# WHATPORT(3005)

## NAME

port 3005 — Genius License Manager (registered) / deslogin — Registered to a license manager; still labelled deslogin, a 1990s DES-encrypted remote login tool.

Protocol: TCP/UDP  
IANA: geniuslm

## DESCRIPTION

IANA registers 3005 as geniuslm, "Genius License Manager". Nmap and older service tables instead call it deslogin, an early encrypted-symmetric replacement for telnet/rlogin from before SSH existed, which is the label most scanners will print. Neither is common today; floating license daemons are the more plausible modern occupant of the 3000-3010 range on a workstation running commercial engineering software.

## EXPOSURE

**Expose with care.** If it is a license manager, it should be reachable only from the LAN that needs licenses; if it really is a pre-SSH remote login daemon, treat it as never and remove it.

## CHECK

```sh
nc -vz -w 3 TARGET 3005
```
