# WHATPORT(2105)

## NAME

port 2105 — eklogin / MSMQ RPC (IANA: MiniPay) — Three claimants: IANA says MiniPay, Unix says Kerberos encrypted rlogin, Windows uses it for MSMQ RPC.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 2105 as MiniPay, which you will not encounter. Unix /etc/services and Nmap call it eklogin, the encrypted Kerberos rlogin service from the Kerberos v4 and early v5 era; MIT unbundled those application programs from krb5 at release 1.8 into the separate krb5-appl package, so a live eklogin daemon today is very old software. On Windows, 2105 is the second RPC port MSMQ uses for remote queue reads alongside 2103, which accounts for most of what scanners find here.

## EXPOSURE

**Do not expose.** Either reading is bad on a public interface: an abandoned Kerberized remote-login daemon, or an MSMQ RPC endpoint. Neither belongs outside a private network.

## CHECK

```sh
nc -vz TARGET 2105
```
