# Connect to running sandbox

If you have a running sandbox, you can connect to it using the `Sandbox.connect()` method and then start controlling it with our SDK.

This is useful if you want to, for example, reuse the same sandbox instance for the same user after a short period of inactivity.

## 1. Get the sandbox ID
To connect to a running sandbox, you first need to retrieve its ID. You can do this by calling the `Sandbox.list()` method.

<CodeGroup>
```js
import { Sandbox } from "@e2b/code-interpreter"

// Get all running sandboxes
const runningSandboxes = await Sandbox.list() // $HighlightLine

if (runningSandboxes.length === 0) {
  throw new Error("No running sandboxes found")
}

// Get the ID of the sandbox you want to connect to
const sandboxId = runningSandboxes[0].sandboxId
```

```python
from e2b_code_interpreter import Sandbox

# Get all running sandboxes
running_sandboxes = Sandbox.list() # $HighlightLine

# Get the ID of the sandbox you want to connect to
if len(running_sandboxes) == 0:
  raise Exception("No running sandboxes found")

# Get the ID of the sandbox you want to connect to
sandbox_id = running_sandboxes[0].sandbox_id
```
</CodeGroup>

## 2. Connect to the sandbox

Now that you have the sandbox ID, you can connect to the sandbox using the `Sandbox.connect()` method.

<CodeGroup>
```js
import { Sandbox } from "@e2b/code-interpreter"

// Get all running sandboxes
const runningSandboxes = await Sandbox.list()

if (runningSandboxes.length === 0) {
  throw new Error("No running sandboxes found")
}

// Get the ID of the sandbox you want to connect to
const sandboxId = runningSandboxes[0].sandboxId

// Connect to the sandbox
const sandbox = await Sandbox.connect(sandboxId) // $HighlightLine
// Now you can use the sandbox as usual
// ...

```
```python
from e2b_code_interpreter import Sandbox

# Get all running sandboxes
running_sandboxes = Sandbox.list()

# Get the ID of the sandbox you want to connect to
if len(running_sandboxes) == 0:
  raise Exception("No running sandboxes found")

sandbox_id = running_sandboxes[0].sandbox_id

# Connect to the sandbox
sandbox = Sandbox.connect(sandbox_id) # $HighlightLine
# Now you can use the sandbox as usual
# ...

```
</CodeGroup>
