[EDIT]
If you are seeing this, it means that I'm not interested in this thread. I'm not marking it as "solved" because I haven't found what I was looking for but I also have other priorities now so I may come back in the future. So yeah If you know and want to send something I'm fine but probably you shouldn't spend you time. thanks!

I'm searching for an OPEN SOURCE software that can be used to remote access Windows computers from Linux and the opposite (both of them must be true) with fully graphical access. I want to be able to do that over internet and learn how to do that (great documentation or other guides). Can anyone guide me and send me some links?

What specific kinds of "access" are you looking for?

In a home to office type scenario?

Personally, I use a combination of a few different technologies:
- OpenVPN creates the secure tunnel. They have a community edition which is open source and free. Their documentation is excellent.
- KRDC to control Windows boxes via RDP. This works with VNC too.
- SSH (in reverse) to allow connections to my home machines, which are behind an ISP supplied router/firewall.

Otherwise, if you don't mind using Google, there's Chrome Remote Desktop. This will allow you to connect several computers and access them from anywhere. It's free, but I'm not sure if it's open source... and I think it connects via their servers.

I want fully graphic access. I want to be able to use both my keyboard and mouse.

Thanks a lot. All of them our awesome but they won't fix my problem as I'm searching for something that will need the less setup possible because I'll have other people using it too and I don't think they'll make the effort installing and setting up all that software. Now for Chrome Remote Desktop... Well I would never trust google for something like that Have a nice day my friend!

You have to consider if your other people have a public IP address. Not everyone has one these days.

Most home ISPs using dynamic IP addresses and while many never change much you might want to setup a free DNS service so that you can use a URL

Most remote desktop applications are direct connection which requires forwarding a port to a specific IP address on your network. This requires the other people to to be able to access their router configuration setup and since most computers are setup as DHCP you should just in case setup an address reservation in the router so the desired computer always has the same IP address.

Since you are connecting over the internet you also need to consider security. Not all remote desktop applications use encryption and some rely upon ssh.

Take a look at xpra.

This sounds familiar:

You marked that thread Solved...yet opened another nearly-identical one?? Read the LQ rules, and also read the "Question Guidelines" link in my posting signature. Is there a reason you cannot do your own Internet searches, or why we should look things up for you?

Damn that's a lot of work, lol. But yeah I'll probably have a look at it. I found "xpra" in another thread and that's actually what made my make this thread. Thanks a lot, I'll do my own research from now on and I'll ask for help only If I need to.

Damn I forgot about that thread! I marked the previous thread as [SOLVED] not because I really found the software but because I didn't had more time to spend on this topic so I wanted people to know that they should not spend more time on writing on this post and now this just got in my mind again (I'm an idiot cause I don't need it right away) after seeing another post and I just made another question asking about it and I will not mark this as solved but I will inform people to not care to comment anymore and I'll be sure to keep that in mind in the case I want to come back later in the future.

Now I want you (and it's not only you) to understand something. You shouldn't suppose that someone hasn't done their own research before posting. Hell, I've researched A LOT about this topic and I tried to also make things work with a friend. So yeah asking a question is ALWAYS my last resort in something while after HOURS of research I haven't find any solutions that work for me. Also I NEVER said that anyone should make research for me. I'm asking for help for people that ALREADY know how things work. I understand that you don't want to answer "stupid" questions but anyone should feel free to make "stupid" questions without getting pointed at else people will go away and Linux will got (it already has, I know that really well) the reputation of being a toxic elitist-only community and then screw us all... And in the end, If we are not allowed to post any question we want, the LQ Rules should make it very CLEAR that only smart questions are allowed

The rules for SMART ways to ask questions are not there to satisfy some picky nature of the owner, they are there to help you get the answers you need.

I understand now that the question is about desktop access. Now, desktop access FROM what or where, TO what or where? What local technologies are in use (oeprating systems, networking, internet access)? Have you VPN experience if that is required for security?

There are about 6042 answers to your question, depending upon the details. Let's try to narrow that down a bit.

That was only a month ago.
You say you 'researched A LOT'...but couldn't find all the information you were given a month ago? And unless you post back and say something like, "I tried program XXX, and this doesn't work for me. Program YYY is closer, but can't do <FEATURE>. Any other ideas?" We have NO IDEA what worked for you or not, do we? When someone doesn't mention any of the things they've done, how are we supposed to know?? We only know what you tell us...you still haven't said what you've done or tried. What programs you've downloaded, etc. Just asked again for more links.
First post in this thread said, "Can anyone guide me and send me some links?"...seems like you asked for people to send you links that they had looked up.
This is a common thing posted here, but I feel you're missing the point. There is a difference between not knowing something, and not TRYING. You were given many starting points a month ago, along with many pieces of software (and links that you were given), and posted terms which you could have used to try to do further research on your own. Based only on what you posted, it doesn't appear you did that, but rather asked us to look things up for you and send you links. While you may have done such research, we cannot know this unless you tell us. Again, I suggest you read the "Question Guidelines" link.

All that aside, either TigerVNC or UltraVNC are open source, cross platform, and as secure as such things get. If you want them to work over the Internet, you will have to configure your routers (on BOTH SIDES) to have the appropriate ports open, NAT'ed to your systems, etc. Until you do that, nothing will get through. Otherwise, you can use Teamviewer, which will work with zero router configuration, but is not open source.

Ah, that old argument.
Two answers:

1. Unfortunately we have to suppose just that, statistically.
2. It is your job to present the problem and everything you did to try to solve it, so that we know what possible solutions we should offer to you, and what not. So, don't be lazy in your first post. Tell us everything. That in itself often goes more than 50% toward a solution.

I saw that other thread, you really are asking a near-identical question there.
And there, as here, you lost interest the moment you were asked to do your part of the job, i.e.: provide more detail.

Cygwin - is open source - these are the same applications as for Linux.
