I need a replacement browser. Currently we use Exceed to access our RHEL 6.4 box. Works pretty well.
Now, on our replacement RHEL 7.2 box, XDMCP with GDM does not work. Why is not important, but it seems to lead back to an install from the OEM. Vendors, vendors, and more vendors are working the issue. They all are telling us that XDMCP is no longer recommended.
Since I cannot arrange access for our users via our current Exceed browser, what is a good replacement for remote host access? Does anyone know what is recommended?
Requirements: Runs on Windows, GUI, Nautilus, desktop access, new terminals and GUI open quickly within the app.

Is there any software working like this?
Runs as a standalone program. No install is needed. Thus, can be used as an Ansible module.
After running the program in a remote Linux machine, I can open up a web browser, then open a web page provided by the program. The program provides features similar to file explorer, IDE-level code editor, debugger, etc. In terms of debugger, there is already similar one; gdbgui.
There is another way such as Gnome, KDE or X11. However, these requires much packages to be installed. I don't want they be installed, because my Linux machines are kept to be small and secure.
You might consider having some terminal emulator running inside a browser. Such things exist, e.g. libonion has oterm as an example application. Then you can do all the things that a command line interface thru a unix shell provides (of course, you won't be able to run GUI applications, e.g. X11 clients such as GTK or Qt applications).
You could also consider some webmin like stuff.
Notice that you don't need to have a desktop environment on a remote Linux machine. Most of them (e.g. internet servers) have only command line interface.
Learn more about X11: you could have an X11 server on your laptop (e.g. under Windows if so needed) and run remotely X11 clients (that is GUI applications) with ssh -X on your remote Linux system.
However, these requires much packages to be installed. I don't want they be installed, because my Linux machines are kept to be small and secure.
I don't understand that requirement. On my VPS, running in some OVH datacenter, I do have X11 client applications (notably emacs). I don't believe that lowers the security of my system, and the disk space consumption for X11 applications and libraries is small enough these days. And of course I use standard commands (like cp(1), mv(1), rm(1), grep(1), find(1), less(1), file(1), sed(1) ....) to manage files. Any graphical file manager is useless (and I never use them, while using Unix since 1986)
You really should learn how to use the command line on Linux. It is incredibly powerful.
I have a GPS 84H-3 sat nav which runs on windows CE. It uses iGO for navigation.
The interface has an icon which opens the Windows CE desktop. It appears to give unrestricted access to the file system. It has reader versions of various MS office programs; other than that it seems to serve no purpose.
I have 3 questions:
Why would the manufacturer leave access to the desktop in the devices interface?
Is it possible to download and run an updated version of iGO on the machine (I found that the existing iGO version has a icon in the programs folder and the non-Windows interface has a app which lets me set the file the system runs when I click on the navigation icon; remember that the file system is accessible)
Is it possible to run alternative navigation software on the machine?
this question is not well suited to Stack Overflow, but I will try to answer:
1) to allow users to run other programs, simply to make this device more user friendly.
2) probably yes, I suggest you ask iGO for any updates to your software
3) I suppose yes, but you must be aware that navigation software very often needs some form of integration with device, ie. it should take over the sound subsystem of your device while generating navigation voices, it should allow to switch between device UI interface and back to navigation, etc. This might need some changes from navigation software side (like usage of device API).
Be aware than an embedded OS like Windows CE isn't the same as a desktop OS. The application is likely part of the OS and it's quite likely that you cannot replace it without replacing the entire OS, which would have to come from the device OEM. You might be able to "hide" the existing app with a new one, but it's also possible that any replacement will get lost when the device is restarted.
Running any other applications (a replacement navigation app or other) would depend on a lot of things. The app would have to be built for CE. The OS would have to have any dependencies the app needs. The app would have to "understand" or be configurable for any peripherals you may need to use (like the GPS).
It may be possible to install apps or override behavior, but it's completely up to the device OEM on how they implemented things. They have the choice of blocking all apps but the one(s) they want which would give you zero ability to do anything, or they may have left it wide open. Short of some formal documentation from them, testing would be the only way to know for sure.
I'm currently working on a Linux (Web-) Server configuration tool, which will allow you to easily manage all Your server-configurations in an graphical intuitive solution.
My tool is written in c# and is designed for windows.
The system will connect to a remote Linux-based Server over SSH and will then be able to configure the Domains/Subdomains, email accounts, ftp accounts, php/ settings, nginx/apache settings ... (all remote per ssh)
no aditional software/configuration needed
the system will be able to read the current config and will allow you to easily manage the configuration
I've made an short video of the product: http://www.youtube.com/watch?v=E8buUyOvZrQ
I came from froxlor(php server configuration), which I don't like at all. Because I'm using the server for myself and don't the master/client concept.
So my Question is:
Is there an equivalent Product already on the market?
Because if so, I can stop working on my own product.
Edit
Is there a tool wich works without client Installation? (not php or in any way web-based)

