SSHelper

SSHelper is an advanced, multi-protocol, secure server for the Android platform.
SSHelper works just fine with a normal, unrooted Android device — i.e. your device.
SSHelper works as an application and as a service. As a service it runs in the background, providing secure communications protocols without requiring user attention.
SSHelper supports interactive Secure Shell (hereafter SSH) sessions and various kinds of transfers including scp, sftp, and rsync, on all common platforms:
On Windows, SSHelper works with WinSCP, PuTTY and similar programs.
On Linux, apart from normal SSH shell session activities, SSHelper can be used directly with file browsers for seamless filesystem browsing and transfers by specifying the "sftp:" protocol.
On the Mac, SSHelper works with Cyberduck and similar programs.
SSHelper is free, open-source and there are no ads. It's licensed under the GPL and the source is freely available.
