- In this video, I'm gonna show you
how to install, Packet Tracer on Linux.
In this example, I'm using Ubuntu 20.04,
it's running within a virtual machine on my Mac,
but the process is exactly the same
if you're installing Packet Tracer
on a computer or a laptop.
The installation process
is very simple these days at the time of this recording,
the current release is 7.3.1, much simpler
than in previous releases of Packet Tracer.
Jump to this timestamp if you've already registered
an account with the Cisco NetAcad or Network Academy.
I'm gonna show you the full process in this video,
so I'm gonna show you how to register an account
on the NetAcad website
and then how to download the software and then install it.
So again, jump to this timestamp
if you simply wanna install the software,
you've already got it downloaded as an example.
(upbeat music)
Okay, first thing I'm gonna do is open up Firefox
and I'm gonna search for Packet Tracer.
First hit is the NetAcad website.
You could go directly to this website if you prefer.
Now, if you have an account click Login, Login to,
log into the website.
If you don't have an account,
go to the intro to Packet Tracer course
and click Learn more.
This is a free course that teaches you Packet Tracer,
it's about 10 hours in length.
Go to Sign up today and click English.
Now, Packet Tracer's free software,
they also have this free course that you need to enroll in
to be able to download the software.
So simply register your details
and you'll be able to download the software.
Now you have to put a valid email address in,
so the address that you put in here has to be a valid email
because they're going to send you an activation link.
I'm gonna set this,
Do not send me communications
unless critical to my account.
I'm gonna certify that I'm 13 years or older,
wish I was a lot younger,
but I'm definitely older than 13.
You have to answer a math question
and then click submit to submit your details.
So to create the account,
they pre-populate this with some information.
Now, a lot of people struggle with this,
set company to self
if you don't have a company that you work for,
so if you're just a student, as an example,
set that to self.
Country of residence, I'm gonna set to United Kingdom.
I have to create a password.
So I'll put in my password.
I have to fill in a captcha.
I don't want to receive Cisco promotions
and I'm gonna click Register.
So now I'm gonna log in with my email address
that I registered with and my password.
And notice now we have to put in our verification code.
So in your email, get your verification code and copy that,
and then paste that in and click Verify.
So my email has been verified.
I can continue to my profile,
and again, they want a whole bunch of information.
So you need to specify your gender.
You need to specify state,
how many years you've been in IT for,
do you have a disability,
you need to specify your birth date.
So once you've done that, you can now create an account.
So they get you to do a whole bunch of stuff
to actually get access to the software.
You can now launch a course if you want to,
but I'm not gonna do that.
The Packet Tracer course is very good.
So if you wanna learn how to use Packet Tracer,
then go through that course.
But all I'm gonna do is go to Resources,
Download Packet Tracer.
Now again, at the time of this recording,
the latest release is 7.3.1.
Packet Tracer is available for Windows,
it's available for Linux, it's available for macOS.
In my example, I'm gonna download the Linux version
and I'm gonna save that to my computer.
It's about 173 Meg in size,
so you simply need to wait for that software to download.
What I'm gonna do while I'm waiting for that
is open up a terminal.
So, start a terminal, I'll make this a bit bigger
so it's easier to see what I'm doing.
And what I'll do is check where I am.
I'm in my home directory,
I'm gonna go to my downloads directory,
and you can see that a Packet Tracer deb end file
has been downloaded.
So now this is where you actually install the software,
very simple after all that long winded process
to download it.
So I'm gonna type sudo to use root privileges,
dpkg install, and I'm gonna install Packet Tracer,
so type P and press Tab to auto-complete.
I need to put in my password, which I'm gonna do.
And as you can see, the installation starts,
you have to agree to the license agreement,
so I'm gonna press enter to agree to that.
So say Yes, to accept the license agreement.
And as you can see, Packet Tracer
is now being unpacked and installed.
Now I'm probably gonna get an error here,
so I'm gonna show you how to bypass that error.
And there you go, so notice dependencies are missing.
So to fix that,
I'm gonna type sudo apt install -f
to make sure that all my dependencies are installed,
say yes to install that,
and as you can see,
the dependencies are now being installed.
