OPIESU(1)OPIESU(1)NAMEopiesu - Replacement su(1) program that uses OPIE
challenges
SYNOPSISopiesu [ -f ] [ -c ] [ user_name ]
DESCRIPTIONopiesu is a replacement for the su(1) program that
issues OPIE challenges and uses OPIE responses. It is
downward compatible with keysu(1) from the Bellcore
S/Key Version 1 distribution and the su(1) program
from the 4.3BSD Net/2 distribution.
OPTIONS-f If the invoked shell is csh(1), this option
prevents it from reading the ``.cshrc'' file.
(The [f] option may be passed as a shell argu‐
ment after the login name, so this option is
redundant and obsolescent.)
-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 cal‐
culator. 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.
user_name
The name of the user to become. The default
is root.
