Check Host Connection Status in a VMWare Cluster

Check Host Connection Status in a VMWare Cluster

Here is a script on VMware via Powershell. As long as you have installed the PowerCLI module, you can run this via the standard Powershell. I have taken the script and created a PS1 file to run through the list and email it to you. This will help in the cases whereby you have multiple hosts and needs to be aware of the connection status. Now all your resources may not have access to VCenter or…

Setting up Always On  SQL Clustering Group, with Microsoft Server 2016 and VMWare

Setting up clusters in Windows Server 2016 has become so easy. However; When integrating it with other environments, like VMWare, and AO SQL Clustering. It can get quite Tricky. First we want to setup our environment in VSphere. Next we will setup Windows Server 2016 with Failover Clustering. Then we’ll make sure to make some adjustments to DNS. Finally, We will setup AlwaysOn SQL Clustering. 

Please make sure you have .NET Framework 3.5.1 or greater on the servers. Then We will need to create 2 VMs with 3 drives each. Then we will need to make sure that the drives are online, and available from other locations. However one main aspect that I had overlooked was that the Virtual Disks have to be created Eager Zero Thick not Lazy Zero Thick. I made the heinous mistake of using Lazy Zero Thick, and then could not understand why I was having so many problems. 

Note: When creating virtual disks with Eager Zero Thick, it does take longer than using the faster Lazy Zero Thick option. Eager Zero Thick Disks allocates the space for the virtual disk, then zeros it all out unlike the Lazy Zero Thick which only allocates the space. 

You also generally wouldn’t use Eager Zero Thick except for Microsoft clustering and Oracle programs. Once the disks are created we are reading to install Windows Server 2016.

Install either Datacenter edition or Standard edition. For this example we’ll use the standard edition. Install all the Microsoft Windows feature updates and verify that you have already allocated all the resources needed. Check that the additional Virtual Disks are available, and make sure you install the Failover Cluster feature. You may want to reboot after the feature is installed, if you have not done so. Once you installed the feature go to the Failover Cluster Manager and prepare to create the cluster. If this is a two node cluster be sure to add a Witness Server or Desktop. Once this is created and validated, go to your computer manager and verify that the virtual disks are online and initialized. Next, you will want to configure the cluster quorum settings. I created a separate server for this quorum and configured a File share witness. 

Now, make sure you can access these from another computer on the secured network. You will have to setup a Host A record round robin DNS situation, where you give a specified name the 2 failover cluster nodes IP adresses in the Host address. Example: if the nodes had up address of 192.168.1.43 and 192.168.1.44. Then the two Host records you would need to create are AOSqlServer -> 192.168.1.43 and AOSqlServer -> 192.169.1.44

Finally, We will enable AlwaysOn Availability Groups on SQL Server 2016. 

After Installing SQL Server 2012 or 2014 Enterprise edition on all the replicas. Please install it on as a stand-alone instance, and then we will configure SQL Server. Once you expand SQL Server Network Configuration node, and click on Protocols for MSSQLServer, you will see the TCP/IP dialog box on the right panel. Right click on the TCP/IP entry and select Enable. 

In SQL Server Configuration Manager, right click on SQL Server Services to open the Properties dialog box. Navigate to the AlwaysOn High Availability tab to select the “Enable AlwaysOn Availability Groups.

Now we must configure the login accounts and the replicas that will need read write privileges. 

First verify that your SQL Service Account is there and is a domain account, not a local machine account. Now login through SQL Management Studio (SSMS). Add you SQL Service account to the Administrators group on each replica (via computer management). Then allow connect permissions to the SQL Service account through SSMS: Right click on the SQL Service login to open the Properties dialog box. On each replica navigate to the Securables page and make sure Connect SQL Grant box is checked and allow remote connections. You can do this by using SSMS in the instance properties or by using sp_configure.

EXEC sp_configure ‘remote access’, 1;

GO

RECONFIGURE;

GO

Now we will create the file share through the Server Manager that the SQL Service account, and the replicas can access. The File is for the initial backup/restore process that happens to the databases when you join the AlwaysOn group during setup.

Last thing is to install the AlwaysOn Availability group. Once you’s ensured that full backups have been created, and all databases are in Full recovery mode, you will have to remove these databases from the tlog backup maintenece during the installation of Always on (you can always add them back). It could cause errors with both tlogs backing up while AlwaysOn is being created.

On you primary, open SSMS and expand the AlwaysOn High Availablity folder. Right click on the Availability Groups and select New Availability Group Wizard.

Select only the databases you want to include in the AlwaysOn group.

Next to the databases you will see the status with a blue link. If you see "Meets Prerequisites” it will signify that these databases are included in your group. If it does not say "Meets Prerequisites”, then click on the link to see more details on what needs to be corrected.

Now, you will specify and Add the Replicas. You will need to specify if you want Automatic or Manual Failover, Synchronous or Asynchronous Data Replication, and the type of Connections you are allowing to the end users.

Be sure to view the troubleshooting page if you have any issues:

http://blogs.msdn.com/b/alwaysonpro/archive/2013/12/09/trouble-shoot-error.aspx

The backup preferences tab will assist in choosing the type of backup and to prioritize the replica backups.

In the Listener tab, you will create an availability group listener button, Enter the string DNS name, enter port 1433 and enter the IP address for your listener, which should be an unused IP address on the network. 

Next, you will Select Initial Data Synchronization page, join the databases to the Always on group, then verify the Full option is selected for using File Shares. For large databases select Join or Skip to restore the databases to the secondary replica. We will use Full for now. Last thing to do here is remember the SQL Service accounts and set that all replicas have read/write permissions to the file Share or it will not work. 

Run the Validation checks, and make sure it the results are successful. 

That is it, once you get that done you should have High availability and AlwaysOn SQL Server. I hope you’ve enjoyed this instructional blog. Please come back and visit us to see other projects.

Custom WHMCS Modules

A WHMCS module is a third-party add-on that can be integrated into WHMCS to provide additional panel functionality or to connect to another service.

