|
|
Nodes are colored according to their reachability:
|
|
red nodes are unreachable, orange nodes are indirectly reachable, green nodes are directly reachable.
|
|
Black nodes are either directly or indirectly reachable, but direct reachability has not been tried yet.
|
|
.It info Ar node | subnet | address
|
|

.Nm tincctl .
|
|
.It retry
|
|
Forces
|
|
.Xr tincd 8
|
|
to try to connect to all uplinks immediately.
|
|
Usually
|
|
.Xr tincd 8
|
|
attempts to do this itself,
|
|
but increases the time it waits between the attempts each time it failed,
|
|
and if
|
|
.Xr tincd 8
|
|
didn't succeed to connect to an uplink the first time after it started,
|
|
it defaults to the maximum time of 15 minutes.
|
|
.It disconnect Ar NODE
|
|
Closes the meta connection with the given
|
|
.Ar NODE .
|
|
.It top
|
|
If
|
|
.Nm
|
|
is compiled with libcurses support, this will display live traffic statistics
|
|
for all the known nodes, similar to the UNIX
|
|
.Xr top 1
|
|
command.
|
|
See below for more information.
|
|
.It pcap
|
|
Dump VPN traffic going through the local tinc node in
|
|
.Xr pcap-savefile 5
|
|
format to standard output,
|
|
from where it can be redirected to a file or piped through a program that can parse it directly,
|
|
such as
|
|
.Xr tcpdump 8 .

Example of configuring tinc using
|
|
.Nm :
|

|
|
.Sh TOP
|
|
The top command connects to a running tinc daemon and repeatedly queries its per-node traffic counters.
|
|
It displays a list of all the known nodes in the left-most column,
|
|
and the amount of bytes and packets read from and sent to each node in the other columns.
|
|
By default, the information is updated every second.
|
|
The behaviour of the top command can be changed using the following keys:
|
|
.Bl -tag
|
|
.It Ic s
|
|
Change the interval between updates.
|
|
After pressing the
|
|
.Ic s
|
|
key, enter the desired interval in seconds, followed by enter.
|
|
Fractional seconds are honored.
|
|
Intervals lower than 0.1 seconds are not allowed.
|
|
.It Ic c
|
|
Toggle between displaying current traffic rates (in packets and bytes per second)
|
|
and cumulative traffic (total packets and bytes since the tinc daemon started).
|
|
.It Ic n
|
|
Sort the list of nodes by name.
|
|
.It Ic i
|
|
Sort the list of nodes by incoming amount of bytes.
|
|
.It Ic I
|
|
Sort the list of nodes by incoming amount of packets.
|
|
.It Ic o
|
|
Sort the list of nodes by outgoing amount of bytes.
|
|
.It Ic O
|
|
Sort the list of nodes by outgoing amount of packets.
|
|
.It Ic t
|
|
Sort the list of nodes by sum of incoming and outgoing amount of bytes.
|
|
.It Ic T
|
|
Sort the list of nodes by sum of incoming and outgoing amount of packets.
|
|
.It Ic b
|
|
Show amount of traffic in bytes.
|
|
.It Ic k
|
|
Show amount of traffic in kilobytes.
|
|
.It Ic M
|
|
Show amount of traffic in megabytes.
|
|
