the registry.

## EXPOSURE

**Expose with care.** Unknown service; identify the listener before deciding whether it should be reachable at all.

## CHECK

```sh
sudo lsof -nP -iTCP:1461 -sTCP:LISTEN
```
