You Should Know:

Linux-based automation hardware is increasingly becoming a cornerstone in industrial automation due to its flexibility, open-source nature, and robust performance. Below are some practical commands and steps to get started with Linux-based automation:

1. Installing Linux on Automation Hardware:

Download the latest Ubuntu Server ISO from the official Ubuntu website.

Use `dd` command to create a bootable USB:

sudo dd if=ubuntu-22.04.1-live-server-amd64.iso of=/dev/sdX bs=4M status=progress

Boot the automation hardware from the USB and follow the installation prompts.

2. Setting Up SSH for Remote Access:

Install OpenSSH server:

sudo apt update
sudo apt install openssh-server

Enable and start the SSH service:

sudo systemctl enable ssh
sudo systemctl start ssh

Connect remotely using:
```
ssh username@ip_address
```

3. Automating Tasks with Cron Jobs:

Edit the crontab file:
```
crontab -e
```
Add a cron job to run a script every day at 2 AM:
```
0 2 * * * /path/to/script.sh
```

4. Monitoring System Performance:

Use `htop` for real-time system monitoring:
```
sudo apt install htop
htop
```
Check disk usage:
```
df -h
```

5. Networking Configuration:

Configure a static IP address:
```
sudo nano /etc/netplan/01-netcfg.yaml
```

Example configuration:

network:
version: 2
ethernets:
eth0:
dhcp4: no
addresses: [192.168.1.100/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8, 8.8.4.4]

Apply the configuration:
```
sudo netplan apply
```

6. Security Hardening:

Update the system regularly:
```
sudo apt update && sudo apt upgrade -y
```

Configure a firewall using ufw:

sudo apt install ufw
sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 80/tcp
