Hmm. Either the server's list of auth-methods it sends
doesn't include any which we can use, or Dropbear's handling
of them is broken (I think).

Would it be possible for you to get a copy of Dropbear
compiled with DEBUG_TRACE enabled in debug.h, and run it
with a "-v" flag? That should help in hunting down what's
happening. Alternatively, you could try running the desktop
server with "sshd -p 2244 -ddd" as root, sshing to desktop
port 2244, and looking at those debug logs.

Thanks,
Matt
