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
The following targets are supported:
log to syslog daemon, parameters
log to file, parameters
log to standard output, parameters
log to standard error, parameters
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
-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
Resolv to IPv4 addresses only. The default is
to resolv both IPv4 and IPv6 addresses.
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
-m, --mux <mux-id>
the multiplex id to use. default: 0
-w, --window-size <window size>
-k, --kd—prf <kd-prf type>
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.
-e, --role <role>
key derivation pseudo random function
The pseudo random function which is used for calculating the session keys and
no random function, keys and salt are set to
AES in counter mode with 128 Bits, default
AES in counter mode with 128 Bits
AES in counter mode with 192 Bits
AES in counter mode with 256 Bits
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>
-A, --salt <master salt>
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).
master salt to use for key derivation
Master salt in hexadecimal notation, e.g. 01a2b3c4d5e6f708a9b0cadbecfd, with a
mandatory length of 28 characters (14 bytes).
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
Most likely there are some bugs in Anytun
. If you find a bug, please let
