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.
- -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.
- success
- an error has occurred.
