Setup and Configuration

Configuration

Upon booting the system will enter the dentOS environment, after which users can start configuring the system.

We can print basic information about the operating system using the uname tool. uname -a will give information about all options, such as kernel name and version, hardware platform, processor archivesture, information about the operating system, etc.

ONIE:/ # uname -a
Linux (none) 4.9.95-gf9ad16f #1 SMP PREEMPT Fri Jan 8 15:58:30 CST 2021 aarch64

System information

Password for the root user can be set with the passwd command:

~ $ passwd

We can view the operating system information by printing the /etc/os-release file:

ONIE:/ # cat /etc/os-release
NAME="onie"
VERSION="2020.11-V01"
ID=linux

Locale configuration

Locale is a set of environment variables that define country, language and character encoding settings for various applications and the shell session on the Linux system. locale utility can be used to view information about the curretly installed locale.

Time configuration

System time is used in all Linux systems to keep track of time. It can se set by an onboard hardware clocl or by an external time server. s Systemd init provides the timedatectl utility to manage time zones. We can list all available timezones with:

~ $ timedatectl list-timezones

To change the time zone, e.g. for UK:

~ $ timedatectl set-timezone Europe/London

Setting up network connection

Upon booting the device we can set up a working network connecion. The are multiple ways of doing this, out of which the simplest one being, configuring the management 1 port intereface using dhclient:

ONIE:/ # dhclient ma1

The device should now have a working network connection. We can verify this with the ping command:

ONIE:/ # ping 8.8.8.8
