Shadowsocks is a

Secure Shell (SSH) tunnel. Once connected, internet traffic can then be directed through the proxy.[9] Unlike an SSH tunnel, shadowsocks can also proxy User Datagram Protocol
(UDP) traffic.

Takedown

On 22 August 2015, "clowwindy" announced in a

distributed-denial-of-service attack targeting GitHub which occurred several days later.[15] Danny O'Brien, from Electronic Frontier Foundation, published a statement on the matter.[16]

Despite the takedown, collaborators of the project have continued the development of the project.

Server implementations

The original Python implementation can still be installed using the Pip Python package manager, but the contents of its GitHub repository have been removed.[17][18] Other server implementations include one in Go, Rust, and C using the libev event loop library; C++ with a Qt GUI; and Perl. The Go and Perl implementations are not updated regularly and may have been abandoned.[18][19][20][21]

Client implementations

All of the server implementations listed above also support operating in client mode. There are also client-only implementations available for Windows (shadowsocks-win), macOS (ShadowsocksX-NG), Android (shadowsocks-android), and iOS (Wingy).

proxifiers
, such as Proxycap, support Shadowsocks directly, thus avoiding the need for a Shadowsocks client, but some require a client.

Net::Shadowsocks

Net::Shadowsocks is name of the Perl implementation of Shadowsocks protocol client and server available on CPAN.[23]

ShadowsocksR

ShadowsocksR is a

License by not having the source code of the C# client available.[24] It was also criticized for its solution to the alleged security issues in the source project. Shadowsocks is currently under development, while development of ShadowsocksR has stopped.[25]

Similar projects

Shadowsocks is similar to The Tor Project's Pluggable Transport (PT) idea. PT makes it hard for Internet Service Providers to detect Tor traffic. They also both use a socks proxy interface. Whereas Shadowsocks is simpler, Obfs4 used in PT is more obfuscated.[26] Unlike Obfs4, Shadowsocks is not resistant to Active Probing.[27] The most similar PT to Shadowsocks is Obfs3.
