NAME
       opieserv - Example OPIE-based OTP server

SYNOPSIS
       opieserv
       [ principal ]

DESCRIPTION
       opieserv	 takes	an OTP principal (e.g., a user name)
       from either the command line or	standard  input	 and
       returns	a  current OTP challenge for that principal.
       It then reads an OTP response to that challenge	from
       standard	 input	and displays a message and returns a
       value to indicate either success (exit value = 0)  or
       failure	(exit value = 1). It is intended as an exam‐
       ple for programmers of how a simple OTP server can be
       built.

EXAMPLE
       wintermute$ opieserv kebe
       otp-md5 495 wi01309
       Response:
       User verified.
       wintermute$
