Project Report

What is networking? A Networking is simply a collection of computers or other hardware devices that are connected together, either physically or logically, using special hardware and software, to allow them to exchange information and cooperate. Networking is the term that describes the processes involved in designing, implementing, upgrading, managing and otherwise working with networks and network technologies

.Types of networkingThe types of network are categorized on the basis of the number of systems or devices that are under the networked area.

Different types of network are:

Local area network

A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node. Current wired LANs are most likely to be based on Ethernet technology

Campus area network

A campus network is a computer network made up of an interconnection of local area networks (LANs) within a limited geographical area. The networking equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc.) are almost entirely owned (by the campus tenant / owner: an enterprise, university, government etc.).

Metropolitan area network

A metropolitan area network (MAN) is a network that connects two or more local area networks or campus area networks together but does not extend beyond the boundaries

GTT CHD Page 5

Project Report

Wide area network

A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and air waves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies

Network topologyIt is a geometric representation of your network there are many types of network topology the selection of network topology depend of area of network, cost of network and its also depend of the redundancy. There are many types of network topology

BUS TOPOLOGY

In local area networks where bus topology is used, each machine is connected to a single cable. Each computer or server is connected to the single bus cable through some kind of connector. A terminator is required at each end of the bus cable to prevent the signal from bouncing back and forth on the bus cable. A signal from the source travels in both directions to all machines connected on the bus cable until it finds the MAC address or IP address on the network that is the intended recipient. If the machine address does not match the intended address for the data, the machine ignores the data. Alternatively, if the data does match the machine address, the data is accepted. Since the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other topologies. However, the low cost of implementing the technology is offset by the high cost of managing the network. Additionally, since only one cable is utilized, it can be the single point of failure. If the network cable breaks, the entire network will be down.

GTT CHD Page 6

Project Report

STAR TOPOLOGY

Many home networks use the star topology. A star network features a central connection point called a "hub" that may be a hub, switch or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet. Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.)

RING TOPOLOGY

The ring topology is a type of computer network configuration where each network computer and device is connected to each other forming a large circle (or similar shape). Each packet is sent around the ring until it reaches its final destination. Today, the ring topology is seldom used. Below is a visual example of a simple computer setup on a network using a ring topology

GTT CHD Page 7

Project Report

MESH TOPOLOGY

Mesh Network is a network where all the nodes are connected to each other and is a complete network. In a Mesh Network every node is connected to other nodes on the network through hops. Some are connected through single hops and some may be connected with more than one hope. While the data is traveling on the Mesh Network it is automatically configured to reach the destination by taking the shortest route which means the least number of hops. Data travels by hopping from one node to another and then reaches the destination node in a Mesh Topology Network.

GTT CHD Page 8

Project Report

TREE TOPOLOGY

Among all the Network Topologies we can derive that the Tree Topology is a combination of the bus and the Star Topology. The tree like structure allows you to have many servers on the network and you can branch out the network in many ways. This is particularly helpful for colleges, universities and schools so that each of the branches can identify the relevant systems in their own network and yet connect to the big network in some way.

GTT CHD Page 9

Project Report

Network devices

Computer networking devices are also called network equipment, Intermediate Systems (IS) or Interworking Unit (IWU). Units there are the many network devices.

LAN card

It network interface card, network adapter, network interface controller (NIC), or LAN adapter is a computer hardware component designed to allow computers to communicate over a computer network each lan card has its own Mac Address and this mac address is 12 digits and 48 bits address its first 6 digits are assign by the IEEE and last 6 digits are assign by the manufacturing company at the time of manufacture the lan card it’s also called logical address

HUB

Hub Stands of hierarchical universal bus. An Ethernet hub, active hub, network hub, repeater hub or hub is a device for connecting multiple twisted pair or fiber optic Ethernet devices together and making them act as a single network segment. Hubs work at the physical layer (layer 1) of the OSI model. The device is a form of multiport repeater. Repeater hubs also participate in collision detection, forwarding a jam signal to all ports if it detects a collision.

There are two types of Hub

Active Hub

Passive Hub

Active Hub: In this types of hub we need to give power it pass the data as well as amplify the signal also

Passive hub: In this types of hub we don’t need to give power it only pass the data it does, t amplify the signal.

FEATURES OF HUB

Its work on layer one It doe,t have memory to save the Mac address It always broadcast the signal It’s also called multiport repeater

GTT CHD Page 10

Project Report

It is use with h small network

SWITCH

It is a network device which is use for the point to point connection. Its also called intelligent devices because it transmit the data on Mac address based it has small memory where its create Mac table for point to point transmission there are two types of switch

Manageable switch: In this type of switch we can create V- Lan (virtual Lan) and then member of same vlan can only communicate with each other.

