I want to install GNS3 on my Linux Mint. The website gave me two files to download


I downloaded them both but I don't know the difference and I have never installed anything on Linux Mint.

These are just different ways of compressing the file. The contents will be the same so you should just be able to use tar to extract the contents of either one.

So something like the following:

tar -xzvf GNS3-0.8.3-src.tar.gz

My guess is that there will be a README in the uncompressed code that will give you instructions.

I corrected your answer. tar does not take an extraction location as an argument. To specify where you want the files extracted to, e.g. foo/, use tar -xvf GNS3-0.8.3-src.tar.gz -C foo/. – terdon Aug 30 '12 at 16:11

Although jmreicha's solution will work if you want to install from source, the easiest way to install most programs on any Debian derived system (including Ubuntu and Linux Mint) is to use apt-get. For example, this command will install GNS3:

$ sudo  apt-get install gns3 

For a graphical way, try Synaptic Package Manager or Software Manager from the Menu->Administration.

Instructions for installing the latest GNS3 from source on Ubuntu distributions.

GNS3 is a graphical network simulator. In order to emulate Cisco network devices, the dynamips emulator will need to be installed as well.

  1. Install the following recommended packages:

    sudo apt-get install qt4-dev-tools

    sudo apt-get install pyqt4-dev-tools

  2. Before downloading the files for GNS, create the following two directories:

    sudo mkdir /opt/GNS3

    sudo mkdir /opt/GNS3/Dynamips

  3. Go to the GNS download page for the latest version (The latest version is 0.8.4-RC2) or download directly from here.

  4. Go to the dynamips download page:

  5. Go to the folder where you downloaded the two files.

    • Unpack the GNS files:
    • sudo tar -jxf GNS3-0.8.4-RC2-src.tar.bz2

    • Move the files to the /opt/GNS3 directory:

      • sudo mv GNS3-0.8.2-src/* /opt/GNS3
    • Move the dynamips binary to the /opt/GNS3/Dynamips directory:

      • sudo mv dynamips-0.2.8-RC2-x86.bin /opt/GNS3/Dynamips
    • Change the permissions on the Dynamips binary to make it executable:

      • sudo chmod +x /opt/GNS3/Dynamips/dynamips-0.2.8-RC2-x86.bin
  6. Start GNS3
    • sudo python gns3

I would recommend taking a look at the following video from the GNS3 team for further instructions and decent explanation of validating the rest of your GNS3 installation.
