Activar SSL en IIS con un certificado digital de prueba

¿Qué es SSL?

SSL es un protocolo que permite la comunicación de nuestro navegador con el servidor a través de un canal seguro. Este canal seguro se consigue encriptando las comunicaciones y su función es impedir que terceras personas intercepten lo que estamos enviando y nos espíen para conseguir nuestros datos privados.

En general, distinguiremos si estamos accediendo a una página web sobre SSL cuando utilicemos el protocolo https en lugar de http. Además, nuestro navegador generalmente recalcará que la página web es segura mediante un icono de un candado, en el que podemos pinchar para ver en detalle la información sobre el certificado de seguridad del sitio web al que accedemos.

Activar el soporte SSL a Microsoft IIS

http://www.adictosaltrabajo.com/tutoriales/tutoriales.php?pagina=iisssl

Cuando navegamos por páginas Web, estamos siempre expuestos a que los datos que transmitimos sean interceptados …..

Para evitar este problema, los servidores pueden activar la seguridad, de tal modo que se encripta la comunicación, asegurándonos que nadie puede leer lo que estamos enviando. Para algunos tipos de servicios, donde se intercambian datos personales … esto es vital.

Os sonará que se utilizas https en vez de http… es decir http con soporte seguro SSL

Replacing a Shared Disk on a 2008 Failover Cluster

http://blogs.technet.com/b/askcore/archive/2011/08/26/replacing-a-shared-disk-on-a-2008-failover-cluster.aspx

Several months ago, I posted a blog on adding a new disk to an existing cluster. Another question we get asked a lot is “How do I replace a disk?”

In this blog, I’ll walkthrough the process of replacing a 1GB disk with a 2GB disk. This process is similar to how you could go about doing a SAN migration where you are replacing all of your shared disks with storage from a new SAN.

The preferred way of getting a larger cluster disk is to use the built in capability of most SANs to dynamically expand a LUN then use an OS utility like DiskPart or Disk Manager to extend the size of the disk. If that’s not feasible or you simply want to replace a LUN with a larger one or as I mentioned, as part of a SAN migration, this process works well.

The first thing we need to do is present your new disk to the cluster. The nuts and bolts of how to do that are outside the scope of this post so just ask your SAN administrator for a new LUN and present it to all nodes of the cluster. Since by default in Server 2008, we leave new LUNs offline, there’s no risk in presenting a new LUN to all nodes at the same time. In the below figure is what Disk Manager would look like after my new disk had been presented.