Non manageable switch: in this type of switch we can’t create the V-Lan all the switch port can communicate with each others.

Features of Switch

It’s also called intelligent devices Its work on Layer 2 It has small memory to save the Mac address To communicate the two or more computer first it broadcast and then it transmit the data

point to point In manageable switch we can create vlan and then members of same vlan can

communicate with each others.

GTT CHD Page 11

Project Report

Switch states

Disable states Blocking state Listening state Forwarding state

Disable State: By default all the switch ports are in the disable state Blocking state : In blocking state all the ports can’t send and receive traffic and can’t

learn Mac-address they can only send BPDU message and select the root bridge Listening state In this root ports and designated ports and selected and no traffic will be

send and received even no Mac address can be learn Learning state: In this state while the port doesn’t forwards the frame it does learn

source Mac address from the frame received. Forwarding state: In this state switch ports send and receive traffic

ROUTER: A router is a device that interconnects two or more computer networks, and

selectively interchanges packets of data between them. Each data packet contains address information that a router can use to determine if the source and destination are on the same network, or if the data packet must be transferred from one network to another. Where multiple routers are used in a large collection of interconnected networks, the routers exchange information about target system addresses, so that each router can build up a table showing the preferred paths between any two systems on the interconnected networks. And its works on network layer. To communicate the two more routers we use routing protocol to update the routing tables these routing protocols are

MODEM: Short for modulator-demodulator. A modem is a device or program that enables a

computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

It is not so important, here, to know how modems do work but it is essential to make the difference between the different types of computer modem.

Internal computer modems: Some computers have an internal modem which can be a built-in modem or a PC card modem. For the PC card modem, a PCI slot or even sometimes an ISA slot is required; depending on the available interface your

motherboard uses to receive the modem. Internal computers modems are used with Dial- Up Internet connection through a couple of RJ-11 connection. Also called copper telephone lines, the RJ-11 allows computer to receive and send data as explained above. Internal computers modems are usually 56K modems which mean that the modem is able to receive 56 Kbits/s (56 kilobits or 56000 bits per second) of data. This kind of data transmission is called downstream transmission , came from a provider and transmitted over telephone lines. Commonly it is the standard bandwidth with telephones lines.

External modems : It is the second term we have to consider from different types of computer modem. An External modem can be used to the same purpose and in the same

GTT CHD Page 13

Project Report

conditions as internal computer modem . However external modem is a small box that uses other kind of interfaces to be connected to the computer.It could be a serial modem , named thus because it uses the serial port to connect to the computer. Usually installed on the back of the computer, the serial port is an easy-to-install option for the external modem. The same small box, on the other hand, can be an USB modem which normally uses USB port usually placed on the back or in front of the computer. First of all external modem can be a Dial-Up modem but more expensive than the internal. As well as another type of external modem you may consider two important types of modem: cable modem and DSL modem if you need high-speed internet services. All ISPs usually supply a specialized modem named digital modem in the broadband package. It’s important to notice that cablemodem has to connect to an Ethernet card, placed on the computer PCI slot to provide a broadband internet connection to the user. This is true if you opt to use Ethernet connection. However you won't need it if your option goes to use an USB connection.

Cable MODEM . The cable modem uses a coaxial cable television lines to provide a greater bandwidth than the dial-up comuter modem. An extremely fast access to the Web is providing by the cable modem with downstream transmission up to 38 Mbits/s and an upstream transmission up to 1 Mbits/s. Unfortunately this transmission rate fluctuates with the number of users because of the shared bandwidth on which the cable technology is based.

DSL MODEM . DSL ( Digital Subscriber Line ) modem is exclusively used for connections from a telephone switching office to the user. This technology, available and frequently usable, split up into two main categories.

ADSL or ASYMETRIC DIGITAL SUBCRIBER LINE is used in North America and supports from 1.5 Mbits/s up to 9 Mbits/s of downstream transmission rate and up to 3 Mbits/s of upstream transmission rate.

SDSL. SDSL or Symetric Digital Subcriber Line is used in Europe and has the same data rates for downstream and upstream transmission which is 128 Kbits/s.

FIREWALL

A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices which is configured to permit or deny computer applications based upon a set of rules and other criteria.

Firewalls can be implemented in either hardware or software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especiallyintranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.

GTT CHD Page 14

Project Report

There are several types of firewall techniques:

Packet filter: Packet filtering inspects each packet passing through the network and accepts or rejects it based on user-defined rules. Although difficult to configure, it is fairly effective and mostly transparent to its users. It is susceptible toIP spoofing.

Application gateway: Applies security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose performance degradation.

Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.

Proxy server: Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.

