✨ BLAEU(1) ✨

Ok so bestie, this is a page from the User Commands section of the manual, and it's about Blaeu — a traceroute tool that borrows the whole RIPE Atlas probe squad to do the work. Main character energy, honestly. 🛰️💖

🦋 NAME 🦋

Blaeu — traceroute using RIPE Atlas probes. Like regular traceroute but it's not just your laptop doing the heavy lifting, it's an entire global network of probes. slay 💅

🎀 SYNOPSIS 🎀

blaeu-traceroute target-IP-address-or-name

🌸 DESCRIPTION 🌸

💜 General options are:

  • --verbose, -v — makes the program more talkative. It will yap, and that's a good thing here. 🗣️
  • --help, -h — prints this message. The classic "help me bestie" flag. 🆘
  • --displayprobes, -o — displays the probes numbers. ⚠️ WARNING: big lists. Like, big big. Get ready to scroll, fr fr.
  • --displayprobeasns — displays the (unique) probe ASNumbers. Heads up: currently only for blaeu-resolve. 🧐
  • --cache-probes=<file.json> — caches probe data. Reuse the vibes, save the requests. 💾
  • --country=2LETTERSCODE, -c 2LETTERSCODE — limits the measurements to one country. Default is world-wide, i.e. the entire planet. 🌍
  • --area=AREACODE, -a AREACODE — limits the measurements to one area, such as North-Central. Default is world-wide. 🗺️
  • --asn=ASnumber, -n ASnumber — limits the measurements to one AS. Default is all ASes. 🏢
  • --prefix=IPprefix, -f IPprefix — limits the measurements to one IP prefix. Default is all prefixes. ⚠️ WARNING: it must be an exact prefix in the global routing table — no approximating, no guessing, exact only. 🙅♀️
  • --probes=N, -s N — selects the probes by giving explicit ID (one ID or a comma-separated list). Pick your faves by hand. 🎯
  • --requested=N, -r N — requests N probes. Default is 5. 🙋♀️
  • --percentage=X, -p X — stops the program as soon as X % of the probes reported a result. Default is 90 %. Once enough people answer, we're out. 🚪
  • --measurement-ID=N, -m N — do not start a measurement, just analyze a former one. ✨Recycling✨, we love to see it.
  • --old-measurement MSMID, -g MSMID — uses the probes of measurement MSMID. Same squad, new mission. 🫶
  • --include TAGS, -i TAGS — limits the measurements to probes with these tags (a comma-separated list). 🏷️
  • --exclude TAGS, -e TAGS — excludes from measurements the probes with these tags (a comma-separated list). Not invited, periodt. 🚫
  • --port=N, -t N — destination port for TCP. Default is 80. 🔌
  • --size=N, -z N — number of bytes in the packet. Default is 64 bytes. 📦
  • --ipv4, -4 — uses IPv4. Default is IPv6, except if the parameter or option is an IP address, then it is automatically found. She just knows. 💫
  • --tags TAGS — tag the measurement (no relationship with probes tags) (a comma-separated list). These are your tags, bestie, not the probes'. 🏷️✨
  • --spread, -w — spreads the tests (add a delay before the tests). Giving everyone some personal space. ⏳
  • --private — makes the measurement private. 🤫
  • --resolve-on-probe — resolve names with the probe's DNS resolver. Let the probe handle its own business. 🧚
  • --machine-readable, -b — machine-readable output, to be consumed by tools like grep or cut. Robots deserve nice things too. 🤖

⭐ Also:

  • --format, -k — downloads the results and format them in a traditional traceroute way. Old school, but make it cute. 📜
  • --simpleformat — the same, but without looking up the AS (useful if you have no whois access). Lighter, faster, no whois required. 🪶
  • --protocol=PROTO, -j PROTO — uses this protocol (UDP, TCP or ICMP, default is UDP). Pick your fighter. 🥊
  • --do_lookup, -d — Enables IP lookup feature (default is disabled, may become interactive if the machine has several addresses). ⚠️ Heads up: it can get interactive on you if the machine has several addresses. 👀
  • --do_reverse_lookup, -l — Enables reverse IP lookup feature for hops. Names for every hop, we're being thorough. 🔍
  • --first_hop=N, -y N — TTL/max hop count for the first hop (default 1). 🚩
  • --max_hops=N, -x N — TTL/max hop count for the last hop (default 32). 🏁
