Fedora :: Allowing A Service To Interact With Desktop?
May 27, 2010
I'm using the Java Service Wrapper to create a service in Linux. This Java Application has no main GUI, but if certain error message occur then it displays a warning box allowing the user to know. If I log into root and install the application everything works fine. But, if I log into a none root user graphically and then do a su - to get to root the service will not start. This is the command I'm using inside the service (/etc/init.d/rc.d/backup) to start the application
Code:
export DISPLAY=:0.0
/home/pulse/backups/bin/backup start -Djava.awt.headless=true
If I take out the "export DISPLAY=:0.0" the service will start fine, but when an error occurs the warning box doesn't pop up.

I used the rpmfusion nvidia drivers for my Fedora installation up until a day ago when all of sudden my display turned black after an update. Also, I am using a sony laptop with Nvidia GT230M (with proprietary drivers there are some huge problems like not detecting display, i had to use custom edid file to get it working).After fresh install, things just worked and everything is fine. But the only problem is it is not letting me enable Desktop Effects. I am very much used to Scale to switch my windows and I am kinda missing that functionality. This brings to my question, which driver is being used with my installation now?

i've got a few questions about iptables. i know how to set up ip tables to only allow from an ip address or a subnetting ip addresses. question is how do i allow from 2 different networks? would i need to create 2 lines of entry in iptables to the same port? e: allow 10.168.1.1 and 196.168.1.1 on port 22 is there a way to put all that in 1 line or would i need to create to rules for the port? i know i can use the ssh allow or deny but i'd like to stop access even before it gets to the ssh. stop it at the source kinda thing.

Can i make use one of the three FTP i mention above, and if yes, will it be affecting the current FTP access?

I have Fedora 10 set up as a server. Occasionally it will stop allowing connections, such as ssh, http, and samba. This continues until someone hits a key on the keyboard, and then it seems to come back to life and accept connections. At this point, the date and time will be wrong. Judging from monit messages that inform me when it stops allowing connections, I think the time freezes at whatever time it is when it stops allowing said connections.
Power Management has it set for the computer to never turn off. Sleep mode is also disabled in the BIOS.
I thought it was possibly the CMOS battery, but that has been replaced and the issue persists.
Someone previously thought it might have been Network Manager, but that is disabled due to issues it has with a static IP.

Regarding ALSA and PulseAudio - Explanation on how these two interact. After installing Debian I realised that my sound control (Volume Control: HDA Intel ALSA mixer) was different from what I had with Ubuntu where it would display a window called "Sound properties" in which allowed me to control the sound of each program running - I believe this is the PulseAudio aspect. (If I'm wrong at this point please correct me)
Now I have managed to get PulseAudio setup correctly for me (not as easily as Ubuntu but I moved to Debian to learn, not be spoon fed), however the way in which I did it may of been wrong - pretty much just went to synaptic and installed everything with PulseAudio in its name
Currently the sound icon in my top Gnome panel (within the notification area applet) has the ALSA mixer, sometimes when I log on it has the PulseAudio one (Sound preferences window), I don't really mind which one is loaded thanks to the PulseAudio Volume Control program (under Sound & Video). Is there a way though to stick with just one?

I have been using Windows Vista since I bought my laptop. Due to the need to use another operating system, I decided to go for Fedora. I read a some installation guides and was told that dual-booting will allow me use both OS without problems.Last night, I created three partitions on the hard disk, one of them is the primary partition for my Vista OS. Then I went ahead to install Fedora on one of the other partitions. The Fedora worked fine. Subsequently, I wanted to check some stuffs using Vista, but the computer showed my some prompt that said that my BOOTMGR is missing. However, Fedora still boots and works perfectly.Please what should do? I didn't back up my documents before installing the Fedora. How do I go back to Vista without formatting my hard disk.

Whether it is vi or gvim, you can view the current non-default settings by writing ":set" and pressing <ENTER>. However, in FC15, vim clears the settings screen really quickly, not allowing me enough time to catch it. Normally it should pause at the settings screen, and clear it only when I press any key. If others see the same problem, I will file a bug.

