💅 TEREDO-MIRE — the stateless Teredo IPv6 responder, bestie edition 🦋

okay so. this is teredo-mire, a page from the User Commands corner of the manual, and it's giving "tiny chaotic test tool that somehow keeps the whole Teredo vibe alive". sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

teredo-mire — a stateless Teredo IPv6 responder. no cap, that's literally the whole job description. 👑

✨ SYNOPSIS ✨

teredo-mire

that's it. that's the whole synopsis. no flags required, no args, she just runs. periodt. 💅

✨ DESCRIPTON ✨

(yes the heading is spelled like that in the original, we don't gatekeep typos here 🫶)

Teredo-Mire is a test back-end for the Teredo IPv6 tunneling protocol. lowkey a whole icon.

Here's the tea on what she does:

  • She listens for requests from other Teredo clients, or from IPv6 nodes (coming in through Teredo relays).
  • She answers to them statelessly — no memory of you, no follow-up texts, just vibes. ✨
  • Currently, the only thing she handles is ICMPv6 Echo Requests (aka "pings"). that's her whole range bestie, and honestly? she ate. 🔥

✨ OPTIONS ✨

not many, but they're serving:

  • -h or --help — display some help and exit. cute, short, helpful. 🎀
  • -V or --version — display the program version and exit. flex the number and dip. 💜

✨ DIAGNOSTICS ✨

okay so this part is the actual homework, listen up 📚

To contact a teredo-mire responder, a valid Teredo IPv6 address must be determined for it. you can't just slide into her DMs without the right address, bestie.

When you're putting that address together:

  • The server IPv4 address part and the mapped client IPv4 address part should both represent the IPv4 address of the host running teredo-mire.
  • The mapped UDP port number must be 3545. not 3544, not 3546, 3545. lock it in. 🔒
  • The Teredo prefix and the Teredo flags are ignored — she literally does not care. 💀

✨ BUGS ✨

real talk, she has some quirks and we're being honest about them:

  • teredo-mire uses UDP ports 3544 and 3545, and she assumes she has a public IPv4 address. if you don't have one... girl, good luck. 😭
  • Neither RFC 2460 nor RFC 4380 are properly implemented. that's just the situation. not ideal, but we said what we said. 🙈
heads up bestie — these are known limitations, not secrets. plan accordingly.

✨ SECURITY ✨

the good news, the slay news: teredo-mire does not require any privilege to run. no sudo, no root, no nothing. she's low maintenance and high value. 🫶✨
