ypchfn
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 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 infor
mation for the invoking user will be updated, otherwise
that of user will be updated. This option is only avail
able 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
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.
