when i try to run a program in linux it runs and prints some messages successfully but in the middle it shows the message 'Killed' and stops running. what may be the reasons for this..?
View 2 RepliesI have tried to change settings on Sound Recorder, and when I tested the new settings, a number of windows came up with the last reading: Disconnected: Entity killed but I cannot quit the program no matter what I do. The program just will not close. Is there another way to close a program?

What are the benefits to upgrading to F15 from F14 if any? Has there been some huge step forward in performance, security or some other reason that makes it worth while to upgrade? I know many people make the move simply because they wish to have the latest and greatest, but is there any reason specifically to upgrade to the latest and greatest?

So in the 2 jobs which are set to run PMDaily.sh for eg , One runs on Sunday at 8AM and the other runs monday to friday at 6 AM . How ever the Sunday cronjob works (runs through the crontab) but the Cron job set for Monday to Friday is not working. However manually if i run this script it workd perfectly.
Please let me know what could be the possible reasons for this?
I have NFS fileserver that has served me well for more than year. But recently I noticed that it has started to reboot on its own very frequently, almost once a day! It is most likely not a power related issue as I tried changing UPS/power sources, but no help!So my question is:Is there any log file where I can check which is causing the reboot? There may not be a single logfile, but I need some point to start the investigation!

View 1 Replies View RelatedMy web server does not currently run Suexec. All files within the /var/www directory are owned by vsftpd and belong to nogroup. Apparently, this setup causes issues with some scripts that attempt to upload files and change files, such as the SMF Forum package.
Here's some background information that goes into further details regarding the issues I'm having:[URL]..Why would uploading a file using PHP in SMF not work with the owner being vsftpd belonging to the nogroup when the folder has been chmod to 777? I tested my own simple PHP upload script, and it was able to upload a file without issues. Yet, I've been told that my server is improperly configured if I'm not using Suexec. Why is this? Also, if I did use Suexec, what creates the users? Would I have to add them manually, or would they be created automatically as users based on their FTP login and added as subusers to the vsftpd group? Why should I use Suexec? I don't understand what's wrong with my current setup. How does it work in terms of users? Are users created and just added to a subgroup, or are they created like normal user accounts on the actual server? Do they get their own /home/username directory as well? I'm so confused about Suexec. What I've read about it doesn't make sense.[URL]..
My suspend-to-disk and suspend-to-RAM stopped working months ago. I've grasped at straws about why ever since, but I really don't think it's a software problem, because I've reinstalled my system (MEPIS) repeatedly. What sort of hardware failures could cause this? What should I be looking for? I notice that at boot, Linux always says "no resume image found," even if I left the system in suspension or hibernation. I can post parts of the dmesg if someone tells me what to look for; I can't display the whole thing because it's too long to fit here.

View 3 Replies View Related I've recently built a VM appliance using Ubuntu 8.04 that is given to customers for an easy deployment of our software. Ubuntu works great in a VM and its perfect for our software (which is a web application).
Some customers are paranoid (rightfully so) and they will run a vulnerability assessment on the web application. A particular customers' assessment fails as it finds that the appliance isn't running the latest version the Apache web server. I thought that just running "apt-get upgrade" would upgrade all of the software packages to the latest so that failures in the assessment caused by outdated software packages would be resolved... However this is not the case...
I realize that there is a probably a whole process for submitting/approving the latest versions of software packages in Ubuntu, that then get pushed to the repositories - But how does this work? What exactly does "apt-get upgrade" do if it doesnt upgrade packages to the latest?
For example: I need Apache 2.2.11 to fix a particular vulnerability. But when running apt-get upgrade, it doesnt actually upgrade the Apache version number (or any of the other packages). I'm stuck on Apache 2.2.8, and I can't find a .DEB installer for 2.2.11 or later.
im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>
int main()
{
int length, width, length, height, area, perimeter;
perimeter = width + length + height;
area = width * length + heigth;
[Code]...
i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?
I found some interesting behavior when discussing the pow function from Math.h with someone. I am well aware of the need to compile with the -lm flag, but to my surprise this actually isn't necessary if the arguments to the pow function are literals. For example, this program compiles in gcc without using -lm:
Code:
#include <stdio.h>
#include <math.h>
int main()
[code]....
If I try to change the call to any of these:
Code:
double bCubed = pow(2.0, e);
Code:
double bCubed = pow(b, 3.0);
Code:
double bCubed = pow(b, e);
Then the -lm option is required or else it can't compile. So does anyone know why it's necessary to use -lm when the argument(s) is/are variable(s) but it works fine if both arguments are literal values? As a side note, any of the above compile with g++ however. Also, if it helps, this is the version of gcc I'm using:
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-44)
This doesn't happen on my Mac however that is running: i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5484)

View 4 Replies View RelatedI'm new to programming under linux (not new to programming). Before that I have written c++ codes in Visual Studio under windows for some years. I read some tutorials and learned editing codes with vim and compile codes with g++ or make tool. And I tried gdb.
But I think compared to my coding experience in Visual Studio, these steps are very ineffective. With VS, after I wrote codes, I just press ctrl+f7 to compile and ctrl+f5 to run the codes. If I want to debug, press f5, and I can see every variable in a 'watch' window.
Under linux, after I write codes, I need to quit vim, type make to compile. If I have some mistakes, I have to remember the line numbers and re-open vim to check the errors. And I think debugging with gdb is so hard.
I think as a newbie to programming under linux, maybe I haven't find the right tools. Or programming under linux is just so hard so a programmer who can overcame these could be strong enough to do programming without some IDE tools?
