Interceptor driver "cannot assign requested address" - noob here - thoughts?

[Kruse Ludington]

I have an Ambient WS-2902C with a console publishing to four places specified in the awnet app: 1. AmbientWeather.net; 2. Wunderground; 3. Weathercloud; and 4; Customized - to <IP ADDRESS OF MY RASPBERRY PI> on port 80 (both on the same network internal network) but the PI is having trouble loading the interceptor driver with weird error messages (probably something simple as I am a noob). As per the Interceptor installation instructions for this model state I should use device-type=observer and listen (as I am not intercepting), these are the error messages I am running into from the log - 

sudo /etc/init.d/weewx start

then here's the log info:

so, I also tried this for debugging:

pi@kruse-pi:~ $ PYTHONPATH=bin python3 /usr/share/weewx/user/interceptor.py --device=observer --mode=listen address=<IP ADDRESS OF THE CONSOLE> --port=80

And came up with this which is not very helpful!

Traceback (most recent call last):
  File "/usr/share/weewx/user/interceptor.py", line 302, in <module>
    import weewx.drivers
ModuleNotFoundError: No module named 'weewx'

????

A little help - any ideas?

Thank you!

You didn't literally type "<ip address of..." in those commands did you ?  How about telling us what you actually typed.   There's nothing scary in whatever your addresses are.  Your log snippet already told us one address anyway...

Re: your PYTHONPATH line, that looks wrong to me for a dpkg installation like you did... it should probably be /usr/share/weewx

I didn't get anywhere in a quick attempt of installing interceptor on a modern ubuntu which is all python3, with all kinds of issues trying to get the pcap library installed, but I ran out of time trying to get it to work.   I'm sure somebody else here who uses it will chime in with a more authoritative answer.....

1. choosing port 80 for the custom server to send/post to is not a smart choice as this port is already used by the local (RPi) web server (nginx, apache2, ...). You must choose a unique port e.g. 8000, 8080, ...

2. in weewx.conf you must not assign the port along with the ip address.
the entry should be:

ip_address = 192.168.0.29

only, no colon or port added - it's, however, not needed

below a working [Interceptor] section

# ------ start weewx.conf excerpt --------------------

[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, smarthub, or access
    #   observer - fine offset WH2600/HP1000/HP1003, ambient WS2902
    #   lw30x - oregon scientific LW301/LW302
    #   lacrosse-bridge - lacrosse GW1000U/C84612 internet bridge
    #   ecowitt-client - any hardware that uses the ecowitt protocol
    #   wu-client - any hardware that uses the weather underground protocol
    device_type = observer
     port = 8000
    iface = eth0
 # ---------- end excerpt weewx.conf ------------

if you use the WLAN interface of the RPi ("WiFi"), then use: iface = wlan0 instead of iface = eth0

(the last character is a zero !!)

You don't need to enter your IP address here, it's obviously the one of the RPi

the port (8000) should also be the same in the WS View / awnet app (customized server)

You can of course choose another number, however not 80 !

there (WS View, awnet) the IP address of your RPi has to be entered (NO http:// in front of the address !! - only the address)
the path has to show at least "/" - an empty path will keep the console from posting

good luck

Probably silly question, but does the interceptor stuff work for 'sniff' mode on a modern python3-only system ?   I got pretty much nowhere trying to get the prereqiosote libpcap stuff installed on debian10 or debian11 under python3, but it seems to install ok on debian10 under python2.
