Não é possível abrir a porta 4444 no gufw

Question

Eu adicionei uma regra SSH para adicionar 4444 portas na minha distro através do gufw, mas quando eu corro

nmap -sV 10.9.0.136 -A

mostra:

Starting Nmap 7.40 ( https://nmap.org ) at 2017-04-25 11:30 IST
Nmap scan report for 10.9.0.136
Host is up (0.00013s latency).
All 1000 scanned ports on 10.9.0.136 are closed
Too many fingerprints match this host to give specific OS details
Network Distance: 0 hops
OS and Service detection performed. Please report any incorrect results at https://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 3.50 seconds

O que estou fazendo de errado?

"Por padrão, o Nmap verifica as 1.000 portas mais comuns para cada protocolo."

Tente especificar -p4444
