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.


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.[4]

Future goals[edit]

The authors of Tinc have goals of providing a platform that is secure, stable, reliable, scalable, easily configurable, and flexible.[4]

Embedded technologies[edit]

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".[4]
