Am I allowed to rebrand Virtualmin, but retaining the MIT license?

[oliverbob]

Since this is an open source project, I wonder (and I believe people also ask whether they are allowed to customize branding) for example this file: “/usr/share/webmin/virtual-server/lang/en”

Can be changed in vs code with the following regex:

(?<==.*)(Virtualmin)

This can be tested in https://regexr.com/ changing over 278 instances in file for the following text fragment:

deftmplt_tmpltpagedefdom=Domain default page

I am a license subscriber by the way, and I tested it for this purpose of asking this question, while at the same time testing it to a hundred domains/clients. Can I just retain the MIT/GPL license to refer to some portion of the opensource, particularly the default template source containing the following:

    /*!
     * AI Cloud City Default Page v3.1
     * Copyright 2023 AI Cloud City, Inc.
     * Licensed under MIT
     */

If I’m allowed, then it follows that I can also do this to Webmin and Usermin.

A little background. I’m a newbie to virtualmin, from the frame of mind of ISPConfig and I like virtualmin so much over ISPConfig which I retained in my other server. So, I tried virtualmin today and I bought the pro version as one that is highly satisfied with the GPL/demo version.

Please let me know my limitations and freedom.

My OS is Ubuntu 22.04.03. I’m planning to use it as an AI Cloud Server for GPT and Neuralnets across clients and its currently being installed in HPE DL380 series.

I hope to be able to become a long term client of Virtualmin. I’m also planning to buy the unlimited domain license when my play tests are finished.

Kudos to the team who made Virtualmin possible.

Best regards and God bless!!

Thank you very much.

Virtualmin is not under an MIT license.

There are some bundled components (e.g. JavaScript libraries, etc.) that are MIT and/or BSD-licensed, but Virtualmin GPL is licensed under the GPL and is subject to those terms, and Virtualmin Pro (everything in the pro subdirectory) is Copyrighted (and not freely distributable). Webmin is under a liberal BSD three-clause license (so the license notice needs to remain in place wherever it appears).

But, rebranding is fine for both GPL and Pro. You should be aware, however, that lang files get overwritten on updates, so you need to plan for that. The best way to handle that is…maybe a custom lang. You could also just make a patch using the diff command and then re-apply it after updates using patch. While it does change regularly, a patch will probably apply cleanly for quite some time. Or you could just script a search/replace using sed every time you update.

For the default page (the index.html that gets included in public_html when a new domain is created without content), assuming you’re replacing the whole thing, you don’t need to include any of our copyright notices. The web pages and apps you host on a Virtualmin system are not subject to our copyrights or licenses, unless they were made by us.

There are tools for adding logos and colors and stuff to the UI without needing to modify any files. It’s a configurable option. And, you can load custom stylesheets, which could more significantly alter appearance and insert logos or whatever.

Thank you very much for your prompt and informative response Joe.

Blessings and happy new year!
