============
NAME
----
ss-tunnel - shadowsocks tools for local port forwarding, libev port
SYNOPSIS
--------
*ss-tunnel*
[-AuUv6] [-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>] [-n <nofile>]
[-L addr:port] [--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-tunnel`(1) is a tool for local port forwarding.
See 'OPTIONS' section for special option needed by `ss-tunnel`(1).
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 21 different ciphers:
+
table, rc4, 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, cast5-cfb, des-cfb,
idea-cfb, rc2-cfb, seed-cfb, 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.
-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-tunnel` 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.
-6::
Resovle hostname to IPv6 address first.
-L <addr:port>::
Specify destination server address and port for local port forwarding.
+
Only used and available in tunnel mode.
--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.
