Pingtunnel is a tool that send TCP/UDP traffic over ICMP.
|
pingtunnel是把tcp/udp/sock5流量伪装成icmp流量进行转发的工具。用于突破网络封锁，或是绕过WIFI网络的登陆验证，或是在某些网络加快网络传输速度。
|
||||||
|
|
||||||
## Note: This tool is only to be used for study and research, do not use it for illegal purposes
|
**注意：本工具只是用作学习研究，请勿用于非法用途！**
|
||||||
|
<br />Pingtunnel is a tool that advertises tcp/udp/sock5 traffic as icmp traffic for forwarding. Used to break through the network blockade, or to bypass the WIFI network login verification, or speed up network transmission speed on some networks.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
## Usage
|
# Why use this
|
||||||
|
* 因为网络审查，ip会直接被ban，但是却可以ping通，这时候就可以用这个工具继续连接服务器。If the server's ip is blocked, all tcp udp packets are forbidden, but it can be pinged. At this point, you can continue to connect to the server with this tool.
|
||||||
### Install server
|
* 在咖啡厅或是机场，可以连接free wifi，但是需要登录跳转验证，这时候就可以用这个工具绕过登录上网，因为wifi虽然不可以上网，但是却可以ping通你的服务器。In the coffee shop or airport, you can connect to free wifi, but you need to log in to verify. At this time, you can use this tool to bypass the login, because wifi can not surf the Internet, but you can ping your server.
|
||||||
|
* 在某些网络，tcp的传输很慢，但是如果用icmp协议，可能因为运营商的设置或是网络拓扑，速度会变快，实际测试在中国大陆连aws的服务器会有加速效果。In some networks, the transmission of tcp is very slow, but if the icmp protocol is used, the speed may be faster because of the operator's settings or the network topology. After testing, connecting the server of aws from mainland China has an accelerated effect.
|
||||||
- First prepare a server with a public IP, such as EC2 on AWS, assuming the domain name or public IP is www.yourserver.com
|
|
||||||
- Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_linux64.zip, then decompress and execute with **root** privileges
|
|
||||||
- “-key” parameter is **int** type, only supports numbers between 0-2147483647
|
|
||||||
|
|
||||||
|
# Sample
|
||||||
|
如把本机的:4455的UDP流量转发到www.yourserver.com:4455：For example, the UDP traffic of the machine: 4545 is forwarded to www.yourserver.com:4455:
|
||||||
|
* 在www.yourserver.com的服务器上用root权限运行。Run with root privileges on the server at www.yourserver.com
|
||||||
```
|
```
|
||||||
sudo wget (link of latest release)
|
|
||||||
sudo unzip pingtunnel_linux64.zip
|
|
||||||
sudo ./pingtunnel -type server
|
sudo ./pingtunnel -type server
|
||||||
```
|
```
|
||||||
|
* 在你本地电脑上用管理员权限运行。Run with administrator privileges on your local computer
|
||||||
- (Optional) Disable system default ping
|
|
||||||
|
|
||||||
```
|
|
||||||
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
|
|
||||||
```
|
|
||||||
|
|
||||||
### Install the client
|
|
||||||
|
|
||||||
- Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_windows64.zip, and decompress it
|
|
||||||
- Then run with **administrator** privileges. The commands corresponding to different forwarding functions are as follows.
|
|
||||||
- If you see a log of ping pong, the connection is normal
|
|
||||||
- “-key” parameter is **int** type, only supports numbers between 0-2147483647
|
|
||||||
|
|
||||||
|
|
||||||
#### Forward sock5
|
|
||||||
|
|
||||||
```
|
|
||||||
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -sock5 1
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Forward tcp
|
|
||||||
|
|
||||||
```
|
|
||||||
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Forward udp
|
|
||||||
|
|
||||||
```
|
```
|
||||||
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
|
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
|
||||||
```
|
```
|
||||||
|
* 如果看到客户端不停的ping、pong日志输出，说明工作正常。If you see the client ping, pong log output, it means normal work
|
||||||
|
```
|
||||||
|
ping www.xx.com 2018-12-23 13:05:50.5724495 +0800 CST m=+3.023909301 8 0 1997 2
|
||||||
|
pong from xx.xx.xx.xx 210.8078ms
|
||||||
|
```
|
||||||
|
* 如果想转发tcp流量，只需要在客户端加上-tcp的参数。If you want to forward tcp traffic, you only need to add the -tcp parameter to the client.
|
||||||
|
```
|
||||||
|
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
|
||||||
|
```
|
||||||
|
* 如果想转发sock5流量，只需要在客户端加上-sock5的参数。If you want to forward sock5 traffic, you only need to add the -sock5 parameter to the client.
|
||||||
|
```
|
||||||
|
pingtunnel.exe -type client -l :4455 -s www.yourserver.com -sock5 1
|
||||||
|
```
|
||||||
|
* 大功告成，然后你就可以开始和本机的:4455端口通信，数据都被自动转发到远端，如同连接到www.yourserver.com:4455一样。 Then you can start communicating with the local: 4455 port, the data is automatically forwarded to the remote, as you connect to www.yourserver.com:4455.

# Usage
|
||||||
|
通过伪造ping，把tcp/udp/sock5流量通过远程服务器转发到目的服务器上。用于突破某些运营商封锁TCP/UDP流量。
|
||||||
|
By forging ping, the tcp/udp/sock5 traffic is forwarded to the destination server through the remote server. Used to break certain operators to block TCP/UDP traffic.
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
|
||||||
|
// server

|
pingtunnel -type client -l LOCAL_IP:4455 -s SERVER_IP -t SERVER_IP:4455
|
||||||
|
|
||||||
|
// client, Forward tcp
|
||||||
|
pingtunnel -type client -l LOCAL_IP:4455 -s SERVER_IP -t SERVER_IP:4455 -tcp 1
|
||||||
|
|
||||||
|
// client, Forward sock5, implicitly open tcp, so no target server is needed

Deploy with docker-compose
|
|
||||||
===========================
|
|
||||||
**First** edit `.env` file in this directory to your appropriate value.
|
|
||||||
|
|
||||||
**Then** run stack with these commands:
|
|
||||||
|
|
||||||
- in the server
|
|
||||||
```
|
|
||||||
docker-compose -f server.yml up -d
|
|
||||||
```
|
|
||||||
- in client machine
|
|
||||||
```
|
|
||||||
docker-compose -f client.yml up -d
|
|
||||||
```
|
|
||||||
|
|
||||||
**Now** use socks5 proxy at port `1080` of your client machine
