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−local(1) works as a standard socks5 proxy on local machines to proxy TCP traffic. For more information, check out shadowsocks−libev(8).
−s <server_host>
Set the server’s hostname or IP.
−p <server_port>
Set the server’s port number.
−l <local_port>
Set the local port number.
−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.
Refer to shadowsocks−libev(8) CONFIG FILE section for more details.
−n <number>
Specify max number of open files.
Only available on Linux.
−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.
−b <local_address>
Specify local address to bind.
−u
Enable UDP relay.
−A
Enable onetime authentication.
−−fast−open
Enable TCP fast open.
Only available with Linux kernel > 3.7.0.
−−acl <acl_config>
Enable ACL (Access Control List) and specify config file.
−v
Enable verbose mode.
−h|−−help
Print help message.
ss−local(1) can be started from command line and run in foreground. Here is an example:
# Start
ss−local with given parameters
ss−local −s example.com −p 12345 −l
