YPPASSWD(1)							   YPPASSWD(1)

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.

SEE ALSO
       passwd(1), ypfiles(5), yppasswdd(8C)

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.
