.SH NAME
|
|
opiepasswd \- Change or set a user's password for the OPIE authentication
|
|
system.

|
.SH DESCRIPTION
|
|
.I opiepasswd
|
|
will initialize the system information to allow one to use OPIE to login.
|
|
.I opiepasswd
|
|
is downward compatible with the keyinit(1) program from the
|
|
Bellcore S/Key Version 1 distribution.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.TP
|
|
.B \-v
|
|
Display the version number and compile-time options, then exit.
|
|
.TP
|
|
.B \-h
|
|
Display a brief help message and exit.
|
|
.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
|
|
.B \-d
|
|
Disable OTP logins to the specified account.
|
|
.TP
|
|
.B \-f
|
|
Force
|
|
.I opiepasswd
|
|
to continue, even where it normally shouldn't. This is currently used to
|
|
force opiepasswd to operate in "console" mode even from terminals it believes
|
|
to be insecure. It can also allow users to disclose their secret pass phrases
|
|
to attackers. Use of the -f flag may be disabled by compile-time option in
|
|
your particular build of OPIE.
|
|
.TP
|
|
.B \-n
|
|
Manually specify the initial sequence number. The default is 499.
|
|
.TP
|
|
.B \-s
|
|
Specify a non-random seed. The default is to generate a "random" seed using
|
|
the first two characters of the host name and five pseudo-random digits.
|
|
.SH EXAMPLE
|
|
Using
|
|
.I opiepasswd
|
|

|
Then run opiepasswd without the \-c parameter.
