I set up a jail for a remote user under SSH (Cygwin), and he is jailed at
/jail/user/home/user. When he connects with some SFTP client (ex: Filezilla), he can access his
/home/user folder and control it, but also
/dev folder too. In this folder, he can read, write, but not delete or download files.
There's something wrong with
ChrootDirectory directive in sshd_config file?