WHMCS Global Services, for example, could create a WHMCS plugin to help resellers of our servers streamline the server ordering process, or resellers could add server administration services to their client area.

Custom WHMCS modules are a great way to expand the panel's already extensive capabilities.

A module is a collection of functions that extend the functionality of the WHMCS platform and is most commonly used to integrate with third-party services and APIs.

The Key Advantages of Using a WHMCS Module

Increase Functionality – By adding a module to your WHMCS, you can increase its functionality and add custom features based on your needs and convenience.

Automation – Another significant benefit of using the WHMCS Module is automation. You can add modules to automate any of the functions related to payments, invoices, and client data that you dislike doing manually.

Integration – WHMCS Modules make it much easier to integrate WHMCS with other third-party APIs and apps. One can easily manage various aspects of their WHMCS, such as reporting, accounting, emails, and so on.

Ubuntu Start Docker On Boot

Docker is a combo of ‘platform as a service’ products and services which use OS virtualisation to provide software in packages called containers.

Ubuntu Start Docker Container On Boot

Ubuntu Start Docker Container On Boot

Ubuntu Start Docker On Boot Safe Mode

Ubuntu Start Docker On Bootable

Containers contain everything an app, tool or service needs to run, including all libraries, dependencies, and configuration files. Containers are also isolated from each other (and the underlying host system), but can communicate through pre-defined channels.

Ubuntu will download the latest version of Docker from its archives, unpack it, and install it on your system. Step 2: Make Docker start automatically on system boot: sudo systemctl enable -now docker. Step 3: Test it. Now that Docker is installed and running you should verify that everything is working okay. This can be done using the hello. A minimal Ubuntu base image modified for Docker-friendliness. Baseimage-docker only consumes 8.3 MB RAM and is much more powerful than Busybox or Alpine. Baseimage-docker is a special Docker image that is configured for correct use within Docker containers. It is Ubuntu, plus: Modifications for Docker-friendliness. To start a stopped container, use docker start, followed by the container ID or the container’s name. Let’s start the Ubuntu-based container with the ID of d9b100f2f636: docker start d9b100f2f636; The container will start, and you can use docker ps to see its status.

You need addtional settings to make it work.

This introduction to Docker video will give you a quick top-level overview of the tech and how it works:

Because Docker is open source software it’s not only free to use, but free to adapt, extend, hack, or build on. In this guide I cover installing Docker on Ubuntu 20.04 LTS (Focal Fossa), but the same steps may also work on older versions of Ubuntu, including Ubuntu 18.04 LTS.

In this post you will learn how to install Docker from the regular Ubuntu repository, how to enable Docker to start automatically at system boot, and how to install Docker images and run them locally.

But this isn’t a deep dive. This tutorial is intentionally short and to the point. This is so you spend less time reading and more time doing.

Install Docker from Ubuntu Repository

There are two hard requirements to install Docker on Ubuntu 20.04:

This MacBook Air is available by default with either 128 GB or 256 GB of SSD storage but it also could be configured with a 512 GB or 1.5 TB SSD at additional cost. The 512 GB storage originally was an extra US$400 or US$200 increase from the 128 GB and 256 GB options, respectively; and the 1.5 TB storage was an extra US$1200 or US$1000. The M1 chip brings superfast unified memory to MacBook Air. This single pool of high-bandwidth, low-latency memory allows apps to share data between the CPU, GPU, and Neural Engine efficiently — so everything you do is fast and fluid. Your MacBook Air comes standard with 8GB of memory and can be expanded to 16GB. Update itunes macbook air. Testing conducted by Apple in October 2020 using preproduction MacBook Air systems with Apple M1 chip and 8-core GPU, as well as production 1.2GHz quad-core Intel Core i7-based MacBook Air systems with Intel Iris Plus Graphics, all configured with 16GB RAM and 2TB SSD. Tested with prerelease Shapr3D 3.45.0 using a 288.2MB model. My Macbook Air is the old one bought in 2015, but I recently updated it to MacOS Catalina, so I followed the guide to reset it under your Catalina instructions. I managed to erase the Macintosh HD Data volume, but when I tried to erase Macintosh HD it said “Erase process has failed”.

Ubuntu Start Docker Container On Boot

You need to have sudo access

You need to be connected to the internet

If you’re managing or setting up an Ubuntu server then you (probably) meet both of these requirements already, but do check before you begin.

Step 1: Install Docker from the main Ubuntu repository. Do this using the apt command and the docker.io package name (note: the package name is not simply ‘docker’):

Ubuntu will download the latest version of Docker from its archives, unpack it, and install it on your system.

Download high sierra to usb. There are few applications that you need to download in-order to successfully create a bootable USB Flash Drive to install macOS High Sierra Windows 10 PC. High Sierra Bootable USB Installer FOR WINDOWS PC. The macOS High Sierra 10.13.2 update improves the stability, compatibility and security of your Mac, and is recommended for all users. This update:. Improves compatibility with certain third-party USB audio devices. Improves VoiceOver navigation when viewing PDF documents in Preview. Improves compatibility of Braille displays with Mail.

Step 2: Make Docker start automatically on system boot:

Step 3: Test it.

Now that Docker is installed and running you should verify that everything is working okay. This can be done using the hello-world app. From the command line run:

When you run this command you’ll see a lengthy message informing you that the ‘installation appears to be working correctly’.

But look closely at the message:

You’ll notice something interesting near the start: Docker was ‘unable to find’ the a ‘hello-world’ image. But instead of quitting it searched for and downloaded it from Docker Hub.

Ubuntu Start Docker Container On Boot

Which leads us neatly on to…

Step 4: Find and install Docker images.

Now you’re set-up the world (or rather the Docker ecosystem) is your oyster, and Docker Hub your port of call. Docker Hub is billed as ‘the world’s largest library and community for container images’. Any image available on Docker Hub can be installed on your system too.

Let’s look at how to do that.

