Fedora :: Open Graphical Applications Through SSH - Remotely
Mar 21, 2010
I have a small question regarding remote access through SSH. Here is the thing: it's been a while now that I am using SSH to remotely login servers, and more recently my own machines to transfer information from my school's workstation to my Aspire One (I effectively work in the Aspire One through a 24 inch monitor).
Anyway I was wondering if it is possible to open programs like evince through SSH. I'll describe what I am doing: the Aspire One sits next to my workstation (so I am seeing it's screen as well) and in the workstation I work in LaTex documents actually residing in the Aspire One, so what I want to do from time to time is to open graphical apps in my Aspire One from my workstation through SSH (needless to say that I open the graphical session in the AO with the same user I do SSH, and the AO runs Fedora 12).
I can set my EDITOR variable in my .bashrc to e.g. gedit, which is a nice graphical editor on ubuntu. But when I log in over PuTTY that editor will fail.What is the best way to detect if I'm logged in and can run a graphical editor, or not, and set EDITOR appropriately?
I recently acquired an android device and would like to be able to ssh into my machine and launch certain X applications ( Amarok, other video players) This works well when I launch server tasks that don't require an interface, however when trying to launch Amarok on the host from a remote session, I get an error about DBUS and display obviously. Just to clarify, I do not want them to launch on the phone itself but on the host, If I start them manually while at the host II can then control them remotely fine once they are started. . .
I'll say this first: we want to NOT USE WINE. we don't care how much WINE has advanced, want to avoid reliance on an outside program to run this.
I've been planning a game with someone and we want it to be able to run on linux (Umbuntu base) without wine. It should be able to also run on Windows as well, however.
The game will be a graphical MU* with combat and item systems. We have no budget- it's a shoestring sort of thing.
Here's what has been hashed out so far: Programed in C#, maybe with some .NET graphics will be 2D, however, a 3d effect is wanted for things like ascending and descending (Z axis) Partner wants to use Tom Shane's GUI library (Neoforce Controls) Partner wants to use flatredball as graphics engine I don't care what is used as long as it works without WINE
Here's the problem: Flat red ball uses Direct X and is not openGL compatible (that I'm aware of) and my partner wants the effects from the flat red ball engine. Also, the GUI library he wants is also not openGL compatible.
We need some other opensource or freeware graphics engine that can do things like flat red ball but still work in Linux. GUI packs are also nice. I Tried suggesting but Partner has issues with....Mono - Mono.XNA won't work directly using openGL - thinks it's "too hard" after playing with OpenTK even though I told him they aren't the same Java - too clunky Horde3d - Wouldn't even look at the link
We've only been working on planning stages and aren't too in-depth yet. Also, his former interest in making this run in wine without Linux seems to be dipping right along with a marked increase in wanting to rely on Microsoft.
I was tackling this question before using specifics and got nowhere, so now I am going to general. I have a certain application on my machine and many files which can only open using that application. When I open those files, they do not use that application, but use the Archive Manager instead. When I go to "Open With" --> "Other" this application is not in the "other" list. I want to emphasize that because so far everyone assumes too quickly that I didn't try that. This application was installed using the Software Manager, the files that came with fedora. The application is on my machine, this is a fact. I am able to go find the application and open it up manually. Why wouldn't Fedora know that this app is on my machine?
I have been searching and searching for the way to make the taskbar just display the applications that are currently open on the current desktop. It's maddening to click thinking you'll pull up the terminal that's hiding beneath the browser and be whisked away to a different desktop.I'm running KDE 4.4.3 and FC13. I know there's got to be a simple option to have the taskbar only show what's there...I've changed it before in other distros and just can't seem to find a clear, obvious option for that this time around.
I have a while(1) loop, and the error is: glibtop: open (/proc/stat): Too many open files This error occurs after about a half hour to an hour of running. I've tried running this multiple times, both with using glib_close() at the end of the loop, using glib_init() and glib_close() at beginning/end, and just using glib_init(). The strange thing is these have no effect on the actual glib_get functions.
I have a problem with one of my new OpenSuse installation. I install ntop on this machine so the port 3000 become open, but when i want to use it on a other pc, it cannot see the open port. I really don't understand why i cannot access this port.
I disabled firewall to make sure everything pass.
Here my ntop on my localhost
Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds
Here my ntop from another host
Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds
I'm trying to set up an SSH connection from my school to my home, but not on port 22. I originally tried port 2222, but it didn't work. I called my school IT people and they said they block that port. I asked if they care if I set up an SSH and they said no, but that they wouldn't tell me which ports are blocked and which are open for "security" reasons (which I guess I can actually understand). They suggested just using port 22 or 222, but said if a ports open I can use it.
My question is, can I check ports without setting up SSH? It seems like a hassle to try a different port every day on my home SSHD file, come to school, see if it works and repeat. Is there a way I can check my computer home for connections that could connect, even if there isn't a service listening? I don't know how to do that, or even if its possible. If not, I suspect I'll just try a few until I find something that works, or just go ahead and use 22.
