Basic IPv6 Scenario

Throughout this guide, we will explore the configuration of a basic scenario using IPv6 networks on both Linux and Cisco devices. We will also address the configuration of an Apache server using IPv6 capabilities. Linux IPV6 Self-Configuration Connect two Linux machines to the same switch and check that they have IPv6 connectivity using the local link address. We’ll check the IPV6 that the different pcs have. PC1 has - > fe80::ef7:42ff:fe92:0/64

Active Directory in Ubuntu

In this post, we will explore how to set up an Active Directory environment on an Ubuntu server using tools such as Kerberos and Samba. Active Directory is an integral Microsoft solution for identity management and access control in business networks. Through this guide, we will learn step by step how to implement a Ubuntu server as a domain controller, establish Kerberos-based authentication and configure directory services by using Samba.

Centralized collection of system log, using journald

Step 1 Install system -journal-remote In our environment, the first step will be to install the system-journal- remote package, which will allow us to access these machines remotely. To carry out the installation on our stage machines, we will use the apt package manager in Odin, which runs Debian 12. We will also install the same package in Thor and Loki, which are containers housed within Odin. As for Hela, a Rocky operating system, it will require the use of dnf for installation.

Disposal of systemd

Systemd and System V (SysV) are two start-up systems used in Linux distributions to manage system and service boot. System V (SysV) is a traditional start-up system that uses shell scripts stored at different running levels (runlevels) to start and stop services sequentially. It was widely used in many Unix and Linux distributions for decades. On the other hand, Systemd is a more modern and advanced start-up system that replaces SysV. Incorporated to improve system start speed and efficiency, systemd uses a unit-based approach and depends on paralleling to start services simultaneously. It also includes additional features such as service management, sockets, timers, and dependencies, making it a more robust and flexible option compared to SysV.

Install and configure samba in Debian

Samba is a free and open source implementation of the Server Message Block (SMB) protocol, which is used to share files and printers on computer networks. The SMB protocol is a network protocol that allows Windows operating systems to communicate with other network devices, such as file servers, printers and other shared resources. Samba facilitates interoperability between Windows systems and Unix / Linux-based operating systems by allowing Unix systems to share files and resources with Windows systems using the SMB / CIFS protocol. This means that a Samba server can act as a file server for Windows customers, allowing them to access and share files as if they were in a Windows environment.

Linux task programming commands

The efficient management of programmed tasks is essential for system managers as it facilitates the automatic execution of routine processes. In this context, having a solid set of Linux commands to program and control tasks becomes a fundamental tool. Sleep command The sleep command stops running in the terminal for a specified time interval before returning to the command line. You can indicate the time in seconds, minutes, hours or days. This command is found in the choreutils package.

SELinux activation configuration

Enable SELinux on a Rocky-based server and make sure that the samba and nfs services work properly with a strict and secure SELinux configuration. Conducts the corresponding access tests. The stage consists of two machines, our server is based on Rocky 9 and our client is a Debian 12. On our server we will have SELinux enabled in enforcing mode. [rocky@rocky-javiercruces ~]$ sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Memory protection checking: actual (secure) Max kernel policy version: 33 We will start by updating the packages needed to configure samba and nfs:

ARP Protocol

The Address Resolution Protocol (ARP) is fundamental in computer networks to map IP addresses to physical link layer addresses (MAC). Its main function is to find the MAC address associated with a specific IP address on a local network. When one device needs to communicate with another on the same network, it uses ARP to determine the MAC address of the destination before sending data. Do you think the ARP question is a message of dissemination? Make a Wireshark capture of an ARP request and analyze it to justify your response. Yes, it is a message of dissemination as in the header we can see that the destination has a broadcast address. This address is the one that has all its bits at 1 which in the mac addresses is translated into FF:FF:FF:FF:FF:FF.

DNS server configuration in Debian

Dnsmasq The dnsmasq package allows you to start a DNS server in a very simple way. Simply by installing and starting the dnsmasq service, without any additional configuration, our PC will become a DNS cache server and will also solve the names we have configured in the / etc / hosts file of our server. The resolution will work both directly and inversely, that is, it will solve the IP given a PC name and the PC name given the IP.
