<div> <font face="Arial, Helvetica, sans-serif">Come'on my dude, of course if anybody's snarfing traffic and/or preventing anonymity it's China with their Deep Packet Inspecting Routers and what not. I'm told by a deep source that there is a way to integrate TOR, OTR, QQ and some other application which tunnels IP-through-DNS but since this isn't precisely my cup of tea I don't know much more than that. I think I recall them saying that this assumes a colluding server somewhere outside of the firewall, but I don't really know what I'm talking about. <br>
<br>
Shit, speaking of something related, I think I saw some academic paper by some stuffed shirt recently talking about something related to this. I wonder if I can find it...<br>

A user has e-mailed me off list to confirm he can reproduce my results<br>
w.r.t the strings ?, ?O, ?OT and ?OTR. This was using Adium 1.3.2 and<br>
Pidgin on Linux with OTR 3.1.0 on either end. As I've stated before<br>
there are issue with Pidgin + QQ on Windows so it would be helpful if<br>
someone with an up to date Pidgin + OTR on Linux could contact me to<br>
see if the results are replicated on Linux to Linux Pidgin clients.<br>
This could hopefully rule out a buggy QQ implementation in libpurple.<br>
<br>
As an aside, I entered the following terms and they were sent fine over<br>
the network even though reverse dns shows the QQ server I'm connected<br>
to is in China:<br>
<br>
Tibet<br>
Taiwan<br>
Falun Gong<br>
Democracy<br>
Tiananmen Square<br>
<br>
So if QQ are censoring they must be censoring in Mandarin not English,<br>
OTR strings aside.<br>
<br>
The ?OTR string use in OTR is definitely its biggest weakness. We<br>
currently have to rely on the goodwill of Microsoft / Yahoo / AOL /<br>
Google / Your Jabber admin not to block OTR. A weak point indeed.<br>
Other that OTR is probably one of the most useful privacy tools I've<br>
used (and continue to use)<br>
