También puedo usar el escáner de puerto tcp de metasploit y puedo encontrar puertos abiertos pero esta dosis no funciona.

Parece que no puede enviar paquetes ICMP a través de SOCKS. ¡Pero puede indicar a Nmap que realice un ping TCP para hacer lo mismo!

  

El "ping TCP" se puede describir como un paquete TCP con el indicador ACK establecido,   destinado al puerto 80 del host (s) de destino. La respuesta deseada de un   host accesible es un paquete TCP con el conjunto de indicadores RST o un eco ICMP   respuesta, indicando que el host está vivo.

Si, como supongo, proxychains está configurado para usar la red Tor, esto evitará el uso de la solicitud ICMP (ping).

Por ejemplo, si intenta ejecutar el siguiente comando:

proxychains ping 8.8.8.8

Esto devolverá muchos errores porque Tor no permite ICMP. Si desea ejecutar un escaneo desde la red Tor, debe excluir la prueba de ping con el indicador -Pn .

Este indicador ralentizará tu escaneo pero, al menos, funcionará.
