The Steps Running GNS3 in Mint PC

There are two ways to put the Cisco simulator program on your Linux system. You can watch our video that shows you everything, or you can read a guide that explains each step. Both ways work well and are simple to understand.

To start the terminal on your Linux Mint computer, do this: press and hold CTRL and Alt at the same time, then press T. This makes the terminal show up. You can do lots of things on your computer with it, like giving commands and doing tasks.
To see if your internet is working right, just type “ping -c 2 www.google.com” and press Enter. This tells your computer to send two bits of data to Google’s website and see if they come back okay.
```
ping -c 2 www.google.com
```
To add it to APT, first, make sure your internet is working well. Then type sudo add-apt-repository ppa:gns3/ppa and press Enter. That’s it!
```
sudo add-apt-repository ppa:gns3/ppa
```
To update the software list on your system, use this: “sudo apt update.” This makes sure you have the newest versions of software to install from the list.
```
sudo apt update
```
To install GNS3 on your Linux Mint, do this in your terminal: type “sudo apt install gns3-server gns3-gui” and hit Enter. When it’s done, it might ask you about how much space it needs on your disk. Just follow things on the screen to finish installing it.
```
sudo apt install gns3-server gns3-gui
```
After you’re done installing it, go to the Setup Wizard window and pick “Run Appliances on my Local Computer.” This starts running the GNS3 virtual network stuff right on your PC.
To make sure your Local Server Configuration is correct, check that the Host Binding setting says Localhost. This ensures that your server can only be reached from your PC, not from outside networks.
Make sure to check the “Local Server Status” section to see if your connection to the server on your PC is working. This lets you make sure the connection is set up right.
Please go to the “Summary” section from its GUI and check the settings for Localhost to make sure they’re set up right.
After finishing the Setup Wizard, add a Cisco Router IOS by clicking “Edit” and then “Preferences.” This brings you to a page where you can set up and change your router settings as you need.
To make a new IOS router template in Dynamips, go to the Dynamips/IOS Routers section and click New. This opens a page called New IOS Router Template, where you can change the settings and set up your new Router.
To put the IOS image in the New IOS Router Template, click the Browse button and pick the image you want from the file explorer.
It’s best to give your device a unique name once you add the Router IOS To keep your network clear. This name should make it easy to tell your device apart from others on the network. Also, make sure to mention the platform your device is on to make sure everything works smoothly.
When you’re changing your computer’s settings, think about the Memory setting. Usually, it’s set to a specific value. But if your computer is strong, you should put it higher for better performance. Just remember, if you put it too high, your computer might get slower. So, find the best balance for you.
To make your Router work better, it’s a good idea to add either a gigabit ethernet or serial interface to the Network Adapters settings. This helps data move faster and makes the connection better.
It’s wise to set an Idle-PC value that works well with your system to stop your computer from working too hard because of the Router. This makes sure the Router uses only a little of your computer’s power, which could slow it down or make it freeze.
Once you find the correct Idle-PC value for your IOS, it’s a good idea to close the IOS wizard and the Template window. This stops any more changes to the settings, so your setup stays the same. Then you can keep working without any unexpected problems.
To start setting up your device, you can begin by adding the Router you just put into it to your current setup.
