$ rebar3 compile

Usage

• start

    application:start(sserl).

• stop

    application:stop(sserl).

• start / update listener

If the port already started,the method, password and expiretime will be updated.

    Args = [{port, 8388}, {type, server}, {ota, false}, {method, "rc4-md5"},{password,"xx"}],
    sserl_listener_sup:start(Args).

• stop listener

    sserl_listener_sup:stop(8388)

Configuration

sserl support cuttlefish, you can easy configure with cuttlefish schema.

• cuttlefish files

  priv/sserl.schema

• env config

                  ],
                  [ %% other listeners
                    ...
                  ]
         ]},

         %% shadowsocks-panel integration support
         %% --------------------------------------
         {sync_enable, false},   %% enable synchronize users from ss-panel
         {sync_node_id, 1},      %% the node id on ss-panel
         {sync_mysql_host, "x-net.vip"}, 
         {sync_mysql_port, 3306},        
         {sync_mysql_db,   "ss-panel"}, 
         {sync_mysql_user, "root"},
         {sync_mysql_pass, "123456"},
         {sync_report_min, 1048576}    %% bytes threshold to report flow
     ]}

Cluster

sserl will share the flow data with joined cluster

• Start cluster

    mnesia_cluster:join('xx@xx.com').

• Leave cluster

    mensia_cluster:leave().

Events

%% flow event report: {report, Port, Download, Upload}
%% 
-define(FLOW_EVENT, sserl_flow_event).

%% stat event
%%      new listener {listener, new, Port}
%%      accept    :  {listener, accept, Addr, Port}
%%      open      :  {conn, open, Pid}
%%      close     :  {conn, close, Pid, Reason}
%%      connect   :  {conn, connect, Addr, Port}
%% 
-define(STAT_EVENT, sserl_stat_event).