To search for an image on Docker Hub run the docker command with the search subcommand, like so:

For example, I want to search for Alpine Linux on Docker Hub so I run docker search alpine. A list of matching images (which match the term alpine) will appear. I want the official Alpine image so I look in the OFFICIAL column for the word OK

When you find the image you want to use you can download it using the pull subcommand, For example, to install Alpine Linux I run sudo docker pull alpine.

Install docker on oracle linux 7. To run a downloaded image you need to add the run subcommand and the name of the image, e.g., sudo docker run alpine.

If you want to run an image as a container and get instant ‘interactive terminal’ shell access add the -it flag. For example: I run sudo docker run -it alpine and it drops me straight into the Alpine container, ready to work:

To exit the ‘interactive terminal’ type the word exit and hit enter.

Check out the Docker Docs page for a wealth more info on how to use, admin, manage, and maintain your containers.

Ubuntu Start Docker On Boot Safe Mode

A couple of useful commands to know include docker ps -a to list all images you’ve used (and see their container ID/name); docker stop (container id) to close an image down; and when you’re done with a container remove it using the docker rm command, again adding the the container ID/name at the end.

Ubuntu Start Docker On Bootable

Going Further

In this guide we looked at installing Docker on Ubuntu 20.04 and getting official images installed. But this is only the beginning of what possible with Docker.

One possible avenue to explore is installing Docker rootless. This is an experimental feature and not (yet) easy to enable. But the effort required to set it up is worth it if you’re concerned about security and stability.

If there are topics you want to see a similar to-the-point tutorial on (be it Docker related or otherwise) do drop a note down in the comments or via my usual e-mail.

vSphere Mobile Client App

Mobile and other handheld devices are becoming a part of our life by helping us keep up with every possible thing, may it be our health, our social life, or our work. vSphere Client product team wanted to enable admins to keep an eye on their datacenters using these handheld devices.

We are happy to announce that vSphere Mobile Client fling is released to help you monitor your datacenters and take some quick actions to continue running your workloads without any disruption. This lightweight app is available for download for both Android and iOS devices. This app is built using the same vSphere Client (HTML5) APIs, and is compliant with Clarity theme, thus maintaining the consistent data and experience across different vSphere management platforms. Released as a fling since the start of 2019, this app has all the modern mobile app features like Bio-metric authentication, optimized for the touch interface, and offline notification capabilities (more about this later).

The complete list of VMware Mobile Apps This list is limited to the applications that have VMware (and AirWatch) as developer or company in its descriptions. I know there are much more applications that you can use to manage your VMware infrastructure. Krishnamurti said VMware hopes to have the first phones with the VMware Mobile Virtualization Platform appear by late 2009 or early 2010. Top Picks In Shopping Shopping 5 Peloton bike alternatives.

Vmware Tools Device Drivers

vSphere Mobile Client is built keeping monitoring in mind. You can monitor the resource utilization by VMs, Hosts, Clusters, etc., for the same granular metrics as that of vSphere Client (HTML5). You can also monitor the status of tasks, events, or alarms in your environment. There are only a limited set of operations supported in the app to allow you to mitigate any issues you would notice while you monitor. Ex: a host is running out of resources in a DRS enabled cluster and you want to put a host into maintenance mode so DRS can vMotion your application causing zero downtime or you want to take a snapshot of a VM or power reset a VM for a quick fix or have a quick peek at the VM’s remote console. You cannot perform any advanced operations like configuring a cluster or performing manual vMotions thus reducing the risk of “fat fingering” mistakes.

Another cool feature supported by vSphere Mobile Client is offline monitoring of long-running tasks. Let’s assume you are putting a host into maintenance mode which will trigger a bunch of vMotion operations that could take a lot of time to complete. Wouldn’t it be nice to send a notification to your phone when the task completes, so you can open your laptop only if there are any failures? You could achieve this by configuring a notification appliance that monitors these long-running tasks and sends push notifications to your phone app on task completion.

To use the vSphere Mobile Client app, all you need is a VPN connectivity from your phone app to a vCenter server in your datacenter. If your enterprise uses any form of Mobile Device Management (MDM) software, then you can connect using the built-in VPN in the MDM. Since it’s release in 2019 we have seen a significant increase in adoption and usage of the app across the geography. Some of the future capabilities we are considering bringing in the app are: the ability to manage multiple linked vCenter servers including VMware Cloud on AWS, integration between vSAN monitoring app, customizable notifications, vSphere Skyline health integrations, and browser to mobile handoff capabilities.

Before we want to make vSphere Mobile client app as an officially supported product, we want to get feedback from you. Could you use the app and share the feedback using the in-app feedback capability? Let us know what other features support would make you use this app to monitor your production environment. You can leave general feedback comments in the Fling’s comments section or in the device App stores.

Enjoy the app and let us know what you think about it!

What happened to vSphere Mobile Watchlist?!

There used to be a mobile client to manage vSphere environment called vSphere Mobile Watchlist which was built a long time ago. Since this app was heavyweight, was not built to reuse the vSphere Client APIs, it was very expensive for us to enhance it to give a consistent experience. Rather we rebuilt the brand new lightweight vSphere Mobile client app. vSphere Watchlist is no longer supported/maintained.

Beginner’s Guide To Setup Kubernetes

Steps to install Kubernetes Cluster

Requirements

The major requirements are stated below regarding the setup process.

Master: 2 GB RAM 2 Cores of CPU Slave/ Node: 1 GB RAM 1 Core of CPU

1.Install Kubernetes

The below steps mentioned to be executed on both the master and node machines. Let’s call the master as ‘kmaster‘ and node as ‘knode‘.

1.1 Change to root:

Here, the changing root has been applied because the sudo provides permission to set up Kubernetes, and to avoid the permission process we have changed the root.‌

$ sudo su

# apt-get update

This command used to update a system.

1.2 Turn Off Swap Space:

Kubernetes doesn't support "swap". So we have to apply the below command to turn off the swap space.

# swapoff -a

1.3 Fstab action

After that, you need to open the ‘fstab’ file and comment out the line which has mention of swap partition.

