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
-Y option)
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 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
-
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 credential, 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.
FILES
- /etc/init.d/rpc
-
