How to Assign IP Address Linux in RHEL 5 & RHEL 6

In this Tutorial I am going to show how to assign Permanent IP Address in Linux. Specially RedHat and CentOS 5 Linux.

 First you have to do is to Log on as root user and go to the Directory  /etc/sysconfig/network-scripts/ to view all available devices.

    # cd /etc/sysconfig/network-scripts/

You need to edit following files:

    /etc/sysconfig/network-scripts/ifcfg-eth0 ( First Ethernet card configuration file)
    /etc/sysconfig/network-scripts/ifcfg-eth1  ( Second Ethernet card configuration file)

To edit/create first NIC file, type command:

    # vim ifcfg-eth0

Append/modify as follows:


Save and close the file. (:wq!)

After that, configure the default gateway (router IP) and hostname in /etc/sysconfig/network file:

    # vim /etc/sysconfig/network

Append/modify configuration as follows:


Save and close the file(:wq!). Restart networking by enter following command:

    # /etc/init.d/network restart

Make sure you have correct DNS server defined in /etc/resolv.conf file:

    # vi /etc/resolv.conf

Setup DNS Server as follows:


Save and close the file(:wq!). Now you can check(ping) the gateway/other hosts:

     # ping          (check network connection)
    #ping www.google.com    (check Internet connection )

IF You want to assign temporary ip address then Log on as root user and run the below command.
#ifconfig eth0:0 netmask
#ifconfig eth0:1 netmask

How to Configure NFS Server on Windows 7

Usually we configure NFS Server on Linux/Unix Machine for File sharing in Network between Unix Machines,But here in this tutorial we learn how to configure a Windows 7 machine as NFS Server.
I have used third party software named hanewin nfs package to install nfs package on windows and configure NFS Server on Windows7 machine.

If you want to configure NFS Server on Linux you can easily configure NFS server.

Usually people know that NFS Server is configured on Linux Machine only for sharing files with Linux clients. But that's half truth. In real world today we can easily configure NFS on windows Machine also. 

If you want to configure NFS Server with NIS Server and Autofs on Red Hat Enterprise Linux you can watch this video.

First we need to configure NIS SERVER.We set NIS DOMAIN NAME and then we will configure NFS Server and after that we will configure Autofs Server for automation process.Not forget to configure Firewall and Selinux otherwise your configuration will not work.

Practical Implementation of NIS NFS and Autofs Server on Red Hat Enterprise Linux.

You can submit this project in your Engineering Major Project.This is very helpful for computer science students.

How to setup and configure hostname in Red Hat Enterprise Linux 7

This tutorial is completely about hostname setup and hostname configuration in Red Hat Enterprise Linux 7. so if you are new to RHEL7  and you want to setup or configure hostname in your RHEL7 Machine then this tutorial is for you.Watch the below video carefully and you will very easily learn to configure hostname in RHEL7 Linux.

Why we set hostname in Linux machine?

Assigning a hostname to a PC or HOST is just like giving a name to an IP.
HOST means all the computers in a network.Each computer is a host in a network and the ip address assigned to that host machine or that computer is host address and the name given to that particular pc or computer or host is hostname.

Difference between HOST ADDRESS & HOSTNAME

IP assigned to the host pc or any pc in a network is known as host address and the name assigned to any pc or host in a network is known as hostname.

Why it necessary to set HOSTNAME in Linux?

see it's not easy for anyone to remember ip address so we need a name for each ip in our local network to differentiate or to identify specific machine easily and to make our task easy.

Apache Web server configuration in RHEL 7

Step 3: Using firewall allow http service to get accessed.

#firewall-cmd  --permanent  -add-service=http
#firewall-cmd  --permanent  -add-service=https
#firewall-cmd  --reload

Step 4:Restart and enable Apache Service in RHEL7

#systemctl restart httpd
#systemctl enable httpd

Step 5:go inside /var/www/html folder and create index.html or index.php file according to your requirement.You can see in video.

Step 6:repeat step 4

Step 7:If you want to access your site with name you can set hostname to your RHEL machine.

Network Security Related terminology you must know

Here in this article i am including the important terminology we need to know if we are working as a system engineer ,network engineer,system administrator whether Linux or Windows admin didn't matter.Here i will provide you the complete list of terms we need to know in networking or system admin field.Here in this tutorial i have discussed about various topics like pap,chap,asynchronous,,Tokens,throughput,RADIUS SERVER,TACACS,AAA,Data owner,subject,object,baseline,policies,procedures,standard,guideline,ARO,SLE etc

Risk = Threat * Vulnerability

If we consider the topi regarding IT sector then Risk consists of these two important thing Threat and Vulnerability.where there is no Threat there is no risk.If there is Vulnerability in your system or Network and there is also threat of attack then risk is multiple effect of vulnerability.

