OPIESU(1)						      General Commands Manual							 OPIESU(1)

NAME

       opiesu - Replacement su(1) program that uses OPIE challenges

SYNOPSIS

       opiesu [ -f ] [ -c ] [ user_name ]

DESCRIPTION

       opiesu  is a replacement for the su(1) program that issues OPIE challenges and uses OPIE responses. It is downward compatible with keysu(1)
       from the Bellcore S/Key Version 1 distribution and the su(1) program from the 4.3BSD Net/2 distribution.

OPTIONS

       -f     If the invoked shell is csh(1),  this option prevents it from reading the ``.cshrc'' file.  (The [f] option may be passed as a shell
	      argument after the login name, so this option is redundant and obsolescent.)

       -c     Set  console  mode  where the user is expected to have secure access to the system. In console mode, you will be asked to input your
	      password directly instead of having to use an OPIE calculator. If you do not have secure access to the system (i.e., you are not	on
	      the system's console), you are volunteering your password to attackers by using this mode.

       user_name
	      The name of the user to become.  The default is root.

EXAMPLE

       wintermute$ opiesu kebe
       otp-md5 498 wi910502
       (OTP response required)
       kebe's password:  (echo on)
       kebe's password: RARE GLEN HUGH BOYD NECK MOLL
       wintermute#

FILES

       /etc/opiekeys database of information for OPIE system.
