This tutorial explain how to install SFTP server using MySecureShell on Ubuntu 15.10 server.MySecureShell is a solution which has been made to bring more features to sftp/scp protocol given by OpenSSH. By default, OpenSSH brings a lot of liberty to connected users which imply to thrust in your users. The goal of MySecureShell is to offer the power and security of OpenSSH, with enhanced features (like ACL) to restrict connected users.

MySecureShell was created because of the lack of file transfer features in OpenSSH. OpenSSH was not designed as a file transfer solution, that’s why we made MySecureShell.