I have successfully installed ns-2.29 on ubuntu and even patched in mannasim. the "make file" of ns2 is sucessful as well. The problem arises, whenever i try to run a tcl file.. eg: example1.tcl it gives an error regarding nam. I have installed nam-1.11 and configured it too. It is however unable to open the graphical window. Moreover, no trace files are created, nor any output is found in "nam.out"
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!
I have a system with 2 hard drives (Ubuntu 10.10 and Windows XP) on them. Grub allows me to select which system to boot to.
Ubuntu 10.10 has stopped working (not loading gnome graphical interface) for some reason.
I can boot to a command line (after many errors on screen). When I try the command "gnome-terminal" I get: "Failed to Parse Arguments: Cannot open display:"
I'm running Ubuntu 10.4 netbook remix on an Asus Eee PC 1001PX. uname -a says: Linux localhost 2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:12:52 UTC 2010 i686 GNU/Linux
I can't open the GUI for most of the applications in system > administration and some in system > preferences. In preferences IBus preferences, Main Menu, Prodcast Preferences, Ubuntu One are affected and in administration only Disk Utility, Login Screen, Synaptic, Network Tools, Time & Date, Users & Groups, Update Manager do start (Sorry, that I state the apps that run, but this list seemed shorter to me.). There's just a notification prompted that the program is started but then nothing happens.
Further, the update manager posts a notification in the panel that "A problem occurred when checking for updates." I have the feeling that this occurred at the same time as I couldn't start the programs anymore. Up to now I wasn't able to find out what the problem is, but I didn't touch the software sources. I read threads about similar problems and there something seemed to be mixed up with the files /etc/hosts and /etc/hostname. But I checked on that and it's fine in my case.
I can't get many applications to open on my ubuntu 9.10. As far as I know, it's in a fresh install state, so it shouldn't be missing dependencies....For example, if I try and open Pidgin, it'll appear on the taskbar for a few seconds and disappear again. Running in terminal gives:michael@linuxserver:~$ pidginBus errormichael@linuxserver:~$ I also can't get Movie Player, Empathy or evolution to open
- open terminal and type gconf-editor - apps -> metacity -> global_keybinding and look for panel_main_menu - right click and edit, change value to "Super_L" without the quote.
i've tried different vncservers and with all of them, when i use vncviewer, i'm unable to open some applications. for instance, i can open firefox and terminal. but other programs are giving me problems, like google chrome or the disk manager, which will open for a split second and then disappear. i am so mad i've looked all over the place for a couple days and ready to pull my hair out. i've installed vnc4server, tightvncserver, and a couple others i can't think of right now.
when the properties of a file change the default application, such as pdf or okular for gwenview for photos and to open these from the nautilus is opened as if they were full screen.
Just installed OpenSuse 11.3 kde version on my laptop. After install added few repositories and updated the system. Now the whole desktop looks very polished however problem started after that. When i tried to open Dolphine, Fire fox, Terminal or for that mater any application nothing happens. None of the applications opened successfully. Then i tried to configure plasmoid widgets and for my surprise all worked fine. With this problem i can not login to opensuse desktop.
When a new instance of a running KDE 4 application (kwrite, konqueror, etc.) is run under opensuse 11.4 with KDE4 it seems that the default behaviour is to open a new tab in the running instance.
This occurs when the new instance is called from the command line; the start menu; the run dialogue; or a desktop icon, even when called from a separate desktop. In konqueror the menu option <File> <new window> opens a new tab and seems redundant.
How can a user force KDE 4 applications to run a new instance in a separate frame / window when another instance of that application is already running?
I was trying to install some Windows applications in Wine/PlayOnLinux. The result was not very useful for what I wanted and I removed all the application including wine and Playonlinux completely from my computer (9.10 64bit).But I was not really able to completely clean up what I did because when I right click on any files and use "OPEN WITH", I got a LONG list of application with many of them are uninstalled and duplicated.
it's really easy to launch an application using alt+f2 without having to worry about it while it's running but in terminal the window must remain open and you can't run anything else while the application is running e.g. firefox, rhythmbox. does anyone know how to run applications in the background while using terminal?
I am looking for an application that works in both linux and freebsd (windows would be a plus) that keeps a file tree in sync in the background like Dropbox does. I can no longer use Dropbox because it does not support FreeBSD (you might see a forum thread saying otherwise, but its fix is out of date). The application does not have to sync to a separate web server, I can host from my house, but it would be nice. A system tray icon to check on state would also be nice, but not required. The platforms that I really need are kubuntu 9.10 and FreeBSD 8.0.The simplest thing I could think of would be a script that had git update a repository with all my docs in it every minute or so, would this work?
I always wanted to get into writing open source applications for debian. The only problem I ever saw was that I do not know C++ which seems to be the popular language to build applications. My expertise is Java and I think that java applications could run on debian just as good as C++ applications. What I do at work is write applications in java for unix systems so I think I porting my skills over to debian would not be a problem. I have not seen any applications in java on debian yet and thought people might have a problem with them. Is there any reason more java applications are not being written on debian? Also does anyone know of hand if there is any orphaned java application for debian. I had a look on this page but it is hard to know what language the application is written in. [URL]
