1.2 tinc

I really don’t quite remember what got us started, but it must have been Guus’ idea. He wrote a simple implementation (about 50 lines of C) that used the ethertap device that Linux knows of since somewhere about kernel 2.1.60. It didn’t work immediately and he improved it a bit. At this stage, the project was still simply called "vpnd".

Since then, a lot has changed—to say the least.

Tinc now supports encryption, it consists of a single daemon (tincd) for both the receiving and sending end, it has become largely runtime-configurable—in short, it has become a full-fledged professional package.

Tinc also allows more than two sites to connect to each other and form a single VPN. Traditionally VPNs are created by making tunnels, which only have two endpoints. Larger VPNs with more sites are created by adding more tunnels. Tinc takes another approach: only endpoints are specified, the software itself will take care of creating the tunnels. This allows for easier configuration and improved scalability.

A lot can—and will be—changed. We have a number of things that we would like to see in the future releases of tinc. Not everything will be available in the near future. Our first objective is to make tinc work perfectly as it stands, and then add more advanced features.

Meanwhile, we’re always open-minded towards new ideas. And we’re available too.
