# WHATPORT(2602)

## NAME

port 2602 — ripd VTY (FRR / Quagga) — The RIP daemon's telnet config shell, one number up from zebra's.

Protocol: TCP  
IANA: discp-server

## DESCRIPTION

FRR assigns each routing daemon a VTY port counting up from 2601: zebra 2601, ripd 2602, ripngd 2603, ospfd 2604, bgpd 2605, and so on. So 2602 open means ripd — the RIP/RIPv2 implementation — is running with its TCP VTY enabled, and finding it usually means its siblings are listening too. As with zebra, the supported way in is `vtysh` over local sockets, and the TCP VTY can be bound to localhost or disabled by passing port 0. IANA's registration for 2602 is discp-server, which has nothing to do with routing.

## EXPOSURE

**Do not expose.** Cleartext telnet into a routing daemon's configuration shell; anyone who reaches it and knows the VTY password can alter what the router advertises.

## CHECK

```sh
nc -v 127.0.0.1 2602
```
