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.

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.

|
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
|
2000-10-31 16:10:17 +00:00
|
|
|
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.
