tinc (1.0.27-1) unstable; urgency=medium
This package now provides native systemd service files, allowing multiple
instances of tinc to be managed. Existing networks listed in
/etc/tinc/nets.boot will be converted to service instances once during this
upgrade. Afterwards, you can enable and disable networks using:
systemctl enable tinc@<netname>
systemctl disable tinc@<netname>
If you do not have systemd installed, the SysV init script will continue to
work as usual. For more information, see README.Debian.

tinc for Debian
----------------------
---------------
The manual for tinc is also available as info pages, type `info tinc'
to read it.
The system startup script for tinc, /etc/init.d/tinc, uses the file
/etc/tinc/nets.boot to find out which networks have to be started.
There are several ways in which tinc may be automatically started at boot:
Alternatively, you can create a stanza in /etc/network/interfaces, and add a
line with "tinc-net <netname>". This will cause a tincd to be started which
uses the configuration from /etc/tinc/<netname>. You can use an inet static
(with address and netmask options) or inet dhcp stanza, in which case the ifup
will configure the VPN interface and you do not need to have a tinc-up script.
Systemd
-------
Since 1.0.27-1, the tinc package comes with native systemd service files.
To enable and start a net, call:
systemctl enable tinc@<netname>
systemctl start tinc@<netname>
This will cause a tincd to be started which uses the configuration from
/etc/tinc/<netname>, and also makes sure that it will be started next time your
system boots.
Apart from controlling individual instances, you can also start/stop/reload all
enabled instances simultaneously by omitting @<netname>, for example:
systemctl reload tinc
Note that when you have systemd installed on your system, the file
/etc/tinc/nets.boot will not be used anymore to automatically start tinc
daemons. If the variable EXTRA is defined in /etc/default/tinc, it will be
passed on to tinc. The variable LIMITS is however not used.
The service files that come with this package start tinc unconditionally.
However, tinc does support socket activation. If you wish to write a socket
unit for tinc, use the ListenStream option to specify on which port(s) and
address(es) tinc should listen.
SysVinit
--------
The system startup script for tinc, /etc/init.d/tinc, uses the file
/etc/tinc/nets.boot to find out which networks have to be started. Use one
netname per line. Lines starting with a # are ignored.
/etc/network/interfaces
-----------------------
You can create a stanza in /etc/network/interfaces, and add a line with
"tinc-net <netname>". This will cause a tincd to be started which uses the
configuration from /etc/tinc/<netname>. You can use an inet static (with
address and netmask options) or inet dhcp stanza, in which case the ifup will
configure the VPN interface and you do not need to have a tinc-up script.
The following options are also recognized and map directly to the corresponding
command line options for tincd:

This will start a tinc daemon that reads its configuration from
/etc/tinc/myvpn, logs at debug level 1, locks itself in RAM, runs as user

"vpn". Ifup then sets the address and netmask on that interface.

Tinc on Darwin relies on a tunnel driver for its data acquisition from
the kernel. Tinc supports either the driver from
the kernel. OS X version 10.6.8 and later have a built-in tun driver
called "utun". Tinc also supports the driver from
<http://tuntaposx.sourceforge.net/>, which supports both tun and tap
style devices.
By default, tinc expects the tuntaposx driver to be installed. To
use the utun driver, set add 'Device = utunX' to 'tinc.conf', where X is
the desired number for the utun interface. You can also omit the
number, in which case the first free number will be chosen.
