NAME

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:
