Samba allows UNIX machines to interface with Microsoft networks by supporting SMB and CIFS protocols. It provides file and printer sharing, directory services, and authentication/access control. Samba simulates a Windows domain server and works like a workgroup by default. NIS enables centralized user authentication across networks by using a shared database. All systems can login with the same credentials and password changes are reflected everywhere. It was originally called Yellow Pages by Sun Microsystems. DHCP automatically assigns IP addresses to devices on a network from a defined pool. It issues and manages IP addresses so they are not statically configured on each device. DNS translates human-friendly domain names to IP addresses so computers can communicate. If

3. Introduction Of Samba
Samba is 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 reasons to 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 actually works?
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.

8. Purpose of NIS
•This enables 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 DHCP Server
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 directs the 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
Short for 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.

The primary function of a web server is to deliver web pages
on the request to clients using the Hypertext Transfer Protocol
(HTTP). This means delivery of HTML documents and any
additional content that may be included by a document, such
as images, style sheets and scripts
