I have set up DB Master and proceeded to setting up DB Slave. While copying the DB Master database, the following error is displayed: "Error. (Exception) Warning: Using a password on the command line interface can be insecure. Warning: Using a password on the command line interface can be insecure. mysqldump: Got error: 1045: Access denied for user 'aunet'@'192.168.3.47' (using password: YES) when trying to connect". 192.168.3.47 is the IP address of DB Slave.
The error occurs due to the incorrect reverse DNS and incorrect hostname specified during installation:
while installing the DB Master, the pre-populated aucore.your-router DNS hostname was selected
DB Slave is up and re-registered the aucore host in DHCP/DNS on the router
the pre-populated aucore.your-router DNS hostmane was selected on DB Slave
The pre-populated DNS names cannot be used during the installation. In such case you must enter IP address. DNS hostnames should be specified on the corporate DNS server.
