Readme
Hey, nice to meet you, you found this charming tool. Here the Cactus Tunnel is a TCP tunnel tool over WebSocket and Browser. It can help you open a TCP tunnel to another side of the world through the browser in an extremely restricted environment, just like a cactus under the scorching sun to absorb nutrients in the endless desert. If you are a thirsty and honey geek and focus on finding new hydration, don't miss it.

Usage: cactus-tunnel client [options] <server> <target>
runs cactus-tunnel in client mode
Arguments:
server tunnel server url, empty is bridge mode, e.g.
ws://your-tunnel-server:7800

--help display help for command
Request External API Services
Start a tunnel client:
cactus-tunnel client -b ws://<your-tunnel-server>:7800 api.ipify.com:80
This command will start a server at address localhost:7700
in bridge mode,
and open the tunnel bridge on the web browser.
curl http://localhost:7700/\?format\=json
When you connect to the port 7700
, it will auto connect to the specified
tunnel server <your-tunnel-server>:7800
and connect to target host
api.ipify:80
, you will get your server ip address through the IP API lookup service,
the response content is similar as below:
$ curl http://localhost:7700/\?format\=json
{"ip":"201.xxx.xxx.138"}%
SSH SOCKS5 Proxy
Start a tunnel client:
cactus-tunnel client -b ws://<your-tunnel-server>:7800 <your-ssh-server>:22
This command will start a server at address localhost:7700
in bridge mode,
and open the tunnel bridge on the web browser.
ssh -p 7700 -D 3128 -C -N <your-username>@localhost
-D 3128
: open a SOCKS5 proxy on local port3128
-C
: compress data in the tunnel, save bandwidth-N
: do not execute remote commands, useful for just forwarding ports
When you connect to the port 7700
, it will auto connect to the specified
tunnel server localhost:7800
and connect to target host <your-ssh-server>:22
Now you have an SSH tunnel between your computer and the remote host, in
this example <your-ssh-server>:22
.
Import the package
A simple example:
import cactusTunnel from "cactus-tunnel";
const options = {
port: 1234,
hostname: localhost,
};
const server = new cactusTunnel.Server({
listen: {
port: options.port,
hostname: options.hostname,
},
logger: {
silent: options.verbose ? false : true,
},
});
console.info(`server listening at: http://${options.hostname}:${options.port}`);
Development
To set up your environment to develop this tool, run npm install
.
Your environment is setup just like a normal node project! To test your
project, run npm start:cli help
. This shows help instructions of CLI
tool. You can edit the source code under src
, bin
, test
, etc. like
normal to test NodeJS project. As you make modifications to the source
code and configuration files, you need to rerun the command and you
should see the changes, just like normal.
