I’m having trouble locating the IP address of my Raspberry Pi running Ubuntu 20.04 and I’m unable to establish an SSH connection. Can anyone provide guidance on how to resolve this issue?

I could really use some help here because I’m kind of stuck with my Raspberry Pi. So, I’ve got this little beauty running Ubuntu 20.04, and I’ve been trying to get it set up for some home automation projects. The problem is, I can’t seem to locate its IP address, which means I can’t connect to it via SSH. I feel like I’ve tried everything, and it’s super frustrating!

I thought it would be as simple as just hooking it up, but I’m not seeing it pop up on my router’s device list. I tried using nmap, it didn’t help much. I’m connected to the same Wi-Fi network, so I figured that would be enough. I even checked if the Pi is properly powered up and, well, the LEDs seem all good. That green LED is flashing, so I assume it’s doing something, right?

Also, I heard that you can connect a keyboard and monitor directly to the Pi to check the IP, but I don’t have an extra monitor lying around, and my keyboard is acting up just when I want to use it. I don’t really want to spend money on peripherals I only need for this one time. Is there another way I can find the IP?

I read somewhere about using Avahi or Bonjour—whatever that is—but I’m not sure how to get that going. Should I enable something on the Pi beforehand?

If anyone has been in a similar situation or has any tips on how to tackle this, I’d be really grateful. It’s just annoying because I was so excited to start my project and now I feel like I’m hitting a brick wall. Any advice on alternative methods to find the IP address or getting SSH access would be a lifesaver! Thanks!

    1. Raspberry Pi IP Address Help

      Raspberry Pi Struggles

      Sounds like you’re in a bit of a pickle! Finding the IP address of your Raspberry Pi can be tricky sometimes, especially if it’s being a bit shy on the network. Here are some ideas that might help you out!

      Check Your Router Again

      Even if you didn’t see it before, it’s worth checking your router’s device list again. Sometimes, waiting a bit after plugging it in helps. Look for any devices that are named something like “raspberrypi” or have a manufacturer like “Broadcom” or “Raspberry”.

      Use a Smartphone

      If you have a smartphone, you can try downloading a network scanner app from your app store (like Fing). These apps can help you scan your local network and find the Raspberry Pi’s IP address without needing any extra software on your laptop!

      Check for Avahi/Bonjour

      You mentioned Avahi or Bonjour, which are for local devices to announce themselves over the network! If it’s installed on your Pi, you can usually access it via its hostname. Just type ping raspberrypi.local into your terminal (replace “raspberrypi” with the hostname if you’ve changed it). If it responds, you might get its IP that way!

      Try Ethernet Connection

      If you have an Ethernet cable, try connecting your Raspberry Pi directly to your router. This often helps because it can sometimes get an IP address more reliably this way.

      Online Community

      Since you’re trying to dive into home automation, there’s a great community out there for Raspberry Pi enthusiasts! Check out the Raspberry Pi forums or Reddit’s r/raspberry_pi. You might find someone who’s been through the same issue!

      Don’t worry too much; it can be frustrating at first, but once you get past this hurdle, you’ll be well on your way to your home automation project! Good luck!



    2. To find the IP address of your Raspberry Pi running Ubuntu 20.04, you can utilize the Avahi service, which implements the Bonjour protocol for zero-configuration networking. First, ensure that the Avahi daemon is installed on your Raspberry Pi. You can do this by accessing the Pi via a temporary connection, such as an Ethernet cable directly to your router, or by any means that allow you to log in to the system. Once you have access, run the following commands in the terminal:
      sudo apt update and sudo apt install avahi-daemon avahi-utils. After installation, start the service with sudo systemctl start avahi-daemon. This will enable your Raspberry Pi to broadcast its presence on the network, allowing you to access it via its hostname (usually raspberrypi.local) from another device on the same network without needing to know the actual IP address.

      If you are still struggling to locate the Pi, consider using a mobile app like Fing or Angry IP Scanner that can scan your local network for connected devices. These tools often provide easier interfaces for discovering devices than manual command-line tools. Additionally, if you have access to a router management interface, look for a feature that lists connected devices. It often displays the IP addresses in use. If you do get the Pi online via Ethernet, you can later set a static IP address in your router settings or configure it on the Pi to avoid having this issue in the future. Patience and persistence will pay off, and you’ll soon be on your way to enjoying your home automation projects!
