I did a restart tonight and weewx wouldn't start. Saw this in the logs and cannot figure out why this is happening. I checked all my configs and they are right, haven't touched then since last June.

weewx[5862]: engine: Import of driver failed: in method 'pcapObject_open_live', argument 2 of type 'char *' (<type 'exceptions.TypeE
rror'>)

Any ideas ?

Running the Interceptor manuall works just fine so I know it's not that....

PYTHONPATH=/usr/share/weewx python weewx-share/user/interceptor.py --device=observer --mode=sniff --iface=wlan0 --filter="src 10.3.141.62 and dst port 80"

did you do a system update?

what version of weewx is this, what version of python, and what version of the weewx-interceptor?

also, please post the [Interceptor] section of your weewx configuration file

I tried pycap and that did run for a few seconds.

so what *did* change between before the restart and after the restart?

this looks like a mistake in your weewx configuration file - weewx is trying to load a service called 'w' that does not exist?

I added a custom page to my skin and that was it. I removed the changes and attempted a restart and it still wouldn't run.

I just disabled that skin also and used a different skin and same error.

which version of interceptor were you last running successfully?

in june, the interceptor version was 0.46. the version became 0.49 with changes made in december 2019. as of 11jan2020, the version is 0.50.

did you do 'apt-get update' between when weewx was last running properly and now?

Honestly I don't remember what version of Interceptor I was running before. I did a update because like I said I hadn't messed with it since last June so it could have been .46

I did a apt upgrade after I couldn't get weewx running but non of those packages involved python.

Actually your driver I used was around Mar 8, 2019 because that's when I wrote the Hostapd doc.

that is probably what did it. sniffing depends on the pcap library, and doing an apt upgrade could very well have changed that.

the exception that is preventing the driver from loading is a TypeError. there is something odd about the second argument to pcapObject_open_live

I was getting that error BEFORE I did the upgrade though.

this is actually running just fine - when you ran it this time, there was no exception at pcapObject_open_live

so one time when you started weewxd, you got a type error for argument 2 of pcapObject_open_live. we do not know what caused that.

another time when you started weewxd, you got a failure because of a bogus service configuration in your weewx configuration file.

and one time when you ran interceptor directly, it worked.

you did an apt update, which might have updated your pcap library

you updated the interceptor driver

the pcap initialization code in the interceptor driver has not changed since january 2019.

so without more information, i'd guess that the failures are due to changes that you are making in your weewx configuration file.

if it is true that running interceptor directly works, but running weewxd fails, with absolutely no other changes, then run those two different ways to figure out what is different.

libpcap fails completely

engine: Import of driver failed: in method 'pcapObject_open_live', argument 2 of type 'char *' (<type 'exceptions.Type
Error'>)

All of this points to the weewx engine but non of it makes any sense because I can run interceptor standalone.

I really can't understand how any of this broke in a years time... I have done plenty of apt upgrades and nothing like this has ever happened and I have worked on my skin more then once and again no issues.

Guess running weewx is in the past now.... I have tried everything and it refuses to run.

no one can help you if you don't post it! try posting your weewx configuration file (the one that resulted in the 'engine: Loading service w' and 'ValueError: Empty module name' exception).

diagnosing these things is MUCH easier if you post the log and config right from the start.

sometimes just the act of doing that will let you see things that you missed

probably not relevant to the interceptor, but 'Inside Humidity' is not a valid parameter for the 'Calculations' stanza.

now with debug=1, start up weewx and post the log from startup until failure.

Just to make sure that this isn't a error caused by me I installed a fresh raspian and weewx with your driver and my Ambient connected to hostapd and the same error popped up for both libpcap and pypcap installed. All virgin here... the only change in that weewx.conf I made was changing the station type and adding hostpad to raspbian.

scott,

i still have no idea what changes you are making between runs, and which log output is associated with each change. it sounds like you are modifying the libpcap layer and the python pcap layer - i've seen at least two different pypcap versions in the log output (1.1 and 1.2.2).

never mind I have trashed weewx and will go on with something else. It worked for almost 3 years without a hitch.

It's pretty simple when you read...

python-libpcap is a debian package installed via apt. and python-pypcap is the other package. I posted both outputs from each different ways to supposedly run you driver and neither work anymore. Plain and simple. I tested on a virgin install of debian 9 for a raspberry pi 3B+ with only hostapd installed and weewx. I changed the station_type to Interceptor and added the wlan0 info. I then started weewx and same problem... I don't what to give you when just this simple test didnt work either.

Matt, did you ever get to the bottom of this issue?

I have just done an apt-get upgrade, which upgrade the pcap & weewx and ran into this same issue.

I have made sure I'm using the latest version of interceptor.

I'm regretting upgrading the entire system, rather than just the security updates...

Running the script directly works, so it is something todo with the Weewx - Interceptor link that isn't quite right.

Example output:

The issue appears to be with passing of the interface, as changing the default interface at line 310 of interceptor.py to the correct interface and not specifying the interface in the weewx.cfg results in it working.

For me this is what I changed it to:

310 DEFAULT_IFACE = 'wlan0'

Calling it a night, so hopefully that assists with tracking down the bug.

Did anyone find a fix for this?

I'm in the same boat. Fresh raspberry pi image, clean install.

Solved by uninstalling python3 and installing 2.7.

What did work for me was using pypcap instead of libpcap. So uninstall the recommended "python-libcacp" and install "python-pypcap" instead.
