update of asinfo.txt

[aalmenar]

Is there a way to update asinfo.txt located here?

[JackSlateur]

Sure, the asinfo.txt is based on this: https://github.com/manuelkasper/AS-Stats/blob/master/contrib/generate-asinfo.py

However, please note that the fetch_ip_asn.py script does not actually care much about that file
You can proceed this way, to fetch ASN from AS1 to AS2000

for i in {1..2000}; do echo $i; done | ./fetch_ip_asn.py /dev/stdin

I have used the database of https://dev.maxmind.com/geoip/geoip2/geolite2/ in combination with the following:

tail -q -n +2  GeoLite2-ASN-CSV_20190514/GeoLite2-ASN-Blocks-IPv4.csv GeoLite2-ASN-CSV_20190514/GeoLite2-ASN-Blocks-IPv6.csv | jq -n -R '

  inputs |
  split(",") |
  { (.[0]):  .[1] } '  | jq -s add

To get an up to date database.

jq: --null-input cannot be used with --raw-input or --slurp
Use jq --help for help with command-line options,
or see the jq documentation at http://stedolan.github.com/jq
null

Could not start your command string, and the script for i in {1..2000}; do echo $ i; done | ./fetch_ip_asn.py / dev / stdin is frozen.

@ya-zero this has worked for me with
jq-1.5-1-a5b5cbe

good !

when I installed the as-stats system, I found that not all traffic on graphs is displayed.
suggested that a very old asinfo.txt
the next step I updated asinfo. according to your example. everything went well.
but the graphics stubbornly draw less volume

@empi89, your idea is wonderful. MaxMind provides a good database with a compact set of prefixes, reducing the number of items in the JSON file. In addition, it includes only the ASNs that actually exist, not an interval from 1 to N.

To complement your idea, using the newly created ip2as.json, the command below will generate an asinfo.txt.

(echo begin; echo verbose; jq -r 'to_entries | .[].value' ip2as.json | sort -n -u | sed 's/^/AS/'; echo end) | netcat whois.cymru.com 43 | ./generate-asinfo.py > asinfo.txt

Note that this command is just a slight modification of the usage of the original script generate-asinfo.py.
