Objective:

The objective of this experiment is to learn and run basic windows network commands.

Description of Commands:

ipconfig:

ipconfig is a MS windows console application that displays all current TCP/IP network configuration values and can modify Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.

ipconfig/all:

ipconfig/all is used if the user need detailed information about user’s ip.

arp:

arp (address resolution protocol) Works to show the physical address and IP address translation. displays and modifies the Internet to adapter address translation tables used by the Address in networks and communication management.

finger:

Display information about a user on a specific remote computer(typically a computer running UNIX)If anyone gives a finger a username or an email address and it will try to contact the necessary server and retrieve the username, office, telephone number and other information.

hostname:

It displays the host name portion of the full computer name of the PC.

pathping:

It provides information about network literacy and network loss at intermediate hops between a source and a detination.

It sends multiple Echo request message to each router between a source and a destination over a period of time and then computes as well.

ping:

Verifies IP level connectivity to another TCP/IP computer by sending ICMP Echo request messages.

nbtstat:

Display Net BIOS over TCP/IP protocol statistics, Net BIOS name tables for both the local computer and remote computer.

net:

It is a command that can be used to manage almost every aspect of a network and its settings including managing network shares network print jobs.

netstat:

It is used to display active TCP connection parts on which the pc is listening IP routing tables.

nslookup:

Display information that you can use to diagnose DNA infrastructure.

route : The route command is mainly used to manually configure the routes in the routing table.The route command allows making manual entries into the network routing tables. The route command distinguishes between routes to hosts and routes to networks by interpreting the network address of the destination variable, which can be specified either by symbolic name or numeric address. The route command resolves all symbolic names into addresses, using either the /etc/hosts file or the network name server.

Display and modifies the on time in the local IP routing table.

For example : Add,Change,Delete,Print.

tracert :

Determines the path taken to a destination by sending ICMP (Internet Control Message Protocol) Echo message to the destination.

ftp :

Transfers files to and from a pc running a file transfer protocol.

Network Commend : ipconfig

Fig-1: screenshot of ipconfig

Comments : display the network settings currently assigned and given by a network. This

command can be utilized to verify a network connection as well as to verify our network settings.

Network Commend : ipconfig/all

Fig-2: Screenshot of ipconfig/all

Comments : A detailed information can be found by giving “ipconfig /all” command.

Network Commend : arp

Fig-3 : Screenshot of arp

Comments : Address Resolution Protocolcommand displays and modifies the Internet-to-

adapter address translation tables used by the Address in Networks and communication management. It also displays the current ARP entry for the host specified by the Hostname variable and deletes the host specified by inet_addr.

Network Commend : finger

Fig-4: Screenshot of finger

Comments : Allows a user to find sometimes personal information about a user. This information can include the last time the user logged in, when they read their e-mail, etc... If the user creates a PLAN or other related file the user can also display additional information.

Network Commend : hostname

Fig-5: Screenshot of Hostname

Comments : Displays the host name of the Windows computer currently logged into. Only

users with root user authority can set the host name. The mkdev command and the chdev commands also set the host name permanently.

Network Commend : pathping

Fig-6: Screenshot of Pathping

Comments : This utility enables us to find network latency and network loss.

Network Commend : net

Fig-7: Screenshot of net

Comments : The net command is a Command Prompt command that can be used to

manage almost every aspect of a network and its settings including managing network shares, network print jobs,network statistics, network users etc.

Network Commend : ping

Fig-8: Screenshot of Ping

Comments : Ping allows a user to ping another network IP address. This can help determine if the network card can communicate within the local network or outside network.

Network Commend : nbtstat

Fig-9: Screenshot of nbtstat

Comments : Displays protocol statistics and current TCP/IP connections using NBT.

Network Commend : netstat

Fig-10: Screenshot of netstat

Comments : Used to display the TCP/IP network protocol statistics and information.

Network Commend : nslookup

Fig-11: Screenshot of ns lookup

Comments : Enables a user to do a reverse lookup on an IP address of a domain or host on

a network.

Network Commend : winipcfg

Fig-12: Screenshot of winipcfg

Comments : The winipcfg command allows a user to click here related information such as

the IP address, Subnet Mask, Default Gateway, DHCP Server, WINS Server, etc.

Network Commend : route

Fig-13: Screenshot of Route

Comments : Enables computers to view and modify the computer's route table.

Network Commend : tracert

Fig-14: Screenshot of tracert

Comments: . Using this command we can view a listing of how a network packet travels

through the network and where it may fail or slow down. By using this information we can also determine the computer, router, switch or other network device possibly causing your network issues.

Network Commend : whois

Fig-15: Screenshot of whois

Comments: This command provides information about a domain name much like the

WHOIS on network solutions. In some cases the domain information will be provided from Network Solutions.

Network Commend : ftp

Fig-16: Screenshot of ftp

Discussion:

MS-DOS: Microsoft Disk Operating System is an operating system for x86-based personal computers. It is a non-graphical command line operating system derived from 86-DOS that was created for IBM compatible computers. The command shell, more commonly known as the Windows command line is still used by many users. It is actually a command window of present windows operating system.

CMD: A command-line interface (CLI), also known as command-line user interface, console user interface, and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).

IPv4 address: IPv4 (Internet Protocol Version 4) is the fourth revision of the Internet Protocol (IP) used to identify devices on a network through an addressing system. The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks. IPv4 uses a 32-bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses).

IPv6 address: IPv6 (Internet Protocol Version 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP). IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf

Conclusion:

In this experiment, we have learnt different Windows network commands that are often used for trouble shooting and administering computer network and about their work.This is very helpful to handling network problems and improve our knowledge.
