Cet OS très puissant n'a pourtant pas été accompagné d'un hardware compétitif par rapport aux machines Unix de chez Sun, HP, IBM ou face aux crayettes qui ont presque toutes disparues en 2009. Secure Shell (SSH) provides encryption and authentication for secure remote administration. Un article de Wikipédia, l'encyclopédie libre. Because the security provider maintains a network-wide list of user accounts and passwords, each client computer does not have to store a list of accounts.
