Subject: BitTorrent Feature request


Due to traffic restrictions applied in our country, we would like to
create a feature in bittorrent tracker that allowed only certain IP
adresses to connect, (local adresses it is).

We downloaded the source code, but we had some difficulties to
understand it (first time with Python :P). We'd like to know if u
could give us some hints in how to do it (i mean what part of the
source should we change), or if there is a working java, c++, etc
port of bittorrent.

Answer 1

Modify (was around lines 207 - 210) to get an idea of how to reject certain IPs.

If you are feeling tricky, you could also hook into geoip to check that people were connecting from the same country.

Answer 2

Use linux and use iptables.

iptables is used to construct firewalls. It could be used to allow specific IP's on specific ports easily enough. Drop all others.

Probably a lot more ways to do this but this will work.

Answer 3

Setup some smart firewall rules to block external access. It doesn't have to be linux.
