TL;DR

• DNSP is very simple and useful tool to setup whitelisted or blacklisted dns proxy server.
• if you want to use with dockered image, this script will be a good starting point.

Author

• original dnsp code from https://github.com/gophergala/dnsp
• Jioh L. Jung: simple build up script for dockerized.

Basic

• if you use android tethering, masquerade makes client device's TTL decrease.

  • so Telco can detect what packet is used with tethering.

• this means that if your kernel doesn't decrease TTL with hop, telco can't detect tethering packet by TTL value.

  • but, there's another way to detect. however, I think that TTL is enough to use. maybe, maybe...

Logic

• bascially tethering use 'masquerade' and it use 'ip_forward'. and it is linux's net function.
• and, it count one hop. so ip_forward must obey ip specification. this means that decrease ttl with passing hop.
