How to compile

First install libpcaudio (libpcaudio-dev) and build tools (cmake, build-essential), then:

cmake .
make

How to run:

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

And then cry.

Problems

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

sudo sysctl net.core.optmem_max=204800
