# TTY

## Step 1: Upgrade to TTY shell

In the **remote** shell, upgrade the shell to TTY:

```bash
python3 -c 'import pty; pty.spawn("/bin/bash")'
```

{% hint style="info" %}
**Step 1 is sufficient in most scenarios.** If you plan to use things like Vim or Nano for privesc, then you need to complete all steps.
{% endhint %}

## Step 2: Export terminal environmental variables

In your **local** shell, check the environmental variable `$TERM`:

```bash
$ echo $TERM
xterm-256color
```

In the **remote** shell, export the environmental variables `$TERM` and `$SHELL`:

```bash
export TERM=xterm-256color
export SHELL=/bin/bash
```

## Step 3: Set up terminal size

In your **local** shell, check terminal **rows** and **columns**:

```bash
$ stty size
36 145
```

In the **remote** shell, press **ctrl+z** to bring the current session to **background**:

```bash
^Z
[1]+  Stopped        nc -nlvp 443
```

Now you are brought back to the **local** shell. Bring the reverse shell to **foreground**:

```bash
$ stty raw -echo;fg
nc -nlvp 443
$                reset
```

Adjust the **terminal size**:

```bash
stty rows 36 columns 145
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ret2basic.gitbook.io/ctfnote/red-teaming/exploitation/tty.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
