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


       -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

           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:

               log to syslog daemon, parameters <level>[,<logname>[,<facility>]]

               log to file, parameters <level>[,<path>]

               log to standard output, parameters <level>

               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

           Possible values:

               no random function, keys and salt are set to 0..00

               AES in counter mode with 128 Bits, default value

               AES in counter mode with 128 Bits

               AES in counter mode with 192 Bits

               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).


       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 -R -e server >> routingtable


       Most likely there are some bugs in Anytun. If you find a bug, please let the developers
       know at Of course, patches are preferred.
