Welcome to tinc!
Latest stable version: 1.0.23
Latest prerelease from the 1.1 branch: 1.1pre10
Version 1.1pre10 released.
- Added a benchmark tool (sptps_speed) for the new protocol.
- Fixed a crash when using Name = $HOST while $HOST is not set.
- Use AES-256-GCM for the new protocol.
- Updated support for Solaris.
- Allow running tincd without a private ECDSA key present when ExperimentalProtocol is not explicitly set.
- Enable various compiler hardening flags by default.
- Added support for a “conf.d” configuration directory.
- Fix tinc-gui on Windows, also allowing it to connect to a 32-bits tincd when tinc-gui is run in a 64-bits Python environment.
- Added a “ListenAddress” option, which like BindToAddress adds more listening address/ports, but doesn’t bind to them for outgoing sockets.
- Make invitations work better when the “invite” and “join” commands are not run interactively.
- When creating meta-connections to a node for which no Address statement is specified, try to use addresses learned from other nodes.
Thanks to Dennis Joachimsthaler and Florent Clairambault for their contribution to this version of tinc.
What is tinc?
tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet. tinc is Free Software and licensed under the GNU General Public License version 2 or later. Because the VPN appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This allows VPN sites to share information with each other over the Internet without exposing any information to others. In addition, tinc has the following features:
- Encryption, authentication and compression
- All traffic is optionally compressed using zlib or LZO, and OpenSSL is used to encrypt the traffic and protect it from alteration with message authentication codes and sequence numbers.
- Automatic full mesh routing
- Regardless of how you set up the tinc daemons to connect to each other, VPN traffic is always (if possible) sent directly to the destination, without going through intermediate hops.
- Easily expand your VPN
- When you want to add nodes to your VPN, all you have to do is add an extra configuration file, there is no need to start new daemons or create and configure new devices or network interfaces.
- Ability to bridge ethernet segments
- You can link multiple ethernet segments together to work like a single segment, allowing you to run applications and games that normally only work on a LAN over the Internet.
- Runs on many operating systems and supports IPv6
- Currently Linux, FreeBSD, OpenBSD, NetBSD, MacOS/X, Solaris, Windows 2000, XP, Vista and Windows 7 and 8 platforms are supported. See our section about supported platforms for more information about the state of the ports. tinc has also full support for IPv6, providing both the possibility of tunneling IPv6 traffic over its tunnels and of creating tunnels over existing IPv6 networks.