# nano /etc/fstab

Press ‘Ctrl+X’, after that press ‘Y’ and then press ‘Enter’ to Save the file.

1.4 Update The Hostnames

To change the hostname of both machines, run the below command to open the file and subsequently rename the master machine to ‘kmaster’ and your node machine to ‘knode’.

# nano /etc/hostname

Press ‘Ctrl+X’, after that press ‘Y’ and then press ‘Enter’ to Save the file.

1.5 Update The Hosts File With IPs Of Master & Node

Run the following command on both machines to note the IP addresses of each.

# ifconfig

Now go to the ‘hosts’ file by moving over the both master and node and add an Entry by just specifying their respective IP addresses along with their names i.e. ‘kmaster’ and ‘knode’.

# nano /etc/hosts

Press ‘Ctrl+X’, after that press ‘Y’ and then press ‘Enter’ to Save the file.

1.6 Setting Static IP Addresses

We will make the IP addresses used as above, static for the VMs. We can do, by just modifying/changing the network interfaces file. Then, run the following command to open the file:

# nano /etc/network/interfaces

Now enter the following lines in the file.

auto enp0s8 iface enp0s8 inet static address

Press ‘Ctrl+X’, after that press ‘Y’ and then press ‘Enter’ to Save the file.

After this, restart your machine.

1.7 Install Open SSH-Server

Now we have to install openshh-server. Run the following command:

# sudo apt-get install openssh-server

2. Install Docker

Now we need to install Docker as docker images will be utilized for managing the containers in the cluster. Run with the following commands:

# sudo su # apt-get update # apt-get install -y docker.io

We’ve just explained about how to docker in your own system instead the process of how to add a $user in a docker or how to install docker-compose, for the basics of kubernetes you can follow by just tapping over this link:

3. Install kubeadm, Kubelet And Kubectl

To move further, we’ve to Install these 3 essential components for just setting up the environment of Kubernetes: kubeadm, kubectl, and kubelet.

Run the following commands before installing the Kubernetes environment.

# apt-get update && apt-get install -y apt-transport-https curl # curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - # cat <<EOF >/etc/apt/sources.list.d/kubernetes.list deb http://apt.kubernetes.io/ kubernetes-xenial main EOF # apt-get update

Kubelet is the lowest level component in Kubernetes. It’s reliable for what’s running on an individual or specific machine.

Kubeadm is used for administrating the Kubernetes cluster.

Kubectl is used for controlling the configurations on various nodes inside the cluster.

# apt-get install -y kubelet kubeadm kubectl

3.1 Updating Kubernetes Configuration

Next, we will change the configuration file of Kubernetes. Run the following command:

#nano /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

This will open a text editor, enter the following line after the last “Environment Variable”:

Environment="cgroup-driver=systemd/cgroup-driver=cgroupfs"

Press ‘Ctrl+X’, after that press ‘Y’ and then press ‘Enter’ to Save the file.

4. Steps Only For Kubernetes Master VM (kmaster)

All the required packages were installed on both servers till now. But, the further steps will work upon the Master Node only. Now, run the following command to initialize the Kubernetes Master.

4.1 Initialize Kubernetes Master with ‘kubeadm init’

Run the beneath command to  initialize and setup kubernetes master.

# kubeadm init (or) # kubeadm init --apiserver-advertise-address=<ip-address-of-kmaster-vm> --pod-network-cidr=192.168.0.0/16 # kubeadm init --apiserver-advertise-address 192.168.1.206 --pod-network-cidr=172.16.0.0/16

In the selected part 1, when we initialize Kubeadm with the command then it will show you the kubernetes control-panel has initialized successfully. The three commands as shown in the images’ part 1 should be run to create .kube folder.

As mentioned before, run the commands from the above output as a non-root user

$ mkdir -p $HOME/.kube $ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config $ sudo chown $(id -u):$(id -g) $HOME/.kube/config

In the selected part 2, signifies about the “kubeadm join token”. The kubeadm token need to store somewhere in notepad and wherever you want to. After storing, you need to run that specific key token in a node terminal so that it can maintain the communication between the master and node.

You will notice from the previous command, that all the pods are running except one: ‘kube-dns’. For resolving this we will install a pod network. To install the CALICO pod network, run the following command:

$ kubectl apply -f https://docs.projectcalico.org/v3.0/getting-started/kubernetes/installation/hosted/kubeadm/1.7/calico.yaml

Install network add-on to enable the communication between the pods only on master nodes. Flannel is a network fabric for the containers, that are designed for the kubernetes.  

$ kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

To verify, if kubectl is working or not, run the following command.s

$ kubectl get pods -o wide --all-namespaces

use "kubectl get nodes" command to ensure the kubernetes master node status is ready.

$ kubectl get nodes

4.2 To reset kubernetes

Now, if you are done with the process of initiating the command and requiring a fresh start, then you can make changes by just following the below command.

$ kubeadm reset

5. Steps For Only Kubernetes Node VM (knode)

For trial purpose, we can create nodes in the same system with the help of virtual machine.

Prerequisites

1.3GHz or faster 64-bit processor 2 GB RAM minimum/ 4GB RAM or more recommended

install vmware workstation player on ubuntu

5.1 Install required packages

$ sudo apt update $ sudo apt install build-essential</strong> $ sudo apt install linux-headers-$(uname -r)

5.2 Download vmware workstation player

$ wget https://www.vmware.com/go/getplayer-linux

Once the download is completed make the installation file executable using the following command:

$ chmod +x getplayer-linux

5.3 install vmware workstation player

Start the Installation wizard by typing:

$ sudo ./getplayer-linux

1. Just accept the terms and conditions in the license agreement and click on the Next button.

2. Next, you will be asked whether you like to check for product updates on startup. Make your selection and click on the Next button.

