As Fredrik Bjork also pointed out, you are using the same Subnet for
both machines. The Subnet lines tell tinc which IP addresses belong to
which host. If you make them the same, tinc will not know to which of
the two hosts it has to send the packet.

If you have only two computers which you want to connect, then use
"Subnet = 10.0.0.1/32" for Server and "Subnet = 10.0.0.3/32" for
Client.

The segmentation faults and net2str() errors are caused by a bug in tinc
which is triggered when two hosts use exactly the same Subnet. I will
fix this shortly.