NETWORK CABLES:

Networking Cables are used to connect one network device to other or to connect two or more computers to share printer, scanner etc.Cables are used depending on the network's topology, protocol and size. Three types of cables are used to design the network.

TWISTED PAIR CABLE: Twisted pair cable is a type of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources It is an inexpensive

GTT CHD Page 15

Project Report

medium to connect the system in local network segment. There are two types of Twisted Pair Cables.

UTP (Unshielded Twisted Pair) STP (Shielded Twisted Pair)

UTP (Unshielded Twisted Pair): UTP cable is a medium that is composed of pairs of wires. UTP cable is used in a variety of networks. Each of the eight individual copper wires in UTP cable is covered by an insulating material. In addition, the wires in each pair are twisted around each other. UTP cable often is installed using a Registered Jack 45 (RJ-45) connector, especially for Ethernets. The following summarizes the features of UTP cable:

Speed and throughput—10 to 1000 Mbps Average cost per node—Least expensive

Media and connector size—Small

Maximum cable length—100 m (short)

Different category of UTP cables are:

7 Cat 6 1000 Mbps 600 MHz

UTP CABLE

GTT CHD Page 17

Project Report

STP (Shielded Twisted Pair):- Shielded twisted-pair (STP) cable combines the techniques of shielding, cancellation, and wire twisting. Each pair of wires is wrapped in a metallic foil. The four pairs of wires then are wrapped in an overall metallic braid or foil, usually 150-ohm cable. As specified for use in Ethernet network installations, STP reduces electrical noise both within the cable (pair-to-pair coupling, or crosstalk) and from outside the cable (EMI and RFI). STP usually is installed with STP data connector, which is created especially for the STP cable. However, STP cabling also can use the same RJ connectors that UTP uses.

The following summarizes the features of STP cable:

Speed and throughput—10 to 100 Mbps Average cost per node—Moderately expensive

Media and connector size—Medium to large

Maximum cable length—100 m (short)

Different categories of STP Cables are:

150 Ohm Shielded Twisted Pair Cable Cat 5E

An Ethernet cable is a type of Ethernet cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router, such as directly connecting two personal computers via their network adapters. There are different slandered to create the network cable.

Straight cable Cross Cable

Roll Over Cable

Straight Cable

You usually use straight cable to connect different type of devices. This type of cable will be used most of the time and can be used to:

GTT CHD Page 19

Project Report

1) Connect a computer to a switch/hub's normal port.2) Connect a computer to a cable/DSL modem's LAN port. 3) Connect a router's WAN port to a cable/DSL modem's LAN port.4) Connect a router's LAN port to a switch/hub's uplink port. (Normally used for expanding network) 5) Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using normal port.

Crossover Cable

Sometimes you will use crossover cable, it's usually used to connect same type of devices. A crossover cable can be used to:

1) Connect 2 computers directly.2) Connect a router's LAN port to a switch/hub's normal port. (Normally used for expanding network)3) Connect 2 switches/hubs by using normal port in both switches/hubs.

GTT CHD Page 20

Project Report

In you need to check how crossover cable looks like, both side (side A and side B) of cable have wire arrangement with following different color.

In case you need to make a crossover cable yourself! You can use crimper to do it.

Rollover cables: it like other cabling types got their name from how they are wired. Rollover cables essentially have one end of the cable wired exactly opposite from the other. This essentially “rolls over” the wires- but why would we need to do such a thing? Rollover cables, also called Yost cables, usually connect a device to a router or switch’s console port. This allows a programmer to make a connection to the router or switch, and program it as needed. A visual example can be seen below:

COAXIAL CABLE

Coaxial cabling has a single copper conductor at its center. A plastic layer provides insulation between the center conductor and a braided metal shield. The metal shield helps to block any outside interference from

Coaxial cable

Although coaxial cabling is difficult to install, it is highly resistant to signal interference. In addition, it can support greater cable lengths between network devices than twisted pair cable. The two types of coaxial

Thin coaxial cable is also referred to as thinnet. 10Base2 refers to the specifications for thin coaxial cable carrying Ethernet signals. The 2 refers to the approximate maximum segment length being 200 meters. In actual fact the maximum segment length is 185 meters. Thin coaxial cable has been popular in

Thick coaxial cable is also referred to as thicknet. 10Base5 refers to the specifications for thick coaxial cable carrying Ethernet signals. The 5 refers to the maximum segment length being 500 meters. Thick coaxial cable has an extra protective plastic cover that helps keep moisture away from the center conductor. This makes thick coaxial a great choice when running longer lengths in a linear bus network

GTT CHD Page 22

Project Report

Why Use Coaxial Cable?

