See the file COPYING for more details. Requirements ------------ Since 1.0pre3, we use OpenSSL for all cryptographic functions. So you need to install this library first; grab it from http://www.openssl.org/. We recommend version 0.9.5 or better. If this library is not installed on you system, configure will fail. The manual in doc/tinc.texi contains more detailed information on how to install this library. Features -------- This version of tinc supports multiple virtual networks at once. To use this feature, you may supply a netname via the -n or --net options. The standard locations for the config files will then be /etc/tinc//. Because of this feature, tinc will send packets directly to their destinations, instead of to the uplink. If this behaviour is undesirable (for instance because of firewalls or other restrictions), please use an older version of tinc (I would recommend tinc-0.2.19). In this version, MAC addresses are stripped off before encoding and sending a packet. When the packet reaches its destination, the MAC addresses are rebuilt again. They then have the form FE:FD:aa:bb:cc:dd. aa, bb, cc and dd are taken from the destination and source IP address. See the manual for more detailed information. tincd regenerates its encryption key pairs. It does this on the first activity after the keys have expired. This period is adjustable in the configuration file, and the default time is 3600 seconds (one hour). If you send a USR2 signal to the daemon, it'll regenerate immediately.
