Summary : A virtual private network daemon
URL : http://www.tinc-vpn.org/
License : GPLv2+
Description : 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 tunnel appears to the IP level network
: code as a normal network device, there is no need to adapt any
: existing software. This tunnelling allows VPN sites to share
: information with each other over the Internet without exposing any
: information to others.
