@00za: What the KUAL button shows is what's *pushing* the button is going to do. i.e., if you're seeing the "Use dropbear" button, you're currently using OpenSSH.
Which we already knew, since you posted the version string from the sshd above

. Unless that was your *client*.
Dropbear's, is, appropriately enough:
Code:
Remote protocol version 2.0, remote software version dropbear_2019.78
@WaseemAlkurdi: Nope, that's also dropbear, and that's the exact same patch as used in USBNet (because it's also mine ;p). And it's also disabled by default (both the sshd, and passwordless logins).
It's also slightly outdated because I can't be arsed to maintain two set of slightly different patches for a feature I don't use (KOReader's sshd, I mean, since I maintain USBNet).
