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
|

## Problems
|
|
|
|
|
If tcpdump complains about `Warning: Kernel filter failed: Cannot allocate memory`, try
|
|
|
|
|
this first:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
sudo sysctl net.core.optmem_max=204800
|
|
|
|
|
```

## Macos
|
|
|
|
|
You will need to install the pcaudio library:
|
|
|
|
|
https://github.com/espeak-ng/pcaudiolib#mac-os
|
|
|
|
|
In turn this needs automake installed (from xcode or brew). With that it is standard install
|
|
|
|
|
WIth libpcaudio in place, follow instructions above.
