Many of you are tired surfing internet about how to install packettracer in Linux host machine, In this tutorials I simply guide you through  the simplest instruction about installing the packettracer in Linux system, here the Linux host machine that I have considered is  CENTOS-6, but same rule applies for the fedora core as well as for the Redhat Linux,

As, you guys already know packettracer is the cisco devices network simulation software, Packettracer allows us to simulate and test the different networks topology with the CISCO routers and CISCO switches. Without talking much more, let’s jump into our objectives.

To install Packettracer in Linux host, we download the BIN Package of Packettracer from the internet, which can find from this link DOWNLOAD PACKETTRACER, after having this bin package we follow the following steps as shown below


[root@manoj Downloads] # CP PacketTracer533_i386_no_tutorials_installer-rpm.bin /usr/bin

STEP2: Make the Packettracer file executable by issuing the following command

[root@manoj bin] # chmod+x  PacketTracer533_i386_no_tutorials_installer-rpm.bin

STEP3: Installation of Packettracer
To install the packettracer issue the following command in your console, remember that you should be in the bin directory

[root@manoj bin] # PacketTracer533_i386_no_tutorials_installer-rpm.bin

STEP4: Installation Complete
After issuing the above command accept the agreement by typingyes which finally install the packettracer in your LINUX HOST machine, to launch packettracer go to

Hey guys, Do you know what DHCP does ? Why do we need DHCP server and What DHCP provides us ? These are the basic things that we must know before configuring the DHCP server in CISCO router. Let’s dig down in our topic

DHCP: DHCP is the Dynamic host configuration protocol, It works at the application layer of the OSI model. The main function of DHCP is to dynamically assigned the IP address to the HOST machine and to eliminate the IP address conflict between the host machine  in the internetwork. So keep in mind, DHCP has mainly two purposes

  1. Assign IP address Dynamically to host machine
  2. Eliminate the IP address Conflict between the host machine in the network

Besides, above two purposes DHCP also provide many configuration to host machine which are following

  • Assign Default Gateway Address
  • DNS server  address
  • WINS server address
  • Subnet mask of the network where the host machine resides

After knowing some of the basic idea about DHCP server, it’s time to configure the DHCP server in CISCO router, to configure the DHCP Server, we generally consider the GENERIC CISCO router (1841 894 ) any series of router

Let’s go, our prime function is to draw simple network topology and configuring the DHCP server in the cisco router, the topology that we are going to use  is right just below.
