54 \fBanytun\-config\fR writes routing/connection table entries, that can be read by \fBanytun\-controld\fR\&.
57 \fB\-L, \-\-log \fR\fB\fI<target>:<level>[,<param1>[,<param2>[\&.\&.]]]\fR\fR
59 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\&.
61 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
62 \fIsyslog:3,anytun\-config,daemon\fR
65 The following targets are supported:
69 log to syslog daemon, parameters <level>[,<logname>[,<facility>]]
74 log to file, parameters <level>[,<path>]
79 log to standard output, parameters <level>
84 log to standard error, parameters <level>
92 to run in debug mode\&. It implicits
94 (don\(cqt daemonize) and adds a log target with the configuration
96 (logging with maximum level)\&. In future releases there might be additional output when this option is supplied\&.
99 \fB\-r, \-\-remote\-host \fR\fB\fI<hostname|ip>\fR\fR
101 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\&.
104 \fB\-o, \-\-remote\-port \fR\fB\fI<port>\fR\fR
106 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\&.
109 \fB\-4, \-\-ipv4\-only\fR
111 Resolv to IPv4 addresses only\&. The default is to resolv both IPv4 and IPv6 addresses\&.
114 \fB\-6, \-\-ipv6\-only\fR
116 Resolv to IPv6 addresses only\&. The default is to resolv both IPv4 and IPv6 addresses\&.
119 \fB\-R, \-\-route \fR\fB\fI<net>/<prefix length>\fR\fR
121 add a route to connection\&. This can be invoked several times\&.
124 \fB\-m, \-\-mux \fR\fB\fI<mux\-id>\fR\fR
126 the multiplex id to use\&. default: 0
129 \fB\-w, \-\-window\-size \fR\fB\fI<window size>\fR\fR
133 Sometimes, packets arrive out of order on the receiver side\&. This option defines the size of a list of received packets\*(Aq 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\&.
136 \fB\-k, \-\-kd\(emprf \fR\fB\fI<kd\-prf type>\fR\fR
138 key derivation pseudo random function
140 The pseudo random function which is used for calculating the session keys and session salt\&.
146 no random function, keys and salt are set to 0\&.\&.00
151 AES in counter mode with 128 Bits, default value
156 AES in counter mode with 128 Bits
161 AES in counter mode with 192 Bits
166 AES in counter mode with 256 Bits
170 \fB\-e, \-\-role \fR\fB\fI<role>\fR\fR
172 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
175 \fBright\fR\&. You may also use
186 \fBright\fR\&. By default
191 \fB\-E, \-\-passphrase \fR\fB\fI<pass phrase>\fR\fR
193 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
199 \fB\-K, \-\-key \fR\fB\fI<master key>\fR\fR
201 master key to use for key derivation
203 Master key in hexadecimal notation, e\&.g\&. 01a2b3c4d5e6f708a9b0cadbecfd0fa1, with a mandatory length of 32, 48 or 64 characters (128, 192 or 256 bits)\&.
206 \fB\-A, \-\-salt \fR\fB\fI<master salt>\fR\fR
208 master salt to use for key derivation
210 Master salt in hexadecimal notation, e\&.g\&. 01a2b3c4d5e6f708a9b0cadbecfd, with a mandatory length of 28 characters (14 bytes)\&.

228 Most likely there are some bugs in \fBAnytun\fR\&. If you find a bug, please let the developers know at satp@anytun\&.org\&. Of course, patches are preferred\&.
