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

63 .It generate-ecdsa-keys
64 Generate public/private ECDSA keypair and exit.
65 .It generate-rsa-keys Op bits
66 Generate public/private RSA keypair and exit.
69 is omitted, the default length will be 2048 bits.
70 When saving keys to existing files, tinc will not delete the old keys;
71 you have to remove them manually.
73 Dump a list of all known nodes in the VPN.
75 Dump a list of all known connections in the VPN.
77 Dump a list of all known subnets in the VPN.

113 Dump VPN traffic going through the local tinc node in
115 format to standard output,
116 from where it can be redirected to a file or piped through a program that can parse it directly,
121 Examples of some commands:
122 .Bd -literal -offset indent
123 tincctl -n vpn dump graph | circo -Txlib
124 tincctl -n vpn pcap | tcpdump -r -
128 The top command connects to a running tinc daemon and repeatedly queries its per-node traffic counters.
129 It displays a list of all the known nodes in the left-most column,
130 and the amount of bytes and packets read from and sent to each node in the other columns.
131 By default, the information is updated every second.
132 The behaviour of the top command can be changed using the following keys:
135 Change the interval between updates.
138 key, enter the desired interval in seconds, followed by enter.
139 Fractional seconds are honored.
140 Intervals lower than 0.1 seconds are not allowed.
142 Toggle between displaying current traffic rates (in packets and bytes per second)
143 and cummulative traffic (total packets and bytes since the tinc daemon started).
145 Sort the list of nodes by name.
147 Sort the list of nodes by incoming amount of bytes.
149 Sort the list of nodes by incoming amount of packets.
151 Sort the list of nodes by outgoing amount of bytes.
153 Sort the list of nodes by outgoing amount of packets.
155 Sort the list of nodes by sum of incoming and outgoing amount of bytes.
157 Sort the list of nodes by sum of incoming and outgoing amount of packets.
159 Show amount of traffic in bytes.
161 Show amount of traffic in kilobytes.
163 Show amount of traffic in megabytes.
165 Show amount of traffic in gigabytes.
