YPPASSWD(NC) System V NFS (12/3/90) YPPASSWD(NC)
NAME
yppasswd - change login password in network information
service
SYNOPSIS
yppasswd [ name ]
DESCRIPTION
yppasswd changes (or installs) a password associated with
the user name (your own name by default) in the network
information service. The network information service
password may be different from the one on your own machine.
yppasswd prompts for the old network information service
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.
SEE ALSO
passwd(C), ypfiles(NF), yppasswdd(NADM)
BUGS
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.
