10. Designing Organization-Wide Group Policies

Joe Richards O'Reilly Media ePub

This chapter takes an in-depth look at Group Policy Objects (GPOs ), focusing on three areas:

How GPOs work in Active Directory

How to manage GPOs with the Group Policy Object Editor and Group Policy Management Console

How to structure your Active Directory effectively using Organizational Units and groups so that you can make the best use of the GPOs required in your organization

Group policies are very simple to understand, but their uses can be quite complex. Each GPO can consist of two parts: one that applies to a computer (such as a startup script or a change to the system portion of the registry) and one that applies to a user (such as a logoff script or a change to the user portion of the registry). You can use GPOs that contain only computer policies, only user policies, or a mixture of the two.

GPOs themselves are stored in two places: Group Policy Configuration (GPC ) data is stored in Active Directory, and certain key Group Policy Template (GPT ) data is stored as files and directories in the system volume. They are split because while there is definitely a need to store GPOs in Active Directory if the system is to associate them with locations in the tree, you do not want to store all the registry changes, logon scripts, and so on in Active Directory itself. To do so could greatly increase the size of your DIT file. To that end, each GPO consists of the object holding GPC data, which itself is linked to a companion directory in the system volume that may or may not have GPTs stored within. The GPT data is essentially a folder structure that stores Administrative Template-based policies, security settings, applications available for software installation, and script files. GPT data is stored in the System Volume folder of DCs in the Policies subfolder.

Matrimonio, honores y el noble arte de crearse enemigos (1888-1890)

Jp. A. Calosse Parkstone International PDF

de desnudo al pastel que causó furor. Whistler permaneció en el centro de la escena pública y concedió entrevistas.

Para dar a conocer su obra en el extranjero, realizó viajes a Holanda, Bélgica y Francia, y escribió profusamente acerca de su concepto de la pintura. La señora D’Oyly Carte, propietaria del Savoy Theatre de Londres, ofreció a Whistler la oportunidad de dar una conferencia en el teatro y se mostró tan entusiasta ante aquel acontecimiento como el propio pintor. En la gran noche del 20 de febrero de 1885, el vestíbulo estaba repleto de gente. Los periodistas, intrigados, se preguntaban qué sería lo que estaban a punto de oír.

Whistler ofreció un discurso sencillo que no permitía a los críticos atacarle sobre trivialidades. Tan pronto como dio comienzo la conferencia, los asistentes cayeron rendidos a sus pies, sobre todo cuando Whistler empezó a hablar acerca de cómo Londres se transfiguraba por la noche.

Un tal F. Day escribió: “Acudí a aquella conferencia a divertirme. Pero permanecí allí para admirar al orador”. El público, concentrado en las excentricidades de Whistler, había olvidado que el pintor tenía unas ideas serias acerca de su arte. Whistler reservó un trato muy especial para sus enemigos, los críticos. Para él, un crítico de arte que no es artista carece de toda autoridad: lo ve todo, salvo lo esencial.

3. Postfix Architecture

Kyle D. Dent O'Reilly Media ePub

You can easily manage and operate Postfix without understanding everything about how it works. If you're ready to dive right in, you can skip this section and start at the beginning of the next chapter. It might be difficult to digest all of the material here if you don't have much experience with Postfix yet, but this chapter will give you an overview of the various pieces, which might come in handy as you start to work with Postfix. Later, after you have more experience with Postfix, you might want to return to this chapter to try to absorb more of the details.

The architecture of Postfix is quite different from that of a monolithic system such as Sendmail, which traditionally uses a single large program for its handling of email messages. Postfix breaks down tasks into separate functions using individual programs that each perform one specific task. Most of these programs are daemons, which are processes that run in the background on your system. The master daemon is started first, and it invokes most other processes, as needed. Postfix daemons that are invoked by the master daemon process their assigned tasks and terminate. They might also terminate after a configured amount of time or after handling a maximum number of requests. The master daemon is resident at all times, and gets its configuration information at startup from both main.cf and master.cf. See Chapter 4 for more information on Postfix configuration files.
