1 tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and
2 encryption to create a secure private network between hosts on the Internet.
4 Because the VPN appears to the IP level network code as a normal network
5 device, there is no need to adapt any existing software. This allows VPN
6 sites to share information with each other over the Internet without exposing
7 any information to others. In addition, tinc has the following features:
9 o Encryption, authentication and compression
10 All traffic is optionally compressed using zlib or LZO, and OpenSSL is
11 used to encrypt the traffic and protect it from alteration with message
12 authentication codes and sequence numbers.
13 o Automatic full mesh routing
14 Regardless of how you set up the tinc daemons to connect to each
15 other, VPN traffic is always (if possible) sent directly to the
16 destination, without going through intermediate hops.
17 o Easily expand your VPN
18 When you want to add nodes to your VPN, all you have to do is add an extra
19 configuration file, there is no need to start new daemons or create and
20 configure new devices or network interfaces.
21 o Ability to bridge ethernet segments
22 You can link multiple ethernet segments together to work like a single
23 segment, allowing you to run applications and games that normally only work
24 on a LAN over the Internet.
