.SH NAME
|
|
|
|
|
opiesu \- Replacement su(1) program that uses OPIE challenges
|
|

|
|
.SH SYNOPSIS
|
|
|
|
|
.B opiesu
|
|
|
|
|
[ \-f ] [ \-c ] [

|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
.I 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.
|
|
|
|
|
.SH OPTIONS
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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.)
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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.
|
|
|
|
|
.TP
|
|
|
|
|
.I user_name
|
|
|
|
|
The name of the user to become.
|
|
|
|
|
The default is root.