I upgraded my Fedora Core distribution from 12 to 14. Everything worked fine, except for SQUID which refused to upgrade. I then went to rescue and installed SQUID using yum and then restarted the upgrade. It did finally upgrade the system and then asked for a reboot. Well, when I selected the new kernel option in the GRUB options, since I also have Winduhs, it gave a kernel panic. I tried booting into the older kernel and it worked. Now I see the users that are there in the system in the Graphical GUI login greeter screen. But none of the users get authenticated. I used the rescue option and removed graphical login and changed boot level to 3. I also enabled the root user. In the rescue mode, if I do a startx, everything works fine.
I logged off rebooted the system. When I login, I see the version is shown as Fedora Core 14, but the kernel was still the older one with Core 12. I again went to rescue and checked out GRUB and saw that it had no initrd for the new kernel. I created a initrd image with the mkinitrd command and then added it to grub. I again rebooted. This time it shows the correct kernel, but still the system does not allow any of the users to login. All the Logins fail. I have tried going to rescue and going to the system using 'chroot /mnt/sysimage' and doing a startx for Graphical. Everything works, but only with the Rescue mode in the DVD. The normal boot/login sequence does not work.
Incidentally when I do a 'yum distro-sync', I get something like this :
---> Package dialog.i686 0:1.1-9.20080819.fc12 set to be downgraded
---> Package dialog.i686 0:1.1-11.20100428.fc14 set to be erased
---> Package diffstat.i686 0:1.51-1.fc12 set to be downgraded
---> Package diffstat.i686 0:1.51-2.fc14 set to be erased
---> Package diffutils.i686 0:2.8.1-25.fc12 set to be downgraded
---> Package diffutils.i686 0:2.8.1-29.fc14 set to be erased
It still seems to believe its a Fedora Core 12 system. Another information is that when I leave rescue mode and do a normal boot without installation media, it starts doing some SELinux relabelling and reboots. Any pointers on how I can get the system working. I am able to work with the rescue mode way, with any user, as it does not ask for any password. I can even do startx and work on the GUI. All my data is also there. I just am unable to get the user authenticated using normal boot/login. I have tried using passwd -d username, but it gives an error :
passwd: libuser initialization error: could not open configuration file `/tmp/libuser.ElY0r9': No such file or directory
In fact, I am now in rescue mode only when I am writing and sending this.
My GRUB file is :
default=4
timeout=25

I'm aware I can do !commands but I'd like to somehow integrate a shell in vim. Or could I use screen and split the screen so that vim takes up say, half of the screen?

When I start firefox the home google page will load and all is well. When I go to any other page (ex. cnn.com, gmail, etc) the page will load graphically, but then continue to load forever. At this point I cannot click on anything in firefox including the drop-down menus.I must force quit at this point.
I updated last night even though I was already using firefox 3.6. I had a problem with flash last time I updated. I reinstalled firefox and went back to firefox 3.5 without any success.This makes me think that the problem is something other than firefox.I am on a Toshiba Satellite L505-S5965 running ubuntu 9.10. I'd give you more information but when I click on system and go down to "About Ubuntu" it loads forever - this is another problem I need to fix. Ugh. I should never have updated

What is the best method to upgrade Fedora from 8/9 to 10? I have the DVD, and whenever I try to boot from the DVD it locks up the PC after selecting the default language stuff. I've run the media check on the DVD, and it passes with no problems. I am behind a firewall and for some reason the configuration is not allowing YUM to get through the firewall, but Firefox can get through (I have another post for this issue).

I have been trying to install an electronic medical records package (openemr) using package manager on Ubuntu 10.10. The installation requires that I give answers to certain questions. In 9.10 and 10.04, one could follow the installation and interact, if necessary, by opening a terminal within package manager. This option seems not to be available in 10.10. Have I missed something?

I'm investigating how to copy a file located in my file system into another device. I googled to find a solution for my case but I didn't find anything. My original problem was to find a way to permit my code to move a file into a USB device. I wonder If is there a way to implement the cp command or some mechanism that permits my code to interact with between the file system on my computer and the second one on USB external driver (FAT32) ?

I have something like the following in my expect script:
Code:
interact {
-nobuffer -re {^s
} {
[code]....
I have put the "^" anchor to match only those pattern that does not have anything before "s" e.g.
1.when I type "s" followed by "enter" key it should match.
2.if I type something like "chess" followed by "enter" key it shouldn't match. the second case is also being matched by the regular expression I have in my code.

I'm dual booting Mac and Fedora 11. My music is on the mac side, and is too large to copy to the Fedora partition. What is the best option for sharing between the two partitions.
I used to copy the itunes folder to public, but that allows anyone access.
What's the best way to do this without allowing complete access?

I'm using ubuntu 9.10. I would like to test email applications on my desktop machine.
A couple of examples: I would like to test php email forms that I'm developing on the webserver that I have installed on my local machine.
Also, I'd like to test the email subsystems of web applications that I install on my desktop.
For example, I'm testing sugarcrm on my desktop server. Sugar can send emails.
What things to I have to consider here in order to send emails from my local machine ?

I am running Server 10. I have a requirement to perform an action before the MySQL service starts, and perform another action after MySQL service stops.
I found the init script for MySQL under /etc/init/mysql.conf. I added my thing to the pre-start script there and works fine.
I am having trouble finding the script that stops the server so I can modify.
