Linux

It is a Unix / Linux file sharing service developed by Sun Microsystems and is a stable technology that enables file sharing between Linux systems.

We need to get into configuration and use it right away. We will work with the Server and Client model in the environment. In other words, we have to configure both the server-side, there are settings that we should not make for the client to use. We will create these applications on the virtual machine.

By following the steps below, we’ll see how you can upload your KVM virtuals and return them from the backup again.

1. Backup Import

First, let’s list our machines and see that they are operational. To do this, we use the following command.

> virsh list –all

Then we close the VM we will install.

> virsh shutdown Ubuntu18

Then let’s list the machines again and see that they are turned off.

KVM Kernel-based virtual machine is a virtualization application developed for the Linux kernel that converts it to a higher system.

Before installation, login to our server to see if it supports CPU, let’s check the CPU information with the help of the following commands.

The output of this command means  “CPU(s):” 0 does not support if it is 0, and if it is more than 1 or 1, it means it supports.

If DNS Recursion is turned on, you are exposed to the “DNS Amplification Attack”  attacks. This attack is also known as a DNS-powered DDOS attack. For this reason, DNS Recursion should be turned off and we will see how to do this. Assuming you are more or less familiar with the consequences of a DDOS attack, what is DNS Amplification Attack? I leave here a beautiful video explaining the situation without drowning in too much detail.

IBM servers can be remotely controlled by hardware. In cases where the server needs to be physically restarted, shut down, and turned on, ipmitool commands can be used instead of the Web Console. You can even switch from console to operating system level and make transactions. We will do this by using the IP that we assigned to the server with IPMITOOL IP SET. You must install the  ipmitool package on the user side.
