Modified from [SagerNet/v2ray-core](https://github.com/SagerNet/v2ray-core). #### Extends all features of SagerNet/v2ray-core ### Changes - embed ShadowsocksR plugin for shadowsocks ```json { "outbounds": [ { "protocol": "shadowsocks", "settings": { ... "plugin": "shadowsocksr", "pluginArgs": [ "--obfs=", "--obfs-param=", "--protocol=", "--protocol-param=" ] } } ] } ``` - embed simple-obfs plugin for shadowsocks ```json { "outbounds": [ { "protocol": "shadowsocks", "settings": { ... "plugin": "obfs-local", "pluginOpts": "" } } ] } ``` - Re-enable ReadV ### License GPL v3 ### Credits This repo relies on the following projects: - [SagerNet/LibSagerNetCore](https://github.com/SagerNet/LibSagerNetCore) --- --- METRICS --- - Files Extracted: 5 - Estimated Token Budget: ~1740 tokens - Canonical Reference: https://codewiki.google/github.com/netchx/netch
