NAME

yppasswd - change login password in yellow pages

SYNOPSIS

yppasswd [ name ]

DESCRIPTION

Yppasswd changes (or installs) a network password associated with the user name (your own name by default) in the yellow pages. The yellow pages password may be different from the one on your own machine.

Yppasswd prompts for the old yellow pages 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 yellow-pages password daemon, yppasswdd(8C) must be running on your YP server in order for the new password to take effect.

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 password.