Coaxial cable has many advantages over twisted-pair cable but also a few disadvantages. It has a large frequency range which allows it to carry multiple signals, making it ideal for carrying many cable television broadcasts. Each channel also has greater bandwidth that allows for high definition video. The shielding reduces crosstalk and other interference, allowing for greater cable lengths between amplifiers. However, coaxial cable is more expensive to install, and it uses a network topology that is prone to congestion.

FIBER OPTIC CABLE

Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials (See fig. 5). It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference. It has also made it the standard for connecting networks between

Fiber optic cable has the ability to transmit signals over much longer distances than coaxial and twisted pair. It also has the capability to carry information at vastly greater speeds. This capacity broadens communication possibilities to include services such as video conferencing and interactive services. The cost of fiber optic cabling is comparable to copper cabling; however, it is

The center core of fiber cables is made from glass or plastic fibers. A plastic coating then cushions the fiber center, and kevlar fibers help to strengthen the cables and prevent breakage. The outer insulating jacket made of teflon or PVC.

Fiber optic cable

There are two common types of fiber cables -- single mode and multimode. Multimode cable has a larger diameter; however, both cables provide high bandwidth at high speeds. Single mode can provide more distance, but it is more expensive.

WIRLESS LAN

Wireless LANs use high frequency radio signals, infrared light beams, or lasers to communicate between the workstations and the file server or hubs. Each workstation and file server on a wireless network has some sort of transceiver/antenna to send and receive the data. Information is relayed between transceivers as if they were physically connected. For longer distance, wireless communications can also take place through cellular telephone technology, microwave transmission, or by satellite.

Wireless networks are great for allowing laptop computers or remote computers to connect to the LAN. Wireless networks are also beneficial in older buildings where it may be difficult or impossible to install cables.

The two most common types of infrared communications used in schools are line-of-sight and scattered broadcast. Line-of-sight communication means that there must be an unblocked direct line between the workstation and the transceiver

Wireless standards and speeds

The Wi-Fi Alliance is a global, non-profit organization that helps to ensure standards and interoperability for wireless networks, and wireless networks are often referred to as WiFi (Wireless Fidelity). The original Wi-Fi standard (IEEE 802.11) was adopted in 1997. Since then many variations have emerged (and will continue to emerge). Wi-Fi networks use the Ethernet protocol.

Standard Max Speed Typical Range

802.11a 54 Mbps 150 feet

802.11b 11 Mbps 300 feet

802.11g 54 Mbps 300 feet

GTT CHD Page 25

Advantages of wireless networks:

Mobility - With a laptop computer or mobile device, access can be available throughout a school, at the mall, on an airplane, etc. More an more businesses are also offering free WiFi access.

Fast setup - If your computer has a wireless adapter, locating a wireless network can be as simple as clicking "Connect to a Network" -- in some cases, you will connect automatically to networks within range.

Cost - Setting up a wireless network can be much more cost effective than buying and installing cables.

Expandability - Adding new computers to a wireless network is as easy as turning the computer on (as long as you do not exceed the maximum number of devices).

PATCH PANEL

The patch panel connects the network's computers to each other and to the outside lines that enable the LAN to connect to the Internet or another WAN. Connections are made with patch cords. The patch panel allows circuits to be arranged and rearranged by plugging and unplugging the patch cords.

OSI MODEL The O.S.I. (Open System Interconnection) model is a way of sub-dividing a System into smaller parts (called layers) from the point of view of communications. A layer is a collection of conceptually similar functions that provide services to the layer above it and receives services from the layer below it. On each layer an instance provides services to the instances at the layer above and requests service from the layer below. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of the path. Conceptually two instances at one layer are connected by a horizontal protocol connection on that layer.

Project Report

The functions of the seven layers of the OSI model are:

Layer Seven of the OSI Model

The Application Layer of the OSI model is responsible for providing end-user services, such as file transfers, electronic messaging, e-mail, virtual terminal access, and network management. This is the layer with which the user interacts.

Layer Six of the OSI Model

The Presentation Layer of the OSI model is responsible for defining the syntax which two network hosts use to communicate. Encryption and compression should be Presentation Layer functions.

Layer Five of the OSI Model

The Session Layer of the OSI model is responsible for establishing process-to-process communications between networked hosts.

Layer Four of the OSI Model

The Transport Layer of the OSI model is responsible for delivering messages between networked hosts. The Transport Layer should be responsible for fragmentation and reassembly.

Layer Three of the OSI Model

The Network Layer of the OSI model is responsible for establishing paths for data transfer through the network. Routers operate at the Network Layer.

Layer Two of the OSI Model

The Data Link Layer of the OSI model is responsible for communications between adjacent network nodes. Hubs and switches operate at the Data Link Layer.

Layer One of the OSI Model

GTT CHD Page 28

Project Report

The Physical Layer of the OSI model is responsible for bit-level transmission between network nodes. The Physical Layer defines items such as: connector types, cable types, voltages, and pin-outs.

