76 is omitted, the default length will be 2048 bits.
77 When saving keys to existing files, tinc will not delete the old keys;
78 you have to remove them manually.

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