25 This is the daemon of tinc, a secure virtual private network (VPN) project.
28 will read it's configuration file to determine what virtual subnets it has to serve
29 and to what other tinc daemons it should connect.
30 It will connect to the ethertap or tun/tap device
31 and set up a socket for incoming connections.
32 Optionally a script will be executed to further configure the virtual device.
34 it will detach from the controlling terminal and continue in the background,
35 accepting and setting up connections to other tinc daemons
36 that are part of the virtual private network.
37 Under Windows (not Cygwin) tinc will install itself as a service,
38 which will be restarted automatically after reboots.
40 .Bl -tag -width indent
41 .It Fl c, -config Ns = Ns Ar DIR
42 Read configuration files from
45 .Pa @sysconfdir@/tinc/ .
47 Don't fork and detach.
48 This will also disable the automatic restart mechanism for fatal errors.
49 If not mentioned otherwise, this will show log messages on the standard error output.
50 .It Fl d, -debug Ns Op = Ns Ar LEVEL
51 Increase debug level or set it to
54 .It Fl n, -net Ns = Ns Ar NETNAME
57 This will let tinc read all configuration files from
58 .Pa @sysconfdir@/tinc/ Ar NETNAME .
63 is the same as not specifying any
65 .It Fl o, -option Ns = Ns Ar [HOST.]KEY=VALUE
68 this will set server configuration variable
74 this will set the host configuration variable
80 This option can be used more than once to specify multiple configuration variables.
82 Lock tinc into main memory.
83 This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.
84 This option is not supported on all platforms.
85 .It Fl -logfile Ns Op = Ns Ar FILE
86 Write log entries to a file instead of to the system logging facility.
89 is omitted, the default is
90 .Pa @localstatedir@/log/tinc. Ns Ar NETNAME Ns Pa .log.
91 .It Fl -pidfile Ns = Ns Ar FILENAME
99 is omitted, the default is
100 .Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
101 .It Fl -bypass-security
102 Disables encryption and authentication of the meta protocol.
103 Only useful for debugging.
105 With this option tinc chroots into the directory where network
106 config is located (@sysconfdir@/tinc/NETNAME if -n option is used,
107 or to the directory specified with -c option) after initialization.
108 This option is not supported on all platforms.
109 .It Fl U, -user Ns = Ns Ar USER
110 setuid to the specified
112 after initialization.
113 This option is not supported on all platforms.
115 Display short list of options.
117 Output version information and exit.

124 to try to connect to all uplinks immediately.
127 attempts to do this itself,
128 but increases the time it waits between the attempts each time it failed,
131 didn't succeed to connect to an uplink the first time after it started,
132 it defaults to the maximum time of 15 minutes.
134 Partially rereads configuration files.
135 Connections to hosts whose host config file are removed are closed.
136 New outgoing connections specified in
141 option is used, this will also close and reopen the log file,
142 useful when log rotation is used.
145 The tinc daemon can send a lot of messages to the syslog.
146 The higher the debug level,
147 the more messages it will log.
148 Each level inherits all messages of the previous level:
149 .Bl -tag -width indent
151 This will log a message indicating
153 has started along with a version number.
154 It will also log any serious error.
156 This will log all connections that are made with other tinc daemons.
158 This will log status and error messages from scripts and other tinc daemons.
160 This will log all requests that are exchanged with other tinc daemons. These include
161 authentication, key exchange and connection list updates.
163 This will log a copy of everything received on the meta socket.
165 This will log all network traffic over the virtual private network.

169 .It Pa @sysconfdir@/tinc/
170 Directory containing the configuration files tinc uses.

174 The PID of the currently running
176 is stored in this file.
181 option may not work correctly.
183 .Sy The cryptography in tinc is not well tested yet. Use it at your own risk!
