Introduction

In this post, I configured the communication settings for the Jetson Xavier, following the OS setup I performed previously.

Since I wanted to use it as a home server, I’ve made it accessible even from external networks. The tool I used this time, Tailscale, is incredibly convenient, and I have also introduced it to my Windows environment.

Connecting to the Internet

As was the case with the Jetson Nano, the Jetson Xavier does not have built-in components for wireless connectivity.

▼With the Jetson Nano, I connected using a USB Wi-Fi dongle.

While it does have an Ethernet port, my wireless router was in a different room, making it impossible to plug in a LAN cable directly. Fortunately, I had a Wi-Fi extender, so I connected the Xavier to it via Ethernet.

▼I am using this spare Wi-Fi extender. It also has an Ethernet port.

I configured the settings to link the wireless router and the extender. The access address, username, and password for the extender were written on the device itself.

▼I connected to the extender's access point and logged in.

▼I configured the connection destination.

After this, I connected the Jetson Xavier to the extender via a cable and was able to log in from another PC via SSH.

Installing Node-RED

I installed Node-RED, a tool I use frequently. It is a flow-based programming tool that makes implementing communication-related tasks particularly easy.

▼The Raspberry Pi script on the following page can also be used on Ubuntu.

https://nodered.jp/docs/getting-started/raspberrypi

I connected to the Jetson Xavier via SSH from another PC and executed the following commands:

sudo apt update
sudo apt upgrade
sudo apt install curl
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

▼I encountered an error stating that "curl" was missing, so I installed it first.

Most of the setup options displayed in the terminal were left as default, but since I wanted to allow access across different networks, I configured the security settings.

▼Enabling "User Security" requires a username and password upon access.

▼After running "node-red" in the terminal and accessing http://:1880, I was prompted for credentials.

I successfully accessed the Node-RED editor screen.

Trying Out Tailscale

I was now able to perform SSH connections and log in to Node-RED within the local network. Next, I looked for a way to access the home Jetson Xavier from anywhere across the internet.

▼I have used Ngrok before, but in the free tier, the data limit is 1GB per month, which I exhausted quickly.

When I asked ChatGPT for advice, it introduced me to something called Tailscale.

▼Information on how Tailscale works can be found here:

https://tailscale.com/blog/how-tailscale-works

It seems to be a mechanism for easily implementing a VPN. I’m not an expert on VPNs, but I decided to give it a try.

▼Installation instructions for various environments are available here:

This time, I had ChatGPT provide the commands. I was able to install it using "snap".

sudo snap install tailscale
sudo tailscale up

▼The installation went smoothly.

▼A login URL was displayed.

When you run "sudo tailscale up," a URL for logging in is displayed. After accessing that URL and logging in, the setup was completed without any issues.

▼Even with other devices set up, you can check the addresses in the browser management console like this. I was also able to establish an SSH connection using this address.

There is also a mechanism called "Funnel," which allows you to expose ports to the public internet, similar to Ngrok.

▼Funnel is explained on this page. It is currently a beta feature.

▼I enabled Funnel in the browser management console.

I wanted to access Node-RED (running on port 1880) from the outside, so I used Funnel for port 1880.

sudo tailscale funnel 1880

▼It was necessary to execute this with "sudo".

A URL for connecting via HTTPS was issued. Upon accessing that URL, the Node-RED login screen appeared once again.

Since the Funnel becomes inactive when the SSH terminal is closed, I used the Node-RED "exec" node to execute the Funnel command for port 1880 at startup.

▼Since it needs to run with "sudo," you must pass the password when executing the command.

▼I created the flow as follows:

Now, the Funnel is automatically executed upon startup.

▼I combined this with an "email" node to notify me of the issued URL.

Note that the URL issued by Funnel can also be confirmed in the Tailscale management console.

Finally

Using Tailscale, I can now easily access my device even from external networks. It worked perfectly on my Windows PC as well, so I plan to summarize that in another article.

▼Since SSH involves command-line operations, I use Google Chrome Remote Desktop for GUI-based operations.
