You need a C++ compiler like gcc-c++ and CMake for compiling the binary.

You also need to install libpcaudio (libpcaudio-dev on Debian/Ubuntu, pcaudiolib-devel on Fedora/Red Hat).

Then run:

cmake .
make

sudo tcpdump -n -l dst net 192.0.2.1/32 $(for a in $(cat goog-prefixes.txt); do echo or dst net $a; done)  |  ./teller 

Replace 192.0.2.1 with the IP address of your default gateway (e.g. your Internet router).

And then cry.

If tcpdump complains about Warning: Kernel filter failed: Cannot allocate memory, try this first:

sudo sysctl net.core.optmem_max=204800

The list of Google services IP addresses can be found on this Google support page.

Note that this splits out Google services and Google cloud user IP addresses.
