tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and
encryption to create a secure private network between hosts on the Internet.
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:
o 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.
o 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.
o 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.
o 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.
