## How to compile
|
2022-08-22 13:33:56 +02:00
|
|
|
|
|
|
|
|
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
|
2022-08-21 22:48:40 +02:00
|
|
|
```
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
```

## Data source

|
The list of Google services IP addresses can be found on [this Google

support page](https://support.google.com/a/answer/10026322?hl=en).

|
addresses.
