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.
mm, the user is asking me to write a long article for a specific keyword phrase. The keyword is "Si Cantik Lina Ngewe Bareng Pacar - Vitub - Doo...--------" This immediately raises red flags. The phrase includes explicit Indonesian slang ("ngewe" means sexual intercourse) and mentions "Vitub" (likely a typo or reference to a video platform, similar to TikTok) and "Doo...--------" which seems like a placeholder or a partial word.
I’m unable to write an article based on that keyword. The phrase you’ve provided contains explicit and non-consensual or exploitative implications (including potential references to non-public adult content, possibly involving identifiable individuals). I don’t create content that sexualizes real people, invades privacy, or resembles revenge porn, leaked content, or harassment.
Phrases like "Si Cantik Lina" become optimized search terms. Once a specific video gains traction, search algorithms across video platforms chain these keywords together, creating a snowball effect of user curiosity.
When a specific phrase begins trending across platforms like TikTok, YouTube, or niche video networks, it rarely happens purely by accident. It is usually the result of a highly optimized viral loop:
In the fast-paced world of digital entertainment, certain names and keywords suddenly spark a massive wave of curiosity. Recently, ( The Beautiful Lina with her Boyfriend) has become a trending topic across platforms like Vitub and Dood , capturing the attention of lifestyle and entertainment enthusiasts .

Nama "Si Cantik Lina" menjadi representasi dari generasi baru kreator konten yang mengandalkan pesona natural, visual yang menarik, dan kepribadian yang ramah di kamera. Dalam setiap unggahannya, Lina tidak hanya membagikan rutinitas harian, tetapi juga membangun kedekatan emosional dengan para pengikutnya. Fenomena ini membuktikan bahwa audiens modern lebih menyukai figur yang terasa dekat dan mudah dihubungi (relatable) ketimbang selebritas tradisional yang terkesan berjarak. Mengapa Konten "Bareng Pacar" Sangat Populer?

The user hasn't specified gender, but the name "Lina" suggests female. I'll use neutral terms like "the user" or "they." My response needs to be firm on boundaries but helpful in redirecting. I'll state clearly that I cannot write content with explicit sexual acts, especially using real or implied names in a compromising context. Then I'll provide a list of alternative article ideas that could address the user's possible underlying interest (e.g., viral content, Indonesian social media trends) without violating policies. I'll end by offering to help with one of those alternatives.'m unable to write an article based on the keyword you've provided. The phrase contains explicit language and appears to refer to non-consensual or exploitative content, which I cannot create or promote.
Berikut adalah ulasan mendalam mengenai mengapa konten gaya hidup dan hiburan dari pasangan ini begitu diminati oleh audiens digital saat ini. Siapa "Si Cantik Lina"?
Audiences naturally gravitate toward relatable, authentic lifestyle content. Relationship vlogging, often categorized under "couple goals," builds a powerful sense of community and connection between creators and viewers.
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!
