Brief information about Network Information System
Network Information System (NIS) is a client-server directory service protocol for distributing system configuration data across networks. It is primarily used to enable a single user login across an entire system network. Originally part of the UNIX operating system, it facilitates sharing critical data among networked computers, ensuring consistency across the network.
The History of the Origin of Network Information System and the First Mention of It
The Network Information System was first introduced by Sun Microsystems in 1985 as part of its Network Computing System (NCS). It was known originally as Yellow Pages but was later renamed to NIS to avoid confusion with the commercial telephone directory. The main objective was to centralize administration of UNIX systems. It later became a standard feature in UNIX and Linux distributions.
Detailed Information about Network Information System: Expanding the Topic
NIS was designed to make network administration more manageable by maintaining shared configuration files. It stores information like usernames, passwords, hostnames, group information, and other network details in a central database, distributing this information across the network.
Key Components
- Domain: A set of machines sharing the same data.
- Server: Hosts the NIS database and handles queries.
- Client: Queries the server to access shared information.
The Internal Structure of the Network Information System: How It Works
Server Operations
- The server stores data in maps.
- It responds to client requests with the corresponding information.
Client Operations
- The client requests data by querying the server.
- The server responds with the requested information.
Interaction
- Clients query servers using Remote Procedure Call (RPC).
Analysis of the Key Features of Network Information System
- Centralization: Allows centralized management of network information.
- Scalability: Easily scales across large networks.
- Security: Implementable with security measures, but has known vulnerabilities.
