Sorry for not specify my question. You are right.
I have two servers. One will be primary and the other secondary.
Both have installed CentOS 5.4 and Bind.
The primary is working. It respondes to queries and already have some dns zones "working on it".
So, the question I want to make in the first post was: how to configure secondary (and primary if needed) to automatically get the dns zones from the primary?
What configurations I have to make? And which servers?
I read some websites that say that allow-transfer is needed. But I'm pretty sure that this is not enough.
I already check that the rndc.key is the same in both server, too.
Many websites talk about this, but none says especifically how to implement this configuration. And because primary is already running, I don't want to make "experiences".
Maybe, I will have to try this in a VMWare.
Anyway, if someone could give me some guidance, I appreciate.

mpscnnsubtractgradient
MPSCNNSubtractGradient(3) MetalPerformanceShaders.framework MPSCNNSubtractGradient(3)
NAME
MPSCNNSubtractGradient
SYNOPSIS
#import <MPSCNNMath.h>
Inherits MPSCNNArithmeticGradient.
Instance Methods
(nonnull instancetype) - initWithDevice:
Additional Inherited Members
Detailed Description
This depends on Metal.framework. Specifies the subtraction gradient operator. This arithmetic gradient filter requires the following
inputs: gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward
pass. You will need a separate filter for the primary and secondary source images.
Without broadcasting, the arithmetic subtract gradient operation for the primary source image is a copy operation on the input gradient
image (for x - y, d/dx(x - y) = 1). This copy operation can be optimized away by the graph interface.
For the secondary source image, the result is a negation of the gradient image from the previous layer (for x - y, d/dy(x - y) = -1).
Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows,
columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary
input images used in the forward pass.
Method Documentation
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
Initialize the subtraction gradient operator.
Parameters:
device The device the filter will run on.
Returns:
A valid MPSCNNSubtractGradient object or nil, if failure.
Reimplemented from MPSCNNArithmeticGradient.