3. VMware’s Customer Experience Improvement Program (“CEIP”) helps VMware to improve their products and services by sending anonymous system data and usage information to VMware. If you prefer not to participate in the program select No and click on the Next button

4. In the next step , if you don’t have a license key, vacate the field empty and click on the next button.

5. Next, you will see the following page informing you that the VMware Workstation Player is ready to be installed. Click on the Install button.

6. Start VMware Workstation Player

Create a new virtual machine

Open terminal in virtual system and follow the step to create user (knode) and enter command to make connection between master and node.

$ sudo su

Now we are in the ‘knode terminal’ and we need to run kubeadm init. token key in this terminal as we have described above to save the specific key so that it make connection between master( kmaster) and node(knode).

# kubeadm join 192.168.1.206:6443 --token 02p54b.p8oe045cpj3zmz2b --discovery-token-ca-cert-hash sha256:50ba20a59c9f8bc0559d4635f1ac6bb480230e173a0c08b338372d8b81fcd061

once worker node is joined with kubernetes master, then verify the list of nodes within the kubernetes cluster.

$ kubectl get nodes

we have successfully configured the kubernetes cluster.

kubernetes master and worker node is ready to deploy the application.

Bottom Line

Now that we have explained about kubernetes setup, and further we will move onto something more technical with the other parts of this kubernetes series. Our next tutorial would explain to you how to make a connection with dashboard. Till then enjoy learning and try something new.

Configuración y gestión de redes – Redes PYME

¡Hola amigas y amigos!

Índice general de la serie: Redes de Computadoras para las PYMES: Introducción

Aun no hemos dedicado un artículo al tema que origina el título de éste. Tampoco hemos leído algún comentario pidiendo se escriba sobre él. Dimos por sentado que era del conocimiento de todos y tal vez fue la causa de que lo obviamos hasta hoy. No obstante, escribiremos un sucinto post al respecto para aquellos que necesiten refrescar o aprender sobre el tema.

Red: definición práctica

Para propósitos prácticos, una Red – Network consiste de dos o mas dispositivos de redes tales como computadoras, servidores, impresoras, teléfonos móviles, u otros equipos de redes, que se conectan mediante cables físicos o enlaces inalámbricos con el propósito de compartir y distribuir información entre los dispositivos conectados.

Configuración De Servidores Con GNU/Linux

Recuerden que los enlaces los damos con plena intención y no por gusto.

Configuración de red

Recomiendo a los que utilizan los sistemas operativos CentOS y openSUSE, se guíen por el texto Configuración De Servidores Con GNU/Linux, del autor Joel Barrios Dueñas. Me es difícil redactar los temas que trataremos a continuación para las distribuciones Debian, CentOS y openSUSE en un mismo artículo, pues las últimas dos difieren de la primera sobre todo en nombres, ubicación de archivos de configuración, sus contenidos, y algún que otro aspecto filosófico relacionado con el tema.

Los sistemas operativos que utilizamos a lo largo de ésta serie disponen de herramientas gráficas para la configuración de los diferentes dispositivos de red. Sin embargo, este post se centrará en el uso de la consola de comandos o terminal.

Como hemos visto en artículos anteriores, en la mayoría de las ocasiones configuramos la interfaz de red -o las interfaces- durante el proceso de instalación para garantizar que, una vez se haya instalado el sistema operativo base, el equipo cuente con una eficaz conexión de red.

La correcta configuración de al menos la primera interfaz de red -principal- es vital para el posterior trabajo del Desktop, Workstation, o Server que estemos implementando.

No usaremos NetworkManager

Para simplificar la redacción de éste artículo, centrar la atención en la configuración de servidores, y facilitar su lectura, asumiremos que no se está utilizando el servicio que brinda el paquete network-manager. En caso contrario debemos ejecutar las siguientes acciones:

En Debian

buzz@sysadmin:~$ sudo systemctl stop network-manager.service buzz@sysadmin:~$ sudo systemctl status network-manager.service buzz@sysadmin:~$ sudo systemctl disable network-manager.service buzz@sysadmin:~$ sudo ifconfig

Si la configuración de las tarjetas de red que dependían del servicio network-manager son correctas, entonces podemos continuar trabajando. No obstante es saludable ejecutar:

buzz@sysadmin:~$ sudo ifdown eth0 && sudo ifup eth0

para volver a comprobar que todo funciona bien.

En CentOS

En el libro en formato PDF “Configuración De Servidores Con GNU/Linux“, Edición de Julio 2016, se dedica el capítulo 48.2.2 al tema del servicio NetworkManager. Les adelanto que a su autor Joel Barrios Dueñas, no le agrada para nada -lo considera absurdo- el uso del NetworkManager en Servidores.

Interfaces Ethernet

Por regla general, cuando trabajamos con máquinas virtuales sobre Qemu-KVM, el sistema operativo identifica a las Interfaces Ethernet con nombres como ethX, donde la X representa a un valor numérico. La primera interfaz Ethernet se identifica como eth0, la segunda como eth1 y así sucesivamente.

Si se trata de los sistemas operativos Debian -y derivados- ejecutados sobre máquinas físicas, también se cumple la notación anterior.

Si trabajamos sobre máquinas físicas con los sistemas operativos CentOS y openSUSE, el sistema operativo las identifica como enoX. Tanto parecido puede suceder con máquinas virtuales -con éstos sistemas operativos- sobre hipervisores de la VMware.

En máquinas virtuales creadas a partir del sistema operativo FreeBSD -que es también Software Libre- se identifican generalmente como emX o vtnetX según sean sobre Qemu-KVM o sobre VMware respectivamente. Si son físicas se identifican típicamente como emX.

Identificar las Interfaces Ethernet

Para identificar todas las interfaces de red disponibles en mi equipo sysadmin.desdelinux.fan, ejecutamos:

Los tres puntos suspensivos en las salidas anteriores significa que se devuelve mucha mas información que no reflejamos para ahorrar espacio.

Como tengo instalado sobre el sistema operativo Debian 8 “Jessie” a dos programas soporte de máquinas virtuales, o sea, Qemu-KVM y VMware Workstation Server 10.0.6, el comando devuelve todas las interfaces existentes.

