Hmm... I see.  I finally have it running after tweaking the skey and 
and OpenSSH.  

And I see what you mean.. And this is on a linux/i86 box.

Challenge states: 40 etoh54947
It should state: 98 etoh39309

I doubt it's any type of endedness.  I think it's a problem with
OpenSSH portable code.  (doing a diff -u of auth-skey.c and you'll
notice large blocks of function changes..Which I'm attempting to track

I think there is a good reason why it was disabled. =)

Does anyone have this code working correctly on any platform (besides the
given OpenBSD =)??
