Description
So what we lack testing for is ping-timeout reconnects with DCO involved
- --client side
- connect
- ping-timeout (30s)
(triggerable via
kill $CNon the server's management interface, or possibly via firewall rule in between - though timing is complicated if you want reconnect to succeed) - reconnect
- ping-timeout again (30s)
- eventually tls-renegotiate (300s)
and verify that pings through the tunnel are working all the time as one would expect this - fail while the server's instance is dead, but do not fail longer than 30-ish seconds.
Maybe also check the server's idea of "when did the client reconnect?" - which gives a good indication of "did ping-timeout actually work?".
The issue at hand is on FreeBSD, but I guess that having test coverage on Linux and Windows won't hurt either...
