NAME
rpc.nispasswdd, nispasswdd - NIS] password update daemon
SYNOPSIS
/usr/sbin/rpc.nispasswdd [-a attempts] [-c minutes] [-D]
[-g] [-v]
DESCRIPTION
rpc.nispasswdd daemon is an ONC] RPC service that services
password update requests from nispasswd(1) and yppasswd(1).
It updates password entries in the NIS] passwd table.
rpc.nispasswdd is normally started from a system startup
script after the NIS] server (rpc.nisd(1M)) has been
started. rpc.nispasswdd will determine whether it is running
on a machine that is a master server for one or more NIS]
directories. If it discovers that the host is not a master
server, then it will promptly exit. It will also determine
if rpc.nisd(1M) is running in NIS (YP) compatibility mode
(the -Yoption) and will register as yppasswdd for NIS (YP)
clients as well.
rpc.nispasswdd will syslog all failed password update
attempts, which will allow an administrator to determine
whether someone was trying to "crack" the passwords.
rpc.nispasswdd has to be run by a superuser.
OPTIONS
-a attempts Set the maximum number of attempts allowed to
authenticate the caller within a password
update request session. Failed attempts are
syslogd(1M) and the request is cached by the
daemon. After the maximum number of allowed
attempts the daemon severs the connection to
the client. The default value is set to 3.
-c minutes Set the number of minutes a failed password
update request should be cached by the dae-
mon. This is the time during which if the
daemon receives further password update
requests for the same user and authentication
of the caller fails, then the daemon will
simply not respond. The default value is set
to 30minutes.

System Administration Commands rpc.nispasswdd(1M)
-D Debug. Run in debugging mode.
-g Generate DES credential. By default the DES
credential is not generated for the user if
they do not have one. By specifying this
option, if the user does not have a creden-
tial, then one will be generated for them and
stored in the NIS] cred table.
-v Verbose. With this option, the daemon sends a
running narration of what it is doing to the
syslog daemon. This option is useful for
debugging problems.
EXIT STATUS
0 success
1 an error has occurred.
