yppasswd(1)			     General Commands Manual			      yppasswd(1)

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 counter-
       parts, 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 password -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 pass-
       word of the server instead of the users [old] password.

       All  tools  will first prompt the user for the current NIS password needed for authentica-
       tion 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
	      characters. 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. Traditionally,  some  applica-
	      tions  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.
