SYNOPSIS
--------
*ss-local*
 [-Auv] [-h|--help]
 [-s <server_host>] [-p <server_port>] [-l <local_port>]
 [-k <password>] [-m <encrypt_method>] [-f <pid_file>] [-t <timeout>]
 [-c <config_file>] [-b <interface>] [-a <user_name>]
 [-n <nofile>] [--fast-open] [--acl <acl_config>] [--mtu <MTU>]

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>::
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.

-U::
Enable UDP relay and disable TCP 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.

--mtu <MTU>::
Specify the MTU of your network interface.

--mptcp::
Enable Multipath TCP.
+
Only available with MPTCP enabled Linux kernel.

-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
....
