Re: Analyzing TOR-exitnodes for anomalies

Hash: RIPEMD160

I am not adding anything useful, but I wish to add my feeling about this
situation that people are so rapidly responding to a threat so early.

:) tor will never die if people like you all are on it. (which reminds
me i've blathered about writing a dns proxy patch for tor so dns leaks
are a thing of the past, and i bloody better do something serious about

dns poisoning is of course a bigger problem than tor, there has been
discussion about the 'splitting of the root' some months ago as it turns
out that dns servers will give out different addresses depending on the
nation of locality. This is a very serious problem and extends beyond
the domain of the tor network. I have no idea where to point people with
regard to this subject but I hope someone who has a bee in their bonnet
about it will very shortly.
