Integrate support for plugin simple-obfs

[ortonomy]

One of the leading distributors of a package for using Shadowsocks servers Streisand has just merged a PR that enables the simple-obfs plugin by default.
(https://github.com/shadowsocks/simple-obfs AND StreisandEffect/streisand#743)

It's said this plugin helps defeat local QOS by ISPs, and could be very useful in China.

On iOS, Shadowrocket supports simple-obfs settings, can you integrate this into Shadowsocks-NG for Mac OS?

as @ortonomy said, not only OSX iOS clients, but also Android clients now support simple-obfs configuration through some kind of Plugin mechanisms.

fyi, Homebrew for mac os has binaries already built for shadowsocks-libev[1] and simple-obfs[2].

@nilbot thanks. basically, we could start simple-obfs under stand-alone mode for now before ShadowsocksX-NG gets supported

[ortonomy]

@nilbot - yes, this has always been the case. We know that ss-libev has the simple-obfs plugin support, but Shadowsocks-NG has the ss-libev without the plugin.

That's why we're asking for it to be integrated. Using a CLI for a service you turn on and off several hundred times a day can be pretty annoying, compared to a taskbar utility.

Well, I have already used simple-obfs standalone version before the supporting. Hoping this plugin will be integrated to this project!

@qiuyuzhou I think these are needed if implement this using SIP003:

• Get the prebuilt obfs-local binary and necessary dependencies from Homebrew, and let SSX-NG extract them to Application Support/ShadowsocksX-NG just like ss-local and privoxy do.
• Add two text fields to the server profile: Plugin and Plugin Options.
• Add --plugin PLUGIN and --plugin-opts PLUGIN_OPTIONS to the ss-local command line arguments if the corresponding value in the server profile is not empty, and make sure obfs-local is accessible for ss-local (this simplest solution is putting them in the same directory).
• For the profile QR code, SIP002 URI scheme encodes plugin settings like this: ss://[email protected]:8888/?plugin=obfs-local%3Bobfs%3Dhttp#Example2. Detailed description can be found here.

Then we can enable simple-obfs by filling Plugin with obs-local and Plugin Options with something like obfs=http;obfs-host=www.baidu.com.

FYI:

• SS-libev 3.0.5 already supports SIP003, so no upgrade to ss-local is needed.
• For SIP003 plugin, no plugin chaining is allowed (see this comment for rationalization). That means the Kcptun plugin won't coexist with simple-obfs. Maybe disabling the existing Kcptun options when SIP003 plugin is enabled is a better choice.

@timothyqiu
Current kcptun implement in ng is not by plugin system of shadowsocks-libev. So there is no plugin chain limiting.

[timothyqiu]

Just noticed that SS-libev 3.0.5 supports plugin and plugin-opts fields in the server JSON config, so there's no need to modify the command line arguments.

@qiuyuzhou -- this is getting quite a lot of attention. Are you going to work on this / put this in your roadmap?

[Kaijun]

@ortonomy I saw @timothyqiu has already sent a PR
