Server :: How To Check Multiple Processes?
Jun 13, 2011I have running license server on my server. Right now I would like to write small status script and check if software is running.My software include 3 deamons:
1) daemonA
2) daemonB
3) daemonC
My script should check, if each of this deamon is running. If all deamons are running then script should print short output: "License server is running" if one of this daemons is not running, output should "License server is not running". Is it possible to write small loop to check it ? Let say, loop will take new daemon name from deamons pool and will check if its running. Sometimes I need to check more than three daemons of one Program and I dont know how to write good script for this. Maybe somebody could help me with this loop that in the future I could also use; daemonD, daemonE, daemonF.etc.etc. if all daemons from pool is running then..."Software is running"

May 24, 2011I just updated to 11.04, and noticed in the "Background" tab of the appearance app, that there was what looked like a default option to cycle a set of backgrounds. However, when I selected it, the only background that appeared was the first one in the series, and it never cycled.
1) Is cycling backgrounds possible?
2) If so, can I create my own series of them?

Ubuntu :: Endless Boot Cycle With Xp In Grub2
Mar 23, 2010I have recently been unable to boot into windows xp, which is on a drive separate from my linux installation. When I select the windows installation, the computer starts back at the bios screen and returns to grub endlessly. I am running an updated 9.10. The linux will boot fine; however the most recent kernel does not show up on the list of available options, which may indicate something. I have searched the forum and found nothing that helps. There are plenty of posts asking if you have stopped using windows altogether and other non tech related posts though.
The results of sudo fdisk -l are below:

Apr 20, 2010I have a client who has for the last four years been running a Red Hat 4.1.18 Server with absolutely zero problems.

When they tried to reboot, they get a kernel panic. This is what the screen says;

Feb 2, 2010I'm running Debian Sid amd64 on a Vostro 1320. Both hibernate and suspend works fine using the kernel hooks, but after the system resumes from hibernation, it starts to get really sluggish. Iceweasel hits 100% CPU use, and I have to close it and open it again to get it working, and generally the system is just must slower than before the hibernation. I have to reboot to get performance back, and even doing swapoff and swapon does not solve the problem.

if anybody who uses testing has any clue as to whether there is a fix coming from the upstream, or if there is a config fix for it.

I have run Memtest successfully from the GRUB options and no errors appear in the results. I have tried booting from a Live CD and here I get as far as the "OS choosing screen". When I then select one and hit Enter, the screen goes blank and the machine reboots as before.

View 6 Replies View RelatedGeneral :: Loop Terminates / Quits After Single Cycle
Jul 14, 2011I tried to find an answer to whatever is happening with my sh, tried a few approaches, but none is working the way I planned... the loop quits with exit 0, runs once, if I comment out 'ffmpeg' line, it runs N times as it should - ffmpeg does not error out other than 0.
Code:
find . | grep .mp3 | while read filename do
newfilename=`echo "$filename" | tr ".mp3" ".ogg"`
ffmpeg -i "$filename" -acodec libvorbis -ac 2 -aq 4 -y "$newfilename"
echo inside #4debug
done
echo outside
This sh runs once, echoes "inside" 'n "outside" once, exits with '0'... unless ffmpeg commented out. I also tried to feed the loop with: done < /tmp/fname.list. BTW, this works well - but I am very interested in the >while read< loop giving up.
Code:
for i in *.mp3; do ffmpeg -i "$i" -acodec libvorbis -ac 2 -aq 4 -y "$(basename "$i" .mp3).ogg"; done
General :: Unix - 'man' Command: Search For A Word/phrase And Cycle Through?

View 2 Replies View RelatedUbuntu :: Login Cycle Loop After Username / Password Entered
Aug 12, 2010The login cycles- I already have a problem with mounting something connected with USB (long term minor annoyance, but everything works), but suddenly I cannot log in. When I put my username and password in, the screen flashes black for about half a second, then the login screen re-appears. If I put the wrong password in, I get an authentication error message (as expected) without turning black and then cycling again.
I have no problems going into terminal mode and logging in. I've tried all sorts of suggestions related to this problem- reinstalling ubuntu-desktop, apt-get clean, sudo startx, and the last indicates that x-windows is already running. I've found a couple more things to try, but I'm not too sure how well they'll work. It seems to be connected with x-windows, but I don't know what is causing it. Last night I had a big problem that required reinstalling nautilus (couldn't set up a connection to a remote server), and that problem was fixed- but this developed when I booted this morning.

