32 *anytun-config* writes routing/connection table entries, that can be read by *anytun-controld*.
37 *-L, --log <target>:<level>[,<param1>[,<param2>[..]]]*::
38 add log target to logging system. This can be invoked several times
39 in order to log to different targets at the same time. Every target
40 hast its own log level which is a number between 0 and 5. Where 0 means
41 disabling log and 5 means debug messages are enabled. +
42 The file target can be used more the once with different levels.
43 If no target is provided at the command line a single target with the
44 config *syslog:3,anytun-config,daemon* is added. +
45 The following targets are supported:
47 *syslog*;; log to syslog daemon, parameters <level>[,<logname>[,<facility>]]
48 *file*;; log to file, parameters <level>[,<path>]
49 *stdout*;; log to standard output, parameters <level>
50 *stderr*;; log to standard error, parameters <level>
52 *-r, --remote-host <hostname|ip>*::
53 This option can be used to specify the remote tunnel
54 endpoint. In case of anycast tunnel endpoints, the
55 anycast IP address has to be used. If you do not specify
56 an address, it is automatically determined after receiving
57 the first data packet.
59 *-o, --remote-port <port>*::
60 The UDP port used for payload data by the remote host
61 (specified with -p on the remote host). If you do not specify
62 a port, it is automatically determined after receiving
63 the first data packet.
66 Resolv to IPv4 addresses only. The default is to resolv both
67 IPv4 and IPv6 addresses.
70 Resolv to IPv6 addresses only. The default is to resolv both
71 IPv4 and IPv6 addresses.
73 *-R, --route <net>/<prefix length>*::
74 add a route to connection. This can be invoked several times.
76 *-m, --mux <mux-id>*::
77 the multiplex id to use. default: 0
79 *-w, --window-size <window size>*::
81 Sometimes, packets arrive out of order on the receiver
82 side. This option defines the size of a list of received
83 packets' sequence numbers. If, according to this list,
84 a received packet has been previously received or has
85 been transmitted in the past, and is therefore not in
86 the list anymore, this is interpreted as a replay attack
87 and the packet is dropped. A value of 0 deactivates this
88 list and, as a consequence, the replay protection employed
89 by filtering packets according to their secuence number.
90 By default the sequence window is disabled and therefore a
91 window size of 0 is used.
93 *-k, --kd--prf <kd-prf type>*::
94 key derivation pseudo random function +
95 The pseudo random function which is used for calculating the
96 session keys and session salt. +
99 *null*;; no random function, keys and salt are set to 0..00
100 *aes-ctr*;; AES in counter mode with 128 Bits, default value
101 *aes-ctr-128*;; AES in counter mode with 128 Bits
102 *aes-ctr-192*;; AES in counter mode with 192 Bits
103 *aes-ctr-256*;; AES in counter mode with 256 Bits
105 *-e, --role <role>*::
106 SATP uses different session keys for inbound and outbound traffic. The
107 role parameter is used to determine which keys to use for outbound or
108 inbound packets. On both sides of a vpn connection different roles have
109 to be used. Possible values are *left* and *right*. You may also use
110 *alice* or *server* as a replacement for *left* and *bob* or *client* as
111 a replacement for *right*. By default *left* is used.
113 *-E, --passphrase <pass phrase>*::
114 This passphrase is used to generate the master key and master salt.
115 For the master key the last n bits of the SHA256 digest of the
116 passphrase (where n is the length of the master key in bits) is used.
117 The master salt gets generated with the SHA1 digest.
118 You may force a specific key and or salt by using *--key* and *--salt*.
120 *-K, --key <master key>*::
121 master key to use for key derivation +
122 Master key in hexadecimal notation, e.g.
123 01a2b3c4d5e6f708a9b0cadbecfd0fa1, with a mandatory length
124 of 32, 48 or 64 characters (128, 192 or 256 bits).
126 *-A, --salt <master salt>*::
127 master salt to use for key derivation +
128 Master salt in hexadecimal notation, e.g.
129 01a2b3c4d5e6f708a9b0cadbecfd, with a mandatory length
130 of 28 characters (14 bytes).

145 Most likely there are some bugs in *Anytun*. If you find a bug, please let
146 the developers know at satp@anytun.org. Of course, patches are preferred.
