NAME

       obfs-server - simple-obfs server

SYNOPSIS

       obfs-server [-v] [-h|--help] [-s <server_host>] [-p <server_port>] [-l <local_port>] [-r
       <addr>:<port>] [-f <pid_file>] [-t <timeout>] [-c <config_file>] [-i <interface>] [-a
       <user_name>] [-d <dns_addr>] [-n <nofile>] [-b <local_address] [--fast-open] [--mptcp]

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-server(1) works as a standard tunnel on
       remote 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.

       -a <user_name>
           Run as a specific user.

       -f <pid_file>
           Start simple-obfs 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-server 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.

       -d <addr>
           Setup name servers for internal DNS resolver (libudns). The default server is fetched
           from /etc/resolv.conf.

       --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)

       -v
           Enable verbose mode.

       -h|--help
           Print help message.

EXAMPLE

       It is recommended to use a config file when starting obfs-server(1).

       The config file is written in JSON and is easy to edit. Check out the SEE ALSO section for
       the default path of config file.

           # Start the obfs-server
           obfs-server -c /etc/simple-obfs/config.json
