Cisco Packet Tracer 7.1 is created by Cisco SystemsTM and is now provided for free distribution. Self learners are now able to download Cisco Packet Tracer after registering on Cisco Netacad website. A free Packet Tracer 101 (English), a 1-hour self-paced online course is also offered to every registered (free) student to help them get started with PacketTracer 7.1. So you can register and download from here.
The cisco packettracer 7.1 is available for GNU/Linux under the next requirements:
- nss,linicu and ssl libraries.
- QT5 script-tools, WebKit.
- Cisco NetSpace account. (Mandatory)
- x86_64 family processor (Cisco droped i86 support for Linux)
We need install some libraries as follows:
$ sudo dnf install zlib-devel ncurses-devel gtk2 glibc glibc-devel \\ libpng12 libstdc++ libX11-devel libXrender libXrandr libusb \\ libXtst nss qt qtwebkit qt5-qtmultimedia qt5-qtwebkit
x86_64 (64bits)
Today most people have a x86_64 machine and this time we have three options for resolve the OpenSSL dependency:
1.- Just download the package generated by me and simply trust me (I call this the ugliest method because i don’t provide any warranty):
$ sudo dnf copr enable bt0dotninja/openssl-lib-compat $ sudo dnf install openssl-lib-compat
2.- Compile your own version (I call the “just ugly” method because you can check the source):
First get the code:
$ wget http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/17/Everything/source/SRPMS/o/openssl-1.0.0i-1.fc17.src.rpm $ sudo dnf install @development-tools fedora-packager krb5-devel $ sudo rpm -Uvh openssl-1.0.0i-1.fc17.src.rpm
For the build process we need super user access:
$ su - # cd rpmbuild/SPECS/ # wget http://bt0.ninja/rpm/openssl-lib-compat-1.0.0.spec # rpmbuild -bb openssl-lib-compat-1.0.0.spec # rpm -i ../RPMS/x86_64/openssl-lib-compat-1.0.0i-1.fc27.x86_64.rpm # exit
So many thanks to Yves L’ECUYER owner of http://www.deltaeridani.com, the original spec and the example are all from him.
Cisco Packet Tracer 7.1 will be downloaded from Cisco Networking Academy Portal,
$ tar -xzf PacketTracer71_*_linux.tar.gz && cd PacketTracer71 $ chmod +x install $ sudo ./install
After accept the EULA, the installation begins, we need set the environment variables with the next command:
$ sudo chmod +x /opt/pt/set_ptenv.sh $ sudo /opt/pt/set_ptenv.sh $ sudo chmod +x /opt/pt/set_qtenv.sh $ sudo /opt/pt/set_qtenv.sh
And finally fixing some missing dependencies (Many thanks to Robertpro for this fix )

If for some reason Robertpro stops hosting that libraries, you can download it from here.

With our favorite plain text editor we will edit the file /usr/share/applications/pt7.desktop
as follows:
#!/usr/bin/env xdg-open
[Desktop Entry]
Name=PacketTracer 7.1
Comment=Networking Cisco
GenericName=PacketTracer 7.1
Type=Application
Exec=/opt/pt/packettracer
Icon=pt7
StartupNotify=true
Or as point me the always clever x3mboy, you can just:
$ sudo cp /opt/pt/bin/Cisco-PacketTracer.desktop /usr/share/applications/
Now we will run Cisco Packet Tracer 7.1 from our Desktop:
Awesome! Can’t wait to reinstall my F24 🙂
Hi I did everything that is in the post however I can not get it to start packet Tracer 7.1. This is the error message /lib64/libcrypto.so.1.0.0: no version information available (required by ./PacketTracer7). Search the web but do not manage to correct this error. Can you help me please. Thanks and regards.
Hello Charlie,
I hope you are doing well,
maybe if you can be more specific on your problem i will help you:
what said
ldd /opt/pt/bin/PacketTracer7
?You copy the libicu-* to your home??
Regards
P.D: Sorry for the delay, u know Holidays
Hi, i did all those steps on my fresh Fedora 27, but it just keeps starting but never starts, i found this with ldd:
[root@Fedora23 ~]# ldd /opt/pt/bin/PacketTracer7 |more

