When I saw a similar SSH error, it was actually PAM having decided that
there'd been too many bad login attempts and was locking out any attempt
to connect.

If it blocks, it will also prevent access to SSH and anything else
going through PAM from the IP involved.

You *could* try connecting to the box from a different IP if you're going
in via ethernet.

As I recall, I eventually had to use a serial terminal console and boot
the box into single user mode and then use the PAM tools (pam_abl, I
think) to force reset of the PAM blocking database and login counters.
It wasn't fun.

Good luck!
