NAME

ss-local - shadowsocks client as socks5 proxy, libev port

SYNOPSIS

ss-local [-uv6] [-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> ] [-a <user_name> ] [-b <local_address> ] [-n <nofile> ] [--fast-open] [--reuse-port] [--acl <acl_config> ] [--mtu <MTU> ] [--no-delay] [--plugin <plugin_name> ] [--plugin-opts <plugin_options> ] [--password <password> ] [--key <key_in_base64> ]

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-local (1) works as a standard socks5 proxy on local machines to proxy TCP traffic. For more information, check out shadowsocks-libev (8).

OPTIONS

-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> , --password <password>

Set the password. The server and the client should use the same password.

--key <key_in_base64>

Set the key directly. The key should be encoded with URL-safe Base64.

-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.

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 the local address to use while this client is making outbound connections to the server.

-u

Enable UDP relay.

-U

Enable UDP relay and disable TCP relay.

-6

Resovle hostname to IPv6 address first.

--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.

--mtu <MTU>

Specify the MTU of your network interface.

--mptcp

Enable Multipath TCP.

Only available with MPTCP enabled Linux kernel.

--no-delay

Enable TCP_NODELAY.

--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.

EXAMPLE

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 1080 -k foobar -m aes-256-cfb
