With tinc 1.0.x, that's hard to say. You could add a host-up script to
track when the last time a node was alive. With tinc 1.1, you can use
the "tinc info <node>" command to find out what the last time the node
went on- or offline is. However, both cases do not distinguish between
connections made via ConnectTo or via other means.
But most importantly, you don't need to have a ConnectTo line in your
tinc.conf for every node in your VPN! Say you have three nodes, A, B and
C, and A and B both have ConnectTo C in their tinc.conf, then A and B
will learn about each other from C, and will be able to exchange VPN
packets directly, without requiring further ConnectTo variables. If you
want to keep your configuration static and not have many ConnectTo
lines, then the best way is to choose a small number (say 3) of nodes
that are most likely to be online, and just have all the nodes ConnectTo
those 3 nodes.
In tinc 1.1, this can be fully automated: just add "AutoConnect = yes"
to tinc.conf, and then tinc will automatically create meta-connections
as necessary.
