Advanced Python Script SSH problem on probe

Since last Friday (when we installed the last update of PRTG) we are no longer able to run Advanced Python Sensor on a remote probe. The scripts haven't changed and still work on the local probe, but can't find the winrandom module in Python on the remote probe. All python34 files which are on the local server are present on the probe as well. PRTG Network Monitor 18.4.46.1754 x64

Something must have changed but after seaching for 2 days I haven't been able to find the source of the issue. Installed a new remote probe on a new machine and it has the same issue.

Detailed error is

29/01/2019 14:21:29 Script Output (UTF8 Encoding): Traceback (most recent call last):[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\custom sensors\python\ssh_x5_evolution_b927.py", line 3, in <module>[CR][LF]    import paramiko[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\paramiko\__init__.py", line 30, in <module>[CR][LF]    from paramiko.transport import SecurityOptions, Transport[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\paramiko\transport.py", line 49, in <module>[CR][LF]    from paramiko.dsskey import DSSKey[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\paramiko\dsskey.py", line 26, in <module>[CR][LF]    from Crypto.PublicKey import DSA[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\Crypto\PublicKey\DSA.py", line 89, in <module>[CR][LF]    from Crypto import Random[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\Crypto\Random\__init__.py", line 28, in <module>[CR][LF]    from Crypto.Random import OSRNG[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\Crypto\Random\OSRNG\__init__.py", line 34, in <module>[CR][LF]    from Crypto.Random.OSRNG.nt import new[CR][LF]  File "C:\Program Files (x86)\PRTG Network Monitor\Python34\lib\site-packages\Crypto\Random\OSRNG\nt.py", line 28, in <module>[CR][LF]    import winrandom[CR][LF]ImportError: No module named 'winrandom'[CR][LF]

Tried the standard from . import winrandom and some variations on the nt.py file but no success.

Any ideas would be welcome

Thanks Michaël

Did you try to install winrandom via pip? You'll need to install it first in PRTGs Python directory:

  1. Download https://bootstrap.pypa.io/get-pip.py into
  2. Execute the following via administrative command line: python get-pip.py

Good morning Stephan, Thank you for the fast response. I did try to reinstall winrandom with pip on both machines but that resulted in failure (see below in both cases)

Additionally will PRTG update its python version from 3.4 ?

DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it. Please upgrade your Python as Python 3.4 won't be maintained after March 2019 (cf PEP 429).

Kind regards Michaël

Ah, bummer. We do indeed plan to update it as there's a ticket for it, but this will take quite some time I'm afraid. In the meantime, could you use PowerShell and the EXE/Script (Advanced) Sensors to execute python.exe from a different Python installation? That should actually work. Perhaps the returned result needs to be tailored somewhat.

Not exactly the answer I was looking for. Especially that we have been building our application based on the assumption that your platform woudl offer the necessary stability. Back to the drawingboard. :-(^:-(

But you could use the very same python script you already developed? You're just executing it "passively" via PowerShell, instead of using a Python Sensor :)

True, but I would lose all accumulated data for that sensor ... I need to think about the further implications.
