I would like to know which all of you point me as the best training course of CentOS in the world or in the USA. I am a Brazilian and I would like to have this information. I have a good background in GNU/Linux, CentOS and Debian like operating systems, network and general knowledge. I would like to know a deep course about all this subject. I would appreciate any kind of information in advance. Thanks all! -- Edson D. Amaral --------------- Listen to the voices inside of you, they will tell you what is right and what is wrong, they will bring you happiness and peace; if you don't listen to them they can create anxiety, discontentment, and unhappiness. Ouça as vozes dentro de você, elas vão te dizer o que é certo e o que é errado, elas vão lhe trazer felicidade e paz, se você não ouví-las, elas poderão criar ansiedade, insatisfação e infelicidade.
