Hello everybody,

I usually use docker or systemd-nspawn for do container stuff, both are so good, but this time we will use systemd-nspawn because it can generate a x86 environment on x86_64 architectures. This feature is important to run some programs packet on dot deb format and/or  are available only in  x86 architecture.

Now install and setup systemd- nspawn, we will create a Debian GNU/Linux based container:

$ sudo dnf -y install systemd-container debootstrap
$ mkdir debian
$ sudo debootstrap --arch=i386 testing ./debian

Some time later… configure debian container root password,

$ sudo systemd-nspawn --directory=./debian passwd

<username> will be replaced with the user name as you wish

$ sudo systemd-nspawn --directory=./debian useradd <username>
$ sudo systemd-nspawn -D ./debian apt-get update
$ sudo systemd-nspawn -D ./debian apt-get install default-jre ssh iceweasel

Booting container,logging as root and install iceweasel. Note: you need to replace ~/Downloads with the directory path where you downloaded your “program of interest”.

$ sudo systemd-nspawn -bD ./debian --bind ~/Downloads:/mnt:rbind 

Now we are inside the ontainer:

test@debian~$ export DISPLAY=:0 && iceweasel

To exit use shutdown the container as a normal debian system or kill holding Ctrl and rapidly press ] three times

As Cultural breviary, iceweasel is now firefox again, see the old notice here.

Right now I’m working in the first edition of my podcast ”El Andariego” about a wide range of topics like GNU/Linux, DevOps, Linux User Group of UAM-AZC, VoIP, Big Data, etc.

This idea is possible by the following software:

  • Fedora 24
  • Audacity 2.1.2
  • LibreOffice (scripts)

  • Lenovo ThinkPad T440s
  • Mico Desktop microphone (from China)
  • Marshall Headphones Model: Major (Also from China)

  • coffee (from “la tamalera” of the street corner)
  • Pockys (from Thailand)

Hello everybody,

The cisco packettracer 6.3 is available for GNU/Linux under the next requirements:

  • x86 libraries.
  • nss and ssl libraries.
  • QT4 script-tools, WebKit  and QT3 backward support.
  • (Optional ) Cisco NetSpace account.

We need install x86 libraries (32 bits) if our system is x86_64 (64bits) as follows:

$ sudo dnf install zlib-devel.i686 ncurses-devel.i686 gtk2.i686 glibc.i686 glibc-devel.i686 \\
 libstdc++.i686 libX11-devel.i686 libXrender.i686 libXrandr.i686 libusb.i686 libXtst.i686 nss.i686 \\
 qt.i686 qtwebkit.i686
$ wget  http://www.deltaeridani.com/openssl-lib-compat-1.0.0i-1.fc24.i686.rpm
$ sudo rpm -Uvh openssl-lib-compat-1.0.0i-1.fc24.i686.rpm

Cisco Packet Tracer 6.3 will be downloaded from Cisco Networking Academy Portal or in another places on internet, only ask to google for “PacketTracer63_linux.tar.gz”,

$ tar -xzf PacketTracer63_linux.tar.gz && cd PacketTracer63
$ chmod +x install
$ sudo ./install

After accept the EULA, the installation begins, we need set the environment variables with the next command:

$ sudo /opt/pt/set_ptenv.sh

At this point packettracer is ready to use but another useful thing to do is create a desktop Cisco Packet Tracer icon to launch it, first download the icon:

$ wget http://upload.wikimedia.org/wikipedia/en/d/dc/Cisco_Packet_Tracer_Icon.png
$ sudo mv Cisco_Packet_Tracer_Icon.png /usr/share/icons/

With our favorite plain text editor we will create the file /usr/share/applications/packettracer.desktop as follows:

[Desktop Entry]
Encoding=UTF-8
Name= PacketTracer 6.3
Comment=Networking Cisco
GenericName=Cisco PacketTracer 6
Type=Application
Exec=/opt/pt/packettracer
Icon=/usr/share/icons/Cisco_Packet_Tracer_Icon.png
Categories=Education;
StartupNotify=true

Now we will run Cisco Packet Tracer 6.3 from our Desktop:

I am Alberto Rodríguez Sánchez, Computer Engineer with SysAdmin and DevOps Voip experience but Data Scientist dreams and in the middle of Master degree in optimization.

This mix of skills, knowledge and studies really don’t make any sense but is funny and enjoyable.

This blog show my (mixed) interest (except my deep fascination in female beauty) with focus in GNU/Linux, Voip and Data Science, possibly some optimization topics.

Many thanks for reading and please follow in my social networks. cheers!!!

Bienvenido amable lector, gracias por acompañarme en este mi segundo proyecto de blog, el primero tuvo lugar en la increíble y extinta mononeurona.org , tristemente no he podido recuperar ninguno de los post de aquellos ayeres, aunque también mis intereses han cambiado un poco, he viajado otro poco y he trabajado mucho, entonces este nueva etapa de blogging sera diferente a la anterior en muchos sentidos, las entradas personales, de poesía, de recetas y políticas serán en mi lengua madre, las entradas técnicas serán en ingles preferentemente y si el tiempo no apremia, ofreceré a ustedes la versión en español.

Inicio también un modesto proyecto de podcasting, la intensión es ser complemento a las entradas y estar dirigido a publico diferente.

saludos amigos
