This is a pre-release
|
|
---------------------
|
|
|
|
Please note that this is NOT a stable release. Until version 1.1.0 is released,
|
|
please use one of the 1.0.x versions if you need a stable version of tinc.
|
|
|
|
Although tinc 1.1 will be protocol compatible with tinc 1.0.x, the
|
|
functionality of the tincctl program may still change, and the control socket
|
|
protocol is not fixed yet.
|
|
|
|
|
|
Security statement
|
|
------------------
|
|
|
|
This version uses an experimental and unfinished cryptographic protocol. Use
|
|
it at your own risk.
|
|
|
|
|
|
Compatibility
|
|
-------------
|
|
|
|
Version 1.1pre2 is compatible with 1.0pre8, 1.0 and later, but not with older
|
|
versions of tinc.
|
|
|
|
When the ExperimentalProtocol option is used, tinc is still compatible with
|
|
1.0.X and 1.1pre2 itself, but not with any other 1.1preX version.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
|
|
OpenSSL (http://www.openssl.org/) version 1.0.0 or later.
|
|
|
|
The zlib library is used for optional compression. You can find it at
|
|
http://www.gzip.org/zlib/.
|
|
|
|
The lzo library is also used for optional compression. You can find it at
|
|
http://www.oberhumer.com/opensource/lzo/.
|
|
|
|
Since 1.1, the libevent library is used for the main event loop. You can find
|
|
it at http://monkey.org/~provos/libevent/.
|
|
|
|
In order to compile tinc, you will need a GNU C compiler environment. Please
|
|
ensure you have the latest stable versions of all the required libraries.

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>/.
|
|
|
|
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.
|
|
|
|
Since pre5, tinc can operate in several routing modes. The default mode,
|
|
"router", works exactly like the older version, and uses Subnet lines to
|
|
determine the destination of packets. The other two modes, "switch" and "hub",
|
|
allow the tinc daemons to work together like a single network switch or hub.
|
|
This is useful for bridging networks. The latter modes only work properly on
|
|
Linux, FreeBSD and Windows.
|
|
|
|
The algorithms used for encryption and generating message authentication codes
|
|
can now be changed in the configuration files. All cipher and digest algorithms
|
|
supported by OpenSSL can be used. Useful ciphers are "blowfish" (default),
|
|
"bf-ofb", "des", "des3", etcetera. Useful digests are "sha1" (default), "md5",
|
|
etcetera.
|
|
|
|
Support for routing IPv6 packets has been added. Just add Subnet lines with
|
|
IPv6 addresses (without using :: abbreviations) and use ifconfig or ip (from
|
|
the iproute package) to give the virtual network interface corresponding IPv6
|
|
addresses. tinc does not provide autoconfiguration for IPv6 hosts, if you need
|
|
it use radvd or zebra.
|
|
|
|
It is also possible to make tunnels to other tinc daemons over IPv6 networks,
|
|
if the operating system supports IPv6. tinc will automatically use both IPv6
|
|
and IPv4 when available, but this can be changed by adding the option
|
|
"AddressFamily = ipv4" or "AddressFamily = ipv6" to the tinc.conf file.
|
|
|
|
Normally, when started tinc will detach and run in the background. In a native
|
|
Windows environment this means tinc will intall itself as a service, which will
|
|
restart after reboots. To prevent tinc from detaching or running as a service,
|
|
use the -D option.
