Troubleshooting WireGuard connections

[Jason A. Donenfeld]

Hi Riccardo,

That's a confusing result. The tcpdump also shows two sequences of
completed handshakes happening, about 7 seconds apart. It might be
best in the end to hop onto IRC next week, and we can debug this in
real time. But based on the erratic behavior, my only guess remaining
is that you've mixed up the public and private keys -- perhaps sharing
a private key amongst hosts -- and so one session is interrupting the
handshake of another? Hmm...
