## Options
```
--addr, -a IP address to listen at
--port, -p "8080" Port number to listen at
--permit-write, -w Permit write from client (BE CAREFUL)
--addr, -a IP address to listen [$GOTTY_ADDR]
--port, -p "8080" Port number to listen [$GOTTY_PORT]
--permit-write, -w Permit clients to write to the TTY (BE CAREFUL) [$GOTTY_PERMIT_WRITE]
```
By default, gotty doesn't allow clients to send any keystrokes or commands except terminal window resizing. When you want to permmit clients to write input to the PTY, add the `-w` option. However, accepting input from remote clients is dangerous for most commands. Make sure that only trusted clients can connect to your gotty server when activate this option. If you need interaction with the PTY, consider starting gotty with tmux or GNU Screen and run your main command on it.
