shadowsocks-erlang

Totally asynchronous implementation of Shadowsocks in Erlang.

Original python version: https://github.com/clowwindy/shadowsocks

Usage

Compile

./rebar clean & ./rebar compile

Elang OTP(R16B01) and rebar are needed. crypto module in OTP improved a lot in R16B01, but unfortunately, the port which implement this module does not use EVP_* functions. Which means almost all the block cipher method is not compatible with other shadowsocks implementation. default and rc4 method works fine.
Client side

erl -smp auto -config ./local.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached
Server side

erl -smp auto -config ./remote.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached

Configuration

Config files

local.config, remote.config
Descriptions

     {shadowsocks,
     [
       {type, local},
       {local_port,1080},
       {server,"localhost"},
       {server_port,8388},
       {password,"barfoo!"},
       {method,default}
     ]}

{type, local} is for client, {type, remote} is for server side.

{error_logger, {file, "log/shadowsocks_client.log"}}, logs will be written in log/shadowsocks_client.log. If you don't want it, use {error_logger, silent} instead

TODOs

Check IPv6
anthor crypto module which port(in C) uses EVP_* interfaces.
