LIDAR Setup¶

To permanently set a static IP via GUI on Ubuntu Desktop (for your Hokuyo LiDAR setup), follow these steps:

✅ Step 1: Open Network Settings¶

1. Click the network icon in the top-right corner of the screen.
2. Choose "Wired Settings" (or "Settings → Network").
3. Click the gear ⚙️ icon next to your Ethernet connection (e.g., "Wired connection 1").

🌐 Step 2: Configure IPv4¶

1. Go to the "IPv4" tab.
2. Set Method to Manual.
3. Under Addresses, click Add and enter:

1. DNS: You can leave it empty or use:
   

   8.8.8.8, 1.1.1.1
   

💾 Step 3: Save and Apply¶

1. Click Apply.
2. Toggle the Ethernet connection off and on again.
3. Alternatively, restart your PC.

🧪 Step 4: Verify¶

Open a terminal and run:

ip a

Check that your Ethernet interface (e.g., enp3s0) now shows 192.168.3.100. Then test:

ping 192.168.3.11
nc -zv 192.168.3.11 10940

Now your static IP is set permanently and the machine is ready to communicate with the Hokuyo LiDAR. Let me know if you're using a specific Ubuntu version or a different desktop environment (e.g., KDE), and I can adjust the steps.
