title	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.

```js JavaScript & TypeScript import { Sandbox } from '@e2b/code-interpreter'

const sbx = await Sandbox.create()

// Get all running sandboxes const paginator = await Sandbox.list({ query: { state: ['running'] }, })

const runningSandboxes = await paginator.nextItems() 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 Python
from e2b_code_interpreter import Sandbox

sbx = Sandbox.create()

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

# Get the ID of the sandbox you want to connect to
running_sandboxes = paginator.next_items()
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

2. Connect to the sandbox

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

```js JavaScript & TypeScript highlight={3} import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.connect(sandboxId)

// Now you can use the sandbox as usual // ... const result = await sandbox.commands.run("whoami") console.log(Running in sandbox ${sandbox.sandboxId} as "${result.stdout.trim()}")

```python Python highlight={3}
from e2b_code_interpreter import Sandbox

sandbox = Sandbox.connect(sandbox_id)

# Now you can use the sandbox as usual
# ...
r = sandbox.commands.run("whoami")
print(f"Running in sandbox {sandbox.sandbox_id} as \"{r.stdout.strip()}\"")
