About Googerteller
Googerteller makes a sound when the computer sends a packet to a Google service or a tracker listed in its configuration. It excludes Google Cloud customer addresses when identifying Google services.
It runs on Unix-derived systems such as Linux, OSX and FreeBSD by piping tcpdump output into the teller program, with an option on Linux to follow a single process using bpftrace. Tracker addresses are read from tracker.conf, and the audio channel and frequency per tracker can be set in teller.conf. Use requires a compiled binary, dependencies including a C++ compiler, CMake, libpcaudio and tcpdump, and sudo access.

- Plays sound when packet sent to Google service or tracker
- Excludes Google Cloud customer addresses from Google service detection
- Configurable left/right channel and frequency per tracker
- Tracks single Linux process via bpftrace filtering
- Reads tracker IP addresses from editable tracker.conf file
- Runs via tcpdump pipe on Unix-derived systems
Best for: People using Linux, OSX, or FreeBSD who want audible indication of connections to Google services and trackers.
Good for
- Open source under MIT license
- Distinguishes Google services from Google Cloud customer addresses
