In the [Investigation](https://git.lattuga.net/netico/code-library/src/master/Network/Investigation) folder you can find a **bash** script to analyze **active TCP connections** on a **GNU/Linux** system.

## [anarres](anarres)
### How to avoid censorship at the DNS level?
[**Tor**](https://www.torproject.org/) provides a built-in **DNS forwarder**.
This is a minimal **Docker** container that uses a local caching DNS server ([**dnsmasq**](https://dnsmasq.org)) which will compensate for **TorDNS** being a little slower than traditional DNS servers.
### Usage
Build it using:
docker build --pull --rm -f Dockerfile -t anarres:latest .
Run it using:
docker run --rm -d -p 53:53/udp anarres:latest
Test it using:
dig @127.0.0.1 cr.yp.to
Expected output:
; <<>> DiG 9.11.5-P4-5.1+deb10u6-Debian <<>> @127.0.0.1 cr.yp.to
