# Create TCP Tunnels with Pinggy

Create a tunnel using a single command.


```bash
# SSH - no install, works anywhere the ssh client is available
ssh -p 443 -R0:localhost:8000 tcp@free.pinggy.io
```

```bash
# Pinggy CLI - install with: npm install -g pinggy (or download the binary)
./pinggy -p 443 -R0:localhost:8000 tcp@free.pinggy.io
```


This command present user with a URL and a TCP port. Port allocation changes per connection. However, one can reserve a port on <https://dashboard.pinggy.io>
