014.01.32.1. Can you explain the step-by-step process involved in connecting a Linux machine to the internet, considering the roles of the network hardware, kernel drivers, and the Linux kernel’s network interfaces?
Connect the network hardware & ensure the kernel has a driver for it. If the driver is present, ip address show includes an entry for the device, even if it hasn't been configured.
Perform any additional physical layer setup such as choosing a network name or password.
Assign IP addresses & subnets to the kernel network interface so that the kernel's device drivers(physical layer) & internet subsystem can talk to each other.
Add any additional routes, including the default gateway.
Here is a step-by-step process for connecting a Linux machine to the internet, considering the roles of network hardware, kernel drivers, and Linux kernel's network interfaces:
Connect Network Hardware and Ensure Driver Availability:
Connect the network hardware to the machine.
Ensure that the Linux kernel has a driver for the connected hardware. The presence of the driver can be checked using the ip address show command. An entry for the device should appear, even if it hasn't been configured yet.
Perform Additional Physical Layer Setup:
Set up any additional physical layer configurations, such as choosing a network name or password.
Assign IP Addresses and Subnets:
Assign IP addresses and subnets to the Linux kernel's network interface. This step establishes communication between the kernel's device drivers (physical layer) and the internet subsystem.
Configure Routes, Including Default Gateway:
Add any necessary routes, including setting the default gateway. This step ensures proper routing of network traffic.
Following these steps ensures that the Linux machine is correctly connected to the internet.
