OPIELOGIN(1) General Commands Manual OPIELOGIN(1)
opielogin - Replacement for login(1) that issues OPIE challenges.
opielogin [ -p ] [ -r hostname | -h hostname | -f username
| username ]
opielogin provides a replacement for the login(1) program that provides OPIE challenges to users and accepts OPIE responses. It is downward
compatible with the keylogin(1) program from the Bellcore S/Key Version 1 distribution, which, in turn, is downward compatible with the
login(1) program from the 4.3BSD Net/2 distribution.
-p By default, login discards any previous environment. The -p option disables this behavior.
-r Process remote login from hostname.
-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.
-f The -f option is used when a user name is specified to indicate that proper authentication has already been done and that no pass-
word need be requested. This option may only be used by the super-user or when an already logged in user is logging in as them-
The user name to log in as.
