ssh and rsync for Android

I got somewhat tired of using FTP with my Android, even with lftp. Keeping multiple folders in sync is simply very cumbersome. If I only had rsync working on Android! I found SSHelper, written by Paul Lutus, see also Arachnoid.

SSHelper offers ssh, scp, rsync. You can ssh to your Android phone and issue commands like vi, ls, top, uptime, etc.

Put your public key into .ssh/authorized_keys on the smartphone then you can log-on without being prompted any password. This is very convenient.

Sample screenshot is given below.

Added 28-Oct-2013: The recent update to version 2.3 of SSHelper unfortunately is completely broken. It doesn’t start, no shell. I wished I had not updated. You probably have read this more than once in this blog: Newer is not better.

Added 05-Nov-2013: SSHelper is running again. Important notice from www.arachnoid.com: users must fully uninstall, then reinstall SSHelper.