IP ADDRESS

Ip address is 32 bits numeric number which is use to assign to your lan card to uniquely identify your computer in the network.

Since networks vary in size, there are four different address formats or classes to consider when applying to NIC for a network number:

Class A addresses are for large networks with many devices. Class B addresses are for medium-sized networks.

Class C addresses are for small networks (fewer than 256 devices).

Class D addresses are multicast addresses.

Class E address are Reserved for future use, or Research and Development Purposes.

Class Address Range SupportsClass A

1.0.0.1 to 126.255.255.254 Supports 16 million hosts on each of 127 networks.

Class B

128.1.0.1 to 191.255.255.254

Supports 65,000 hosts on each of 16,000 networks.

Class C

192.0.1.1 to 223.255.254.254

Supports 254 hosts on each of 2 million networks.

Class D

What is Subnet Mask?

Ip address is divided into two parts its first part is NID (Network Identification) and second part is HID (Host Identification) and subnet mask is use to identify the which part of your ip address is NID and which part of your ip address is HID.

Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0

Private address

A computer on the Internet is identified by its IP address. In order to avoid address

conflicts, IP addresses are publicly registered with the Network Information Centre

(NIC). Computers on private TCP/IP LANs however do not need public addresses, since

they do not need to be accessed by the public. For this reason, the NIC has reserved

certain addresses that will never be registered publicly. These are known as private IP

addresses, and are found in the following ranges:

From 10.0.0.0 to 10.255.255.255

From 172.16.0.0 to 172.31.255.255

From 192.168.0.0 to 192.168.255.255

APIPA ADDRESS

A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server or on a network if a DHCP server is temporarily down for maintenance. With this feature, a Windows computer can assign itself an Internet Protocol (IP) address in the event that a DHCP server is not available or does not exist on the network.

The Internet Assigned Numbers Authority (IANA) has reserved 169.254.0.0-169.254.255.255 for Automatic Private IP Addressing.

What is CIDR?

CIDR (Classless Interdomain Routing) that allows internet service provider to reduce the wasting of ip address by assigning a subnet to a company instead of the entire network. It also reduce the size of internet routing tables in the router.CIDR allows routing protocols to summarize multiple networks in a single route. With CIDR ip address and their subnet mask are written as four

GTT CHD Page 30

Project Report

octets, separated by period and followed by a forward slash that represent the number of subnet mask. Example -172.16.1.0/24 is a Class B subnetted address and 24 shows the number of network bit in this address and the subnet mask would be 255.255.255.0.We write the CIDR value according to the number of bits available for the network part. For example-

255.0.0.0-netwoek bit is 8 so CIDR value is /8

255.128.0.0-network bit is 9so CIDR value is /9

255.240.0.0-network bit is 12 so CIDR value is /12

255.255.240.0-network bit is 20 so CIDR value is /20.

255.255.255.252-network bit is 30 so CIDR value is /30

When we see subnet mask of slash notation (CIDR), we can know the following thing-

/28

Means network bits are 28-11111111 11111111 11111111 11110000

NETWORK PROTOCOLS

Protocol is a set of rules or language that computer use to communicate with each other if two computers want communicate with each other they must have the same protocols Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received

Some protocols also support message acknowledgement and data compression designed for reliable and/or high-performance network communication. Hundreds of different computer network protocols have been developed each designed for specific purposes and environments.

Internet Protocols

The Internet Protocol family contains a set of related (and among the most widely used network protocols. Besides Internet Protocol (IP) itself, higher-level protocols like TCP, UDP, HTTP, and FTP all integrate with IP to provide additional capabilities. Similarly, lower-level Internet Protocols like ARP and ICMP also co-exist with IP. These higher level protocols interact more closely with applications like Web browsers while lower-level protocols interact with network adapters and other computer hardware.

Routing Protocols

Routing protocols are special-purpose protocols designed specifically for use by network routers on the Internet. Common routing protocols include EIGRP, OSPF and BGP.

Different types of protocols are:

GTT CHD Page 32

Project Report

TCP/IP It is a combination of two protocol tcp is a different and ip is a different tcp divided the message into small segments and ip check the ip address so that data reach at their proper destinations.

ARP - Address Resolution Protocol enables the packaging of IP data into Ethernet packages. It is the system and messaging protocol that is used to find the Ethernet (hardware) address from a specific IP number. Without this protocol, the Ethernet package could not be generated from the IP package, because the Ethernet address could not be determined.

RARP - Reverse address resolution protocol is used to allow a computer without a local permanent data storage media to determine its IP address from its Ethernet address.

TCP - A reliable connection oriented protocol used to control the management of application level services between computers. It is used for transport by some applications.

