NAME

       opielogin - Replacement for login(1) that issues OPIE challenges.

SYNOPSIS

       opielogin [ -p ] [ -r hostname | -h hostname | -f username
       | username ]

DESCRIPTION

       opielogin provides a replacement for the login(1) program that provides OPIE challenges to users and accepts OPIE responses. It is downward
       compatible with the keylogin(1) program from the Bellcore S/Key Version 1 distribution, which, in turn, is  downward  compatible  with  the
       login(1) program from the 4.3BSD Net/2 distribution.

OPTIONS

       -p     By default, login discards any previous environment.  The -p option disables this behavior.

       -r     Process remote login from hostname.

       -h     The  -h  option  specifies the host from which the connection was received.  It is used by various daemons such as telnetd(8).  This
	      option may only be used by the super-user.

       -f     The -f option is used when a user name is specified to indicate that proper authentication has already been done and that  no  pass-
	      word  need  be  requested.   This option may only be used by the super-user or when an already logged in user is logging in as them-
	      selves.

       username
	      The user name to log in as.
