VNC from browser, no Java client, 1 port to forward

Post by eduvnv »

As most long time users of UVNC know, traditional web based VNC connections relies on a Java client served out on port 5800. That Java client then connects back to port 5900 exactly like a installed software client would. This solution works sometimes, but not every where, every time.

EduVNC is a web based VNC server that overcomes that limitation. Instead of a Java based client it uses AJAX technology (HTML and JavaScript) built into every modern web browser. Rather than connecting back on a different port, it uses standard HTTP traffic on the same port. This allows it to work on proxies, SSL VPNs, and many other places traditional web VNC fails.

The design is focused on meeting the needs of large educational environments, but it applies to pretty much anywhere you would use traditional VNC. As the developer of EduVNC, and as a long time user of UVNC, I'm extending an invitation to UVNC users to download and try out EduVNC for themselves.

I should probably also mention that EduVNC is based on a reworking of A-VNC for those familiar with that software (currently about 6 posts down in the same forum). A-VNC is ok, but it only supports one server at a time which didn't work for my needs. EduVNC rewrites the server side code to handle multiple servers with different setting combinations, etc. Most of the client is the same with the exception the EduVNC uses hashed passwords instead of plain text.

so let me get this right ... you have take a opensource project, made some minor changes to the code, and now you want to charge $10,000 for an organisational license ...

i think your dreaming ... but good luck ... i will stick to the [topic=11262]WebVNC[/topic] i think ...

BTW ... where's your changes to the source code ... you have to release the changes to remain in accordance with the GPL ...

I really hope to see these new features and others on the original A-VNC project, source codes included :)

I'm one of the developers on the A-VNC project. It's licensed under the MIT license, and I'll quote the license here, so you don't have to behead Jeremy or anything:

Code: Select all

Permission is hereby granted, free of charge, to any person
obtaining a copy of this software and associated documentation files
(the "Software"), to deal in the Software without restriction, including 
without limitation the rights to use, copy, modify, merge, publish, 
distribute, sublicense, and/or sell copies of the Software, and to permit
persons to whom the Software is furnished to do so, subject to the 
following conditions:

The above copyright notice and this permission notice shall be included
in all copies or substantial portions of the Software.
So technically, he doesn't have to release any source, and its okay for him to charge for it as well. We'd obviously like it if he did... who knows, maybe future versions of our A-VNC could go GPL, but I doubt it. Anyway, he's done quite a bit of work on it, from looking at his features list. I think it's worth the $10 personally.

Edit: You might have been under the impression that it was GPL because it has VNC in the name. The fact is, it's not based on VNC at all, and it's only used so know that this is a remote control program, similar to VNC.

Thanks, SpiderX. When I found the project of Google code I thought it was abandoned and I'm very happy to hear someone is still working on it.

The licensing is sold in packs (the $10 gets you 10 computers), so most people will realistically end up paying about $2 to $5 per licensed computer. It is also free for educational use in non-profits and public schools.
I try to make it clear on the website that I'm only looking for enough money to pay for continued development and hosting. I've spent a fair amount of time on the improvements and writes I did, so at this point I'm hoping just to break even.

It's not abandoned (yet) - if you find bugs, go ahead and report them and I'll take a look. I've managed to handle all user reported bugs. The bugs that I report are ones that I can't manage to fix on my own. I'll need some help with javascript to report the proper keypresses for up arrow, down arrow, etc...
