Client Support TCP/IP file sharing with Macintosh clients using Network File System (NFS), and File Transfer Apple File Protocol 3.0. Network Operating System is an operating system that includes special functions for connecting computers and devices into a local-area network (LAN) or Inter-network. Directory Services A directory service is a database of user accounts and other information that network administrators use to control access to shared network resources. Providing basic network administration utilities (such as SNMP, or Simple Network Management Protocol), enabling an administrator to perform tasks involving managing network resources and users. Windows for Work-groups is an example of the program that can function as peer-to-peer network operating systems. Peer-to-peer networks are designed primarily for small to medium local area networks. Updated on 2018-05-09 09:52:31 IST, ComputerNetworkingNotes Some of the features of Network Operating System are to: • It allows multiple computers to connect so that they can share data, files and hardware devices. A typical example of such a system is a set of workstations connected through a local area network (LAN). En France, de nombreux clients faisant du calcul scientifiques furent équipés de ces supercalculateurs : le CNES, Aérospatiale, le CEA, TOTAL, l'armée française, la CGG…. Authentication Successful user authentication in a Windows 2000,2003,2008 computing environment consists of separate processes: interactive logon, which confirms the user's identification to either a domain account or a local computer, and network authentication, which confirms the user's identification to any network service that the user attempts to access.

Interoperability Mac OS X Server uses the Open Source SAMBA to provide Windows users with Server Message Block (SMB) file sharing. A network operating system (NOS) provides services to clients over a network. The LPR component initiates commands such as "print waiting jobs," "receive job," and "send queue state," and the LPD component in the print server responds to them. Monitoring the system and security, so as to provide proper security against viruses, hackers, and data corruption. You create NSS volumes from this storage pool during server installation or later through NWCONFIG. An operating system that provides the connectivity among a number of autonomous computers is called a network operating system. 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. When users connect to a network, they have to be authenticated before they can access network resources. Secure Sockets Layer (SSL) support provides encrypted and authenticated client/server communications. NLMs are programs that run in the background on the server to provide consistent services to the network. • User management and support for logon and logoff, remote access; system management, administration and auditing tools with graphical interfaces.
