OPIEKEY(1) General Commands Manual OPIEKEY(1)
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 example for programmers of how a simple OTP server can be
built.
EXAMPLE
wintermute$ opieserv kebe
otp-md5 495 wi01309
Response:
User verified.
wintermute$
