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
------------------
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
uses strong authentication with RSA keys.
On the 29th of December 2001, Jerome Etienne posted a security analysis of tinc
1.0pre4. Due to a lack of sequence numbers and a message authentication code
for each packet, an attacker could possibly disrupt certain network services or
launch a denial of service attack by replaying intercepted packets. The current
version adds sequence numbers and message authentication codes to prevent such
attacks.
On September the 15th of 2003, Peter Gutmann contacted us and showed us a
writeup describing various security issues in several VPN daemons. He showed
that tinc lacks perfect forward security, the connection authentication could
be done more properly, that the sequence number we use as an IV is not the best
practice and that the default length of the HMAC for packets is too short in
his opinion. We do not know of a way to exploit these weaknesses, but these
issues are being addressed in the tinc 1.1 branch.
The Sweet32 attack affects versions of tinc prior to 1.0.30.
On September 6th, 2018, Michael Yonly contacted us and provided
proof-of-concept code that allowed a remote attacker to create an
authenticated, one-way connection with a node, and also that there was a
possibility for a man-in-the-middle to force UDP packets from a node to be sent
in plaintext. The first issue was trivial to exploit on tinc versions prior to
1.0.30, but the changes in 1.0.30 to mitigate the Sweet32 attack made this
weakness much harder to exploit. These issues have been fixed in tinc 1.0.35.
The new protocol in the tinc 1.1 branch is not susceptible to these issues.
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 strongly encouraged to do so.
This version uses an experimental and unfinished cryptographic protocol. Use
it at your own risk.
Compatibility
-------------
Version 1.0.35 is compatible with 1.0pre8, 1.0 and later, but not with older
versions of tinc. Note that since version 1.0.30, tinc requires all nodes in
the VPN to be compiled with a version of LibreSSL or OpenSSL that supports the
AES256 and SHA256 algorithms.
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
------------
The OpenSSL library is used for all cryptographic functions. You can find it at
https://www.openssl.org/. You will need version 1.0.1 or later with support for
AES256 and SHA256 enabled. If this library is not installed on your system, the
configure script will fail. The manual in doc/tinc.texi contains more detailed
information on how to install this library. Alternatively, you may also use the
LibreSSL library.
Either OpenSSL (http://www.openssl.org/) or libgcrypt
(http://www.gnupg.org/download/#libgcrypt).
The zlib library is used for optional compression. You can
find it at https://zlib.net/. Because of a possible exploit in
earlier versions we recommend that you download version 1.1.4 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 https://www.oberhumer.com/opensource/lzo/.
The lzo library is also used for optional compression. You can find it at
http://www.oberhumer.com/opensource/lzo/.
In order to compile tinc, you will need a C99 compliant compiler.
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.

.Sh SYNOPSIS
.Nm
.Op Fl n
.Op Fl -net Ns = Ns Ar NETNAME
.Op Fl -pidfile Ns = Ns Ar FILENAME
.Op Fl -help
.Sh DESCRIPTION
This is a Python/wxWidgets based graphical user interface for tinc, a secure virtual private network (VPN) project.
.Nm
communicates with
.Xr tincd 8
to alter and inspect the running VPN's state.
It can show the current settings, the list of connections, nodes, subnets, and edges.
For now, the debug level can be changed from the GUI, and by right-clicking on a node in the list of connections,
a pop-up menu will appear that allows one to disconnect that node.
.Sh OPTIONS
.Bl -tag -width indent
.It Fl n, -net Ns = Ns Ar NETNAME
Communicate with tincd(8) connected with
.Ar NETNAME .
.It Fl -pidfile Ns = Ns Ar FILENAME
Use the cookie from
.Ar FILENAME
to authenticate with a running tinc daemon.
If unspecified, the default is
.Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
.It Fl -help
Display short list of options.
.El
.Sh BUGS
The GUI is not finished yet, the final version will have much more functionality.
If you find any bugs, report them to tinc@tinc-vpn.org.
.Sh SEE ALSO
.Xr tincd 8 ,
.Pa http://www.tinc-vpn.org/ .
.Pp
The full documentation for tinc is maintained as a Texinfo manual.
If the info and tinc programs are properly installed at your site,
the command
.Ic info tinc
should give you access to the complete manual.

