By default, GoTTY doesn't allow clients to send any keystrokes or commands except terminal window resizing. When you want to permit clients to write input to the PTY, add the `-w` option. However, accepting input from remote clients is dangerous for most commands. When you need interaction with the PTY for some reasons, consider starting GoTTY with tmux or GNU Screen and run your main command on it (see "Sharing with Multiple Clients" section for detail).

To restrict client access, you can use the `-c` option to enable the basic authentication. With option, clients need to input the specified username and passwords to connect to the GoTTY server. The `-r` option is a little bit casualer way to restrict access. With this option, GoTTY generates a random URL so that only people who know the URL can get access to the server.

All traffic between servers and clients are NOT encrypted by default. When you send secret information through GoTTY, we strongly recommend you use the `-t` option which enables TLS/SSL on the session. By default, GoTTY loads the crt and key files placed at `~/.gotty.crt` and `~/.gotty.key`. You can overwrite these file paths with the `--tls-crt` and `--tls-key` options. When you need to generate a self-signed certification file, you can use the `openssl` command. All traffic between the server and clients are NOT encrypted by default.

## Sharing with Multiple Clients ## Sharing with Multiple Clients
GoTTY starts a new process when a new client connects to the server. This means users cannot share a single terminal with others by default. However, you can use terminal multiplexers for sharing a single process with multiple clients. GoTTY starts a new process with the given command when a new client connects to the server. This means users cannot share a single terminal with others by default. However, you can use terminal multiplexers for sharing a single process with multiple clients.
For example, you can start a new tmux session named `gotty` with `top` command by the command below. For example, you can start a new tmux session named `gotty` with `top` command by the command below.

## Architecture ## Architecture
GoTTY uses [hterm](https://groups.google.com/a/chromium.org/forum/#!forum/chromium-hterm) to run a JavaScript based terminal on web browsers. GoTTY itself provides a websocket server that simply relays output from the PTY to clients and receives input from clients and forwards to the PTY. This hterm + websocket idea is highly inspired by [Wetty](https://github.com/krishnasrinivas/wetty).
