Leaford is in China!!!!....V4L Is Gonna Rock Your World!!!

They do deep stateful packet inspection. If it won't go via FTP or http post, it won't go by email either. I've been tricky enough in the past to zip it (which doesn't help), then yoink the header off the zip. Then write an application for the recipient that concatenates the header and payload.

I think if you send it through gmail it should be fine. hell, you should be able to use picassa to get them uploaded to the net, then view them anywhere else you like...
To be honest, I'd always thought china would block incoming traffic - or more specifically, access to specific sites, or do a blanket lockdown on internet, I wasn't aware they prevented individual file transfer to a server outside of the country.
Cant find anything on a quick search, but it was a quick one To mask a files contents, a simple encrypted zipfile will do that, but if I was writing a block system that needed to prevent certain types of data being transferred, then I'd be blocking anything I didn't recognize.
The amusing thing is - well, we all remember dialup, right? we know data can be transferred over a telephone call? Leaford can telephone america, right? so it can't be that hard to get data out A littile bit of overkill perhaps, I'd just stick with reccomending trying picasa see if that works.

Naw, you can't upload it to gmail.

They don't want to facilitate free communication - and you don't want atrocities getting out to the rest of the world.

Is there any reporting done on this (ie by a journalist who has visited the place and researched it all?) available on the web anywhere that you know of?

Empirical Analysis of Internet Filtering in China

BBC NEWS | Technology | China's battle to police the web

Honestly - I don't know how you could NOT find info. Your search strategy must have had a pretty fatal flaw somewhere... just: china filtering the internet on google returns like 3.5million results. The first link I gave you ended-up in a UN report on the empirical data for China's filters - per the UN: http://unpan1.un.org/intradoc/groups/public/documents/apcity/unpan011043.pdf

Ahh I had no problems finding stuff about china blocking the net from the chinese, just nothing about them blocking outgoing. As it was reading to me they basically have a massive firewall type setup to keep out information they don't want their people to see.
With that in mind, anything you can still access, if you upload a file it could be seen anywhere else in the world... information out isn't teh same as information in, it's a lot harder to manage.

Just read through the links, they are all about china blocking access yo sites it doesn't approve of, but nothing about uploading or sending files to sites that aren't blocked, and nothing at all about emailing out files (Although it does say incoming emails are scanned)
Assuming web email clients (such as yahoo and gmail) are not blocked, then emailing out files should be a cinch. Is there something I'm missing?

I mean clearly, Leaford is having problems getting files out, and I actually do usually understand enough about the net and it's aspects that I may be able to come up with a simple solution, I just don't see what the issue is aside for some sites being blocked?

Might skim it again. In the first few lines they specifically cover both inbound and outbound within the empirical data.

Inbound, outbound, it's all the same. It's just stateful deep inspection. Trivial to implement, impossible to implement well.

The big boys (google, yahoo, et-al) are voluntarily censoring to keep from being force-censored. It really is a problem.

In fact, during the olympics there was a big bruhaha that reporters emails and uploads out of the country were being audited, edited, censored, and otherwise blocked and/or distorted. And that was after China agreed not to.

A simple solution is scp/sftp (tunneling over ssh). Well known to be working.

I've created accounts for him, and provided him with a GUI client for the Mac. Hopefully he should be coming online soon. It's around 0800/0900 depending upon where he is in country.

which article, I cant even found 'outbound' in a full page search aside for one instance in teh pdf which isn't a potential change, not a current situation, and even if it were put in place would only affect spoofed attempts
