how to configure X11 forwadring over SSH so, that when I open any app over SSH, I get displayed window of a process that is already running on my server (in case its running ), not a new instance of it.
View 3 RepliesSometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
View 1 Replies View RelatedI have three boxes with lenny debian recently installed. I'd like to be able to display X apps running on host1 and displaying on host2. "xhost +" would do the trick for me if I could get it to work but as far as I can tell it does nothing. (BTW, I'm aware of the security risks. This is not a concern for me. I'm safely behind a good firewall. I'm also aware of "ssh -X" but that won't quite solve my problem. See the long version below.) I suspect that Debian secures the xhost command out of the box in some way but I can't seem to figure out what it is. If that is true and someone can show me how to reset it, or direct me to appropriate documentation I think that would solve my problem.
Here's the long version:
What I really want to do is play xbattle with my kids but I need to be able to display the board to three different screens. In xbattle the command line is: % xbattle -red me -blue host1:0 -green host2:0 {and more stuff of no consequence to my question}
This opens a game board for player red locally, player blue on host1 and player green on host2. Or at least it should. If there is a way to make this work with "ssh -X" (or anything else for that matter) I'll be happy to use that instead, but so far as I can tell "ssh -X" only lets me redirect the display back to the one I ssh'd from whereas I need to direct to multiple displays to run xbattle.
I have a shell script to identify whether the process is running or not. If the process is not running, then I execute another script file to run my application. Below is my script and saved this script as monitorprocess.sh Code: #!/bin/bash
result=$(ps -ef | grep -v grep | grep "applicationname.sh" | awk '{print $2}')
echo $result
if [ "$result" == "" ];
[code]...
On my crontab there is an entry to run a script I wrote that backs up my local files to my remote server. It was working great, running once a day. However, I now want to make the script run every hour.The problem is that if there are too manyfiles to transfer (Example:I ripped a DVD in the last hour) the actual backup may take longer than 60 minutes.So I want to modify the script to check if my backup script, based on rsync, is running. If rsync is still running then do nothing and exit the script. If it is not running, execute the script as normal.

View 8 Replies View RelatedWhile running some live tests last week I saw an odd situation where netstat appeared to be displaying the wrong PID and process name for TCP connections. I'm trying to figure out if this is just a strange netstat bug or if it could indicate something odd is happening with our software.
We have a main program which establishes a number of connections, including connecting to a JMS server and listening/accepting a TCP connection. The main program also creates a child process which it uses to communicate with another server. On at least three occasions we saw a situation we saw netstat reporting all the expected TCP connections (correct ip/port for both source and destination), however the child process, instead of the main, was listed for the PID. The main process was still running but netstat no longer reported any TCP connections established by the main program. The main program continued to function correctly, the JMS communication continued to work and we believe the other TCP connection was functioning correctly despite the program supposedly not having any TCP connections.
I'm wondering if this could simply be a bug and/or obscure functionality of netstat that I don't understand which would cause netstat to report the child process as 'owning' the parents TCP connections. I don't know how this would happen or why the parent would continue functioning despite the problem otherwise.
I am starting an instance of mplayer from a bash script, opening an audio stream:
Code:
mplayer [URL]
How do I do to control this mplayer instance from another script? I want to control volume and pause it from within the bash script. I know the commands for doing so from terminal, but once mplayer gets started from the script, how do I 'direct' the commands to that specific mplayer instance?

View 4 Replies View RelatedI'm using a program called easystroke to invoke commands from mouse gestures - typically to launch an application. 'gnome-terminal', for example. If I already have a gnome-terminal window open, and I invoke the gnome-terminal gesture, I'd like to be setting focus to the already running instance, rather than spawn a new instance, which is of course what happens now. (I am actually more interested in this for my gmail chrome app shortcut, and other larger apps.)
I'm very new to ubuntu and linux in general, but I was hoping there might be a nifty command I could wrap around my launch command that would produce this behavior. (I'm imagining some kind of singleton app list keeper program that consumes my command line, checks if it's already in the list, transfers focus to the running process if it is (and if that process is still running), or else spawns a new process and then adds it to its list using the the command line as a key.)
I have KDE 4.4 and Firefox 3.6. Whenever I click a link from a plasmoid widget, it tries to open Konqueror and another instance of Firefox. The page actually loads in the opened Firefox window, but the task bar shows an instance of Konqueror and another instance of Firefox, that keeps loading for a while then close. See image below:
I currently have setup the browser default application as "firefox". If I set this option to use the default application, it opens in Konqueror and I don't see additional windows in the task bar. If I change the option to "firefox %u", then it exhibit the same issue, but the process is much faster, so the loading windows don't stay for long in the task bar. Additionally, it opens the link on a new Firefox window and opens the page twice. Although Konqueror is not loaded, the bouncing icon next to the mouse pointer shows up and stay for a while.
I posted this same issue in the Xfce support forums this morning. So far, no replies. This morning, using Synaptic, I finally upgraded my main Wheezy Xfce 4.6 computer to Xfce 4.8. There were 225 upgrades, plus 33 new things to be installed. It has been about 2 weeks since I last fully upgraded that system, so I'm sure that not all of today's upgrades were directly related to Xfce 4.8.
I waited to upgrade as long as I did because Wheezy's been getting a steady stream of Xfce 4.8 upgrades for the past several days -- I wanted to wait until that stream stopped, to reduce the chances that I would run into an upgrade problem that was on the verge of being fixed.
The only issue I had was that, in the middle of the configuration step (for lib6, I think), it asked me to either stop or restart xscreensaver before continuing (so that I wouldn't get locked out of the current session), so I completely stopped xscreensaver.