UDP - An unreliable connection less protocol used to control the management of application level services between computers. It is used for transport by some applications which must provide their own reliability.

IGMP - Internet Group Management Protocol used to support multicasting. IGMP messages are used by multicast routers to track group memberships on each of its networks.

FTP - File Transfer Protocol allows file transfer between two computers with login required.

TFTP - Trivial File Transfer Protocol allows file transfer between two computers with no login required. It is limited, and is intended for diskless stations.

HTTP - Hypertext Transfer Protocol is used to transport HTML pages from web servers to web browsers. The protocol used to communicate between web servers and web browser software clients.

DHCP - Dynamic host configuration protocol is a method of assigning and controlling the IP addresses of computers on a given network. It is a server based service that automatically assigns IP numbers when a computer boots. This way the IP address of a computer does not need to be assigned manually. This makes changing networks easier to manage. DHCP can perform all the functions of BOOTP.

BOOTP - Bootstrap protocol is used to assign an IP address to diskless computers and tell it what server and file to load which will provide it with an operating system.

GTT CHD Page 33

Project Report

RIP - Routing Information Protocol is used to dynamically update router tables on WANs or the internet. A distance-vector algorithm is used to calculate the best route for a packet.

OSPF - Open Shortest Path First dynamic routing protocol. A link state protocol rather than a distance vector protocol. It tests the status of its link to each of its neighbors and sends the acquired information to them.

POP3 - Post Office Protocol version 3 is used by clients to access an internet mail server to get mail. It is not a transport layer protocol.

IMAP4 - Internet Mail Access Protocol version 4 is the replacement for POP3.

Telnet is used to remotely open a session on another computer. It relies on TCP for transport

SLIP - Serial Line Internet Protocol. This protocol places data packets into data frames in preparation for transport across network hardware media. This protocol is used for sending data across serial lines.

PPP - Point to Point Protocol is a form of serial line data encapsulation that is an improvement over SLIP which provides serial bi-directional communication. It is much like SLIP but can support AppleTalk, IPX, TCP/IP, and NetBEUI along with TCP/IP which is supported by SLIP

NFS - Network File System is a protocol that allows UNIX and Linux systems remotely mount each other's file systems

SMTP - Simple Mail Transfer Protocol is used to transport mail. Simple Mail Transport Protocol is used on the internet; it is not a transport layer protocol but is an application layer protocol

DNS - It is a vital part of operating system without dns we have to know the ip address of every system with that we are communicating

NETBIOS – it work same as dns but NetBIOS use with local network and it doesn’t need to be configuring before using.

NETWORK SHARING

In computing, a shared resource or network share is a device or piece of information on a computer that can be remotely accessed from another computer, typically via a local area network or an enterprise Intranet, as if it were a resource in the local machine. There are two types of sharing.

GTT CHD Page 43

Project Report

Online sharing Offline sharing

Online sharing: in online sharing user can access the share folder for how long he is connected with the network.Offline sharing: in offline sharing user can access the share folder even if we discounted from the network

How to share the folder or drive

Right click on folder Properties Sharing Enter the share name Assign permissions by default permission is read when we share the folder or

drive in Window xp and latest OS.

WHAT IS MAP NETWORK DRIVE

It is an easy method to access the share folders in the network. Windows XP supports several different methods for mapping a network drive. A network drive is a file folder located on a remote computer that has been configured for sharing over a LAN. These instructions explain the process to map a shared network drive using Windows Explorer.

1. Open Windows Explorer or My Computer from the Windows Start Menu.

2. From the Tools menu, click Map Network Drive…. A new Map Network Drive window opens.

3. In the Map Network Drive window, choose an available drive letter from the dropdown list located next to the "Drive:" option. Any drives already mapped will have a shared folder name displayed inside the dropdown list, next to the drive letter.

4. Type the name of the folder to map. This name must follow UNC. Alternatively, click the Browse… button to find the correct folder by browsing available network shares.

5. Click the "Reconnect at login" checkbox if this network drive should be mapped permanently. Otherwise, these drives will un-map when the user logs out of this computer.

6. If the remote computer that contains the shared folder requires a different username and password to log in, click the "different user name" hyperlink to enter this information.

Windows Server 2008

Windows Server 2008 is one of Microsoft Windows' server line of operating systems. Released to manufacturing on February 4, 2008, and officially released on February 27, 2008, it is the successor to Windows Server 2003, released nearly five years earlier. A second release, named Windows Server 2008 R2, was released to manufacturing on July 22, 2009

Features of window server 2008

Windows Server 2008 is built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality. Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista such as the rewritten networking stack (native IPv6, native wireless, speed and security improvements); improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and ASLR; improved Windows Firewall with secure default configuration; .NET Framework 3.0 technologies

Server Core

Windows Server 2008 includes a variation of installation called Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed. All configuration and maintenance is done entirely through command line interface windows, or by

GTT CHD Page 56

Project Report

connecting to the machine remotely using Microsoft Management Console. However, Notepad and some control panel applets, such as Regional Settings, are available.