The server configuration is complemented with host specific configuration (see the next section).
Although all configuration options for the local host listed in this document can also be put in
.Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /tinc.conf ,
it is recommended to put host specific configuration options in the host configuration file,
as this makes it easy to exchange with other nodes.
.Pp
Here are all valid variables, listed in alphabetical order.
The default value is given between parentheses.
.Bl -tag -width indent
.It Va AddressFamily Li = ipv4 | ipv6 | any Pq any
This option affects the address family of listening and outgoing sockets.
If
.Qq any
is selected, then depending on the operating system both IPv4 and IPv6 or just
IPv6 listening sockets will be created.
.It Va BindToAddress Li = Ar address Oo Ar port Oc Bq experimental
.It Va BindToAddress Li = Ar address Bq experimental
If your computer has more than one IPv4 or IPv6 address,
.Nm tinc
will by default listen on all of them for incoming connections.
Multiple
.Va BindToAddress
variables may be specified,
in which case listening sockets for each specified address are made.
.Pp
If no
.Ar port
is specified, the socket will be bound to the port specified by the
.Va Port
option, or to port 655 if neither is given.
To only bind to a specific port but not to a specific address, use
.Li *
for the
.Ar address .
It is possible to bind only to a single address with this variable.
.Pp
This option may not work on all platforms.
.It Va BindToInterface Li = Ar interface Bq experimental
If your computer has more than one network interface,
.Nm tinc
will by default listen on all of them for incoming connections.
It is possible to bind only to a single interface with this variable.
.Pp
This option may not work on all platforms.
Also, on some platforms it will not actually bind to an interface,
but rather to the address that the interface has at the moment a socket is created.
.It Va Broadcast Li = no | mst | direct Po mst Pc Bq experimental
This option selects the way broadcast packets are sent to other daemons.
NOTE: all nodes in a VPN must use the same
.Va Broadcast
mode, otherwise routing loops can form.
.Bl -tag -width indent
.It no
Broadcast packets are never sent to other nodes.
.It mst
Broadcast packets are sent and forwarded via the VPN's Minimum Spanning Tree.
This ensures broadcast packets reach all nodes.
.It direct
Broadcast packets are sent directly to all nodes that can be reached directly.
Broadcast packets received from other nodes are never forwarded.
If the IndirectData option is also set, broadcast packets will only be sent to nodes which we have a meta connection to.

Tinc will normally automatically select the right type, and this option should not be used.
However, in case tinc does not seem to correctly interpret packets received from the virtual network device,

.Bl -tag -width indent
.It dummy
Use a dummy interface.
No packets are ever read or written to a virtual network device.
Useful for testing, or when setting up a node that only forwards packets for other nodes.
.It raw_socket
Open a raw socket, and bind it to a pre-existing
.Va Interface
(eth0 by default).
All packets are read from this interface.
Packets received for the local node are written to the raw socket.
However, at least on Linux, the operating system does not process IP packets destined for the local host.
.It multicast
Open a multicast UDP socket and bind it to the address and port (separated by spaces) and optionally a TTL value specified using
.Va Device .
Packets are read from and written to this multicast socket.
This can be used to connect to UML, QEMU or KVM instances listening on the same multicast address.
Do NOT connect multiple
.Nm tinc
daemons to the same multicast address, this will very likely cause routing loops.
Also note that this can cause decrypted VPN packets to be sent out on a real network if misconfigured.

.It tun
Set type to tun.
Depending on the platform, this can either be with or without an address family header (see below).
.It tunnohead Pq BSD
.It tunnohead
Set type to tun without an address family header.
Tinc will expect packets read from the virtual network device to start with an IP header.
On some platforms IPv6 packets cannot be read from or written to the device in this mode.
.It tunifhead Pq BSD
.It tunifhead
Set type to tun with an address family header.
Tinc will expect packets read from the virtual network device
to start with a four byte header containing the address family,
followed by an IP header.
This mode should support both IPv4 and IPv6 packets.
.It utun Pq OS X
Set type to utun.
This is only supported on OS X version 10.6.8 and higher, but doesn't require the tuntaposx module.
This mode should support both IPv4 and IPv6 packets.

