YPPASSWD(1)							   YPPASSWD(1)


NAME    [Toc]    [Back]

     yppasswd -	change NIS login password

SYNOPSIS    [Toc]    [Back]

     yppasswd [name]

DESCRIPTION    [Toc]    [Back]

     yppasswd changes (or installs) a password associated with the user	name
     (your own name by default)	in the network information service (NIS)
     passwd databases.	The NIS	password may be	different from the one for the
     same user in the local /etc/passwd	file.

     yppasswd prompts for the old NIS password and then	for the	new one.  The
     caller must supply	both.  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.

     Use ypchpass(1) to	change other passwd(4) fields.

SEE ALSO    [Toc]    [Back]

      
      
     passwd(1),	ypchpass(1), ypfiles(4), rpc.passwd(1M)

BUGS    [Toc]    [Back]

     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.
