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.


-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 18 different ciphers: table, rc4, rc4-md5, aes-128-cfb, aes-192-cfb, aes-256-cfb, bf-cfb, camellia-128-cfb, camellia-192-cfb, camellia-256-cfb, cast5-cfb, des-cfb, idea-cfb, rc2-cfb, seed-cfb, salsa20, chacha20 and chacha20-ietf. The default cipher is table.

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.
-i interface
Send traffic through specific network interface.

For example, there are three interfaces in your device, which is lo (, eth0 ( and eth1 ( Meanwhile, you configure ss-manager to listen on 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.

Enable UDP relay.
Enable UDP relay and disable TCP relay.
Enable onetime authentication.
-d addr
Setup name servers for internal DNS resolver (libudns). The default server is fetched from /etc/resolv.conf.
Enable TCP fast open.

Only available with Linux kernel > 3.7.0.

--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.

Enable verbose mode.
-h, --help
Print help message.


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 a pong:


Then ss-manager(1) will send back the traffic statistics:

    stat: {"8001":11370}


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 -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.
