Thanks you Robert. I try it.
I have set an AP, and this time I see the flow of data between my station
and wunderground.com :
37 130.019998 10.42.0.13 34.232.250.77 HTTP 402 GET

Transmission Control Protocol, Src Port: 53970, Dst Port: 80, Seq: 1, Ack:
1, Len: 349
Source Port: 53970
Destination Port: 80
I perform a first modification with port setting :
[Interceptor]
driver = user.interceptor
iface = wlan0
port = 53970
pcap_filter = src 10.42.0.13
Weewxd run, as well weewx, but no data are obtained. I discover that the
port is dynamically set (next connexion, it is 53971, and so one.
But, if a don't set the port, weewx did not start with the following error :
ERROR weewx.engine: Import of driver failed: [Errno 13] Permission non
accordée (<class 'PermissionError'>)
I read the page of permissions
<https://github.com/weewx/weewx/wiki/Understanding-permissions#how-to-fix-network-permissions>
and
allowing no method seams easy, especially as the port used by my pws is
upper than 1024, the simpler will be to listen all the port upper than
1024, or some thing like this. But I have till now not found how to set
that filter. Any help will be welcome !
