libpng12.so.0 and libcrypto.so.1.0.0 error on ubuntu/kali and debian while using PacketTracer



There is an error while starting Cisco Packet Tracer in latest Debian derived operating systems like Ubuntu, Kali etc.

First problem is libpng error:

 ./PacketTracer7: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory.


Other error is libcrypto.so.1.0.0: no version information available


solution:


In this post we are going to solve both above errors.
I am using Ubuntu 19.04 but it works on other Linux OS with same problem.

libpng12 error is caused because Packet Tracer can't find libpng12 library in /lib/x86 folder

You can try to install it with apt-get install libpng12-0 but there is a high chance it will throw an error while trying to install. So follow these steps to fulfill libpng12 requirement manually.


First we have to get libpng12 so follow below steps:
 --> Download libpng12-0 from official website according to your system architecture.
      --> link for ubuntu 64bit version:https://packages.ubuntu.com/xenial/amd64/libpng12-0/download

-->extract .deb file in a folder using following command
    --> sudo -x deb_file_name.deb ~/test
       -->replace "deb_file_name.deb" with the name of your downloaded file and "~/test" with desired folder to extract libpng12 deb package 

 





so there are two solutions

1. Directly placing libpng in Packet Tracer directory
2. Creating Softlink




1-->Packet Tracer is installed in /opt/pt directory by default. So I am assuming you also have installed in /opt/pt but can can change commands according to you installation directory

Copy libpng12.so.0 from extracted folder test/lib/x86_64-linux-gnu/ ("test" according to above command) to bin folder of packet tracer. /opt/pt/bin by default.

command:sudo cp ~/test/lib/x86_64-linux-gnu/libpng12.so.0 /opt/pt/bin


2-->creating soft link of libpng12.so.0 in /lib/x86_64-linux-gnu directory

command:sudo ln -s ~/test/lib/x86_64-linux-gnu/libpng12.so.0 /lib/x86_64-linux-gnu/libpng12.so.0

note: If you create soft link it will be removed as soon as you delete 
/test/lib/x86_64-linux-gnu/libpng12.so.0 and it will also be removed if you try to install libpng12 with apt-get install or with dpkg -i.

So I suggest using no. 1 method.







after this some users may face "libcrypto.so.1.0.0: no version information available" error also it is caused because of unavailibly of libssl package

you can solve it just by installing libssl1.0.0 package
--> sudo apt-get install libssl1.0.0 
install libssl-dev also just to be sure
--> sudo apt-get install libssl-dev

1 : Introduction : Android Rat From Scratch

      Hello everyone In this series we will create a Remote Access Trojan(RAT) for android. Both server and client are apk. There are many RAT available like Droidjack, Spynote. Metasploit is also excellent framework for remote access. They work very well but there are some problems:     Device Portability : As these tools can only be used on Windows/Linux so we can’t take our PC or laptop everywhere like our android phone.     Static IP : We need a static IP to maintain access to victim’s device. We can use noip but it can only provide us static address for 30 day.     Port Forwarding : Some ISPs block port forwarding. So we need to be connected to a router to forward port.     AV/Google detection : These apps can be easily recognized as threat by Google because these are very popular tools. These problems will be automatically solved in our RAT. Read next...

previos:  2 : Features of android RAT : Android Rat From Scratch next: 4 : Detailed overview and workflow of this series : Android Rat From Scratch  Hello everyone So you have seen some features of our RAT now we will start creating it. Now before starting creating RAT we must create a normal hello world! apk. We are going to use Android Studio to create our apk files. We are using android studio 2.3.3 version but you can use any version you want.(after 2.3.3) here is the official link for latest android studio developer.android.com/studio/ If you have  worked on Android Studio before then it will be very easy for you and if you have not worked with Android Studio then see some tutorials online on using Android Studio and create some basic apps. We will not teach you android development or using android studio. We will only focus on creating  RAT. I recommend spending a few hours on tutorialspoint.com/android/ before moving further. ...
