NAME
----
anytun-config - anycast tunneling configuration utility

SYNOPSIS
--------

*anytun-config*
[ *-h|--help* ]
[ *-r|--remote-host* <hostname|ip> ]
[ *-o|--remote-port* <port> ]
[ *-w|--window-size* <window size> ]
[ *-m|--mux* <mux-id> ]
[ *-K|--key* <master key> ]
[ *-A|--salt* <master salt> ]
[ *-T|--route* <net>/<prefix length> ]

DESCRIPTION
-----------

*anytun-config* writes routing/connection table entries, that can be read by *anytun-controld*.

OPTIONS
-------

-r|--remote-host <hostname|ip>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

remote host

This option can be used to specify the remote tunnel
endpoint. In case of anycast tunnel endpoints, the
anycast IP address has to be used. If you do not specify
an address, it is automatically determined after receiving
the first data packet.

-o|--remote-port <port>
~~~~~~~~~~~~~~~~~~~~~~~
remote port

The UDP port used for payload data by the remote host
(specified with -p on the remote host). If you do not specify
a port, it is automatically determined after receiving
the first data packet.

-w|--window-size <window size>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

seqence window size

Sometimes, packets arrive out of order on the receiver
side. This option defines the size of a list of received
packets' sequence numbers. If, according to this list,
a received packet has been previously received or has
been transmitted in the past, and is therefore not in
the list anymore, this is interpreted as a replay attack
and the packet is dropped. A value of 0 deactivates this
list and, as a consequence, the replay protection employed
by filtering packets according to their secuence number.
By default the sequence window is disabled and therefore a
window size of 0 is used.

-m|--mux <mux-id>
~~~~~~~~~~~~~~~~~

the multiplex id to use. default: 0

-K|--key <master key>
~~~~~~~~~~~~~~~~~~~~~

master key to use for encryption

Master key in hexadecimal notation, eg
01a2b3c4d5e6f708a9b0cadbecfd0fa1, with a mandatory length
of 32 characters (16 bytes).

-A|--salt <master salt>
~~~~~~~~~~~~~~~~~~~~~~~

master salt to use for encryption

Master salt in hexadecimal notation, eg
01a2b3c4d5e6f708a9b0cadbecfd, with a mandatory length
of 28 characters (14 bytes).

-T|--route <net>/<prefix length>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

add a route to connection. This can be invoked several times.


EXAMPLES
--------

Add a client with Connection ID (Mux) 12 and add 2 Routes to this client
 
--------------------------------------------------------------------------------------
# anytun -w 0 -m 12 -K 0123456789ABCDEFFEDCBA9876543210 -A 0123456789ABCDDCBA9876543210 \
         -R 192.0.2.0/24 -R 192.168.1.1/32 >> routingtable
