Hello All!
I've got weewx running on an rPi3, and I have the interceptor set up. All
starts correctly, and the port is open, etc. The issue is that none of the
packet collection methods seems to work. I am receiving error 400 from both
tcpdump as well as ngrep commands that are piped to nc:
# tcpdump -i eth0 dst port 80 | nc 127.0.0.1 9999
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes

Here's an example from ngrep:
~~~
ngrep -l -q -d eth0 '0004a369e0d6'|nc localhost 9999
<head>
<title>Error response</title>
</head>
<body>

<p>Error code 400.
<p>Message: Bad request version ('(192.168.1.0/255.255.255.0)').

One of the things I'm unsure of is the format of the data expected by
Interceptor. There aren't notes besides how to install, and how to lightly
configure the device. I was working with Matthew on some of those things,
and got it running on a non-standard port, which was good, but now I don't
seem to be able to get it the last mile (to collecting actual data). I've
been playing with the individual commands used to collect the packets,
because Matthew's examples are for 'www.acurite.com' and Oregon Scientific
is using AWS nodes for their cloud hosting. The plaintext mac address ngrep
command returns nice, clean data:
~~~
T 192.168.1.73:3555 -> 54.228.205.96:80 [AP]
mac=0004a369e0d6&id=90&rid=d0&pwr=0&gw=0&av=0&wd=270&wg=0.9&ws=0.0&ch=1&p=1
T 192.168.1.73:3556 -> 54.228.205.188:80 [AP]

But something still seems to be wrong.
Any help that can be offered would be greatly appreciated.
Thanks!
