In Tell HN: GitHub is partially blocked in IndiaGreenTunnel bypasses DPI (Deep Packet Inspection) systems found in many ISPs
2 points · Open discussionYou don't need VPNs to bypass censorship blocks in India. Well, at least in my experience.
Apps that manipulate TCP packets locally to break fingerprinting [0] like GoodbyeDPI (Windows) [1], GreenTunnel (cross platform CLI) [2], Intra (Android) [3] have been adequate.

In How to circumvent Sci-Hub ISP block> Greentunnel also breaks up your packets in such a manner that prevents SNI sniffing...
Yep, here's the code that does the trick: https://github.com/SadeghHayeri/GreenTunnel/blob/master/src/...
In Investigating TLS Blocking in IndiaJio uses DNS sniffing and SNI blocking.
They monitor all DNS requests(no matter who provides the DNS server). So the solution is DNS over HTTPS.
The SNI method is a bit tricky. ESNI does prevent the blocking, but currently it’s rarely implemented by websites. One other solution is TCP fragmentation. Split the packet containing SNI into two. This prevents them from catching the whole URL mentioned in the SNI. Thus, they are unable to block it.
One such tool: https://github.com/SadeghHayeri/GreenTunnel
