YPPASSWD(1) MachTen Programmer’s Manual YPPASSWD(1)

NAME
yppasswd - change your network password in the NIS
database

SYNOPSIS
yppasswd [ username ]

DESCRIPTION
yppasswd changes (or installs) the network password asso-
ciated with the user username (your own name by default)
in the Network Information Service (NIS) database. The
NIS password may be different from the local one on your
own machine. See passwd(1).

yppasswd prompts for the old NIS password, and then for
the new one. You must type in the old password correctly
for the change to take effect. The new password must be
typed twice, to forestall mistakes.

New passwords must be at least four characters long, if
they use a sufficiently rich alphabet, and at least six
characters long if monocase. These rules are relaxed if
you are insistent enough. Only the owner of the name or
the super-user may change a password; in either case you
must prove you know the old password.

The NIS password daemon, yppasswdd must be running on your
NIS server in order for the new password to take effect.

SEE ALSO
passwd(1), ypfiles(5),

BUGS
The update protocol passes all the information to the
server in one RPC call, without ever looking at it. Thus
if you type in your old password incorrectly, you will not
be notified until after you have entered your new pass-
word.

NOTES
The Network Information Service (NIS) was formerly known
as Yellow Pages (YP). The functionality of the two
remains the same; only the name has changed. The name
Yellow Pages is a registered trademark in the United King-
dom of British Telecommunications plc, and may not be used
without permission.