Que conste: el software privado VMware Workstation Server 10.0.6 es una copia legal obsequiada por mi amigo y colega El NeoZelandes, que la adquirió vía Internet en su país natal y tuvo la amabilidad de enviármela.

Veamos que información podemos obtener de la salida anterior:

eth0: Interfaz principal de red con la dirección IPv4 10.10.10.1. También se muestra la dirección IPv6.

lo: Loopback o local con la IPv4 127.0.0.1 y la IPv6 -común a todas éstas interfaces- ::1/128.

virbr0: Interfaz de red tipo Puente –  Bridge con la IPv4 192.168.10.1 y con la dirección MAC 52:54:00:c8:35:5e. Esta interfaz virtual es la que creamos y configuramos mediante el Virt-Manager del Qemu-KVM como red “default” del tipo NAT.

virbr0-nic: Interfaz de red que crea el Qemu-KVM, de tipo Puente Anónimo- Anonymous Bridge y con la misma dirección MAC 52:54:00:c8:35:5e que virbr0. No tiene asignada dirección IP.

vmnet8: Interfaz de red tipo NAT configurada en el VMware Virtual Network Editor.

El VMware Workstation Server vía su Virtual Network Editor, configura de forma distinta a los Puentes que crea con cada una de las interfaces físicas del Anfitrión – Host. ¿Les suena conocida la jerga utilizada en artículos anteriores?.

Otra aplicación -que no la única ni última- para obtener información acerca de las interfaces de red es lshw – List Hardware. lshw es una herramienta que extrae información detallada sobre la configuración de la máquina. Si ejecutamos en una consola:

buzz@sysadmin:~$ aptitude search lshw p lshw - information about hardware configuration p lshw-gtk - graphical information about hardware configuration

Observamos que incluso tiene su interfaz gráfica la cual dejamos para que Usted la pruebe. Instalemos la del modo consola y ejecutemos a continuación:

buzz@sysadmin:~$ sudo lshw -class network [sudo] password for buzz: *-network description: Ethernet interface product: 82579V Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 05 serial: 70:54:d2:19:ad:65 size: 100Mbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master ... *-network DISABLED description: Ethernet interface physical id: 1 logical name: virbr0-nic serial: 52:54:00:c8:35:5e size: 10Mbit/s capabilities: ethernet physical

Administremos los nombre lógicos de las interfaces

En algunas ocasiones, sobre todo cuando cambiamos una tarjeta de red física por cualquier motivo, observamos que el número X que identifica a la interfaz aumentó en 1 y solo nos percatamos de ello cuando ejecutamos ifconfig -a, en medio de la situación que ocurrió después del cambio. También puede suceder cuando quitamos una interfaz de red virtual por cualquier razón, y después volvemos a añadir otra.

Lo anterior puede resultar molesto cuando hemos configurado y enlazado – bind a uno o mas servicios, un determinado nombre lógico de interfaz, sea ésta eth0, eno1 o em0.  Lo mas inoportuno es que casi siempre sucede mucho tiempo después -años quizás- de la inicial configuración. Entonces aparecen nuevas interfaces con nombres como eth1,eth2, eno2, em1, etcétera, y algunos servicios dejan de funcionar correctamente. Los que han atravesado por parecidas situaciones saben a que me refiero.

Los nombres lógicos de las interfaces de red en Debian -y algunos de sus derivados- se encuentran el archivo /etc/udev/rules.d/70-persistent-net.rules. En CentOS 7 se encuentra en el archivo /etc/udev/rules.d/90-eno-fix.rules, mientras que en sus versiones anteriores es el mismo archivo que en Debian.

En Debian, si Usted quiere cambiar el nombre lógico de una interfaz de red en particular, busque la línea correspondiente a su dirección MAC y modifique el valor NAME=ethX por el valor de nombre lógico que necesite. Para que los cambios se realicen correctamente, debe reiniciar el equipo.

Para CentOS 7, consulte la obra “Configuración De Servidores Con GNU/Linux” de Joel Barrios Dueñas, en la que se brinda un detallado método.

Importante: En cualquier caso, ¡Cuidado! con el servicio NetworkManager en caso de que esté manejando las conexiones.

Modificar los parámetros de las interfaces de red

En Debian, si queremos modificar los parámetros de una tarjeta de red de forma permanente, debemos editar el archivo /etc/network/interfaces como veremos mas adelante.

Para conocer en detalle -y más- todas las opciones que puede utilizar consulte man interfaces. También recomendamos lea la documentación existente en la carpeta:

buzz@sysadmin:~$ ls -l /usr/share/doc/ifupdown/ total 44 drwxr-xr-x 2 root root 4096 ago 7 2016 contrib drwxr-xr-x 2 root root 4096 ago 7 2016 examples -rw-r--r-- 1 root root 976 jun 21 2012 copyright -rw-r--r-- 1 root root 18243 mar 13 2015 changelog.gz -rw-r--r-- 1 root root 297 jun 21 2012 NEWS.Debian.gz -rw-r--r-- 1 root root 454 nov 29 2014 README -rw-r--r-- 1 root root 946 jun 21 2012 TODO

Programa ethtool

Por medio del programa ethtool podemos consultar, listar y modificar los parámetros de una tarjeta de red tales como velocidad de conexión, negociación automática, suma chequeo fuera de carga – check sum offload, etcétera. Se encuentra disponible en los repositorios de casi todas las distribuciones.

buzz@sysadmin:~$ sudo aptitude install ethtool [sudo] password for buzz: buzz@sysadmin:~$ sudo ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: on (auto) Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes

Los cambios que realicemos mediante ésta herramienta son temporales y se perderán en el próximo reinicio del equipo. Si necesitamos de modificaciones permanentes hechas mediante ethtool, debemos agregar en el archivo /etc/network/interfaces una directiva “pre-up” o “antes de levantar la interfaz” de la forma siguiente:

auto eth1 iface eth1 inet dhcp pre-up /sbin/ethtool -s eth1 speed 1000 duplex full

Así, la tarjeta de red eth1 la cual obtiene su dirección IP de un servidor DHCP, queda modificada de forma permanente para que funcione a la velocidad de 1000 Mb/s en modo Full Duplex.

