DESCRIPTION

       Shadowsocks-libev is a lightweight and secure socks5 proxy. It is a port of the original
       shadowsocks created by clowwindy. Shadowsocks-libev is written in pure C and takes
       advantage of libev to achieve both high performance and low resource consumption.

       Shadowsocks-libev consists of five components. ss-manager(1) is a controller for
       multi-user management and traffic statistics, using UNIX domain socket to talk with
       ss-server(1). Also, it provides a UNIX domain socket or IP based API for other software.
       About the details of this API, please refer to the following PROTOCOL section.

OPTIONS

       -s <server_host>
           Set the server’s hostname or IP.

       -k <password>
           Set the password. The server and the client should use the same password.

       -m <encrypt_method>
           Set the cipher.

           Shadowsocks-libev accepts 19 different ciphers:

           aes-128-gcm, aes-192-gcm, aes-256-gcm, rc4-md5, aes-128-cfb, aes-192-cfb, aes-256-cfb,
           aes-128-ctr, aes-192-ctr, aes-256-ctr, bf-cfb, camellia-128-cfb, camellia-192-cfb,
           camellia-256-cfb, chacha20-ietf-poly1305, xchacha20-ietf-poly1305, salsa20, chacha20
           and chacha20-ietf.

           The default cipher is chacha20-ietf-poly1305.

           If built with PolarSSL or custom OpenSSL libraries, some of these ciphers may not
           work.

       -a <user_name>
           Run as a specific user.

       -f <pid_file>
           Start shadowsocks as a daemon with specific pid file.

       -t <timeout>
           Set the socket timeout in seconds. The default value is 60.

       -c <config_file>
           Use a configuration file.

           You may use "port_password" field inside this configuration file to bring up multiple
           ss-server instances together.

       -i <interface>
           Send traffic through specific network interface.

           For example, there are three interfaces in your device, which is lo (127.0.0.1), eth0
           (192.168.0.1) and eth1 (192.168.0.2). Meanwhile, you configure ss-local to listen on
           0.0.0.0:8388 and bind to eth1. That results the traffic go out through eth1, but not
           lo nor eth0. This option is useful to control traffic in multi-interface environment.

       -u
           Enable UDP relay.

       -U
           Enable UDP relay and disable TCP relay.

       -A
           Enable onetime authentication.

       -d <addr>
           Setup name servers for internal DNS resolver (libc-ares). The default server is
           fetched from /etc/resolv.conf.

       --fast-open
           Enable TCP fast open.

           Only available with Linux kernel > 3.7.0.

       --reuse-port
           Enable port reuse.

           Only available with Linux kernel > 3.9.0.

       --acl <acl_config>
           Enable ACL (Access Control List) and specify config file.

       --manager-address <path_to_unix_domain>
           Specify UNIX domain socket address for the communication between ss-manager(1) and
           ss-server(1).

           Only available in server and manager mode.

       --executable <path_to_server_executable>
           Specify the executable path of ss-server.

           Only available in manager mode.

       --executable <path_to_server_executable>
           Specify the working directory of ss-manager.

           Only available in manager mode.

       --plugin <plugin_name>
           Enable SIP003 plugin. (Experimental)

       --plugin-opts <plugin_options>
           Set SIP003 plugin options. (Experimental)

       -v
           Enable verbose mode.

       -h|--help
           Print help message.

PROTOCOL

       ss-manager(1) provides several APIs through UDP protocol:

       Send UDP commands in the following format to the manager-address provided to
       ss-manager(1):
           command: [JSON data]

       To add a port:
           add: {"server_port": 8001, "password":"7cd308cc059"}

       To remove a port:
           remove: {"server_port": 8001}

       To receive the traffic statistics:
           ping

       The format of the traffic statistics:
           stat: {"8001":11370}

       There is no way to reset the traffic statistics, unless you remove the port and add it
       again

EXAMPLE

       To use ss-manager(1), First start it and specify necessary information.

       Then communicate with ss-manager(1) through UNIX Domain Socket using UDP protocol:

           # Start the manager. Arguments for ss-server will be passed to generated
           # ss-server process(es) respectively.
           ss-manager --manager-address /tmp/manager.sock --executable $(which ss-server) -s example.com -m aes-256-cfb -c /path/to/config.json

           # Connect to the socket. Using netcat-openbsd as an example.
           # You should use scripts or other programs for further management.
           nc -Uu /tmp/manager.sock

       After that, you may communicate with ss-manager(1) as described above in the PROTOCOL
       section.
