Fixed. Thanks for the report.

[D-LucasAraujo]

How? I have the same problem

[karpierz]

Please try the latest release: pcap-ct 1.2.3b12

[D-LucasAraujo]

I'm a really really newbie, sorry. I was forgotten to execute the file setup.py ... This make all work !!! Thank you very much for the ansewr and sorry for my poor english, i'm a brazillian and my final project for my university is a network monitoring tool using libpcap. Professionals usually don't pay much attention to newbies.

[karpierz]

@D-LucasAraujo np :) Good luck with your studies! PS: Belevie me. My "English" is much worse than yours ;)

Best way to install libpcap is: python -m pip install -U pcap-ct It exist as package on the official pypi: Take a look at https://pypi.org/project/pcap-ct/

Hi @karpierz, good day. Can you give me a tip ?? I'm trying get a ip source address source of a packet. Is there a function for this in the library ?

[D-LucasAraujo]

Good night @karpierz, i noticed while studying your capture example that in the 'countme' function there are 2 parameters, pkd ​​and hdr. Could you give me a hint if it is possible to use these parameters to get the source ip of the package?
