SFTP - SETSTAT

[ebrain]

Good morning,
I try to copy via sftp files from windows to terramaster. I get an error Couldn't setstat on "xxxx": Permission denied.
However the file is copied but it can't change the rights.
I tried to activate the logs by modifying the file /etc/ssh/sftp_config :
# Logging
SyslogFacility AUTH
LogLevel DEBUG2

But I have no log file after restarting sftp
(/etc/init.d/sftp_service restart)

Has anyone had this problem before? And how to fix it?


P.S: excuse me for my english