El método anterior también es válido para tarjetas con IP estáticas.

Direccionamiento IP

Veremos a continuación cómo configurar la dirección IP del equipo, así como la puerta de enlace – gateway por defecto, necesarias para la comunicación con el resto de la red local y directamente con Internet a través de su gateway.

Cuando escribimos “directamente” nos referimos a los casos de redes PYME en que se permite el acceso a Internet sin el uso de un servidor Proxy, lo cual no se recomienda, aunque exista un poderoso Firewall en el propio equipo que funciona como Gateway. Cuando llegue su turno tocaremos el tema Proxy.

Direccionamiento temporal

Mediante comandos estándares de cualquier distribución Linux como ip, ifconfig y route, podemos configurar de manera temporal una interfaz de red como veremos a continuación.

Para asignar una dirección IP y su máscara de subred y después comprobar la operación ejecutemos:

buzz@sysadmin:~$ sudo ifconfig eth0 172.16.10.2 netmask 255.255.0.0

buzz@sysadmin:~$ sudo ifconfig eth0 Link encap:Ethernet HWaddr 70:54:d2:19:ad:65 inet addr:172.16.10.2 Bcast:172.16.255.255 Mask:255.255.0.0 inet6 addr: fe80::7254:d2ff:fe19:ad65/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:659 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:115601 (112.8 KiB) Interrupt:20 Memory:fe600000-fe620000

Acabamos de asignar temporalmente a la tarjeta eth0 la dirección IP estática 172.16.10.2 con máscara de subred 255.255.0.0 perteneciente a una Red Privada Internet Clase “B”.

Observen que hemos modificado la configuración de la interfaz de red eth0 del propio equipo sysadmin.desdelinux.fan que antes tenía la IP 10.10.10.1/255.255.255.0 perteneciente a una Red Privada Internet Clase “A”, aunque solamente pueda albergar a 254 equipos acorde a su máscara de subred.

Para configurar el Gateway por defecto y después comprobar la operación ejecutemos:

buzz@sysadmin:~$ sudo route add default gw 172.16.10.1 eth0 buzz@sysadmin:~$ sudo route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 172.16.10.1 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 172.16.10.1 0.0.0.0 UG 1024 0 0 eth0 172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet8 192.168.20.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0

Acabamos de asignar temporalmente el Gateway 172.16.10.1 a la interfaz eth0 172.16.10.2, mientras que las demás interfaces mantienen sus valores anteriores.

Para eliminar TODAS las configuraciones de la tarjeta de red, ejecutemos:

buzz@sysadmin:~$ sudo ip addr flush eth0 buzz@sysadmin:~$ sudo ifconfig eth0 Link encap:Ethernet HWaddr 70:54:d2:19:ad:65 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:718 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:125388 (122.4 KiB) Interrupt:20 Memory:fe600000-fe620000 buzz@sysadmin:~$ sudo route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet8 192.168.20.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0

¡Observemos bien, pues eliminamos TODAS las configuraciones de red anteriores incluso la declarada en el archivo /etc/network/interfaces!.

Para regresar el mundo a como estaba antes podemos reiniciar el equipo. Sino queremos parar de trabajar ejecutemos:

buzz@sysadmin:~$ sudo ifconfig eth0 10.10.10.1 netmask 255.255.255.0 buzz@sysadmin:~$ sudo ifconfig eth0 eth0 Link encap:Ethernet HWaddr 70:54:d2:19:ad:65 inet addr:10.10.10.1 Bcast:10.10.10.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:729 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:129009 (125.9 KiB) Interrupt:20 Memory:fe600000-fe620000 buzz@sysadmin:~$ sudo route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet8 192.168.20.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0

y así regresamos a la configuración original.

Direccionamiento temporal mediante el comando ip

En muchas ocasiones nos movemos con una Portátil – Laptop a otra Red PYME que solicitó nuestros servicios o ayuda y no queremos modificar la configuración general de su interfaz de red. Para lograrlo podemos utilizar el comando ip.

El comando ip se instala con el paquete iproute, o el iproute2 según la distribución y versión. En Debian 6 “Squeeze” –a nuestro juicio muy personal– las páginas del manual del comando ip eran mucho mas explícitas que las de por ejemplo, Wheezy y Jessie. ip si se continúa utilizando para mostrar, o manipular el encaminamiento – routing, dispositivos, políticas de encaminamiento y túneles.

Puede consultar las páginas del manual de la versión instalada mediante man ip.

Lo he utilizado solamente para asignar otra dirección IP correspondiente a la subred de la LAN PYME de otra empresa. Ejemplo, asignemos la dirección IP 192.168.1.250 además de la que ya tiene y que es la 10.10.10.1 a la tarjeta de red de mi computadora:

buzz@sysadmin:~$ ip addr show eth0 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 70:54:d2:19:ad:65 brd ff:ff:ff:ff:ff:ff inet 10.10.10.1/24 brd 10.10.10.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::7254:d2ff:fe19:ad65/64 scope link valid_lft forever preferred_lft forever buzz@sysadmin:~$ sudo ip addr add 192.168.1.250/24 broadcast 192.168.1.255 dev eth0 buzz@sysadmin:~$ ip addr show eth0 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 70:54:d2:19:ad:65 brd ff:ff:ff:ff:ff:ff inet 10.10.10.1/24 brd 10.10.10.255 scope global eth0 valid_lft forever preferred_lft forever inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::7254:d2ff:fe19:ad65/64 scope link valid_lft forever preferred_lft forever

