⌨️ Local Sharing via HTTP or ssh

2 min read

Step 1: Connect the Ethernet Cable

  1. Use a standard Ethernet cable to connect the two machines.
  2. Modern computers don’t require a crossover cable, as most Ethernet ports auto-detect the connection type.

Step 2: Configure IP Addresses

You need to assign static IP addresses to both machines so they can communicate.

On Linux:

  1. Open a terminal.

  2. Use the following commands to set a static IP address:

    sudo ip addr add 192.168.1.1/24 dev eth0
sudo ip link set eth0 up

  • Replace eth0 with the correct interface name for your Ethernet adapter. You can find it using:

     ip link

On macOS:

  1. Go to System Preferences > Network.
  2. Select Ethernet in the left sidebar.
  3. Set Configure IPv4 to Manually.
  4. Enter the following:
    • IP Address: 192.168.1.2
    • Subnet Mask: 255.255.255.0
  5. Click Apply.

Using HTTP Server

Step 3: Use Python’s HTTP Server on Linux

Linux typically has Python pre-installed, which can be used to create a simple HTTP server.

Steps:

On the Linux Machine:

  • Open a terminal.
  • Navigate to the directory containing the files you want to share:

cd /path/to/share

  • Start a Python HTTP server:

python3 -m http.server 8000

  • This will make the directory accessible via HTTP on port 8000.

On the macOS Machine:

  • Open a web browser.
  • Enter the Linux machine’s IP address and port:

http://192.168.1.1:8000

  • Browse and download the files directly from the browser.

Using ssh-server

Step 3: Enable File Sharing

On Linux:

  1. Install and configure an SSH server to enable file transfers:

    sudo apt update
sudo apt install openssh-server
sudo systemctl start ssh

  2. Note the username of the Linux system (you’ll need it later).

On macOS:

No additional setup is required, as macOS has SSH and SCP (Secure Copy Protocol) built-in.

Step 4: Transfer Files

You can transfer files using the scp command.

From macOS to Linux:

  1. Open Terminal on the Mac.

  2. Run the command:

    scp /path/to/file username@192.168.1.1:/destination/path
    • Replace /path/to/file with the file you want to transfer.
    • Replace username with the Linux username.
    • Replace /destination/path with the target directory on the Linux machine.

From Linux to macOS:

  1. Run this command on the Linux machine:

    scp /path/to/file username@192.168.1.2:/destination/path
    • Replace username with your macOS username.

Step 5: Verify the Transfer

Check the destination folder on the target machine to ensure the files were transferred successfully.
