Activating the GMP Protocol?

Building from Source and Advanced Topics Greenbone Management Protocol (GMP)

I want to access the OpenVAS server from another server via gvm-cli.

gvm-cli ssh --gmp-username admin --gmp-password passwd --hostname 192.168.xx.yy --xml “<get_version/>”

Traceback (most recent call last):

In the manual, I found the hint that gmp must first be activated in order to use it over the network. https://docs.greenbone.net/GSM-Manual/gos-4/en/omp.html?highlight=gvm

The above error message does not necessarily fit, but still my question

How can I activate the GMP protocol in the Source Edition?

Hi,

to be able to debug issues it is always necessary to know the exact version of the tools you are using. In this case could you please paste the output of gvm-cli --version?

From the traceback it’s very likely you just hit https://github.com/greenbone/gvm-tools/issues/182

3

gvm-cli --version

gvm-cli 2.0.0b1 (API version 1.0.0.beta2)

4

You are using a non released version from the master branch. Therefore you might always expect broken and unexpected behavior. But nevertheless it is definitively https://github.com/greenbone/gvm-tools/issues/182

Of course you are right, had overlooked the note. I’m sorry about it.
Next try, other mistake.

  1. Authentication failed
  2. SSH Connection failed

# gvm-cli --gmp-username admin --gmp-password passwd ssh --hostname 192.168.xx.yy --xml '<get_version/>'

During handling of the above exception, another exception occurred:

raise GvmError(‘SSH Connection failed’, e)
gvm.errors.GvmError: (‘SSH Connection failed’, AuthenticationException(‘Authentication failed.’,))

That error is very clear. It wasn’t possible to authenticate with your username/password combination.

Getting back on this. Easiest solution is to run gvm-tools on the same host via unix domain socket connection type. Otherwise you have to setup TLS or SSH.

7

For my scenario, it is better if the gvm tools run on a different Computer.

Is there a manual to set up the communication via ssh or tls?