I built something similar awhile ago and it was a basic WinForms dashboard that managed Linux boxes by interfacing with them via SharpSSH. This was awhile ago, but judging by their soure forge page it is still maintained.
Is it possible to create GUI firewall that works as Windows and Mac counterparts? Per program basis. Popup notification window when specific program want to send\recv data from network.
If no, than why? What Linux kernel lacks to allow existence of such programs?
If yes, than why there aren't such program?
P.S. This is programming question, not user one.
Yes it's possible. You will need to setup firewall rules to route traffic through an userspace daemon, it'll involve quite a bit of work.
N/A
Because they're pretty pointless - if the user understands which programs he should block from net access he could just as well use one of multiple existing friendly netfilter/iptables frontends to configure this.
It is possible, there are no restrictions and at least one such application exists.
I would like to clarify a couple of points though.
If I understood this article correct, the firewalls mentioned here so far and iptables this question is tagged under are packet filters and accept and drop packets depending more on IP addresses and ports they come from/sent to.
What you describe looks more like mandatory access control to me. There are several utilities for that purpose in Linux - selinux, apparmor, tomoyo.
If I had to implement a graphical utility you describe, I would pick, for example, AppArmor, which supports whitelists, and, to some extent, dynamic profiling, and tried to make a GUI for it.
OpenSUSE's YaST features graphical interface for apparmor setup and 'learning' , but it is specific to the distribution.
So Linux users and administrators have several ways to control network (and files) access on per-application basis.
Why the graphical frontends for MAC are so few is another question. Probably it's because Linux desktop users tend to trust software they install from repositories and have less reasons to control them this way (if an application is freely distributed, it has less reasons to call home and packages are normally reviewed before they get to repositories) while administrators and power users are fine with command line.
As desktop Linux gets more popular and people install more software from AUR or PPA or even from gnome-look.org where packages and scripts are not reviewed that accurately (if at all) a demand for such type of software (user-friendly, simple to configure MAC) might grow.
To answer your 3rd point.
There is such a program which provides zenity popups, it is called Leopard Flower:

Yes. Everything is possible

There are real antiviruses for linux, so there could be firewalls with GUI also. But as a linux user I can say that such firewall is not needed.
I reached that Question as i am currently trying to migrate from a Mac to Linux. There are a lot of applications I run on my Mac and on my Linux PC. Some of them I trust fully. But others I am not fully trusting. If they are installed from a source that checks them or not, do i have to trust them because someone else did? No, I am old enough to choose myself.
In times where privacy is getting more and more complicate to achieve, and Distributions exist that show that we should not trust everyone, I like to be in control of what my applications do. This control might not end at the connection to the network/Internet but it is what this question (and mine is about.
I have used LittleSnitch for MacOSX in the past years and I was surprised how often an application likes to access the internet without me even noticing. To check for updates, to call home, ...
Now where i would like to switch to Linux, I tried to find the same thing as I want to be in control of what leaves my PC.
During my research I found a lot of questions about that topic. This one, in my opinion, best describes what it is about. The question for me is the same. I want to know when an application tries to send or receive information over the network/internet.
Solutions like SELinux and AppAmor might be able to allow or deny such connections. Configuring them means a lot of manual configuration and does not inform when a new application tries to connect somewhere. You have to know which application you want to deny access to the network.
The existence of Douane (How to control internet access for each program? and DouaneApp.com) show that there is a need for an easy solution. There is even a Distribution which seems to have such a feature included. But i am not sure what Subgraph OS (subgraph.com) is using, but they state something like this on there website. It reads exactly like the initial question: "The Subgraph OS application firewall allows a user to control which applications can initiate outgoing connections. When an unknown application attempts to make an outgoing connection, the user will be prompted to allow or deny the connection on a temporary or permanent basis. This helps prevent malicious applications from phoning home."
As it seems to me, there are only two options at the moment. One is to Compiling Douane manually mysqlf or two, switch distribution to Subgraph OS. As one of the answers state, everything is possible - So i am surprised there is no other solution. Or is there?
Have 4 DVI output. Seems I hopefully will have driver support on this. Details are sketchy online about supporting 4 outputs, but seems possible.
My question is from the Linux group and Virtualbox pros.... Will the seamless method of VirtualBox allow me to use all 3 of my monitors for multiscreen. I'd like to stick with Ubuntu and run Visual C# and other tools from my VirtualBox. Compiz effects are just too amazing to want Aero Glass.
What do you think, will my system be able to use the multiple monitors with VirtualBox and this graphics card? I've googled for hours and am still searching for answers.
Edit:
I tried virtualbox last night. Pretty slick, though I had an error in installing Visual C#NET. However, it wouldn't let you drag between multiple screens??? Is this something the host must resolve, or does the guest session need to have special settings for multiple monitors? Haven't been able to find anything in google supporting multiple monitors with virtualbox.
You should be able to configure your screens just fine. Don't know the exact details for an ATI setup, but you should be able to use Xinerama to create a single large virtual desktop, and then just run VirtualBox (though honestly, I prefer KVM, which runs on modern CPUs which provide native virtualization support) full-screen on one of those monitors. You would then be able to have three screens dedicated to Ubuntu, and the forth dedicated to Windows.
You might want to look into the non-Xinerama method of multiple displays. Each display is then treated as its own screen (so you'd have :0.0, :0.1, :0.2, and :0.3 for your X displays). You cannot move applications between the screens, but you get four independent desktops. I personally find that more useful than the idea of a single stretched desktop over multiple displays; when I used a laptop as my primary system, that's what I did, and when I get a second monitor for my computer, I'll likely return to that means of doing things. You'll have to investigate the specifics for such a setup with ATI, but the X server supports it, so it's just a matter of looking at your ATI driver's documentation to put the pieces together.
