Driver Lab

This lab turns your laptop into a local web server, allowing your Android phone to access files from it using a web browser.

1. Connect Both Devices to the Same Wi-Fi

• Your laptop and Android phone must be on the same Wi-Fi network (e.g., your home Wi-Fi).
• If you don’t have Wi-Fi, you can create a mobile hotspot on your phone and connect your laptop to it.

2. Start a Python HTTP Server on Your Laptop

1. Open a terminal or command prompt on your laptop.
2. Navigate to the folder you want to share using:

Example: If you want to share your Downloads folder:

```bash
cd path/to/folder

```

```bash
cd ~/Downloads  # macOS/Linux
cd C:\Users\YourName\Downloads  # Windows

```

3. Run the following command to start a web server:

   python -m http.server 8000
   
   

   • This starts a web server on port 8000.
   • Your laptop is now serving files from this folder.

3. Find Your Laptop’s IP Address

Your phone needs to know your laptop’s IP address to connect.

On Windows

1. Open Command Prompt (Win + R, type cmd, press Enter).

2. Type:

   ipconfig
   
   

3. Look for the IPv4 Address under your Wi-Fi adapter.

   • Example: 192.168.1.100

On macOS/Linux

1. Open a terminal and type:

   ifconfig  # (or `ip a` on Linux)
   
   

2. Find the inet address under Wi-Fi (wlan0 or en0).

   • Example: 192.168.1.100

4. Access the Laptop from Your Phone

1. Open a web browser (Chrome, Firefox) on your Android phone.

2. In the address bar, type:

   <http://192.168.1.100:8000>
   
   

   (Replace 192.168.1.100 with your actual laptop’s IP.)

3. You should now see a list of files from your laptop’s shared folder!

   • Tap a file to download it. If it is an audio file, you can play it over the network.
   • Watch the terminal as you access content over the network. It gives you a status update for every resource you connect to. Now you can visualize what happens whenever you visit a website and access some content - e.g. a webpage with images, a video, or even python packages.

5. Stop the Server (When Done)

When you’re finished, stop the server by going back to your laptop’s terminal and pressing:

Ctrl + C

Now in the real world, the servers that store the information we access are configured to be online all the time.

Why Use This?

• No setup required—just Python and a shared Wi-Fi network.
• Quickly transfer files without USB cables.
• Works on any device with a web browser.

⚠️ Troubleshooting

If your phone can’t connect, try these:

1. Make sure your phone & laptop are on the same Wi-Fi.
2. Disable firewalls (Windows Defender, macOS Firewall) temporarily.
3. Try a different port (e.g., 8080 instead of 8000):

Then, access:

```bash
python -m http.server 8080

```

```
<http://192.168.1.100:8080>

```
