I my set up is an acurite smarthub, a raspberry pi 1 running weewx and
weewx-interceptor in sniff mode, port mirroring using netgear GS105Ev2.
I can't seem to get data into weewx.
I can run tcpdump on my router and see the packets. I can run tcpdump on
the raspberry pi and see packets.
but I am not getting any data into weewx:
from weewx.conf:
[Interceptor]
# This section is for the network traffic interceptor driver.
# The driver to use:
driver = user.interceptor
# Specify the hardware device to capture. Options include:
# acurite-bridge - acurite internet bridge
# observer - fine offset WH2600/HP1000/HP1003, aka 'observer'
# lw30x - oregon scientific LW301/LW302
# lacrosse-bridge - lacrosse GW1000U/C84612 internet bridge
device_type = acurite-bridge
mode = sniff
iface = eth0
pcap_filter = src 192.168.5.230 and dst port 80
pi@raspberrypiFB:~ $ tcpdump --version
tcpdump version 4.9.0
libpcap version 1.6.2
OpenSSL 1.0.1t 3 May 2016
If I run this line while I watch tcpdump on my router to ensure acurite
packets have been sent, I get nothing.

^C
16 packets captured
17 packets received by filter
0 packets dropped by kernel
nothing is coming out of combine-lines.pl when I try it:
sudo tcpdump -A -U -w - -i eth0 src 192.168.5.230 and port 80 |
/etc/weewx/weewx-interceptor-master/util/combine/combine-lines.pl
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size
262144 bytes
^C1922 packets captured
1922 packets received by filter
0 packets dropped by kernel
Is tcpdump getting all the packet? It seems like only part of the line is
there.
I assume I am missing something obvious, but I am quite frustrated and
don't know what to try next.
Thanks!
