This article focuses on the topic of making a permanent manual restart of the DHCP client for Jetson Orin AGX Developer Kit with JetPack 6.1 (Ubuntu 22.04 ARM64) that boots and has accessibility to the local network but has no Internet access due to a temporary failure in name resolution.
Introduction
The Jetson Orin AGX Developer Kit is a powerful and versatile platform for developers working on AI and machine learning applications. However, there may be instances where the DHCP client fails to obtain an IP address from the DHCP server, leading to a lack of Internet access. In such cases, a manual restart of the DHCP client can help. This article will guide you through the process of making a permanent manual restart of the DHCP client for Jetson Orin AGX Developer Kit.
Understanding DHCP Client
Dynamic Host Configuration Protocol (DHCP) is a network protocol used to dynamically assign IP addresses to devices on a network. When a device connects to a network, it sends a request to the DHCP server for an IP address. The DHCP server then assigns an available IP address to the device. This process is called DHCP lease.
DHCP Client on Jetson Orin AGX Developer Kit
On Jetson Orin AGX Developer Kit, the DHCP client is responsible for obtaining an IP address from the DHCP server. By default, the DHCP client starts automatically during the boot process. However, there may be instances where the DHCP client fails to obtain an IP address, leading to a lack of Internet access.
Making Permanent Manual Restart of DHCP Client
To make a permanent manual restart of the DHCP client on Jetson Orin AGX Developer Kit, you need to modify the network interface configuration file. The following steps will guide you through the process:
Step 1: Open the Network Interface Configuration File
Use a text editor to open the network interface configuration file. The file is located at /etc/network/interfaces.
sudo nano /etc/network/interfaces
Step 2: Add the Manual Restart Command
Add the following lines to the network interface configuration file to make a permanent manual restart of the DHCP client:
pre-up service isc-dhcp-client start
post-down service isc-dhcp-client stop
This will start and stop the DHCP client service before and after the network interface is brought up and down. This ensures that the DHCP client is restarted every time the network interface is enabled.
Step 3: Save and Close the Network Interface Configuration File
Save and close the network interface configuration file.
Ctrl+X, Y, Enter
Step 4: Restart the Network Interface
Restart the network interface to apply the changes.
sudo ifdown eth0 && sudo ifup eth0
This article has provided a detailed context on the topic of making a permanent manual restart of the DHCP client for Jetson Orin AGX Developer Kit. By following the steps outlined in this article, you can make a permanent manual restart of the DHCP client on Jetson Orin AGX Developer Kit, even if it fails to obtain an IP address from the DHCP server. This can help in resolving temporary failures in name resolution and restoring Internet access.
