El problema viene cuando en lugar de instalar un PC en 40 minutos, tenemos que instalar 20, cada uno de esos pc’s, aunque podamos ir con varios discos a la vez, nos va a llevar más de 40 minutos hacer la instalación, por tener que ir siguiendo el asistente, escogiendo (...)

userChrome.css Firefox tiene en la carpeta del usuario, y dentro del perfil una subcarpeta llamada chrome y en ella el fichero userChrome.css
Éste permite ajustar pequeños cambios en el diseño como mostrar u ocultar menús, botones, etc.
Por ejemplo, podemos esconder el menú de ayuda con: #helpMenu display: none !important;

LVM introduces a separation between system structure and elements like disks, partitions, filesystems to which we are used to.
LVM has three levels: Physical volumes Volume Groups Logical volumes
One of the benefits of LVM over traditional systems is that LVM introduces an abstraction layer which (...)

Introduction
SELinux is an implementation of MAC over LSM in Linux Kernel.
SELinux, originally developed by N.S.A. allows applications to be confined by the kernel.
Inside that "confined area", much more grained than a standard chroot, in which we can allow only certain operations, for example: adding information to a file, read from a directory but not writing, even just for one file in a standard directory, etc...

Introduction
Jigdo (JIGsaw DOwnload) is a small utility that can assemble a CD/DVD image from it’s internal files.
For example, Debian has been using it for years for distributing the entire distribution: you downloaded a .jigdo file, and then, using the utility jigdo-lite (package jigdo-file on Debian like and RPM based. This way, you only downloaded small files from servers, preventing line failures, spreading load between several servers, etc.
Furthermore, if you already had some (...)

As it should, we provided services for a client, also very concerned about security, thus not allowing internet access despite of using two squid proxys with a network appliance filtering protocols, scripts, viruses and malware. They only allow FTP, HTTP and HTTPS.
¿What to do when you need to access (...)

Prior to using the following info for creating own-made packages, let’s test if everything is working fine.
I’ve created a NSIS script that writes into registry in a key called HKLM\SOFTWARE\OCS and puts a key named "cert" with value "creilla".
If we create a package with action "LAUNCH", and attach the regcert.zip with command to execute "regcert.exe", all clients with functional package deployment, will add that key to registry, so we can check, using OCS registry query function for (...)
