Description
The feature of CountryFilter is as follows.
- This script can display country name by finding the country from IP-address of the player.
- This script provides access control (allow/deny) based on player country name.
- This script uses GeoIP Free Country, and its accuracy of conversion is approximately 97%.

# http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
#
#
# Install:
#
# - Copy CountryFilter.py and PurePythonGeoIP.py to
# '<bf2>/Admin/standard_admin' directory.
#
# - Add the lines 'import CountryFilter' and 'CountryFilter.init()'
# to the file '<bf2>/admin/standard_admin/__init__.py'.
#
# ex.)
# import autobalance
# import tk_punish
# import CountryFilter
#
# autobalance.init()
# tk_punish.init()
# CountryFilter.init()
#
# - Download GeoIP.dat from
# http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz
# and extract it.
#
# - Copy GeoIP.dat to '<bf2>' directory.
#
# - Finally, it must be the following.
#
# ex.)
# <bf2>/Admin/standard_admin/CountryFilter.py
# <bf2>/Admin/standard_admin/PurePythonGeoIP.py
# <bf2>/GeoIP.dat
#

# http://d3.jpn.org/hl2/CountryFilter-jp.html (Japanese)
#
# - You can customize the print format of country.
#
# - Country code by two characters. ex.) JP
#
cf_country_print_mode = 'code'
#
# - Country code by three characters. ex.) JPN
#
#cf_country_print_mode = 'code3'
#
# - Long country name. ex.) Japan
#
#cf_country_print_mode = 'name'
#
# - You can customize the message format when script allow/deny the
# connection according to the country of the player.
#
# - Message format when player was allowed to connect.
# %(name)s is replaced with player name.
# %(country)s is replaced with country name.
# The message will not displayed when setting as
# cf_allow_message = ''.
#
cf_allow_message = '%(name)s (Country: %(country)s) was allowed to connect.'
#
# - Message format when player was denied to connect.
# %(name)s is replaced with player name.
# %(country)s is replaced with country name.
# The message will not displayed when setting as
# cf_deny_message = ''.
#
cf_deny_message = '%(name)s (Country: %(country)s) was rejected by CountryFilter.'
#
# - Specify the country(s) which is excluded from printing
# messages.
# Available value is same as cf_allow_from and cf_deny_from.
#
cf_message_exclude_from = ''
#
# - Allowing/denying the connection according to the country of the
# player.
#
# You can limit the connection by using cf_allow_from,
# cf_deny_from, and cf_order. Please specify this by the country
# code of two characters. Basically, it is the same as the
# mod_access module of Apache. See this URL.
#
# http://httpd.apache.org/docs/mod/mod_access.html
#
# - cf_allow_from
#
# cf_allow_from specify the country(s) which is allowed to
# connect. Available value of cf_allow_from is 'all', '', '--'
# and country code by 2 characters. If you want to specify
# multiple value, use space as delimiter. Set 'all', if you want
# to allow all countries. When '' (null string) is specified,
# nothing is done. '--' is unknown country. Note: when you
# connect to server from LAN, its IP-address is 192.168.xxx.xxx,
# so this script cannot find valid country name. Therefore if
# you want to allow to connect from LAN, you must specify '--'.
#
# ex.1)
# # Allowing all countries.
# cf_allow_from = 'all'
#
# ex.2)
# # Allowing only JP, US and LAN.
# cf_allow_from = 'JP US --'
#
# ex.3)
# # Doing nothing.
# cf_allow_from = ''
#
# - cf_deny_from
#
# cf_deny_from specify the country(s) which is deny to
# connect. Available value of cf_deny_from is quite the same as
# cf_allow_from.
#
# - cf_order
#
# cf_order controls the default access state and the order in
# which cf_allow_from and cf_deny_from are evaluated. The value
# of cf_order must be "deny,allow" or "allow,deny". The default
# value is "deny,allow".
#
# ex.1)
# # It is evaluated in order of deny and allow.
# # Access is allowed by default.
# cf_order = 'deny,allow'
#
# ex.2)
# # It is evaluated in order of allow and deny.
# # Access is denied by default.
# cf_order = 'allow,deny'
#
# - Examples
#
# Some typical usages are shown as follows.
#
# - Allowing all countries. (default)
#
cf_order = 'deny,allow'
cf_deny_from = ''
cf_allow_from = 'all'
#
# - Allowing only JP, US and LAN. Others are denied.
#
#cf_order = 'deny,allow'
#cf_deny_from = 'all'
#cf_allow_from = 'JP US --'
#
# - Denying only JP. Others are allowed.
#
#cf_order = 'allow,deny'
#cf_allow_from = 'all'
#cf_deny_from = 'JP'
#
# If you want to find country code, refer this page.
# http://www.maxmind.com/app/iso3166
#
# - Specify the path of GeoIP.dat file. Default path is
# <bf2>/GeoIP.dat.
#
cf_geoipdat_path = 'GeoIP.dat'
