as you can see, bsdauth (skey) isn't supported by this ssh. I think you're
trying to run Gobbles exploit sshutup-theo (tnx to them ;) against system
which hasn't got SKEY feature available. BTW: OpenBSD is default exploitable
only, cause it has got SKEY mechanism available in default SSH. Some people
did Linsux version of this exploit, but I haven't got it, so I don't test it.
