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
