.Sh DESCRIPTION
|
|
.Nm Keyinit
|
|
initializes the system so you can use S/Key one-time passwords to
|
|
login. The program will ask you to enter a secret pass phrase; enter a
|
|
phrase of several words in response. After the S/Key database has been
|
|
updated you can login using either your regular UNIX password or using
|
|
S/Key one-time passwords.
|
|
.Pp
|
|
When logging in from another machine you can avoid typing a real
|
|
password over the network, by typing your S/Key pass phrase to the
|
|
.Nm key
|
|
command on the local machine: the program will respond with
|
|
the one-time password that you should use to log into the remote
|
|
machine. This is most conveniently done with cut-and-paste operations
|
|
using a mouse. Alternatively, you can pre-compute one-time passwords
|
|
using the
|
|
.Nm key
|
|
command and carry them with you on a piece of paper.
|
|
.Pp
|
|
.Nm Keyinit
|
|
requires you to type your secret password, so it should
|
|
be used only on a secure terminal. For example, on the console of a
|
|
workstation. If you are using
|
|
.Nm
|
|
while logged in over an
|
|
untrusted network, follow the instructions given below with the
|
|
.Fl s
|
|
option.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width indent
|
|
.It Fl s
|
|
Set secure mode where the user is expected to have used a secure
|
|
machine to generate the first one time password. Without the
|
|
.Fl s
|
|
the
|
|
system will assume you are direct connected over secure communications
|
|
and prompt you for your secret password.
|
|
The
|
|
.Fl s
|
|
option also allows one to set the seed and count for complete
|
|
control of the parameters. You can use
|
|
.Nm
|
|
.Fl s
|
|
in combination with
|
|
the
|
|
.Nm key
|
|
command to set the seed and count if you do not like the defaults.
|
|
To do this run
|
|
.Nm
|
|
in one window and put in your count and seed
|
|
then run
|
|
.Nm key
|
|
in another window to generate the correct 6 English words
|
|
for that count and seed. You can then
|
|
"cut" and "paste" them or copy them into the
|
|
.Nm
|
|
window.
|
