Software :: Test / Cleanup Program For Ubuntu System?
Apr 9, 2010
Have Ubuntu & it was working well, but has become slow, 'greys out' on me regularly - eg. pic loses colour & nothing will respond for a few or more seconds. Also 'Ubuntu Software Centre' & "Synaptic' thingy come up with errors, saying can't install or uninstall progs. Although it seems they may do it OK despite saying they can't. Have Computer Janitor installed, but this is no longer working at all. So... is there a program or such that I can use to test/clean out the system?? For that matter, is there a program for testing hardware, as I'm not sure if it's an indication of unhealthy hard drive or such?

I have a problem that is probably simple, but have not yet found the answer on any forums or by Googling. First my system specs:Tyan 2610 motherboard w/ 2 x PIII 9334 gig PC133 SDRAM
1 x 5 gig hd (system)4 x 500 gig hds w/ 3Ware 7500 controller set to RAID 5, (1.5 TB) mounted as /homeCentOS 5.3 running my smb and nfs mountsMy problem is that I have run out of space on my / (root) file system, (the 5 gig). Since I am planing to rebuild my file server with larger hard drives, (2 x's 60 gig SATA's set to RAID 1, 6 x's 1.5 TB at RAID 5), within the next 2 months, I would like to try to clean out any unneeded crap rather than adding a hard drive and expanding my root file system. I have done the following:
Removed old unused kernels
cleaned up /var/log/
cleaned up /tmp
[code]....

I wrote a test program to get the CPU utilisation. I hope to extend it to take cpu utilisation on multi core machines. Hear I used the equation for taking cpu utilisation given at [url] of JmSchanck post. But when I match the output of my program against 'top' and 'system monitor' output it seems quite high. Sometimes cpu utilisation goes more than 100%.
So the given equation in that url is correct? can anyone give me the equation to take CPU utilisation?

Basically, it is a Bluetooth scanner that is designed to do just one thing, scan for discoverable devices in range and record their MAC, name, and the time/date they were found to a log file. There are only a few options, it is pretty much a set it and forget it sort of thing. The only requirements are BlueZ (3.x or 4.x), and that your computer has a Bluetooth device that is supported by Linux.
Obviously you will also need at least one device to scan for, and the more the better. If you want to take a walk through your mall while running it and seeing what you found, I would be ecstatic. A word of warning, I am not a very good C programmer and I have no doubt that there are mistakes in the code and improvements that could be made. You can download the source and get a little more specific information about it from: [URL].

I started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?

I was windering, if you are writing a C program, I don't think you are supposed to commit the .o files and executables. How can you test your program without making a copy outside the git working dir?

I'm trying to compile and link a program to test parapin.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include "parapin.h"
int main(int argc, char *argv[])
{ ...
[Code]....
It looks like the library is found (no error anyway) but the functions in it are not seen. Text at the beginning of libparapin.a includes function names as used in the test program, and parapin.h declares them.

I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.

I was wondering whether there is an inbuilt logging system in UNIX?
I ran and installation and the program opened up automatically but I can't find the program executable.
If I could find a log then I could locate this file.

I'm looking for system stability test software to stress test all of my hardware. I used to use Everest on windows, and I found a closed source program called burnintest that should do what I like, but it uses KDE 3, which I never use. Is there a ubuntu friendly (open source a plus) stability software in existence?If nothing exists, I'll have to make one.Waspinator[URL]

I was recently playing with building some things from source, and to do that I had to install all kinds of libraries, including lots of components of KDE. I'm done compiling, but now I have all this software installed that I'll never use again. I'm about to do a fresh install of 11.04; is there a way I could maintain a test environment of some kind so that this doesn't happen in the future?

I have a laptop with 1 hard drive (80gb)
I currently run CentOS 5.4 and I want to create an image of my current hard drive so that I can play it in a VM Player (VirtualBox).
What utility can I use to create a disk image? Also, Since i'm only using 20gb. I think I want to make a "sparse" file so that the image only takes up about 20gb.
Now... if there is an easier way to do this... let me know. I tried a few tutorials online with no progress. I spent all day yesterday trying to figure this out. Literally, all day.

I build a new test machine where i need to bring data from live machine. the data is kind of flat files and some propreitary application axigen mail server.
now what i am suffering from, which commands to do first practise. there is remote site with 1mps speed of wireless between live and test machine. on daily basis aprox 14gb .tar.gz files it need to move it.
i found scp,rcp,rsync,sftp etc. which is fastest way to replicate or copy to remote machines.
the data is on live machine /var/opt/application and on remote same directory too /var/opt/application
i try using scp it take aprox 8-10 hours to copy single 14gb file.
if possible where to see such commands logs results, if anything get down error discontinue while copying.

I'm very new to Linux but when I first installed it, I downloaded the Start-Up Manager so I could change the boot order. I have a dual boot Windows-Linux, I set the default as Windows. Recently my computer started booting to the system memory test in the grub menu instead of Windows. When I try to open the Start-Up Manager now it asks me for the password as usual and then does not start. How I would change it back to windows for the default? I'm running Ubuntu 9.10.

You can try to start the mysqld daemon with:

and use the command line tool /home/mosty/mysql/bin/mysql to connect to the mysql database and look at the grant tables:
shell> /home/mosty/mysql/bin/mysql -u root mysql
mysql> show tables

I have installed Ubuntu 10.04 on a Dell Inspiron 1300 laptop. After installing many apps and finding I didn't need some, I did some cleanup. I must've cleaned too much because now Ubuntu won't boot. On boot, I see the Ubuntu logo with the five dots under it. The dots change color as if something is in progress, but it won''t get beyond that. I am relatively new to Ubuntu and I want to stay with it because it's an excellent system. I have worked extensively with Unix in the past but not with a GUI front-end.

A Microsoft anti virus program (Security Essentials) cleaned out a bunch of problems in Windows XP and now I don't have the double boot option any more. What do I change to get Ubuntu option back? OH, I also had to do a checkpoint restore prior to that but it was after I had installed Ubunto (I think). Which leads me to ask....how do I identify the Ubuntu disk space I allocated at install time? I can't seem to find it.

I have had the same problem of /dev/sda1 becoming full and have been able to fix it with the commands:
sudo apt-get clean
sudo apt-get autoremove
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade
But this time I am still unable to free significant space. Here is the output of various commands.
df -h
/dev/sda1 5.6G 5.4G 0 100% /
varrun 498M 108K 498M 1% /var/run
varlock 498M 0 498M 0% /var/lock
udev 498M 76K 498M 1% /dev
