Overview
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-localto 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.
