       obfs-local - simple-obfs client

SYNOPSIS

       obfs-local [-6] [-h|--help] [-s <server_host>] [-p <server_port>] [-l <local_port>] [-f
       <pid_file>] [-t <timeout>] [-c <config_file>] [-i <interface>] [-a <user_name>] [-b
       <local_address] [-n <nofile>] [--fast-open] [--obfs <http|tls>] [--obfs-host <hostname>]

DESCRIPTION

       Obfs-simple is a very simple obfuscating tunnel tool.

       Obfs-simple is written in pure C and takes advantage of libev to achieve both high
       performance and low resource consumption.

       Obfs-simple consists of two components. obfs-local(1) works as a standard tunnel on local
       machines to obfuscate TCP traffic.

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.

       -a <user_name>
           Run as a specific user.

       -f <pid_file>
           Start obfs-simple 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.

       -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 obfs-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.

       -6
           Resovle hostname to IPv6 address first.

       --fast-open
           Enable TCP fast open.

           Only available with Linux kernel > 3.7.0.

       --mptcp
           Enable Multipath TCP.

           Only available with MPTCP enabled Linux kernel.

       --obfs <http|tls>
           Enable HTTP or TLS obfuscating. (Experimental)

       --obfs-host <hostname>
           Specify the hostname for obfuscating. (Experimental)

       -v
           Enable verbose mode.

       -h|--help
           Print help message.

EXAMPLE

       obfs-local(1) can be started from command line and run in foreground. Here is an example:

           # Start obfs-local with given parameters
           obfs-local -s example.com -p 12345 -l 1080 --obfs http --obfs-host www.baidu.com
