In this tutorial, How to check Disk is SSD or HDD on Linux . Solid-state drives (SSDs) are fast, silent, and less prone to failure than traditional hard disk drives (HDDs). HDD store information on a rotating disk known as a platter SSD use flash memory to store and persist data. Using lsblk command to check HDD or SSD lsblk -o name,rota | tail If you get a 1 then the disk is an HDD. A 0 (zero) on the column rota is SSD. The output terminal as below: Using the cat Command cat /sys/block/sda/queue/rotational If the result is 1, then the disk is an HDD. the output 0 ( zero) that disk is ssd. The output terminal as below:  

In this tutorial, we'll explore the process of changing MAC addresses in Linux. MAC addresses are used to uniquely identify devices on a network. Altering a MAC address can be useful for enhancing anonymity and security while connected to networks. Steps to Change MAC Address in Linux: 1. Open Terminal: Begin by opening the terminal and listing all network interfaces on your server using the following command: ip link show The output terminal below: 2. Select Interface: Identify the network interface for which you want to change the MAC address. For example, let's select the docker0 network interface. 3. Take Interface Down: Before changing the MAC address, take the selected network interface down using the following command: sudo ifconfig docker0 down 4. Change MAC Address: Now, you can change the MAC address to your desired value. For instance, to change from 02:42:c2:c6:e8:39 to 02:42:b2:b6:c8:40, use the following command: sudo ifconfig docker0 hw ether 02:42:b2:b6:c8:40