Aunque en la salida del comando se refleje que el cambio es válido para siempre

valid_lft forever preferred_lft forever

realmente no sucede tal cosa, lo cual podemos comprobar si inhabilitamos e inmediatamente después habilitamos la interfaz en cuestión mediante los comandos ifdow eth0 && ifup eth0. Si no queremos reiniciar la interfaz y devolver a eth0 a su estado inicial, ejecutamos:

buzz@sysadmin:~$ sudo ip addr del 192.168.1.250/24 broadcast 192.168.1.255 dev eth0 buzz@sysadmin:~$ ip addr show eth0

Para conocer los comandos que instala el paquete iproute2 ejecutemos:

buzz@sysadmin:~$ sudo dpkg -L iproute2 | grep /bin buzz@sysadmin:~$ sudo dpkg -L iproute2 | grep /sbin

Direccionamiento Dinámico

Si queremos que un equipo obtenga una dirección IP dinámica debemos configurar su interfaz de red de forma que la obtenga vía el dhclient. Solo debemos declarar en el archivo /etc/network/interfaces las siguientes líneas para esa interfaz:

auto eth0 iface etho inet dhcp

Si durante el proceso de instalación se decidió que la tarjeta de red obtenga una IP dinámica, el paso anterior no es necesario pues debe estar correctamente configurada para que arriende una IP del servidor DHCP existente en la Red PYME.

Si se trata de que cambiamos de una IP Estática a una Dinámica, o que agregamos una nueva interfaz y queremos adquiera una IP dinámica, para habilitar a esa interfaz ejecutamos

buzz@sysadmin:~$ sudo ifup eth0

comando que en éste caso instruye al programa dhclient que inicie el proceso DHCP. Para inhabilitar la interfaz ejecutamos

buzz@sysadmin:~$ sudo ifdown eth0

comando que inicia el proceso de liberación – release de la configuración mediante DHCP y apaga la interfaz de red.

Ejecute man dhclient para obtener mas información sobre el programa cliente DHCP.

Direccionamiento estático

Hemos visto en muchos artículos anteriores como se configura una IP estática en una interfaz de red. El archivo de configuración principal es /etc/network/interfaces. Ejemplo:

buzz@sysadmin:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 iface eth0 inet static address 10.10.10.1/24 netmask 255.255.255.0 network 10.10.10.0 broadcast 10.10.10.255 gateway 10.10.10.101 # dns-* options are implemented by the # resolvconf package, if installed dns-nameservers 192.168.10.5 dns-search desdelinux.fan

Los parámetros de configuración de la interfaz de red eth0 del archivo anterior indican:

allow-hotplug eth0: Sinónimo de “auto” y “allow-auto“. Línea que indica que la interfaz física eth0 se debe levantar – up de forma automática por varios subsistemas durante el arranque del equipo. Típicamente mediante ifup

iface eth0 inet static: línea que indica que la interfaz – iface eth0 se debe configurar para una red TCP/IP IPv4 de forma estática -IP fija- y no dinámica, como ocurre en el caso del Direccionamiento Dinámico con la línea iface eth0 inet dhcp

address 10.10.10.1: asígna la IPv4 10.10.10.1 a la interfaz

netmask 255.255.255.0: máscara de subred de una típica LAN Clase “C” de hasta 254 equipos. Sinónimo de haber declarado address 10.10.10.1/24 en la línea anterior

network: subred a la cual pertenece la dirección estática asignada

broadcast: IP de difución o de anuncio

gateway: pasarela para conectarse típicamente a Internet

dns-nameservers: dirección IP del servidor DNS si está instalado el paquete resolvconf el cual no se debe confundir con el archivo /etc/resolv.conf – ó resolver

dns-search: dominio de búsqueda por defecto en consultas DNS

El contenido del archivo anterior se puede simplificar a :

buzz@sysadmin:~$ cat /etc/network/interfaces auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet static address 10.10.10.1/24 buzz@sysadmin:~$ ip addr show eth0 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 70:54:d2:19:ad:65 brd ff:ff:ff:ff:ff:ff inet 10.10.10.1/24 brd 10.10.10.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::7254:d2ff:fe19:ad65/64 scope link valid_lft forever preferred_lft forever

Todos los demás parámetros tomarán los valores por defecto, sin olvidar los valores que tenemos declarados en el archivo /etc/resolv.conf al NO tener instalado el paquete resolvconf.

Conexiones Puente – Bridge

Para hacer un Puente – Bridge es necesario instalar el paquete bridge-utils:

buzz@sysadmin:~$ sudo aptitude install bridge-utils

Los Puentes son muy utilizados en la Virtualización. Digamos que tenemos un servidor HP Proliant ML 350 Gen 8 o Gen 9 con 4 interfaces de red. Podemos dejar a una de ella para comunicarnos directamente con el Anfitrión – Host que da soporte a las máquinas virtuales. Con las tres restantes podemos hacer un Puente Anónimo –sin asignarle alguna dirección IP– y conectar a ese puente las máquinas virtuales para que accedan a la LAN PYME, tengan éstos equipos virtuales direcciones IP estáticas o dinámicas.

Éste muy útil tip me lo dio mi amigo y colega Eduardo Noel. También, en el archivo /usr/share/doc/ifupdown/examples/bridge encontraremos un guión – script sobre cómo hacer un bridge con varias interfaces de red.

buzz@anfitrion:~$ sudo nano /etc/network/interfaces auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet static address 192.168.10.27 iface eth1 inet manual iface eth2 inet manual iface eth3 inet manual # Bridge Anónimo iface br0 inet manual bridge_ports eth1 eth2 eth3

Resumen

El tema de las Telecomunicaciones es peliagudo y requiere de mucho estudio y práctica. Los Sysadmin necesitamos conocer lo esencial. Éste artículo es solo un Mínimo Puntito de Entrada. No más.

No hemos tocado -ni tocaremos- el Modelo OSI “Open System Interconnection” que es el modelo de referencia para los protocolos de la red con arquitectura en capas creado en el año 1980 por la Organización Internacional de Normalización “ISO“.

Descender en los aspectos teóricos del Modelo OSI, casi que equivale a descender a la Web Profunda o Deep Web… al menos para mi que no soy un Hacker.
