18 This is the control program of tinc, a secure virtual private network (VPN)
23 to alter and inspect the running VPN's state.

26 .It Fl n, -net Ns = Ns Ar NETNAME
27 Communicate with tincd(8) connected with
29 .It Fl -pidfile Ns = Ns Ar FILENAME
32 to authenticate with a running tinc daemon.
33 If unspecified, the default is
34 .Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
36 Display short list of options.
38 Output version information and exit.
40 .Sh ENVIRONMENT VARIABLES
41 .Bl -tag -width indent
43 If no netname is specified on the command line with the
45 option, the value of this environment variable is used.
48 .Bl -tag -width indent
50 Create initial configuration files and RSA and ECDSA keypairs with default length.
53 for this node is given, it will be asked for.
55 Print the current value of configuration variable
57 If more than one variable with the same name exists,
58 the value of each of them will be printed on a separate line.
59 .It set Ar variable Ar value
60 Set configuration variable
64 All previously existing configuration variables with the same name are removed.
65 To set a variable for a specific host, use the notation
66 .Ar host Ns Li . Ns Ar variable .
67 .It add Ar variable Ar value
68 As above, but without removing any previously existing configuration variables.
69 .It del Ar variable Op Ar value
70 Remove configuration variables with the same name and
74 is given, all configuration variables with the same name will be removed.
76 Start an editor for the given configuration file.
77 You do not need to specify the full path to the file.
79 Export the host configuration file of the local node to standard output.
81 Export all host configuration files to standard output.
82 .It import Op Fl -force
83 Import host configuration data generated by the
85 export command from standard input.
86 Already existing host configuration files are not overwritten unless the option
89 .It exchange Op Fl -force
90 The same as export followed by import.
91 .It exchange-all Op Fl -force
92 The same as export-all followed by import.
93 .It start Op tincd options
96 optionally with the given extra options.
104 Partially rereads configuration files. Connections to hosts whose host
105 config files are removed are closed. New outgoing connections specified
110 Shows the PID of the currently running
112 .It generate-keys Op bits
113 Generate both RSA and ECDSA keypairs (see below) and exit.
114 .It generate-ecdsa-keys
115 Generate public/private ECDSA keypair and exit.
116 .It generate-rsa-keys Op bits
117 Generate public/private RSA keypair and exit.
120 is omitted, the default length will be 2048 bits.
121 When saving keys to existing files, tinc will not delete the old keys;
122 you have to remove them manually.
123 .It dump [reachable] nodes
124 Dump a list of all known nodes in the VPN.
125 If the keyword reachable is used, only lists reachable nodes.
127 Dump a list of all known connections in the VPN.
129 Dump a list of all known subnets in the VPN.
131 Dump a list of all meta connections with ourself.
132 .It dump graph | digraph
133 Dump a graph of the VPN in
136 Nodes are colored according to their reachability:
137 red nodes are unreachable, orange nodes are indirectly reachable, green nodes are directly reachable.
138 Black nodes are either directly or indirectly reachable, but direct reachability has not been tried yet.
139 .It info Ar node | subnet | address
140 Show information about a particular node, subnet or address.
141 If an address is given, any matching subnet will be shown.
143 Purges all information remembered about unreachable nodes.
148 Capture log messages from a running tinc daemon.
149 An optional debug level can be given that will be applied only for log messages sent to
154 to try to connect to all uplinks immediately.
157 attempts to do this itself,
158 but increases the time it waits between the attempts each time it failed,
161 didn't succeed to connect to an uplink the first time after it started,
162 it defaults to the maximum time of 15 minutes.
163 .It disconnect Ar NODE
164 Closes the meta connection with the given
169 is compiled with libcurses support, this will display live traffic statistics
170 for all the known nodes, similar to the UNIX
173 See below for more information.
175 Dump VPN traffic going through the local tinc node in
177 format to standard output,
178 from where it can be redirected to a file or piped through a program that can parse it directly,
183 Examples of some commands:
184 .Bd -literal -offset indent
185 tinc -n vpn dump graph | circo -Txlib
186 tinc -n vpn pcap | tcpdump -r -
190 Example of configuring tinc using
192 .Bd -literal -offset indent
194 tinc -n vpn add Subnet 192.168.1.0/24
195 tinc -n vpn add bar.Address bar.example.com
196 tinc -n vpn add ConnectTo bar
197 tinc -n vpn export | gpg --clearsign | mail -s "My config" vpnmaster@example.com
200 The top command connects to a running tinc daemon and repeatedly queries its per-node traffic counters.
201 It displays a list of all the known nodes in the left-most column,
202 and the amount of bytes and packets read from and sent to each node in the other columns.
203 By default, the information is updated every second.
204 The behaviour of the top command can be changed using the following keys:
207 Change the interval between updates.
210 key, enter the desired interval in seconds, followed by enter.
211 Fractional seconds are honored.
212 Intervals lower than 0.1 seconds are not allowed.
214 Toggle between displaying current traffic rates (in packets and bytes per second)
215 and cumulative traffic (total packets and bytes since the tinc daemon started).
217 Sort the list of nodes by name.
219 Sort the list of nodes by incoming amount of bytes.
221 Sort the list of nodes by incoming amount of packets.
223 Sort the list of nodes by outgoing amount of bytes.
225 Sort the list of nodes by outgoing amount of packets.
227 Sort the list of nodes by sum of incoming and outgoing amount of bytes.
229 Sort the list of nodes by sum of incoming and outgoing amount of packets.
231 Show amount of traffic in bytes.
233 Show amount of traffic in kilobytes.
235 Show amount of traffic in megabytes.
237 Show amount of traffic in gigabytes.