libcrypto.so.1.0.0 => /lib64/libcrypto.so.1.0.0 (0x00007fd1f2a62000)
I did all the steps mentioned, so what can i do?
that means than we don’t have some symbol
Hello Cesar,
I hope you are doing well,
maybe if you can be more specific on your problem i will help you, by example , You seen another dependences missing?? You copy the libicu-* to your home??
regards
Hi
Yes , you always get this WARNING message, with the ldd checking, because actually the version information is NOT included in the source of fedora 17 package openssl-1.0.0i
BUT IT IS NOT an ERROR message.
Packet tracer will start any way if there is not other lacking libraries.
Packet tracer 7.1 require extra libraries not required by PacketTracer 7.0:
the /usr/lib64/libicu*.52.*
While Fedora 27 (26 and 25) are providing
the /usr/lib64/libicu*.57.*
So if you do nothing more, than
# ldd /opt/pt/bin/PacketTracer7
will show that PacketTracer7, is linked with three of these:
/usr/lib64/libicu*.57.* libraries.
So once /usr/lib64/libicu*.52.*, are installed
You must execute
# /sbin/ldconfig
so that ldd can include theese new libs as a possible alternative to the current ones /usr/lib64/libicu*.57.*
SO DONT TRY to start PacketTracer-7.1 until you can sea only reference to libicu*.52.*, in the command
# ldd /opt/pt/bin/PacketTracer7
OTHERWISE you’ll get a COREDUMP !!!!!
It is an honor for me that you visit my humble blog, Many thanks for the explanation.
redhat linux Cisco Packettracer 7.1 install package..plz will be mail..if you can..advanced tnx
Thanks alot. It works for me….. again It is very helpul for me…. Thanks dear
many thanks, dont forget to install dependencies from Robertpro !
Thank you sir!
Just tried and instructions above. There is no set_ptenv.sh or set_qtenv.sh scripts included in the packet tracker tar file. The linux tar file was for Ubuntu 14.04. As a result the /opt/pt/packettracer file is empty.
ls -l packettracer
-rwxr-xr-x. 1 root root 0 Jan 28 20:50 packettracer
If I try to run /opt/pt/bin/PacketTracer7 directly I get:
./PacketTracer7
./PacketTracer7: error while loading shared libraries: libicui18n.so.52: cannot open shared object file: No such file or directory
Hi again, that means than you need add the libcui* to the lib path (LD_LIBRARY_PATH environment variable) the empty /opt/pt/packettracer sounds tricky but maybe a failed installation was provoked it. For what architecture is the tar file?
The tar ball was for ubuntu 14.04. That was the only one I noticed for linux. I looked in the tar ball and didn’t see any where that it has the env setup scripts.
Sounds like a catch22, maybe a buggy installation. You tried uninstall and install it again??, the /opt/pt/packettracer not will be empty. Regards
Yeah I actually ran it a couple of times with no success.
That is odd, my /opt/pt/packettracer looks like this:
https://gist.github.com/bt0DotNinja/05b330e82b9eb127aa52654a8d35a4b8
When I put this “sudo rpm -Uvh openssl-1.0.0i-1.fc17.src.rpm”, it show me this line “””” user mockbuild does not exist – using root “””””
and then I cant continue with the others stepts! what can i do????
Sound like a warning and not an error, the shell says something else??
THANK YOU!!!!
Hi Admin
I am glad that you and robertpro, are continuing to support Fedora community users, to help them using PacketTracer under Fedora, from the Package designed by CISCO engineer for Unbuntu.
Just notice that I’m no more owner of http://www.deltaeridani.com.
I stopped to pay for this domain after I chagend my activity in 2017.
But I continue to adapt the PacketTracer when a new release is provided by CISCO
Personally, I prefer to take time to package, anything that I nead as extra package, instead of just copying file.
Because when you want to remove them, it’s allways more difficult than just using :
# dnf remove
On the other hand, I choosed not to install ANYTHING not providing from a “well known source”, on my secured Fedora system with SElinux.
So because PacketTracer 7.1 require extra libs libicu*.52.*.so.* (not required by PacketTracer 7.0)
I packaged icu-lib-compat-52.1 from icu-52.1*.src.rpm from Fedora 21,
on the same model than done for
openssl-lib-compat-1.0.0 from openssl-1.0.0i-1.fc17.src.rpm from Fedora 17
===============
For all the rteaders, just NOTICE than openssl-1.0.0i contain many well known security holes that have been corrected from years now, in recent release of openssl. Unfortunately you have to wait that CISCO product modify the source of packetTracer, in order to use the more recent version of this library !!!
=================
Here is the procedure:
all doner as root
(for example: $ su – root,
in a terminbal of an ordinary user session !)
1°) download the fedora 21 archive icu-52*.src.rpm
# cd /root
# wget http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/21/Everything/source/SRPMS/i/icu-52.1-4.fc21.src.rpm
2°) install it
# rpm -i icu-52.1-4.fc21.src.rpm
3°) go under /root/rpmbuild/SPECS
# cd /root/rpmbuild/SPECS
and duplicate the original icu.spec in a new file: icu-lib-compat-52.1.spec
# cp icu.spec icu-lib-compat-52.1.spec
That we are going to modify just to build a package containing the desired libs,without any file (some share doc for example) conflicting with the current Fedora 27 libicu*.57*.rpm package !!!
4°) now put by copy/paste the following lines (between ==== top and bottom lines excluded of course)
in the file icu-lib-compat-52.1.spec.patch under /root/rpmbuild/SPECS/