Server Core does not include the .NET Framework, Internet Explorer, Windows Power Shell or many other features not related to core server features. A Server Core machine can be configured for several basic roles: Domain controller/Active Directory Domain Services, ADLDS (ADAM), DNS Server, DHCP Server, file server, print server, Windows Media Server, IIS 7 web server and Hyper-V virtual server. Server Core can also be used to create a cluster with high availability using Failover Clustering or Network Load Balancing.

Active Directory roles

Active Directory roles are expanded with identity, certificate, and rights management services. Active Directory, until Windows Server 2003, allowed network administrators to centrally manage connected computers, to set policies for groups of users, and to centrally deploy new applications to multiple computers. This role of Active Directory is being renamed as Active Directory Domain Services (ADDS).[9] A number of other additional services are being introduced, including Active Directory Federation Services (ADFS), Active Directory Lightweight Directory Services (AD LDS), (formerly Active Directory Application Mode, or ADAM), Active Directory Certificate Services (ADCS), and Active Directory Rights Management Services (ADRMS). Identity and certificate services allow administrators to manage user accounts and the digital certificates that allow them to access certain services and systems.

Windows PowerShell

Windows Server 2008 is the first Windows operating system to ship with Windows PowerShell, Microsoft's new extensible command line shell and task-based scripting technology.[11] PowerShell is based on object-oriented programming and version 2.0 of the Microsoft .NET Framework and includes more than 120 system administration utilities, consistent syntax and naming conventions, and built-in capabilities to work with common management data such as the Windows Registry, certificate store, or Windows Management Instrumentation. PowerShell's scripting language was specifically designed for IT administration, and can be used in place of cmd.exe and Windows Script Host.

Self-healing NTFS

In Windows versions prior to Windows Vista, if the operating system detected corruption in the file system of an NTFS volume, it marked the volume "dirty"; to correct errors on the volume, it had to be taken offline. With self-healing NTFS, an NTFS worker thread is spawned in the

GTT CHD Page 57

Project Report

background which performs a localized fix-up of damaged data structures, with only the corrupted files/folders remaining unavailable without locking out the entire volume and needing the server to be taken down. The operating system now features S.M.A.R.T. detection techniques to help determine when a hard disk may fail.

Server Manager

Server Manager is a new roles-based management tool for Windows Server 2008[15]. It is a combination of Manage Your Server and Security Configuration Wizard from Windows Server 2003. Server Manager is an improvement of the Configure my server dialog that launches by default on Windows Server 2003 machines. However, rather than serve only as a starting point to configuring new roles, Server Manager gathers together all of the operations users would want to

conduct on the server, such as, getting a remote deployment method set up, adding more server roles etc., and provides a consolidated, portal-like view about the status of each role.

How to install windows server 2008

Installing Windows Server 2008 is pretty straightforward and is very much like installing Windows Vista,

Note: Windows Server 2008 can also be installed as a Server Core installation, which is a cut-down version of Windows without the Windows Explorer GUI. Because you don’t have the Windows Explorer to provide the GUI interface that you are used to, you configure everything through the command line interface or remotely using a Microsoft Management Console (MMC). The Server Core can be used for dedicated machines with basic roles such as Domain controller/Active Directory Domain Services, DNS Server, DHCP Server, file server, print server, Windows Media Server, IIS 7 web server and Windows Server Virtualization virtual server

To use Windows Server 2008 you need to meet the following hardware requirements:

Component RequirementProcessor • Minimum: 1GHz (x86 processor) or 1.4GHz (x64 processor) • Recommended:

2GHz or faster Note: An Intel Itanium 2 processor is required for Windows Server 2008 for Itanium-based Systems

Memory • Minimum: 512MB RAM • Recommended: 2GB RAM or greater • Maximum (32-bit systems): 4GB (Standard) or 64GB (Enterprise and Datacenter) • Maximum (64-bit systems): 32GB (Standard) or 2TB (Enterprise, Datacenter and Itanium-based Systems)

Available Disk Space

• Minimum: 10GB • Recommended: 40GB or greater Note: Computers with more than 16GB of RAM will require more disk space for paging, hibernation, and dump files

9. In the "Which type of installation do you want?" window, click the only available option – Custom (Advanced).

10. In the "Where do you want to install Windows?", if you're installing the server on a regular IDE hard disk, click to select the first disk, usually Disk 0, and click Next.

