This is the README file for tinc version 1.0pre4. Installation instructions may be found in the INSTALL file. tinc is Copyright (C) 1998-2001 by: Ivo Timmermans <itimmermans@bigfoot.com>, Guus Sliepen <guus@sliepen.warande.net>, and others. For a complete list of authors see the AUTHORS file.

See the file COPYING for more details. Security statement ------------------ In august 2000, we discovered the existence of a security hole in all versions of tinc up to and including 1.0pre2. This had to do with the way we exchanged keys. Since then, we have been working on a new authentication scheme to make tinc as secure as possible. The current version uses the OpenSSL library and does authentication in much the same way as the SSH protocol does. Cryptography is a hard thing to get right. We cannot make any guarantees. Time, review and feedback are the only things that can prove the security of any cryptographic product. If you wish to review tinc or give us feedback, you are stronly encouraged to do so. 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/<net>/. 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 order to force the kernel to accept received packets, the destination MAC address will be set to FE:FD:00:00:00:00 upon reception. The MAC address of the ethertap or tun/tap interface must also be set to this 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). This version supports multiple subnets at once. They are also sorted on subnet mask size. This means that it is possible to have overlapping subnets on the VPN, as long as their subnet mask sizes differ.