Now that that's being done,
I'm going to run the installation process again,
so just go through it once more,
and I'm gonna unpack Packet Tracer over itself.
So basically just doing a reinstallation of Packet Tracer.
Now that looks better,
it is complaining about some menu items missing,
but all I'm gonna do is type pack,
press Tab to get to the command Packet Tracer,
hit Enter and notice Packet Tracer now starts.
I'm now asked, would you like to run multi-user
when the application starts?
I don't wanna do that. It's just for me.
So I'm not gonna start multi-user.
You again, have to log in with your user account.
So I'm gonna log in with my email, click Next.
You can continue as a guest,
but that only allows you to save the file three times.
So I don't wanna do that,
I wanna actually run this more than three times.
And there you go,
I've got Packet Tracer installed and running
on my Ubuntu 20.04 computer.
So what I can do as an example is drag a PC to my topology,
I'll zoom in here to make it bigger.
I'll drag a laptop into my topology,
and I'll add a 3650 switch to my topology.
Going to cables, I'll select a cable here
and connect to the PCs to the switch.
Now, if you're not familiar with switches and cables
and so forth, don't worry, I'll cover that in other videos.
Have a look at this playlist, as an example,
if you wanna learn CCNA technologies
and learn about IP addressing cables, et cetera.
One of the things I'll do is go to Options, Preferences,
and I'm gonna show Port a Labels in Logical Workspace,
so I can see my interface names.
Now it's not displaying them very nicely,
but I can see how my devices are connected to each other.
I'm gonna click on the switch
and I'm gonna add a power supply to the switch.
You have to power the switch on
before you can get access to the switch.
So notice we can see that the switch is now booting up.
On this PC, I'll go to Config,
go to FastEthernet0 and give the PC an IP address.
So I've configured my IP address,
I'll go to Desktop Command prompt.
Let's make this a bit bigger.
So I'll go back to Options, Preferences, font for CLI,
rather than using eight,
I'm gonna use 14 and click Apply
to make the CLI fonts bigger.
So back on my PC, as an example, Command prompt,
that's bigger now, easier to see.
So I'm gonna type IP config,
and you can see the IP address of the PC.
It also has a Bluetooth interface,
but we only worrying about Ethernet at the moment.
On the laptop I'll do something similar, go to Config,
FastEthernet0, give it an IP address of 10.1.1.2,
give it a subnet mask of 255.255.255.0,
go to Desktop, Command prompt,
IP config will show me that IP address.
So hopefully the laptop will be able
to ping the PC, which it can,
and hopefully the PC will be able to ping the laptop.
Ping is basically sending a message from one device
to another to check if it's there.
So it's like saying, hello, are you there?
And then the other device replies back saying,
yes, I'm here.
So you can see we sent multiple hellos if you like.
And we got multiple replies from that other device.
So again, on this device,
IP config shows me that the IP address is this
and I'm pinging PC two, or in this case, the laptop,
and I'm getting replies.
Now, once again, if you're not sure about IP addressing,
you don't quite understand what I've done here,
have a look at this playlist where I explain networking
in a lot of detail in my free CCNA course.
But there you go,
I've now got Packet Tracer installed
on an Ubuntu 20.04 computer.
I've downloaded it.
I've installed it.
I've got it running.
And I've built a basic topology in Packet Tracer.
I could exit by typing Exit and I'll save the topology.
So I'll save this as Basic network and click Save.
And there you go.
And what that allows me to do
is if I start Packet Tracer again,
I'll be able to open that topology.
So I'll go to File, Recent files,
you can see that it's saved the Files under
home/David/PT/saves.
So if I wanted to see that home, Packet Tracer,
saves, it saved my topology here.
You might wanna save it somewhere else, so easier to find,
but there you go.
Recent files, I can open up that topology.
The devices are booting.
We can see that the switch interface still
has to transition to green,
that's because it's running a protocol called spanning tree.
Again, don't worry if you're not sure what that is,
I covered that in my CCNA course.
Okay. It's gone green now.
So back on Desktop,
I should be able to ping from PC one to PC two, which I can.
Okay, there you go.
I've shown you how to download,
install and use Packet Tracer,
showing you how to create a basic topology.
In other videos I explain this in a lot more detail,
so have a look at those.
