Requirements

• bgpscanner
• ipmininet from https://ipmininet.readthedocs.io/en/latest/install.html
• everything else should be in requirements.txt

Instructions

• BGP analysis

  • automatic_attribute_extractor.py takes as input a directory (e.g., the UPDATES directory from a bgp collector), the name of the output file and a list of attributes it should ignore - creates a files where it writes all the attributes it found
  • community-checker.py takes a path (e.g., UPDATES dir from a bgp collector) and a suffix (for naming the output file) and creates a file containing the found Color Extended Communities
  • pipeline for extracting information presented in Table 1:
    • community_csv_creator.py takes a path (e.g., UPDATES dir from bgp collector) and a suffix (for naming the output) -> should be called twice: once with --suspects and the second time with --suspects --no-suspects (needs a suspect-ases.json) -> creates two csvs (the two terms for the set difference regarding suspects):

    python3 community_csv_creator.py --path path/to/rv2/month/UPDATES/ --suspects --suffix rv2 --checkpoints
    python3 community_csv_creator.py --path path/to/rv2/month/UPDATES/ --suspects --no_suspects --suffix rv2 --checkpoints
    

    • suspect-as-aggregator.py takes a suffix for knowing which file to process, prints how many communities appear in the set difference and how many of them appear for more than 1 AS, also creates a file enumerating this communities

    python3 suspect-as-aggregator.py --suffix rv2
    

    • as-path-community-tracker.py takes a path (e.g., UPDATES dir from bgp collector) and a suffix and creates a file containing the MRT entries (readable) that contain the communities appearing for more than one AS

    python3 as-path-community-tracker.py --path path/to/rv2/month/UPDATES/ --suffix rv2
    

    • mrt_line_searcher.py takes the input of the previous .py and counts how many appear for non-sibling ASes, prints them

    python3 mrt_line_searcher.py --suffix rv2
    

• traceroute emulation

  • traceroute_emulation.py starts an interactive emulation
    • command for traceroute:

    h1 traceroute -N 1 -q 1 h2
    

• traceroute address generation

  • address-gatherer.py takes one argument, the company name, and generates a txt in the data/ directory containing the related prefixes
  • address_generator.py can be used to generate random addresses from a prefix
  • address-generator-meta.py generates 100 addresses for each prefix found in the files in the data/ directory

• tshark: pcap exploration

  • search for SR specific ipv6 header

  tshark -n -r path.pcap -Y ipv6.routing.type==4 > output.txt
