yppasswd(1)                     ONC 5.4R3.00                     yppasswd(1)


NAME
       yppasswd - change your network password in the Network Information
       Service

SYNOPSIS
       yppasswd [ name ]

DESCRIPTION
       yppasswd changes (or installs) a network password associated with the
       user name (your own name by default) in the Network Information
       Service.  The Network Information Service password may be different
       from the one on your own machine.

       yppasswd prompts for the old Network Information Service 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 superuser may change a password; in
       either case you must prove you know the old password.

       The Network Information Service password server, yppasswdd(1M) must
       be running on the master NIS server in order for the new password to
       take effect.

       NOTE:  Secure RPC using DES Authentication is an additional feature
              that must be purchased separately from the DG/UX (Trademark)
              ONC (Trademark)/NFS® package.

       If Secure RPC is installed, yppasswd(1) updates the public/secret key
       pair in the public key database and returns a message indicating that
       the public key database has been updated.

SEE ALSO
       passwd(1), yppasswdd(1M), ypfiles(4).

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.
