- Use a script to replace "A1" ("Anonymous Proxy") entries in our

geoip file with real country codes. This script fixes about 90% of

"A1" entries automatically and uses manual country code assignments
|

to fix the remaining 10%. See src/config/README.geoip for details.

Fixes #6266.

README.geoip -- information on the IP-to-country-code file shipped with tor
|
||||
===========================================================================
|
||||
|
||||
The IP-to-country-code file in src/config/geoip is based on MaxMind's
|
||||
GeoLite Country database with the following modifications:
|
||||
|
||||
- Those "A1" ("Anonymous Proxy") entries lying inbetween two entries with
|
||||
the same country code are automatically changed to that country code.
|
||||
These changes can be overriden by specifying a different country code
|
||||
in src/config/geoip-manual.
|
||||
|
||||
- Other "A1" entries are replaced with country codes specified in
|
||||
src/config/geoip-manual, or are left as is if there is no corresponding
|
||||
entry in that file. Even non-"A1" entries can be modified by adding a
|
||||
replacement entry to src/config/geoip-manual. Handle with care.
|
||||
|
||||
|
||||
1. Updating the geoip file from a MaxMind database file
|
||||
-------------------------------------------------------
|
||||
|
||||
Download the most recent MaxMind GeoLite Country database:
|
||||
http://geolite.maxmind.com/download/geoip/database/GeoIPCountryCSV.zip
|
||||
|
||||
Run `python deanonymind.py` in the local directory. Review the output to
|
||||
learn about applied automatic/manual changes and watch out for any
|
||||
warnings.
|
||||
|
||||
Possibly edit geoip-manual to make more/fewer/different manual changes and
|
||||
re-run `python deanonymind.py`.
|
||||
|
||||
When done, prepend the new geoip file with a comment like this:
|
||||
|
||||
# Last updated based on $DATE Maxmind GeoLite Country
|
||||
# See README.geoip for details on the conversion.
|
||||
|
||||
|
||||
2. Verifying automatic and manual changes using diff
|
||||
----------------------------------------------------
|
||||
|
||||
To unzip the original MaxMind file and look at the automatic changes, run:
|
||||
|
||||
unzip GeoIPCountryCSV.zip
|
||||
diff -U1 GeoIPCountryWhois.csv AutomaticGeoIPCountryWhois.csv
|
||||
|
||||
To look at subsequent manual changes, run:
|
||||
|
||||
diff -U1 AutomaticGeoIPCountryWhois.csv ManualGeoIPCountryWhois.csv
|
||||
|
||||
To manually generate the geoip file and compare it to the automatically
|
||||
created one, run:
|
||||
|
||||
cut -d, -f3-5 < ManualGeoIPCountryWhois.csv | sed 's/"//g' > mygeoip
|
||||
diff -U1 geoip mygeoip
|
||||
|
||||
|
||||
3. Verifying automatic and manual changes using blockfinder
|
||||
-----------------------------------------------------------
|
||||
|
||||
Blockfinder is a powerful tool to handle multiple IP-to-country data
|
||||
sources. Blockfinder has a function to specify a country code and compare
|
||||
conflicting country code assignments in different data sources.
|
||||
|
||||
We can use blockfinder to compare A1 entries in the original MaxMind file
|
||||
with the same or overlapping blocks in the file generated above and in the
|
||||
RIR delegation files:
|
||||
|
||||
git clone https://github.com/ioerror/blockfinder
|
||||
cd blockfinder/
|
||||
python blockfinder -i
|
||||
python blockfinder -r ../GeoIPCountryWhois.csv
|
||||
python blockfinder -r ../ManualGeoIPCountryWhois.csv
|
||||
python blockfinder -p A1 > A1-comparison.txt
|
||||
|
||||
The output marks conflicts between assignments using either '*' in case of
|
||||
two different opinions or '#' for three or more different opinions about
|
||||
the country code for a given block.
|
||||
|
||||
The '*' conflicts are most likely harmless, because there will always be
|
||||
at least two opinions with the original MaxMind file saying A1 and the
|
||||
other two sources saying something more meaningful.
|
||||
|
||||
However, watch out for '#' conflicts. In these cases, the original
|
||||
MaxMind file ("A1"), the updated MaxMind file (hopefully the correct
|
||||
country code), and the RIR delegation files (some other country code) all
|
||||
disagree.
|
||||
|
||||
There are perfectly valid cases where the updated MaxMind file and the RIR
|
||||
delegation files don't agree. But each of those cases must be verified
|
||||
manually.