GTT CHD Page 64

Project Report

If you're installing on a hard disk that's connected to a SCSI controller, click Load Driver and insert the media provided by the controller's manufacturer.

11. The installation now begins, and you can go and have lunch. Copying the setup files from the DVD to the hard drive only takes about one minute. However, extracting and uncompressing the files takes a good deal longer. After 20 minutes, the operating system is installed. The exact time it takes to install server core depends upon your hardware specifications. Faster disks will perform much faster installs… Windows Server 2008 takes up approximately 10 GB of hard drive space.

The installation process will reboot your computer, so, if in step #10 you inserted a floppy disk (either real or virtual), make sure you remove it before going to lunch, as you'll find the server hanged without the ability to boot (you can bypass this by configuring the server to boot from a CD/DVD and then from the hard disk in the booting order on the server's BIOS)

12. Then the server reboots you'll be prompted with the new Windows Server 2008 type of login screen. Press CTRL+ALT+DEL to log in.

13. Click on Other User.

14. The default Administrator is blank, so just type Administrator and press Enter.

15. You will be prompted to change the user's password. You have no choice but to press Ok.

16. In the password changing dialog box, leave the default password blank (duh, read step #15…), and enter a new, complex, at-least-7-characters-long new password twice. A password like "topsecret" is not valid (it's not complex), but one like "T0pSecreT!" sure is. Make sure you remember it.

17. Someone thought it would be cool to nag you once more, so now you'll be prompted to accept the fact that the password had been changed. Press Ok.

18. Finally, the desktop appears and that's it, you're logged on and can begin working. You will be greeted by an assistant for the initial server configuration, and after performing some initial configuration tasks, you will be able to start working.

DYNAMIC HOST CONFIGURATION PROTOCOL (DHCP)

Dynamic Host Configuration Protocol (DHCP) is a communications enabling network administrators manage centrally and automate the assignment of IP addresses in a network. In an IP network, each device connecting to the Internet needs a unique IP address. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.

DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It's especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses.

DHCP operations fall into four basic phases: IP discovery, IP lease offer, IP request, and IP lease acknowledgement. It’s called DORA Process

DORA PROCESS

DISCOVER: When a client is configured with the ip setting to obtain Ip address automatically. Then the client will search for DHCP server and the UDP Broadcast to the server about the DHCP discover

OFFER: DHCP Server will offers a scope of ip address available in the pool.

REQUEST: In response to the offer, the Client will requests for an ip address.

ACKNOWLEDGE: In response to the request, server will responds with all Ip address, Mask, Gty, Dns and wins info along with the acknowledgment packet.

Anyone has some more suggestion. You can update it.

DHCP Scopes

Scope - A range of IP addresses that the DHCP server can assign to clients that are on one subnet.

Super scope - A range of IP addresses that span several subnets. The DHCP server can assign these addresses to clients that are on several subnets.

Multicast scope - A range of class D addresses from 224.0.0.0 to 239.255.255.255 that can be assigned to computers when they ask for them. A multicast group is assigned to one IP address. Multicasting can be used to send messages to a group of computers at the same time with only one copy of the message.

Client Reservation

Client Reservation is used to be sure a computer gets the same IP address all the time. Therefore since DHCP IP address assignments use MAC addresses to control assignments, the following are required for client reservation:

MAC (hardware) address IP address

DHCP Database Options

Backup - Includes scopes and all options. The database is automatically backed up to:

\WINNTROOT\System32\Dhcp\Backup\Jet

The backup interval is stored in the registry at:

HKey_Local_Machine\System\CurrentControlSet\Services\DhcpServer\Parameters\BackupInterval

A duplicate registry key is in the \WINNTROOT\System32\Dhcp\Backup\dhcpcfg file

Restore - The backup is loaded if the DHCP database is determined to be corrupt by the system at initialization. A backup can be forced by copying the backup directory contents into the DHCP directory.

Compact - The database is normally compacted, but for NT3.51 or earlier, the JETPACK.EXE utility can be used to compact the database to improve performance. If the size is 30MB, it should be compacted. This utility is run from the \WINNTROOT\System32\Dhcp directory. The DHCP service should be stopped before running this utility.

Database files:

DCHP.MDB - The main database DHCP.TMP - Temporary DHCP storage.

JET*.LOG - Transaction logs used to recover data.

SYSTEM.MDB - USed to track the structure of the DHCP database.

Tools

IPConfig options:

/all - Shows much configuration information from local hostname, IP address, subnet mask to DHCP server and WINS server address and lease dates. It will display an IP address of 0.0.0.0 and DHVP address of 255.255.255.255 if the DHCP attempt was unsuccessful.

/renew

/release

How to configure the dhcp step by step
