requests a password from the user, reads it again for verification
|
|
|
|
|
and then will normally not relinquish the terminal until the password is
|
|
|
|
|
repeated.
|
|
|
|
|
There are two other conditions under which it will terminate: it
|
|
|
|
|
will timeout after some interval of time and it may be killed by someone
|
|
|
|
|
with the appropriate permission.

If the user has an S/Key key, they may also use it
|
|
|
|
|
to unlock the terminal. To do this the user should enter "s/key"
|
|
|
|
|
at the unlock "Key:" prompt. The user will then be issued an S/Key
|
|
|
|
|
challange to which they may respond with a six-word S/Key one-time
|
|
|
|
|
password.
