This is a long post, but most of it is file contents. Keep reading!
GNS3 appliance files are descriptions of virtual machines used in network simulations. The appliance files have suffixes of .gns3a and are included with the GNS3 download. You can update the files and create new ones. The goal of this article is to walk through the process of working with appliance files and contributing them back to the community.
On a personal note, submitting a new GNS3 appliance was the first time I contributed to an open-source project. I’m still learning, but a few years ago I knew nothing. Jeremy Grossman, with GNS3, was patient and helped me understand the process of using Git. Contributing - even in this minor way - was a real high for me and I’d love for you to be able to share that feeling and contribute to this and other projects. GNS3a was my “gateway drug” into being a contributor and not just a consumer of open source.
One of the files I’ve contributed is the Security Onion appliance. Security Onion is a Linux distribution that focuses on security tools. Below is the current version (9/1/20) of the GNS3A file. Before we create a new appliance, let’s update this one.
Do you have your own Indian family daily life story to share? The kitchen table is always open.
In a bustling lane of Old Delhi, three generations of the Sharma family share a four-story ancestral home. Ramesh (68) starts his day reading the newspaper on the balcony while his grandsons ask him for help with Hindi vocabulary.
The sun rises over India not as a solitary event, but as a chorus. Before the first golden ray touches the windowpane, the chai is already boiling. In an Indian household, the day does not begin with an alarm clock, but with the clinking of steel vessels, the low hum of prayers, and the soft padding of bare feet on marble floors.
Food is an expression of love. A mother or parent will often insist on serving family members hot, fresh flatbreads ( rotis ) straight from the stove to their plates, refusing to sit down until everyone else is fully fed. Constant Celebration: The Festive Calendar
The day starts in the courtyard. The men head out to inspect the agricultural fields, while the women milk the cows and light the earthen stove ( Chulha ) for breakfast.
The Rhythm of the Modern Indian Household The Indian family lifestyle is a dynamic blend of deep-rooted cultural traditions and rapid modern evolution. Across towns and megacities, daily life revolves around shared rituals, collective decision-making, and an underlying philosophy that places family at the center of the universe. To truly understand this lifestyle, one must look past the statistics and step into the sensory, chaotic, and affectionate reality of their everyday stories. The Morning Symphony: Chaos and Connection
: Vegetable sellers ( sabziwalas ) push wooden carts down narrow lanes, calling out their fresh produce. Ragpickers, knife-sharpeners, and fruit vendors create a familiar acoustic tapestry.
: Frozen meals are rare; vegetables are bought fresh daily, and wheat is often ground at local mills.
The Indian family lifestyle and daily life stories are a testament to the country's rich cultural diversity and tradition. The joint family system, daily routines, and observance of festivals and rituals all contribute to a unique and vibrant family setup that is quintessentially Indian. While challenges and changes are a part of modern life, the Indian family remains a strong and resilient institution, continuing to evolve and adapt to the changing needs of its members. As a result, the stories of daily life in Indian families continue to inspire, educate, and entertain, providing a glimpse into the warm, vibrant, and diverse world of Indian culture.
Indian family lifestyle is a dynamic blend of ancient traditions and modern realities. At its core lies the philosophy of collectivism, where the community and family outweigh the individual. To truly understand daily life in India, one must look past the statistics and step into the living rooms, kitchens, and courtyards where everyday stories unfold.
Another essential aspect of Indian family life is education. Education is highly valued in Indian culture, and families often make significant sacrifices to ensure that their children receive a good education. Many Indian families believe that education is the key to success and a better future.
The younger generation is asserting its need for personal space, mental health awareness, and career choices outside of traditional engineering or medicine.
Dinner is arguably the most sacred hour of the day. It is rarely a solitary event or a meal eaten out of boxes in front of individual screens.

Most of this is pretty straight forward. The structure looks like:
A descriptive section
Next is the Qemu section that describes how the VM environment should be constructed. This is straightforward as well. Console types are VNC or telnet. You may have to try different ethernet adapters to see what works, but I recommend starting with the Intel e1000 because this model is supported by most VMs. Using a para-virtualized adapter may give better performance, so you may also want to try vmxnet3. Most architectures will be 64bit and RAM requirements will usually be on the website.
That leaves two sections - Images and Versions. There should be a matching entry in both places. The images section is a list of virtual hard drives and CD-ROM images to use in the VM and includes:
Let’s update this file. There are a lot of old images listed as options. I’ll remove the image and version sections for 14.04.5.3 and add the most recent (16.04.7.1). That will leave users with the last 14.x and two images in 16.x including the latest. Whether dealing with a distribution or a commercial image, changes made between versions may introduce new processes or bugs so leaving some older images gives users an easy workaround. Here’s the updated file. Scroll below the output for a discussion of submitting this back to the project.

In GNS3, go to File > Import Appliance and make sure that your appliance imports correctly. GNS3 will provide guidance if there’s a formatting error. Looking at the JSON above, you can imagine that a common mistake is unmatched brackets!
If the GNS3a file loads, test it by creating an instance. You need to test at least any new versions you added. Make sure the appliance boots without error and that expected interfaces are available.
Once the pieces are working, submit the appliance to the community by cloning the GNS3-registry on Github and adding in your file.
git clone https://github.com/GNS3/gns3-registry.git
If you’ve already cloned it, make sure that your branch is up to date. Upstream is the original source (in this case the GNS3 copy).
git fetch upstream
Two Python programs are included in the repo. Run them both on your copy before continuing. These are QA processes that look for issues before you submit. They will take a little time to run.
pip3 install -r requirements.txt # this does __pip3 install jsonschma__ and __pip3 install pycurl__
python3 check.py
python3 check_url.py
Next push your local copy to your github copy. In Github terms, origin is your copy on Github, and master is the local copy.
git add .
git commit -m "Updated Security Onion"
git push -f origin master
Now we have an up to date local copy of the gns3-registry that includes our updated gns3a appliance and we’ve updated our fork on Github. Next, we offer our update to the project via a Pull Request. You are going to be one of the cool kids!
Go to the gns3-registry repository on Github and select the Pull Requests tab and click the big green New pull request button. Under Compare, select the link to compare across forks (since your copy is a fork) and select your fork. It should show you the changes to files so take a moment to digest that and make sure this PR is doing what you want. Finally, submit the Pull Request. Github will email you when there’s an update to the request. If the GNS3 team has a question, they’ll submit a comment on the PR and leave it open for you to resolve. Otherwise, it will get merged in and all the other GNS3 users will be able to enjoy your hard work!
Thanks!