View 4 Replies View RelatedMy Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?
Since there is no notification area any more in 11.04, where is the skype icon of the running skype instance?

In Karmic, I could run an app as user gdm by issuing the following command (assume the app is gconf-editor)
Code:
gksudo -u gdm dbus-launch gconf-editor
Now that I've switched to Marverick when I issu the same command I get this:
Code:
towheed@GA1A4CH:~$ gksudo -u gdm dbus-launch gconf-editor
No protocol specifiedNo protocol specified
** (gconf-editor:19812): CRITICAL **: Failed to parse arguments: Cannot open display:
I checked my environment variable DISPLAY using:
Code:
towheed@GA1A4CH:~$ echo $DISPLAY
and it returned:
Code:
:0.0
Now I ran the command:
Code:
gksudo -u gdm dbus-launch gconf-editor --display=:0.0
and got the same error as before.Has either or both dbus-launch or gksudo changed their behavior os is this a bug. Note that the command does not work with any applications being run as the user gdm.
I have 4 workspaces set up and they appear on the bottom menu bar. Usually I can switch to each and see what's running in each, even if the apps are minimised. Now I can only see what hasn't been minimised, and I can't see or return to the ones that are minimised... System Monitor shows the minimised apps are running... I was poking around gconf editor late the other night and I must have altered a setting but I have no idea which. I've looked through docs etc but can't find a solution.
View 6 Replies View RelatedAfter downloading a Chrome (for Linux of course) installation package via FireFox. Opening it from Downloads, entering the Administrator password. Then clicking on the " Install Package " button in the " Package Installer " window, I get a message:
"Only one software management tool is allowed to run at the same time, please close the other application 'synaptic', 'aptitude', or 'update manager' first."
I see no evidence of these apps or any others running & I got rid of the Firefox. Are these " Other Apps " hidden somewhere, how do I determine this?
I really do not know how to phrase this question properly. I am quite unaware of the PC jargon. But I have Ubuntu as the main OS and Mandriva is the second OS on the same hard disk. The boot loader is the Ubuntu. When I want to switch to Mandriva, on boot up I press Shift and then select the kernel.However, if I am on Ubuntu and want to run an application which resides on Mandriva, how do I do that? My fstab file does not even mention Mandriva. However, the file system does show up that file and I can open any files I need by clicking on GUI "Places". But when I try to run any of its applications by clicking the appropriate file on its /bin file nothing happens. A pop-up window briefly flashes and disappears. So my questions are:
1. First how can I change directory so that I am on Mandriva. Can' cd ...something' take me to that file because I see it in "Places" as a 36Gb file system?
2. How can I run an application which resides on that file system e.g., R or Octave which I do not have installed on Ubuntu, without rebooting into Mandriva.
3. Can I do this from command line.
4. And finally, can I do the same from Mandriva i.e., access Ubuntu from it.
I did read quite a bit about mounting files and fstab, but the fstab does not show the file system I am talking about. These are the outputs from Ubuntu os.
I have lucid and jack almost the way I want. I can't get apps like flash (in firefox) and rhythmbox to run through JACK. I've followed some outdated guides on the forums here, but I haven't had any luck.
I set up gstreamer to use jackaudiosink, but no luck.
If you ask me, JACK + ALSA should be the default, with maybe a simplified or automated control system for people who don't want to exploit their might
I hate having to close up a massive JACK patch just to watch a quick movie, or having to close Pidgin so JACK will start.
I've just installed KDE on to my regular Ubuntu 10:04 install and thats all good and well but now when I run my fav GNOME apps in KDE, they look old fashioned like some from Win 95 or 98 type thing. Do I have to install additional GNOME Libraries and if so which ones?

my Q:
is there an easy way to run windows-progs on ubuntu 10.04 ?
Im comming from ubuntu/mint and one of the things I got used too was doing something like "sudo nautilus" or "sudo gedit" and similar things. In Suse 11.3 I always get errors like the following
(gedit:6115): Gtk-WARNING **: cannot open display:
kate: cannot connect to X server
Could not parse arguments: Cannot open display:
or similar variations of these.What can I so to prevent this from happening? even if I do "su" and try from there it doesnt always work.I like Suse as it feels more professional then ubuntu, but I am trying to make it as user friendly.
I had some problems which were were already as bugs on which kde4.4.4 crashed and since than I lost this functionality. I cannot say if I have any apps running if they were all minimized as they don't appear on the taskbar. I can switch through them via Alt-Tab.
View 1 Replies View RelatedThere are some apps for win that run on wine just with an ordinary install procedure. There are others that will never work at all. But there are also some that wine users claim to have made run by changing some specific configuration of wine, using some trick or even creating scripts on playonlinux.
So if I try to run an app on wine and it doesn't and I don't find any user documentation about some specific trick or config for that app what adjustments can I do to try to make it run? I mean, it's tiring and perhaps foolish to spend hours playing with every possible config in wine frontend without knowing what I'm doing. So what can I do to find out what libraries, configs, tricks or scripts are needeed to make an app run under wine if it didn't at the first try?
