See the mod_geoip2.html documentation for more details.

proftpd-mod_geoip2's Issues

Add client IP address, username to GeoIPLog

Hi. Thanks for the GeoIP2 module. No issue, however a request.

Currently, the GeoIPLog is working fine and output is minimal info, ie:
2022-03-12 20:13:26,960 mod_geoip2/0.1[53605]: CountryCode filter value 'XX' matched GeoIPAllowFilter pattern 'XX'
2022-03-12 20:13:27,108 mod_geoip2/0.1[53605]: CountryCode filter value 'XX' matched GeoIPAllowFilter pattern 'XX'

The request is as follows:
1. To add the Source IP address into the above line - %a
2. To add the User Name into the above line - %u

ex:
    2022-03-12 20:13:27,108 mod_geoip2/0.1[53605]: [Client IP Address - %a] [User Name - %u] CountryCode filter value 'XX' matched GeoIPAllowFilter pattern 'XX'

    2022-03-12 20:55:57,218 mod_geoip2/0.1[73498]: connection from 219.100.37.239, Username: %u denied due to GeoIP filter/policy
    2022-03-12 20:56:03,974 mod_geoip2/0.1[73499]: CountryCode filter value 'JP' did not match GeoIPAllowFilter pattern 'XX'

Thanks and regards

Alpine build with libmaxminddb

Trying to build this on Alpine 3.10 in Docker. I can build when including the older GeoIP library, but just using libmaxminddb-dev and libmaxminddb without geoip causes the error below:
