Who is the target audience of this software and how does it work? Do non technical users set this up on a VPS provider and then connect to it? I'd imagine most developers in China would just SSH tunnel their way out.

SSH dynamic port forwarding is no longer working for years. It is so easily picked up by GFW and minutes later it is gone together with the whole SSH connection. So does PPTP and L2TP VPN. GFW has been upgraded so many times for the past few years. The target audience is developers. The install is super simple via one line of `pip install`, the start code for daemon is also one line with the configuration inline or t…

setup a server with aliyun. the cloud service provider from alibaba. And relay the traffic from there.

Funny you mention it, we are actually uploading to the server in Aliyun cloud services. Completely unusable :(

I was visiting China recently (my first time there). I thought bypassing The Great Firewall was going to be as simple as an "ssh -D" SOCKS setup, or a "ssh -w" tunnel. Oh boy, I was wrong. If you try this, or even a basic OpenVPN setup, you will quickly find out your VPN works fine for about 5 minutes, but then latency increases to 5sec, 10sec, 30sec(!), and then everything times out. After some research I read onlin…

This might sound a bit counter intuitive but they really hate OpenVPN and SSH tunnels - not to mention they are trivial to detect and the process is highly automated. Traditional VPNs such as PPTP/IPsec as well as various forms of obfuscated proxies are generally not interfered with unless something major happens. A lot of the alleged "censorship" are actually symptoms of high latency and packet loss on home connecti…

How do multinational companies' china offices get through the firewall? For example if my company uses Google apps, how do I ensure that my china office has access?

I am in Iran , you cannot believe it , same here , They use deep packet inspection too, they will shut every package down. every open vpn , cisco vpn , etc connection will lose connection every 2-3 min . Connection to outside web is almost impossible. I have noticed they have multiple situation, for example when everything's quiet internet is not so bad (despite the fact bandwidth is extremely low for huge amount of…

I'm not sure but I suspect that they got the technology (hardware and software) from China too. As a Chinese netizen I don't know if I should be proud that we have world-class advanced technology or be ashamed. Possibly ashamed.
