- 3. Introduction Of Samba Sambais a suite of open-source applications that support the Server Message Block (SMB) and Common Internet File System (CIFS) protocols used by Microsoft operating Systems. This allows the Samba applications to interface into Microsoft networks to provide inter operability across normally different networking systems. In other words, Samba enabled UNIX machine can masquerade as a server on your Microsoft network and offer the services. The package required for samba server is “samba”.
- 4. Three prime reasonsto use samba server File and Printer Sharing Services:- Using the Server Message Block (SMB) protocol to facilitate the sharing of files, folders, volumes, and the sharing of printers through out the network. Directory Services:- Sharing vital information about the computers and users of the network with such technologies as the Light weight Directory Access Protocol (LDAP) and Microsoft Active Directory®. Authentication and Access:- Establishing the identity of a computer or user of the network and determining the information the computer or user is authorized to access using such principles and technologies as file permissions, group policies, and the Kerberos authentication service
- 5. How samba actuallyworks? Samba server simulates a window domain server; how ever as seen it actually works just as a workgroup .As a matter off act, it is defaulted to a workgroup.

Purpose of NIS •Thisenables centralized user logins across networks. •The centralized database allows users to login and change passwords in one location and have the changes reflected across all involved systems. Background Information NIS was originally developed by Sun Microsystems under the name Yellow Pages. However, we are not allowed to use that trademarked name.

- 12. Introduction of DHCPServer Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (i.e., a scope) configured for a given network. DHCP assigns an IP address when a system is started, for example: •A user turns on a computer with a DHCP client. •The client computer sends a broadcast request (called a DISCOVER or DHCPDISCOVER), looking for a DHCP server to answer.
- 13. •The router directsthe DISCOVER packet to the correct DHCP server. •The server receives the DISCOVER packet. Based on availability and usage policies set on the server, the server determines an appropriate address (if any) to give to the client. The server then temporarily reserves that address for the client and sends back to the client an OFFER (or DHCPOFFER) packet, with that address information. The server also configures the client's DNS servers, WINS servers, NTP servers, and sometimes other services as well. •The client sends a REQUEST (or DHCPREQUEST) packet, letting the server know that it intends to use the address. •The server sends an ACK (or DHCPACK) packet, confirming that the client has a been given a lease on the address for a server- specified period of time.

- 16. Introduction of DNS Shortfor Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
