NIS+ password update daemon.
/usr/sbin/rpc.nispasswdd [ [ -a Attempts ] [ -c Minutes ] [ -D ] [
-g ] [ -v ]
The rpc.nispasswdd daemon is an ONC+ RPC service that
services password update requests from nispasswd and
yppasswd. It updates password entries in the NIS+
passwd table.
The rpc.nispasswdd daemon is normally started from a
system startup script after the NIS+ server, rpc.nisd has been started.
rpc.nispasswdd determines 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 promptly exits.
It also determines if rpc.nisd is running in NIS(YP)
compatibility mode (the -Y flag and registers as
yppasswdd for NIS(YP) clients as well.
The rpc.nispasswdd daemon will syslog all failed password
update attempts, which allows an administrator to determine whether someone
was trying to "crack" the passwords.
rpc.nispasswdd has to be run by a superuser.
| -a
Attempts
| Sets the maximum number of attempts allowed to authenticate the caller
within a password update request session. Failed attempts are
syslogd 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
| Sets the number of minutes a failed password update request should be
cached by the daemon. 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 30 minutes.
|
| -D
| Runs in debugging mode.
|
| -g
| Generates DES credential. By default the DES credential is not
generated for the user if they do not have one. By specifying this
flag, if the user does not have a credential, then one will be generated for
them and stored in the NIS+ cred table.
|
| -v
| Sets verbose mode. With this flag, the daemon sends a running
narration of what it is doing to the syslog daemon. This flag is useful
for debugging problems.
|
| 0
| Success
|
| 1
| An error has occurred.
