Rsync no funciona como tarea programada

[Sys_VUn]

Lecquio, ahora desde el servidor Windows al tratar de ejecutar la tarea me indica:

Could not create directory '/home/Administrator/.ssh'.
The authenticity of host '192.168.1.21 (192.168.1.21)' can't be established.
RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:Xx.
Are you sure you want to continue connecting (yes/no)? yes
Failed to add the host to the list of known hosts (/home/Administrator/.ssh/know
n_hosts).

Sin embargo, desde Linux a Windows la relación de confianza funciona perfectamente. sabrás que puede estar sucediendo? Gracias
