fteproxy
========

[fteproxy][1] provides transport-layer protection to resist keyword filtering,
censorship and discriminatory routing policies.

Its job is to relay datastreams, such as web browsing traffic,
by encoding streams as messages that match a user-specified regular expression.

fteproxy is fast, free, open source, and cross platform. 
It works very well with [vimagick/openvpn][2](TCP mode).

In the following example, I will setup a server/client pair to connect www.google.com:80.

## Internet Censorship

### The problem

### The solution

![after](https://fteproxy.org/images/withfte.png)

## Create a docker-compose.yml

```yaml
server:
  image: vimagick/fteproxy
  ports:
    - "80"
  environment:
    - MODE=server
    - SERVER_IP=0.0.0.0
    - SERVER_PORT=80
    - PROXY_IP=www.google.com
    - PROXY_PORT=80
    - KEY=CB2FBA2BC70490526E749E01BB050F6B555964290DFF58CF24785B4A093F7B18

client:
  image: vimagick/fteproxy
  ports:
    - "9009:80"
  links:
    - server
  environment:
    - MODE=client
    - SERVER_IP=server
    - SERVER_PORT=80
    - CLIENT_IP=0.0.0.0
    - CLIENT_PORT=80
    - KEY=CB2FBA2BC70490526E749E01BB050F6B555964290DFF58CF24785B4A093F7B18
```

> To generate random key:  
> `xxd -u -p -c32 /dev/urandom | head -n1`

## Run fteproxy server/client

```bash
$ docker-compose up -d
Creating fteproxy_server_1...
Creating fteproxy_client_1...

$ docker-compose ps
Name                     Command               State           Ports
----------------------------------------------------------------------------------
fteproxy_client_1   /bin/sh -c /fteproxy/ftepr ...   Up      0.0.0.0:9009->80/tcp
fteproxy_server_1   /bin/sh -c /fteproxy/ftepr ...   Up      0.0.0.0:32768->80/tcp
```

## Test with curl

```html
$ curl http://localhost:9009/
