.SH DESCRIPTION
|
|
|
|
|
.I opielogin
|
|
|
|
|
provides a replacement for the
|
|
|
|
|
.IR login (1)
|
|
|
|
|
program that provides OPIE challenges
|
|
|
|
|
to users and accepts OPIE responses. It is downward compatible with the
|
|
|
|
|
.IR keylogin(1)
|
|
|
|
|
program from the Bellcore S/Key Version 1 distribution, which, in
|
|
|
|
|
turn, is downward compatible with the
|
|
|
|
|
.IR login(1)
|
|
|
|
|
program from the 4.3BSD Net/2 distribution.
|
|
|
|
|
|
|
|
|
|
.SH OPTIONS
|
|
|
|
|
.TP
|
|
|
|
|
.B \-p
|
|
|
|
|
By default, login discards any previous environment. The \-p
|
|
|
|
|
option disables this behavior.
|
|
|
|
|
.TP
|
|
|
|
|
.B \-r
|
|
|
|
|
Process remote login from
|
|
|
|
|
.I hostname.
|
|
|
|
|
.TP
|
|
|
|
|
.B \-h
|
|
|
|
|
The -h option specifies the host from which the connection was
|
|
|
|
|
received. It is used by various daemons such as telnetd(8).
|
|
|
|
|
This option may only be used by the super\-user.
|
|
|
|
|
.TP
|
|
|
|
|
.B \-f
|
|
|
|
|
The -f option is used when a user name is specified to indicate
|
|
|
|
|
that proper authentication has already been done and that no
|
|
|
|
|
password need be requested. This option may only be used by the
|
|
|
|
|
super\-user or when an already logged in user is logging in as
|
|
|
|
|
themselves.
|
|
|
|
|
.TP
|
|
|
|
|
.I username
|
|
|
|
|
The user name to log in as.
