Hay un problema extraño con curl en el servidor Amazon Linux 2.
Falla con el código de salida 18 con aproximadamente ~1 MB de bytes para leer. Entonces, para solucionar el problema, configuré el servidor SFTP local.
entonces mi comando curl es así:
curl -u testuser:12345 -o /tmp/testfile sftp://127.0.0.1/home/testuser/testfile
Además, el problema no aparece si el tamaño del archivo es inferior a ~120 KB.
Ninguno de los siguientes cambios ayudó:
- No usando
-o - Citando la URL
- usando
--insecure - usando
localhosten lugar de127.0.0.1 - usando
-fantes de la URL
la salida de depuración usando -vvvno me dice nada,
la salida de seguimiento usando --traceno me dice nada,
Los datos de tcpdump están cifrados y no puedo saber qué está pasando.
Desearía poder compartir todos los resultados. Pero estoy trabajando en un escritorio remoto y no hay forma de transferir ningún archivo. Entonces no puedo compartir nada.
Entonces, ¿qué está pasando?
Y sí, si uso la sesión sftp y obtengo el comando, eso funciona.
salida de rizo:

Supongo que ha utilizado 127.0.0.1 como máscara para la dirección real o que está realizando algún reenvío.
Has probado:
curl -u usuarioprueba:12345 -o /tmp/testfile scp://127.0.0.1/home/testuser/testfile
scp está diseñado para funcionar en un solo canal a diferencia de sftp, y además scp no requiere una confirmación de cada paquete antes de enviar el siguiente. Es posible que scp pueda atravesar el firewall que está intentando eludir.
