DESCRIPTION
anytun-config writes routing/connection table entries, that can be read by
anytun-controld.
OPTIONS
-L, --log <target>:<level>[,<param1>[,<param2>[..]]]
add log target to logging system. This can be invoked several times in order to log to
different targets at the same time. Every target hast its own log level which is a
number between 0 and 5. Where 0 means disabling log and 5 means debug messages are
enabled.
The file target can be used more the once with different levels. If no target is
provided at the command line a single target with the config
syslog:3,anytun-config,daemon is added.
The following targets are supported:
syslog
log to syslog daemon, parameters <level>[,<logname>[,<facility>]]
file
log to file, parameters <level>[,<path>]
stdout
log to standard output, parameters <level>
stderr
log to standard error, parameters <level>
-U, --debug
This option instructs Anytun to run in debug mode. It implicits -D (don’t daemonize)
and adds a log target with the configuration stdout:5 (logging with maximum level). In
future releases there might be additional output when this option is supplied.
-r, --remote-host <hostname|ip>
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>
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.
-4, --ipv4-only
Resolv to IPv4 addresses only. The default is to resolv both IPv4 and IPv6 addresses.
-6, --ipv6-only
Resolv to IPv6 addresses only. The default is to resolv both IPv4 and IPv6 addresses.
-R, --route <net>/<prefix length>
add a route to connection. This can be invoked several times.
-m, --mux <mux-id>
the multiplex id to use. default: 0
-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.
-k, --kd—prf <kd-prf type>
key derivation pseudo random function
The pseudo random function which is used for calculating the session keys and session
salt.
Possible values:
null
no random function, keys and salt are set to 0..00
aes-ctr
AES in counter mode with 128 Bits, default value
aes-ctr-128
AES in counter mode with 128 Bits
aes-ctr-192
AES in counter mode with 192 Bits
aes-ctr-256
AES in counter mode with 256 Bits
-e, --role <role>
SATP uses different session keys for inbound and outbound traffic. The role parameter
is used to determine which keys to use for outbound or inbound packets. On both sides
of a vpn connection different roles have to be used. Possible values are left and
right. You may also use alice or server as a replacement for left and bob or client as
a replacement for right. By default left is used.
-E, --passphrase <pass phrase>
This passphrase is used to generate the master key and master salt. For the master key
the last n bits of the SHA256 digest of the passphrase (where n is the length of the
master key in bits) is used. The master salt gets generated with the SHA1 digest. You
may force a specific key and or salt by using --key and --salt.
-K, --key <master key>
master key to use for key derivation
Master key in hexadecimal notation, e.g. 01a2b3c4d5e6f708a9b0cadbecfd0fa1, with a
mandatory length of 32, 48 or 64 characters (128, 192 or 256 bits).
-A, --salt <master salt>
master salt to use for key derivation
Master salt in hexadecimal notation, e.g. 01a2b3c4d5e6f708a9b0cadbecfd, with a
mandatory length of 28 characters (14 bytes).
EXAMPLES
Add a client with Connection ID (Mux) 12 and add 2 Routes to this client
# anytun-config -w 0 -m 12 -K 0123456789ABCDEFFEDCBA9876543210 -A 0123456789ABCDDCBA9876543210 \
-R 192.0.2.0/24 -R 192.168.1.1/32 -e server >> routingtable
BUGS
Most likely there are some bugs in Anytun. If you find a bug, please let the developers
know at satp@anytun.org. Of course, patches are preferred.
