My v3 tree switched to 3.1 now, so not so easy ;-( I really need
to work out a way to do automated builds (switching sdkconfig
appropriately).

<div class="">I think you may be correct - it is probably not the
listen socket that has the issue, but the actual connection
socket.</div>
<div class=""><br class="">
</div>
<div class="">Can you try enabling the option SO_REUSEADDR in
menuconfig? That should allow the listen socket to be opened,
even if a connection socket is in TIME_WAIT state (assuming the
mongoose library sets SO_REUSEADDR correctly).</div>

<br class="">
It doesn't out of the box, as it still assumes LWIP does not support
it, but after disabling the exclusion in mg_open_listening_socket()
this works.<br class="">
<br class="">
So, another patch for mongoose… maybe we really should fork
mongoose. If you don't have an objection, I can do that later on.<br class="">

I've compared my LWIP config, only difference was I had

The bind has to occur in

<pre class="" wrap="">Mark,
Back in November we discussed this problem of the client's half of the
connection being left open. Then as now, you commented that mongoose
sends a close event (MG_EV_CLOSE) for each open connection when the
interface went down.
It does send a close event, but not until after the wifi is already
shut down so closing the socket at that point does not send any packet
to the client. I decided to punt on that issue, though, because
manually shutting down wifi is not an important use case. The more
likely case is that wifi connectivity is lost due to motion or other
causes and in that case no close packet can be delivered anyway.
I interpreted Michael's message to be referring to a problem with
ports on the server (OVMS) end. That is, to say that mongoose didn't
clean up LWIP state properly. Michael, can you explain a bit more?

But ssh client connection is still up on my workstation. Looks like

MDNS exits quicker because it responds to the network.wifi.down message, while ssh uses the network.mgr.stop event. In a clean shutdown there is a difference.
Perhaps we should issue network.mgr.stop earlier? However, even if we close the connections from our end, I’m not sure if the packet would make it through to the other end before the wifi disconnects.
Regards, Mark.