ALE = Annualized Loss Expectancy

This is an important terminology and every IT company have almost a separate department to handle ALE.

AV = Asset Value

If you have a little knowledge off commerce field you can easily understand what asset value is.In short you understand it is a type of business valuation.


EF means Exposure Factor - % of value lost


SLE stand for Single Loss Expectancy, the cost of a single loss.


ARO stands for  Annual Rate of Occurrence (number of losses)


 Total Cost of Ownership combining upfront costs and annual costs of maintenance


Policies are high-level management directives that don't go into specifics.


Procedures are step-by-step guides for accomplishing a task


describes specific use of technology


recommendations (discretionary)


 uniform ways of implementing a safeguard

Data Owner 

management employee responsible for ensuring protection of specific data


Authentication, Authorization, and Accountability

Least privilege

 says minimum amount required to do.
 privileges are defined in every level whether it os operating system based or networking based.
operating system have several users created on privilege based. Administrator user have   highest privilege than other and Guest user have least privileges than others.In Linux root have highest privilege.
In network deices like Routers and switches also have different privilege levels.

Need to know is more granular


 active entity on a data system


As we are here talking about computer and network system.In IT Sector or in computer field or networking department by saying OBJECT we mean passive data within the system.


Discretionary mean full control of objects they have access to


mandatory means system-enforced based on labels


role based, non-discretionary

Task-based = another non-discretionary method


 Uses UDP 1812 and 1813. AAA system.
RADIUS request and response data is carried in
8-bit AVPs (Attritbute Value Pairs)


RADIUS' successor with more accountability and a 32-bit AVP field.


Tacacs is used for authentication and autheriation.
It is a centralized access control system that uses UDP port 49 and may use TCP


PAP stands for password authentication protocol and CHAP stands for challenged handshake authentication protocol.both used PPP connection.

You can READ:PAP Configuration Tutorial on cisco Router.

You can READ: CHAP Configuration on Cisco router.

PAP is plaintext so not so secure, while CHAP uses three way handshake. so chap is  better than pap.

Objects have labels, and you have to have clearance to see them.

Synchronous Dynamic Tokens 

While talking about Synchronous Dynamic Tokens one must know that it't refresh every 60 seconds. Use time or counters to synchronize a code with the AS.

Asynchronous Tokens 

 It is little different from Synchronous Dynamic Tokens and is not synchronized with central server. Challenge-response.


 As we all know it is the most important point for any company institute or organiation and that is throughput. It is actually the biometric system response time.

arp spoofing and cache poison attack demonstartion project for computer science students(B.Tech/BCA/MCA/M.tech)

ARP Spoofing and cache poison attack demonstration Project and Future Scope.This is subject of ethical hacking and cyber security.So anyone including computer science students interested in ethical hacking field or cyber security then this tutorial is for you.In this article i will guide you to create an ethical hacking project whose name is "ARP SPOOFING and CACHE POISON ATTACK".

Before i start explaining this project I love to inform you that you must have basic idea of networking and Linux before working on this project.

What actually ARP SPOOFING is?

ARP spoofing is a type of security attack in which the attacker spoofs the ARP reply packet sent to a destination address with its own mac-address.


 The project aims to demonstrate the concept of ARP spoofing, where the ARP cache of Windows XP is poisoned with the attacker mac-address for a specific system on the network.

Hardware and Software Requirement for this Project:

1.Three PC (Ubuntu and Windows XP, Windows7/8)

Either you need three different Computers one having windows xp installed ,second pc have Windows7 or Windows 8 Installed and third PC have Ubuntu Linux installed.
I suggest you to use a virtualization software like Oracle VirtualBox or Vmware Workstation.
And then install all these three operating system inside them and configure virtual box networking between them so that they can communicate with each other.

2.Scapy and Python (Free download )

Install Scapy and Python tool.remember these are free tools and are easily available on internet.


If you are using three different PC then you need a SWITCH.If you are using Virtualization software it will be better to user your home wi-fi network.

4.Network cables
If you are using wi-fi network you don't need any network cables.But if you are using switch then you need three straight cable to connect computers with switch so that all pc can communicate with each other.

Project Report Contents:

1. Project Scope

2. Hardware and Software.

3. Lab topology with IP network design

4. Software installation

5. Steps to execute with code and script.

6. Verification with Screenshots.
