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 k, -kill Ns Op = Ns Ar SIGNAL
55 Attempt to kill a running
57 (optionally with the specified
59 instead of SIGTERM) and exit.
60 Under Windows (not Cygwin) the optional argument is ignored,
61 the service will always be stopped and removed.
62 .It Fl n, -net Ns = Ns Ar NETNAME
65 .It Fl K, -generate-keys Ns Op = Ns Ar BITS
66 Generate public/private RSA keypair and exit.
69 is omitted, the default length will be 1024 bits.
70 When saving keys to existing files, tinc will not delete the old keys,
71 you have to remove them manually.
73 Lock tinc into main memory.
74 This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.
75 .It Fl -logfile Ns Op = Ns Ar FILE
76 Write log entries to a file instead of to the system logging facility.
79 is omitted, the default is
80 .Pa @localstatedir@/log/tinc. Ns Ar NETNAME Ns Pa .log.
81 .It Fl -pidfile Ns = Ns Ar FILE
85 .Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
86 Under Windows this option will be ignored.
87 .It Fl -bypass-security
88 Disables encryption and authentication of the meta protocol.
89 Only useful for debugging.
91 Display short list of options.
93 Output version information and exit.

100 to try to connect to all uplinks immediately.
103 attempts to do this itself,
104 but increases the time it waits between the attempts each time it failed,
107 didn't succeed to connect to an uplink the first time after it started,
108 it defaults to the maximum time of 15 minutes.
110 Partially rereads configuration files.
111 Connections to hosts whose host config file are removed are closed.
112 New outgoing connections specified in
116 Temporarily increases debug level to 5.
117 Send this signal again to revert to the original level.
119 Dumps the connection list to syslog.
121 Dumps virtual network device statistics, all known nodes, edges and subnets to syslog.
123 Purges all information remembered about unreachable nodes.
126 The tinc daemon can send a lot of messages to the syslog.
127 The higher the debug level,
128 the more messages it will log.
129 Each level inherits all messages of the previous level:
130 .Bl -tag -width indent
132 This will log a message indicating
134 has started along with a version number.
135 It will also log any serious error.
137 This will log all connections that are made with other tinc daemons.
139 This will log status and error messages from scripts and other tinc daemons.
141 This will log all requests that are exchanged with other tinc daemons. These include
142 authentication, key exchange and connection list updates.
144 This will log a copy of everything received on the meta socket.
146 This will log all network traffic over the virtual private network.