CentOS 5 Hardware :: Laptop Hard Disk Load Cycle
Apr 26, 2009A while back I decided to use CentOS as my main day to day operating system :) Previously I was mainly using Fedora (old Red Hat <9.x) and occasionally Debian / Debian based distros.Since I am running CentOS on a Dell M1530 laptop I am concerned by the Load Cycle issue that plagues many laptop hard disks due to aggressive default power management. For those of you who are not aware of the Load Cycle issue please refer to the following link from Ubuntu forums which documents it really well:URL...
In Fedora and various other distros I have successfully used Laptop Mode Tools URL... to help set the hard disk APM value meaning the hard disk would stop rapidly increasing the Load Cycle value when running on mains. The setting I choose to use was hdparm -B 254 /dev/sda when the laptop is running off of mains power and set in scripts supplied with the Laptop Mode Tools RPM which will run as a service.
The problem I am having with CentOS is I can't get Laptop Mode Tools to run as a service either from the RPMForge repo (old version) or by installing the latest Fedora version from Laptop Mode Tools site above. I am therefore having to manually set hdparm -B 254 /dev/sda when running which I occasionally forget An error is seen during boot but which changes the CentOS boot to verbose mode but I am unable to locate the error in any of the /var/log files so I can put it in here.Can anyone suggest a way of creating a script suitable for CentOS which will auto apply the above (or other) power saving value for when a laptop is running off of mains power?If anyone can also advise how I can confirm what the error is I can also forward it to the author of Laptop Mode Tools.
Ubuntu :: Boot Into Single User Mode Or Escape Out Of This GDM / X11 Fail Cycle?
Jul 3, 2011I installed Ubuntu 11.04 and it refuses to show me a boot menu so I can select single user mode. When it does boot, it continues to cycle as X11 fails, but will not let me change into any of the consoles via control+shift+1-7 or control C or any command. X11/GDM continues to cycle as I hear my video card keep spinning up and down. In every version prior, after 3-4 fails it would give you a shell and say, ok it failed. how to boot into single user mode or escape out of this GDM/X11 fail cycle?

View 2 Replies View RelatedDebian Configuration :: Reboot Cycle Running 64bit Squeeze On Intel T3200 Dualcore
Mar 13, 2011running Debian Squeeze (standard 32bit squeeze Kernels linux-image-2.6.32-5-486 and linux-image-2.6.32-5-686) happily without trouble on a 64bit capable Samsung laptop featuring an Intel T3200 Dualcore processor. However, when I try to boot using the squeeze 64bit kernel (linux-image-2.6.32-5-amd64) the system proceeds through a few text lines immediately after Grub, and then performs a warm start.
The text output I get immediately after Grub look similar to the ones I get booting the 486 and 686 kernels, without any indication for the reboot behavior. The rebooting also seems to happen before any entry is written into the boot/system log files (logging is enabled). This behavior also occured when I first tried to prime the machine from the Debian squeeze install CD using the amd64 kernel. I'm generally happy with the 32bit kernels, but I'd like to use the amd64 support to do some Java compatibility testing for 64bit architectures.
The Laptop is a Samsung R510-Aura T3200 Delfina with the following Hardware and Setup (using Grub as boot loader):
- Intel Pentium Dual CPU T3200 @ 2.00GHz (see http://ark.intel.com/Product.aspx?id=37160 for details)
- NVIDIA GeForce 9200M GS
- 3GB RAM + 1GB reserved for GeForce
- Konfiguration Details:
-- Phoenix Bios
[Code]....
Maybe a strange BIOS-Setting that works with the 32bit kernels but not with the 64bit kernel? I've seen a post on here that indicates someone is running the amd64 kernel on a T3200 successfully, and the chip is definitely 64bit capable, so the reboot behavior is a complete mystery for me
Fedora :: Proliant G4 Becomes Non-responsive @ 100% Wait?
Jul 1, 2011I've installed both Fedora 15 x64 and Fedora 14 x64 on an HP Proliant DL380 G4 with the HP SmartArray SCSI controller, 2x146GB UW320 SCSI drives.The server was running RH v4 with a hardware RAID 1 with uptime of 400+ days with no issues.I broke the HW RAID and made 2x volumes and software RAID. I have another identical server with 4x 146GB UW320 SCSI drives with Fedora 12 x64 and SW RAID, so I figured 14/15 should be the same process.What happens is the server runs great for a while, but when I leave it for a few hours, it becomes non-responsive. I've re-installed 15 and 14 multiple times now and also installed NRPE, which shows load increasing to the point to where the server is non-responsive. It hits high load levels (as reported by NRPE). The load levels appear to be increasing over time. Such as last night:
log off at midnight, load average 0/0/0
2:03 am - WARNING - load average: 9.91, 8.85, 6.75
3:03 am - WARNING - load average: 16.91, 15.86, 14.47
