segmentation fault about f2k

[Bigomby]

This issue seems to be an invalid database file. Can you post the content of the config_basic.json file?

config is:

{
        "sensors_networks": {
                "10.211.28.227":{
                        "observations_id": {
                                "16777224":{
                                        "enrichment":{
                                                "sensor_ip":"10.211.28.227",
                                                "sensor_name":"flow_test",
                                                "observation_id":16777224
                                        }
                                },

                                        "enrichment":{
                                                "sensor_ip":"10.211.28.227",
                                                "sensor_name":"flow_test",
                                                "observation_id":16777248
                                        }
                                },
                                "16777240":{
                                        "enrichment":{
                                                "sensor_ip":"10.211.28.227",
                                                "sensor_name":"flow_test",
                                                "observation_id":16777240
                                        }
                                }
                        }
                }
        }
}

this does not explain why f2k will actually run after trying a few times. makes me think of a race condition....but that is just a guess.

I can't reproduce this issue. I tried your configuration and no segfault is produced. Maybe the problem is due to a different library version. There is an available a docker image which contains all the required dependencies with the correct versions.

You can take a look to the Dockerfile or use the image available on Docker Hub.

Using f2k with Docker:

• Clone the repo and cd to the project folder
• The following command will open a shell inside the container:

docker run -it --rm -v $(pwd):/app redborder/dev-containers:f2k

• Compile with ./cofigure and make
• Run f2k

something that might be different is that the netflow packets are send continuously while f2k attempts to startup. not sure if that will have an impact?

will try the docker instance. thank you for the tip.
