NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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  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 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 -p
	      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 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.
