Compatibility with maxmind datasets about mmdbctl HOT 10 CLOSED

Thank you @ingria for reporting. Will look into it soon!

from mmdbctl.

We're going to implement this very soon, within a week or two. No worries!

from mmdbctl.

This is likely because of #2 - the geolite2/geoip2 datasets have nested structures which we don't yet support properly.

from mmdbctl.

Also it would be nice to be able to use ipinfo mmdbs as a drop-in replacement for maxmind datasets (I assume that they are generated with mmdbctl). The problem is that many existing services only supports the native “nested” structure.

e.g. https://docs.nginx.com/nginx/admin-guide/dynamic-modules/geoip2/

from mmdbctl.

I realize you may not care as you sell your own, but can your tool verify the integrity of those dbs with nested structures such as mm's? That'd already be useful to make automation more robust in case of corrupted downloads.

Tried with one, and while lookups and metadata are broken as expected, after randomly changing a byte, the verify indeed recognizes it and fails.

from mmdbctl.

This is fixed - can anyone here who was looking for this use case check and provide feedback?

from mmdbctl.

I can confirm that maxmind dbs are now readable 👍

Is it possible to write nested structured datat into mmdb with mmdbctl?

from mmdbctl.

@ingria Yes, if you have a JSON file with nested structures, it'll be written as a natively nested structure in the MMDB file too.

Lemme know if you face any issues, happy to debug.

Understood, thanks!

Sorry if I'm missing something obvious. I try to import from .json (with nested structures) to .mmdb. It gives me such errors:

panic: interface conversion: interface {} is []interface {}, not map[string]interface {}

goroutine 1 [running]:
github.com/ipinfo/mmdbctl/lib.CmdImport({0x0, {0x7ffdcd4baed2, 0x14}, {0x7ffdcd4baeed, 0x1c}, 0x0, 0x0, 0x0, {0x0, 0x0, ...}, ...}, ...)

Unfortunately, i don't know Go language and cannot understand this issue. Can anyone explain what I do wrong? JSON that I use looks like this:

[
  {
    "range": "10.0.1.0/24",
    "continent": {
      "geoname_id": 6255000
    },
    "country": {
      "geoname_id": 2017000
    },
    "subdivisions": [
      {
        "geoname_id": 536000
      }
    ],
    "city": {
      "geoname_id": 498000
    },
    "location": {
      "latitude": 63,
      "longitude": 28,
      "accuracy_radius": 5
    }
  },
  {
    "range": "10.0.3.0/25",
    "continent": {
      "geoname_id": 6255000
    },
    "country": {
      "geoname_id": 2017000
    },
    "subdivisions": [
      {
        "geoname_id": 1488000
      }
    ],
    "city": {
      "geoname_id": 1488000
    },
    "location": {
      "latitude": 45,
      "longitude": 55,
      "accuracy_radius": 1
    }
  },
  {
    "range": "10.0.3.128/25",
    "continent": {
      "geoname_id": 6255000
    },
    "country": {
      "geoname_id": 2017000
    },
    "subdivisions": [
      {
        "geoname_id": 1488000
      }
    ],
    "city": {
      "geoname_id": 1488000
    },
    "location": {
      "latitude": 52,
      "longitude": 62,
      "accuracy_radius": 1
    }
  }
]

And import cmd is the following:

mmdbctl import --in to-import-geoip.json --out imported-from-json-geoip.mmdb

from mmdbctl.
