Paid management exercises

Work with apt, aptitude, dpkg Exercise 1 What actions I get when performing apt update and apt upgrade. Explain in detail. The apt update command is the first fundamental step in the package update. It takes the following actions: -**Recovers Remote Metadata:**apt update communicates with online software repositories and recovers metadata related to available packages. These metadata include information on the latest versions of the packages, their dependencies and other essential information. -Update the Local Metadata Copy: Then apt reconstructs and updates the local copy of these metadata. This allows the system to quickly access information about the packages without having to download it repeatedly.

Transformation instance cloud

Creation of the LVM scheme We installed the LVM2 package Now we’ll create the partitions on the second disk: We create the group of volumes: We create the root and home volumes: The partitions must have the following format: -vdb2 etx4 FJCD-vg-home ext4 -FJCD-vg-raiz ext4 We would have to format the efi: So would our partition scheme: Copy the partition content Now let’s ride the partitions:

IPv6 Tunnels

Introduction In this detailed post, we explore the process of configuring IPv6 to IPv4 tunnels and vice versa in Linux and Cisco environments. As the migration to IPv6 gains importance, the ability to establish communication between IPv4 and IPv6 networks becomes essential. We will cover the basics of tunnel configuration, including the most common types of tunnels, such as 6to4 and Teredo. Additionally, we will provide step-by-step instructions for configuration on both Linux systems and Cisco devices.

NAT Cisco and Linux Configuration

In this article, we will explore the configuration of SNAT (Source Network Address Translation) and DNAT (Destination Network Address Translation) in scenarios with public addresses, using routers in Linux environments and Cisco devices. Scenario with debian machines Preparation of the environment Installation of packages Once the machines are placed we must download Apache for the web servers, to do this we will connect both servers to a switch and this to the NAT cloud for Internet access.

Packaging and compressors in Linux

Packers and compressors are key elements in the management of files and data in the computer field. The packers allow to group several files in a single container, facilitating their handling and transport. On the other hand, compressors apply techniques to reduce file size, contributing to storage space savings and expediting data transfer. These tools play a crucial role in resource optimization and operational efficiency by more effectively organizing, distributing and supporting information.

Share directories with NFS in debian

The NFS (Network File System) technology has been a key part of file sharing in network environments. Developed by Sun Microsystems, NFS allows Unix and Linux operating systems to share file resources transparently, providing access to remote files and directories as if they were stored locally. 1.Installation and NFS configuration We installed the nfs-kernel-server package. We will create the directory we are going to share and change the owners and permissions of it:

Storage Spaces on Windows Server

Storage Spaces is a software-defined storage feature in the Windows Server operating system that allows system administrators to combine several physical disks in a single logical storage space called “storage pool.” This storage pool can be used to create virtual storage spaces called “storage spaces” that offer various redundancy functions and advanced storage management capabilities. Storage groups The following Windows PowerShell cmdlets perform the same function as the previous procedure. Write each cmdlet in a single line, although here you can appear with line jumps between several lines here due to format restrictions.

Underworld evolution

The world of UNDERWORLD has evolved greatly in recent months, so you must perform network management tasks to face the new situation. On one hand, the Internet has been discovered in the Underworld, allowing each of the sub-worlds (remember: vampires, werewolves, lycanthropes, and humans) to connect to a router that, in turn, connects them to one of the two large routers that form Underworld’s Internet, called Marcus (for humans and vampires) and Alexander (for werewolves and lycanthropes). Marcus and Alexander are connected to each other.
