[BUG] The machine id change caused the license to become a trial version

[zssyqpgdll]

I am using the windows system of a physical device and do not use docker. The machine code change causes the license of the original group version to be changed to the trial version.
How should I solve this problem?

$ pyarmor -d reg pyarmor-device-regfile-6095.1.zip
DEBUG    group license for machines: ['tokens/i6d409f0e5bd1df35ab1c28fe1cb26d86']

Why is there more than one machine id and is there a way to clear the machine id?

[jondy]

For compatible with old Pyarmor versions, there are many machine ids, the first char is version flag of machine id.

What's your Python version and platform (x86_64 or x86)? I'll build a debug version to print more information to check why machine id is changed.

[jondy]

By the way, if there are multiple platforms in one machine, each system should generate its own device file.

Are they same system?

If they're same systems, try to download extension pytransform3 with corresponding Python version. For example, if using Python 3.11

https://pyarmor.dashingsoft.com/downloads/temp/win64/cp3.11/pytransform3.pyd

Next check the output

python3.11
>>> from pytransform3 import get_hd_info
>>> get_hd_info(18)

Then reboot machine, and run the above commands and check output.

Compare the output, and report what's changed.

I'm using windows x86_64, python version 3.7.13.
All actions are implemented in one machine, one platform.

[jondy]

If they're same systems, try to download extension with corresponding Python version. For example, if using Python 3.7
https://pyarmor.dashingsoft.com/downloads/temp/win64/cp3.7/pytransform3.pyd

Next check the output

    python3.7                                                       
    >>> from pytransform3 import get_hd_info                         
    >>> get_hd_info(18)                                              

Then reboot machine, and run the above commands and check output.

Compare the output, and report what's changed.

[zssyqpgdll]

After using the extension pack, the id still changed after the reboot, and my license became the trial version again.

`>>> from pyarmor.cli.core.pytransform3 import get_hd_info

print(get_hd_info(18))`

pre:
b'i1c954ce0b7c2948d7d9e26b770a64d23'
after reboot:
b'i41b1f5b538782f9ebcf4ec8e90a8d8e4'

[zssyqpgdll]

How to do? I can't activate a new license every time I reboot the device, and the license has a limit on the number of offline devices.

[jondy]

Could you report what're changed of the hardware information?

If you use the downloaded pytransform3.pyd, it should print more information.

[jondy]

Please do not paste snapshot image, it's better to paste text directly.

[zssyqpgdll]

I did print some more information when I used the downloaded pytransform3.pyd, but the printed information was confusing.

`

from pyarmor.cli.core.pytransform3 import get_hd_info
print(get_hd_info(18))

[jondy]

It doesn't matter, just paste the output. But at least twice for 2 different machine id

[jondy]

I need check which hardware information is changed by comparing the output log.

This is a bug, I have found the problem. It will be fixed in next release v8.3.8

[jondy]

Fixed in v8.3.8, note that it need generate new device file for this device by Pyarmor 8.3.8

[jondy]

@BenjaminYde
Please upgrade Pyarmor to the latest v8.3.8, it fix a group license reboot doesn't work issue (if there are multiple network cards).

Note that it need generate new device file for this device by Pyarmor 8.3.8

[BenjaminYde]

@jondy, tested with pyarmor 8.3.8 with reboot. Seems to be fixed now. Thanks! 👍

Did the following

pip install pyarmor==8.3.8
pyarmor --version

Did the following twice (with reboot in between)

pyarmor reg -g 5
pyarmor reg -g 5 ./pyarmor-regfile-6054.zip
cat .pyarmor/group/pyarmor-group-device.5

pyarmor reg ./pyarmor-device-regfile-6054.5.zip
pyarmor-auth pyarmor-device-regfile-6054.5.zip

[BenjaminYde]

@jondy, Now I have another problem. using pyarmor 8.3.8
It is not possible to register inside the container using the device-regfile.

Step 1: Start the pyarmor-auth on the host:

pyarmor-auth pyarmor-device-regfile-6054.5.zip

Works fine.

Step 2: Activate pyarmor using the device regfile in the container:

• copied pyarmor-group-device in container
• copied pyarmor-device-regfile in container
• activate pyarmor using regfile:

pyarmor reg pyarmor-device-regfile-6054.5.zip

This gives the following error:

INFO     Python 3.10.6
INFO     Pyarmor 8.3.8 (trial), 000000, non-profits
INFO     Platform linux.x86_64

As you can see on the following picture, the request was received (from container >> host) and send back (host >> container):

Here a diagram I made :) :
Can help people to understand.

@BenjaminYde

Please upgrade Pyarmor to 8.3.9, the newest flag is missed in 8.3.8

[BenjaminYde]

@jondy, tested with pip install pyarmor==8.3.9

• Now i can register inside the docker container. It prints everything about the license being successfully activated.
• But now i have the problem that when i run an obfuscation command, the pyarmor-auth server on the host is complaining about the license not being valid?

On the host (pyarmor-auth):

In the container (register regfile):

In the container (obfuscate pacakge):

• The pyarmor license automatically changes to trail version after license failure.

On the host (pyarmor-auth):

[BenjaminYde]

pyarmor 8.3.9 is released on pypi.org but no release has been made on this repo

[jondy]

@BenjaminYde

It changed a little, so it did not released in github.com

[BenjaminYde]

@jondy, do you have an idea when this would be fixed?
We want to use pyarmor group license for months but cannot because of the license issues.
We really look forward to using it.

[jondy]

@BenjaminYde

Please check #1511, maybe they're same issue. I'm researching this.

BTW, it's better to paste the log text instead image, because github cli could not show image.

[jondy]

@BenjaminYde

Sorry, it should check #1502, not 1511

[BenjaminYde]

Just curious, are there any more updates on this @jondy?

[jondy]

@BenjaminYde

Please upgrade Pyarmor to 8.4.0, and generate new device file by 8.4.0

Make sure machine id could keep same

[jondy]

@BenjaminYde

Please check issue #1542, it need extra settings if docker host is Windows or MacOS.
