YPPASSWD(1)         RISC/os Reference Manual          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 pass-
     word 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 charac-
     ters 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 Network Information Service password daemon
     yppasswdd(1M) must be running on your NIS server in order
     for the new password to take effect.

     Manual.

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 noti-
     fied until after you have entered your new password.
