NAME¶ss-manager - ss-server controller for multi-user management and traffic statistics
SYNOPSIS¶ss-manager [-AuUv] [-h|--help] [-s <server_host>] [-p <server_port>] [-l <local_port>] [-k <password>] [-m <encrypt_method>] [-f <pid_file>] [-t <timeout>] [-c <config_file>] [-i <interface>] [-b <local_addr>] [-a <user_name>] [--manager-address <path_to_unix_domain>] [--executable <path_to_server_executable>] [--fast-open] [--reuse-port] [--plugin <plugin_name>] [--plugin-opts <plugin_options>]
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.
Shadowsocks-libev accepts 18 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, salsa20, chacha20 and chacha20-ietf.
The default cipher is rc4-md5.
If built with PolarSSL or custom OpenSSL libraries, some of these ciphers may not work.
You may use "port_password" field inside this configuration file to bring up multiple ss-server instances together.
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.
Only available with Linux kernel > 3.7.0.
Only available with Linux kernel > 3.9.0.
Only available in server and manager mode.
Only available in manager mode.
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):
To add a port:
To remove a port:
To receive a pong:
Then ss-manager(1) will send back the traffic statistics:
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.
