NAME
       yppasswd, ypchfn, ypchsh - change your password in the NIS database

SYNOPSIS
       yppasswd [-f] [-l] [-p] [user]
       ypchfn [user]
       ypchsh [user]

DESCRIPTION
       The standard passwd(1), chfn(1) and chsh(1) cannot be used under Linux
       to change the users NIS password, shell and GECOS information, because
       they  only  modify  the password file on the local host.	 For changing
       the NIS information, they are  replaced	by  their  NIS	counterparts,
       yppasswd, ypchfn and ypchsh.

       These commands are the same program, linked to different names.	Using
       the command line switches, you can choose whether to update your pass-
       word -p, your login shell -l, or your GECOS field -f, or a combination
       of them.	 yppasswd implies the -p option, if no other option is given.
       If  you	use  the  -f  or -l option, you also need to add the -p flag.
       ypchfn implies the -f option, and ypchsh -l.

       When invoked without the user argument, the  account  information  for
       the  invoking  user  will  be  updated, otherwise that of user will be
       updated. This option is only  available	to  the	 super-user.  If  the
       yppasswdd  daemon  on  the  server  supports it, you can give the root
       password of the server instead of the users [old] password.

       All tools will first prompt the user  for  the  current	NIS  password
       needed  for authentication with the yppasswdd(8) daemon. Subsequently,
       the program prompts for the updated information:

       yppasswd or -l
	      Change the user’s NIS password.	 The user is prompted for the
	      new  password.   While  typing  the password, echoing is turned
	      off, so the password does not appear on the  screen.  An	empty
	      password is rejected, as are passwords shorter than six charac-
	      ters. The user will then be requested to retype the password to
	      make sure it wasn’t     misspelled the first time.

       ypchsh or -l
	      Change  the  user’s login shell. The user is prompted for a new
	      shell, offering the old one as default:

		Login shell [/bin/sh]: _

	      To accept the default, simply press return. To clear the	shell
	      field  in	 your  passwd(5)  file	entry  (so  that the system’s
	      default shell is selected), enter the string none.

       ypchfn or -f
	      Change the user’s full name and related information. Tradition-
	      ally, some applications expect the GECOS field (field 4) of the
	      passwd(5) file to contain the user’s real name (as  opposed  to
	      the  login  name)	 plus  some  additional	 information like the
	      office phone number. This information is displayed by finger(1)
	      and probably some other tools, too.

	      When  setting  the  full	name,  ypchfn  displays the following
	      prompts, with the defaults in brackets:

		Name [Joe Doe]:
		Location [2nd floor, bldg 34]:
		Office Phone [12345]:
		Home Phone []:

	      To accept a default, simply press return.	 To  clear  a  field,
	      enter the string none.