5°)apply this pacth
You are always under /root/rpmbuild/SPECS/
# patch icu-lib-compat-52.1.spec icu-lib-compat-52.1.spec.patch
6°) now rebuild the package:
# rpmbuild -bb icu-lib-compat-52.1.spec
this compilation and building require several minutes!
Then when all is done properly you get on the last lines something like:
…
Write : /root/rpmbuild/RPMS/x86_64/icu-52.1-4.fc27.x86_64.rpm

…
Only libicu-compat-52.1-4.fc27.x86_64.rpm is interesting for PacketTracer
(otherwise the other are not installable , because they include many file conflicting by the one , brought by icu*57.rpm package already installed)
So save it in and easy place (in /root, or where you have downloaded packet tracer ???)
And install it with:
# dnf install /root/rpmbuild/RPMS/x86_64/libicu-compat-52.1-4.fc27.x86_64.rpm
7°) in order to use them immediately do not forget to chek the environnement
(doing step by step what packetracer script do)
# PTDIR=/opt/PacketTracer-7.1.0
(or what ever directory you choose to install it)
# export LD_LIBRARY_PATH=$PTDIR/lib
# pushd $PTDIR/bin > /dev/null
# ldd PacketTracer7 | grep libicu

libicudata.so.52 => /lib64/libicudata.so.52 (0x00007f20d505a000)
(if LD_LIBRARY_PATH is not set like this, ldd will show you the reference to
libicu*.so.57, and you will get a core dump at execution time !!)
NOTE
ldd normally complains also about lacking /usr/lib64/libbz2.so.1.0
You can easily make a link
# cd /usr/lib64
# ln -s libbz2.so.1 libbz2.so.1.0
Sorry

