Thanks Peter, I had missed! Now the filsystem it's mounted properly.
Now I've a new trouble with FTP, (i don't know if i can ask about it in the same topic)
Using filezilla, the FTP server works very fine if i upload simple .txt files, however when i try to upload something like a pdf or a zip file, the transfer freezes at 100% and the transfer it's marked as not completed.
It may be due to the TCP buffer length? Or to the stack size of the task?
