24 This is the daemon of tinc, a secure virtual private network (VPN) project.
27 will read it's configuration file to determine what virtual subnets it has to serve
28 and to what other tinc daemons it should connect.
29 It will connect to the ethertap or tun/tap device
30 and set up a socket for incoming connections.
31 Optionally a script will be executed to further configure the virtual device.
33 it will detach from the controlling terminal and continue in the background,
34 accepting and setting up connections to other tinc daemons
35 that are part of the virtual private network.
36 Under Windows (not Cygwin) tinc will install itself as a service,
37 which will be restarted automatically after reboots.

41 Read configuration files from

46 Don't fork and detach.
47 This will also disable the automatic restart mechanism for fatal errors.
48 If not mentioned otherwise, this will show log messages on the standard error output.

50 Increase debug level or set it to
53 .It Fl n, -net Ns = Ns Ar NETNAME
57 Lock tinc into main memory.
58 This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.

72 .It Fl -bypass-security
73 Disables encryption and authentication of the meta protocol.
74 Only useful for debugging.
76 With this option tinc chroots into the directory where network
77 config is located (@sysconfdir@/tinc/NETNAME if -n option is used,
78 or to the directory specified with -c option) after initialization.

99 The higher the debug level,
100 the more messages it will log.
101 Each level inherits all messages of the previous level:

104 This will log a message indicating
106 has started along with a version number.
107 It will also log any serious error.
109 This will log all connections that are made with other tinc daemons.
111 This will log status and error messages from scripts and other tinc daemons.
113 This will log all requests that are exchanged with other tinc daemons. These include
114 authentication, key exchange and connection list updates.
116 This will log a copy of everything received on the meta socket.
118 This will log all network traffic over the virtual private network.
