32-bit version of "OpenSSH Flipswitch"
Compatible with iOS 5?, 6-9, 10?. Tested on iOS 6,8,9 (and on 10.3.4 unsuccessfully).
iOS 10 jailbreaks often use Dropbear SSH, but it should still do its job if OpenSSH can be installed (in h3lix jb the OpenSSH works untraditionally, so this tweak doesn't work as expected).
OpenSSH Flipswitch. Can be used with eg. Activator to switch OpenSSH server on/off.
