Tinc (protocol)

Tinc (protocol) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tinc (protocol) rather than just read about it. In short: Tinc is an open-source, self-routing, mesh networking protocol and software implementation used for compressed and encrypted virtual private networks. It was started in 1998 by Guus Sliepen, Ivo Timmermans, and Wessel Dankers, and released as a GPL-licensed project.

Key takeaways

Tinc (protocol) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tinc (protocol) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tinc (protocol) from memory before moving on to harder problems.

Reference excerpt

Tinc is an open-source, self-routing, mesh networking protocol and software implementation used for compressed and encrypted virtual private networks. It was started in 1998 by Guus Sliepen, Ivo Timmermans, and Wessel Dankers, and released as a GPL-licensed project.

Platforms Tinc is available on Linux, FreeBSD, OpenBSD, NetBSD, DragonFly BSD, Mac OS X, Microsoft Windows, Solaris, iOS (jailbroken only), Android with full support for IPv6.

Future goals The authors of Tinc have goals of providing a platform that is secure, stable, reliable, scalable, easily configurable, and flexible.

Embedded technologies Tinc uses OpenSSL or LibreSSL as the encryption library and gives the options of compressing communications with zlib for "best compression" or LZO for "fast compression".

Projects that use tinc Freifunk has tinc enabled in their routers as of October 2006. OpenWrt has an installable package for tinc. OPNsense, an open source router and firewall distribution, has a plugin for Tinc pfSense has an installable package in the 2.3 release. Tomato variants Shibby and FreshTomato include Tinc support. NYC Mesh uses tinc to connect parts of the mesh over the public internet that would be otherwise out of range.

Worked examples

Example 1 — a first encounter with Tinc (protocol)

Start with the simplest possible case. Write down what Tinc (protocol) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tinc (protocol) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tinc (protocol) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tinc (protocol)

In research: Tinc (protocol) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tinc (protocol) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tinc (protocol) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet Protocol based network software, Internet protocols, Mesh networking, so understanding it makes those chapters shorter.
In everyday life: Look for Tinc (protocol) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
