YPPASSWD(1)             COMMAND REFERENCE             YPPASSWD(1)



NAME
     yppasswd - change login password in Yellow Pages

SYNOPSIS
     yppasswd [ name ]

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

     The yppasswd command prompts for the old Yellow Pages
     password, then prompts for the new one; you must type 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 they must be 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 Yellow Pages password daemon, rpc.yppasswdd(8c) must be
     running on your YP server in order for the new password to
     take effect.

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