Cloudfare blocking download of MaxMind GeoIP databases

As described here, Cloudfare sometimes consider an IP address as suspicious and block any automated download of MaxMind databases. There is no easy way to fix that in the code directly but you can download thee files manually with your browser and store them where Harpoon would have :

• http://geolite.maxmind.com/download/geoip/database/GeoLite2-City.tar.gz, untar it and store it in ~/.config/harpoon/GeoLite2-City.mmdb
• http://geolite.maxmind.com/download/geoip/database/GeoLite2-ASN.tar.gz, untar it and stores it in ~/.config/harpoon/GeoLite2-ASN.mmdb

Old maxminddb version

If you get a crash like :

File "/usr/local/lib/python3.6/dist-packages/harpoon-0.1.1-py3.6.egg/harpoon/commands/domain.py", line 8, in <module>
    import geoip2.database
  File "/usr/local/lib/python3.6/dist-packages/geoip2/database.py", line 11, in <module>
    from maxminddb import (MODE_AUTO, MODE_MMAP, MODE_MMAP_EXT, MODE_FILE, MODE_MEMORY, MODE_FD)
ImportError: cannot import name 'MODE_FD'

It means that you are using a version of maxminddb that's too old for geoip, you should update to maxminddb at least 1.4.0, which you can do with pip install maxminddb -U
