Tinc is a peer-to-peer VPN daemon that supports VPNs with an arbitrary number of nodes. Instead of configuring tunnels, you give tinc the location and public key of a few nodes in the VPN. After making the initial connections to those nodes, tinc will learn about all other nodes on the VPN, and will make connections automatically. When direct connections are not possible, data will be forwarded by intermediate nodes.

Tinc can operate in several routing modes. In the default mode, "router", every node is associated with one or more IPv4 and/or IPv6 Subnets. The other two modes, "switch" and "hub", let the tinc daemons work together to form a virtual Ethernet network switch or hub.

Please note that this is NOT a stable release. Until version 1.1.0 is released, please use one of the 1.0.x versions if you need a stable version of tinc.

Although tinc 1.1 will be protocol compatible with tinc 1.0.x, the functionality of the tinc program may still change, and the control socket protocol is not fixed yet.

See QUICKSTART.md for a quick guide to get tinc up and running. Read the manual for more detailed information.

Many operating system distributions have packaged tinc. Check your package manager first.

You can download pre-built binary packages for multiple Linux distributions and Windows here:

• development version
• latest release

Note that these packages have not been heavily tested and are not officially supported by the project. Use them at your own risk. You are advised to use tinc shipped by your distribution, or build from source.

See the file INSTALL.md for instructions of how to build and install tinc from source.
