Realizo un escaneo agresivo de puertos con nmap, lo que me permite identificar rápidamente todos los puertos abiertos.

/home/kali/Documents/htb/machines/nocturnal:-$ sudo nmap -p- --open -sS --min-rate 5000 -vvv 10.129.231.237 -n -Pn -oG nmap1

Host: 10.129.231.237 () Ports: 22/open/tcp//ssh///, 80/open/tcp//http///

Profundizo en los puertos detectados, recopilando información detallada sobre los servicios y versiones en ejecución.
