Ccna

Often after installing PacketTracer 7, we get an error like the one below.

error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

Now let’s see how to fix this error.

After downloading the Packet Tracer, open the terminal in the same directory and extract it from the compressed tar.gz file.

sudo tar -zxvf packetracer7.tar.gz

Let’s enter the folder with the files we opened, if we are in the same directory, let’s run the install bash file without doing anything.

The Cisco Packet Tracer’s latest version or desired version is downloaded from the netcad site or you can download it here without having to sign up. (Download for Cisco Packet Tracer 7.2 64-bit Linux) It’s up to you.

Open the terminal by pressing the keyboard from the Ubuntu Terminal (Ctrl + Alt + t) and extract the tar file:

$ cd ~/Downloads
$ tar xzvf PacketTracer7.2forLinux64bit.tar.gz

packet_tracer_tar

Start the installation from the tar file we opened. And create a directory. Command for the directory.

Cisco packet tracer is a simulation program that provides us a laboratory environment where we can perform many networked experiments and applications without the need of physical network devices and tools.

Now let’s start installing this program.

You can download the application from many web sites on the internet as well as cisco official site can be downloaded after becoming a member.

Cisco Packet Tracer can be downloaded from the links below.

In this article, I will try to explain how to enable the Cisco enable password.

1. Connect the switch to the computer via the console port via a  putty or SecureCRT style program.

2. Unplug the switch in power cable.

3. Power on the switch again and hold down the mode button on the left side of the switch as soon as you power the switch. This opens the switch prompt screen.

Web Redirection and Design Tips

If WCCP protocol is enabled on a router and on an interface, the router looks at a outbound IP packet to see if it is destined for TCP port 80. If so, the packet is redirected to a Cache Engine. For this to work, IP must be configured on the interface connected to the Internet, and on the interface connected to the Cache Engine. The latter must be Ethernet or Fast Ethernet.
