Belarus finally bans Tor

#32I know very little of networking but I assume to perform a TCP reset injection attack, the ISP would need to rely on the IP address of the public onion routers. Now, why do they play around with the reset flag instead of just simply swallowing the packets directed at a tor router?
Because effectively blocking packets at requires supervising all routes through which they might escape (i.e., managing a lot of dynamic rules on a lot of very critical routers), whereas injecting forged packets only requires one little box.
Kinda like the Berlin Wall. Easier to shoot people attempting to cross than hermetically seal the entire border.

I don't quite follow. You can't inject an RST packet unless you know someone is trying to connect to a Tor node, so you still need to supervise all the routes, right?

#37This reminds me of a paper I read recently about the techniques that China employs to block Tor and other anonymity servers.
Great read, especially the annotated version: http://fermatslibrary.com/s/examining-how-the-great-firewall...

When I read your comment it made it seem like the WSJ was praising Belarus for banning Tor, which is not the case. (at least from reading the portion of the article that is not behind a paywall)

#39Could they use remote relays still?
The article says it's only direct connections to public relays that are being interrupted, so plain ordinary connections (ie. not even using a pluggable transport) to a bridge still works.

Wall Street Journal praising Belarus for banning Tor? How would that ever be possible?
