gvm.errors.GvmError: Socket /var/run/gvmd.sock does not exist

a.sarritzu · January 10, 2020, 1:30pm

Hello,

I’ve installed the gvm-tools (with pip3) but when I try to run the gvm-pyshell in socket mode I get this error:

gvm.errors.GvmError: Socket /var/run/gvmd.sock does not exist

Any hint about how to fix it?

"/opt/gvm/.local/bin/gvm-pyshell", line 10, in <module> sys.exit(main()) File "/opt/gvm/.local/lib/python3.7/site-packages/gvmtools/pyshell.py", line 134, in main with protocol_class(connection, transform=transform) as protocol: File "/opt/gvm/.local/lib/python3.7/site-packages/gvm/protocols/gmp.py", line 79, in __enter__ self.connect() File "/opt/gvm/.local/lib/python3.7/site-packages/gvm/protocols/base.py", line 107, in connect self._connection.connect() File "/opt/gvm/.local/lib/python3.7/site-packages/gvm/connections.py", line 353, in connect ) from None gvm.errors.GvmError: Socket /var/run/gvmd.sock does not exist

There is no gvmd.sock in the whole system. I can only see the ospd.sock:

It seems gvmd is running in some way:

Did you check other locations? it depends on your installation (check: https://readthedocs.org/projects/gvm-tools/downloads/pdf/latest/). Is your manager up and running?

a.sarritzu · January 14, 2020, 2:53pm

Yes it’s up and running. There is something I don’t understand: When is usually the socket created? During the installation? Or When the process starts?

warschauer · January 14, 2020, 3:14pm

My understanding is that the manager is responsible for creating it, depending on whether you use unix socket or tls authentication.

Where the socket is created depends on your build parameters and settings for gvmd. If you want to adjust the socket location you can use

-c, --unix-socket=<filename>                  Listen on UNIX socket at <filename>.

The unix socket is created by gvmd after startup automatically.

Vane · January 29, 2020, 4:26pm

Hello, same issue here.
I can communicate using osp (ospd.sock does exist) but gvmd.sock doesn’t exist.
I tried touch gvmd.sock , then chmod 777 gmvd.sock and i got a Errno 111 ( i know its not the proper way to do it ) any info will be appriciated

regards

bricks · January 30, 2020, 7:52am

The path to the gvmd socket depends on your installation method. If you got gvmd via packages it should be placed under /var/run/gvmd.sock. gvmd will create the socket at startup if it isn’t configured to use TLS connections. If you need different socket settings e.g. different path or permissions please take a look at the parameters shown with --help and adjust your startup configurations. These configurations are distribution and package specific. Most of the time systemd service files are used.

Vane · January 30, 2020, 9:43am

Thanks for the fast reply!.
I’m using this one https://github.com/Secure-Compliance-Solutions-LLC/GVM-Docker
and i have tried either dockerized and not(with some script adjusting).
From my understanding since i’m a newbie i cant use osp protocol to initiate scans through python-scripting yet, therefore i need to use gvmd.sock to use the GMP protocol
Through the docker container i can detect gvmd.sock , but at /tmp only ospd.sock exists && and its not in /var/run either.

I really don’t have a clue about the docker instance. Please ask the maintainers for further information.

Vane · January 30, 2020, 10:02am

i see,
i am correct about not trying to initiate a scan using OSP protocol rather than GMP right?
thank you for your time!

bricks · January 30, 2020, 10:07am

OSP is the protocol used between gvmd and osp scanner especially ospd-openvas. gvmd stores, manages and evaluates the data provided by the scanners via OSP. GMP is the protocol used as our public API and also between gsad and gvmd. So this depends on your use case.

a.sarritzu · January 30, 2020, 10:17am

This is what I was missing!
I wasn’t able to find the socket because TLS connection was configured!
Thank you very very much!
