GvmError: Remove closed the connection

[micycle]

I am trying to run a simple script using the python-gvm library from a windows machine to connect to my Breenbone Security Manager on another machine.
The script goes like this:

from gvm.connections import SSHConnection
from gvm.protocols.gmp import Gmp
from gvm.transforms import EtreeTransform

connection = SSHConnection(hostname=<HOSTNAME>, username=<ADMIN>, password=<PASSWORD>)
transform = EtreeTransform()

with Gmp(connection, transform=transform) as gmp:
    # Retrieve GMP version supported by the remote daemon
    version = gmp.get_version()

But I keep getting the same error, which I can’t understand why is popping up:

GvmError                                  Traceback (most recent call last)

GvmError: Remote closed the connection

What could cause this issue?

GVM versions

Wasn’t sure to which each of those fields refer to, but the version of python-gvm I downloaded from pip was 21.1.3 and the version of the Greenbone OS is 20.08.7
I hope this is OK.

Environment

The Environment that runs the script is a windows 10 and the Greenbone Security Manager runs on a Greenbone OS 20.08.7

Hi, it would be easier to use a gmp script and run it via gvm-tools. gvm-tools already provides and implements the correct connection handling. If you have a GSM just use the defaults to create the SSHConnection. Don’t pass any parameters to the constructor of that class besides the hostname.

[micycle]

I gave it a shot, writing the following script:

def main(gmp, args):
    version = gmp.get_version()


if __name__ == '__gmp__':
    main(gmp, args) 

and then running:
gvm-script ssh --hostname C:\Users\user\AppData\Roaming\JetBrains\PyCharmCE2020.2\scratches\greenbone.py

But what I get is:
SSH Connection failed

[bricks]

Did you activate GMP in the GOS menu?

https://docs.greenbone.net/GSM-Manual/gos-20.08/en/managing-gos.html#configuring-the-greenbone-management-protocol-gmp

The SSH access is not available in the GSM Trial.

[micycle]

I see, I am using the GSM Trial, if so, is there another way to send automated commands to the GSM in the free trial?

[bricks]

No. You can only run GMP scripts on the GSM Trial directly.

Hello @jcordoba and welcome to this community forums.

Please try to use the English language in this forums for any questions / support / help. As your question seems to be also about the Docker Containers i would suggest to look into Community Containers - Greenbone Community Forum for possible existing threads or create a new topic there rather then asking in a 3 year old and already marked as “solved” thread.