Hi:
Thank you for the tutorial, I did a fresh install of Fedora 28 a week ago and tried to follow all of the steps however it didn’t work: I got stuck after I entered “sudo dnf install openssl-lib-compat” it says something like cache for _copr…… repo could not be synchronized or so.
Hi Fabricio, actually the copr repository is not working but you can take the f25 from package http://www.bt0.ninja/openssl-1-0-in-fedora-x86_64-2324-and-25/ (is the same version), I promise update the repo and write a new post for F28.
cheers.
Thank you for the great guide.
I tried it on Fedora 28 and everything works well. I had to build my own openssl RPM because your COPR repository is not yet ready for Fedora 28. But it’s not a big deal.
But something went wrong because after some update I got a segmentation fault with PT 7.2 and 7.1 but 7.0 works well.
I know about the issues in 7.2 (they now including a non compatible library version of qt5-webkit*)but i’m not aware of 7.1 problems, right know i need to update this because is becoming unusable, many thanks for your comment
Hi Lumír,
How did you do that?
I’m on Fedora 28 (64 bit) too. I installed Packet Tracer 7.1.1 but it won’t start if I launch
packettracer
from CLI. If I give./PacketTracer7
(from inside/opt/pt/bin/
) it says ./PacketTracer7: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory. I also tried installing openssl-lib-compat from Admin’s repo but it must be unavailable. Can you tell me how you “build” it yourself? Just download and install the rpm from this website: https://rpmfind.net/linux/rpm2html/search.php?query=openssl ?manually install one of this (all become from the same openssl 1 release) http://www.bt0.ninja/openssl-1-0-in-fedora-x86_64-2324-and-25/
Hello Admin,
I did
sudo rpm -i openssl-1.1.0h-3.fc28.x86_64.rpm
, the OS replied:the package openssl-1:1.1.0h-3.fc28.x86_64 is already installed
. Maybe I should a clean install and start over since other Fedora 28 users have benefited from your instructions above?OMG dude ty really works for my on fedora 28 love u nice job
Still not working for me. I have 3 libicu*52 inside
~/.lib64
but none of them have execution permissions. Under/usr/lib64/
I see the following scripts and their respective soft links:/usr/lib64/libicui18n.so.60.2
/usr/lib64/libicuio.so.60.2
/usr/lib64/libicudata.so.60.2
still, launching PT either by CLI or GUI, doesn’t do anything. I followed all the above listed steps.
I copied those three libicu*52* packages into
/usr/lib64
, gave them execution permissions, then did “ldconfig”. Tried launching/opt/pt/bin/PacketTracer7
, got a new error: “error while loading shared libraries: libQt5Script.so.5: cannot open shared object file: No such file or directory“. Which means libcrypto.so.1.0.0 is somewhat solved! Still I don’t know how to fix this one. I do “ldd -d /opt/pt/bin/PacketTracer7
” and get a long list of missing Shared Obj. among themlibQt5Script.so.5 => not found
libQt5ScriptTools.so.5 => not found"
Any ideas on how to proceed?
Are you running as root? if yes, try as a user.
Hola Enrique, soy Beto , sabes que tu y yo somos amiguitos de la UAM AZC, sucede lo siguiente, ese no es un error de la biblioteca.
para F28 y PT7.2 hay incopatibilidad del QT5 Webkit incluido en con el PT y QT5 en Fedora, puedes revisar si algo te falta con ldd /opt/pt/bin/PacketTracer7
otra cosa, no he estudiado a fondo el caso de F28 + PT7.2, lo que seguro si puedes hechar a andar es PT7.1 o 7 en F28 porque no requiere el QT5 webkit incluido y no corras el /opt/pt/bin/PacketTracer7 sino el script de carga en /opt/pt.
Saludos.
Hello again,
I’ve installed qt5-qtscript, then as super user gave
ldconfig
. Tried launching./PacketTracer7
again. This time, PT seemed to finally launch but then again something went wrong and instead I got the following response:./PacketTracer7: /usr/lib64/libcrypto.so.1.0.0: no version information available (required by ./PacketTracer7)

I’m trying to install Cisco Packet Tracer 7.2 on Fedora 28
Hello there,
I gave up on PT7.1, cleaned the computer of that installation, briefly tried PT7.2 but that was even worse. Finally, got hold of a PT7.0 from http://www.packettracernetwork.com (or I think I did, not sure…). Followed their instruction, this time launching it from CLI worked out of the park! I’ve yet to do exercises and more complicated procedures with it, but at least the GUI starts and that’s a big step forward. So maybe, if anyone’s having trouble, try a previous version of PT on F28, maybe it’ll work fine…
Hi guys!
I’ve just made a Flatpak builder manifest for the Cisco Packet Tracer. It’s the most simple and clean way to run this beast on any Linux (including different versions of Fedora). See at https://github.com/rpallai/flatpak-pt
sorry for the very late response, let me make public your fix, I was trying to solve many lib issues and your solutions is far more simple and elegant
Excellent tutorial. The only one that worked for Fedora 29.
I just suggest you make a note in the item that reads “# rpm -i ../RPMS/x86_64/openssl-lib-compat-1.0.0i-1.fc27.x86_64.rpm”
where you read .fc27 you should change to the current version of the installed system, which in my case is 29.
Thank you for the informations.
