In tinc 1.1, if you want human readable information you can use the "tincctl
info" command. The result is something like this:

[root at foo]~>tincctl info bar
Node:         bar
Address:      192.0.43.10 port 655
Online since: 2012-12-03 09:03:36
Status:       validkey visited reachable udp_confirmed
Options:      pmtu_discovery clamp_mss
Protocol:     17.0
Reachability: directly with UDP
PMTU:         1459
Edges:        baz foo quux
Subnets:      10.0.0.42/32 fec0:0:0:0:0:0:0:42/128

And to see real-time traffic statistics, use "tincctl top":

[root at foo]~>tincctl top
Tinc                   Nodes:    4  Sort: name        Current

Node                IN pkts   IN bytes   OUT pkts  OUT bytes
bar                      15        998         48      63216
baz                       0          0          0          0
foo                      48      63216         15        998
quux                      0          0          0          0

With the latest version of the 1.1 branch from git, you can now do:

tincctl dump reachable nodes

That is not a well-defined question. Better questions are: "is node X
reachable" or "are there more than N nodes reachable". But now you can get the
answer with the command mentioned above and grep or wc.