.Sh TOP
The top command connects to a running tinc daemon and repeatedly queries its per-node traffic counters.
It displays a list of all the known nodes in the left-most column,
and the amount of bytes and packets read from and sent to each node in the other columns.
By default, the information is updated every second.
The behaviour of the top command can be changed using the following keys:
.Bl -tag
.It Ic s
Change the interval between updates.
After pressing the
.Ic s
key, enter the desired interval in seconds, followed by enter.
Fractional seconds are honored.
Intervals lower than 0.1 seconds are not allowed.
.It Ic c
Toggle between displaying current traffic rates (in packets and bytes per second)
and cummulative traffic (total packets and bytes since the tinc daemon started).
.It Ic n
Sort the list of nodes by name.
.It Ic i
Sort the list of nodes by incoming amount of bytes.
.It Ic I
Sort the list of nodes by incoming amount of packets.
.It Ic o
Sort the list of nodes by outgoing amount of bytes.
.It Ic O
Sort the list of nodes by outgoing amount of packets.
.It Ic t
Sort the list of nodes by sum of incoming and outgoing amount of bytes.
.It Ic T
Sort the list of nodes by sum of incoming and outgoing amount of packets.
.It Ic b
Show amount of traffic in bytes.
.It Ic k
Show amount of traffic in kilobytes.
.It Ic M
Show amount of traffic in megabytes.
.It Ic G
Show amount of traffic in gigabytes.
.It Ic q
Quit.

When saving keys to existing files, tinc will not delete the old keys,
you have to remove them manually.
.It Fl o, -option Ns = Ns Ar [HOST.]KEY=VALUE
Without specifying a

of the host named
.Ar HOST
to
.Ar VALUE .
This option can be used more than once to specify multiple configuration variables.
.It Fl L, -mlock

These files are used by a program called aclocal (part of the GNU automake
package). aclocal uses these files to create aclocal.m4 which is in turn
used by autoconf to create the configure script at the the top level in
this distribution.
The Makefile.am file in this directory is automatically generated
from the template file, Makefile.am.in. The generation will fail
if you don't have all the right tools.

#
# SYNOPSIS
#
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
#
# DESCRIPTION
#
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
# added in between.
#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
# FLAG.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

#
# SYNOPSIS
#
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_CXXFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
# AX_FCFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
#
# DESCRIPTION
#
# Try to find a compiler option that enables most reasonable warnings.
#
# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
#
# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
# Intel compilers. For a given compiler, the Fortran flags are much more
# experimental than their C equivalents.
#
# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
# - $2 add-value-if-not-found : nothing
# - $3 action-if-found : add value to shellvariable
# - $4 action-if-not-found : nothing
#
# NOTE: These macros depend on AX_APPEND_FLAG.

# SYNOPSIS
#
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
#
# DESCRIPTION
#
# Check whether the given FLAG works with the current language's compiler
# or gives an error. (Warnings, however, are ignored)
#
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
# success/failure.
#
# If EXTRA-FLAGS is defined, it is added to the current language's default
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
# force the compiler to issue an error when a bad flag is given.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# SYNOPSIS
#
# AX_REQUIRE_DEFINED(MACRO)
#
# DESCRIPTION
#
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
# been defined and thus are available for use. This avoids random issues
# where a macro isn't expanded. Instead the configure script emits a
# non-fatal:
#
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
#
# It's like AC_REQUIRE except it doesn't expand the required macro.
#
# Here's an example:

Original AVL tree library by Michael H. Buselli <cosine@cosine.org>.
Modified 2000-11-28 by Wessel Dankers <wsl@tinc-vpn.org> to use counts
instead of depths, to add the ->next and ->prev and to generally obfuscate
the code. Mail me if you found a bug.
Cleaned up and incorporated some of the ideas from the red-black tree
library for inclusion into tinc (https://www.tinc-vpn.org/) by
Guus Sliepen <guus@tinc-vpn.org>.

Original AVL tree library by Michael H. Buselli <cosine@cosine.org>.
Modified 2000-11-28 by Wessel Dankers <wsl@tinc-vpn.org> to use counts
instead of depths, to add the ->next and ->prev and to generally obfuscate
the code. Mail me if you found a bug.
Cleaned up and incorporated some of the ideas from the red-black tree
library for inclusion into tinc (https://www.tinc-vpn.org/) by
Guus Sliepen <guus@tinc-vpn.org>.
