Red Hat / Fedora :: How To Create Postmortem Data Logger
Mar 23, 2011
This is VL Chowdary, a software engineer in Bangalore,India.I am currently working on a project that deals with "Creation of Postmortem data log file on Linux platform".The project is on Fedora 12 with Kernel2.6.31.5 version.For that i need following things.1. Find the location of core utility in the kernel.2. Find the source file that consists of actual implementation of the core utility (On Fedora's kernel 2.6.31.5)3. Based on that i want to implement a core file with my own project requirements.4. Build the kernel with the above implemented corefile replacing the existing one.I couldn't get the source file that contains the implementation of core utility.

(Logger pro is an app to retrieve data from scientific calculators/ instruments) I've always wanted to ask this question so here it goes... Has anyone gotten Logger pro (Linux beta) to work w/ Fedora? I have tried alien the two .deb packages to .rpm's so it becomes installable.. The installation seems fine, But the app doesn't run (I think it was like segmentation fault or something... I don't remember) anyways.. this is not absolutely important. I'm just wondering if this may be a problem w/ my install.

I have a software RAID array using mdraid that consists of two 1.5TB drives that I use for storage, the array is mounted at /Storage. I am running out of space in the array so I ordered two more 1.5TB drives to create a 4 drive RAID 1+0 array which will be 3TB big. My question is how do I create the new array and not lose any data?
The drives and partitions are sdc1, sdd1, and soon to be sde1, sdf1. I currently have 4 RAID arrays (md0,md1,md2,md3). I think I can create the RAID 1+0 array with the two new drives, copy the data from my current array to the new one, remove the old array, then add the two original drives to the new array. But I wanted to ask on here first to make sure my data doesn't go poof.

I'm having trouble starting Fedora 14 on my computer. The startup procedure freezes while starting system logger. Before this started happening, I had formatted one of my logical disk partitions which is supposed to be mounted under the /var directory. I think may be the cause of this problem. However, I don't know how to fix it, as I can't get into the Linux command line to do a umount. I don't have a CD with which to repair the system, so is there any way to fix this problem without one?

I just installed F13 x86_64 on a system that used to be running Windows 7.
The boot drive is a SATA drive attached to the motherboard which is working fine.
However, my data drive is an NTFS partition filling a 3.6TB SATA raid.
It's GPT--Gparted sees 3 unknown partitions, and gdisk shows:
Code:
How do I mount this in Fedora 13? I had intended to shrink the NTFS partition so that I can create an ext4 partition to move the data to. Will this be possible?
I've got a LOT of valuable data on this drive, and nothing else big enough to store it.

I have a 160gb hard drive with no partitions. Ubuntu runs on the entire disc. I want to cut off 60gb from my file system as a storage drive without losing the data that i already have on it.
I don't want to reinstall Ubuntu and cannot afford to lose all my data. Is it possible to do so, without having to reinstall the OS.
I downloaded Gparted, whats next?

i want to create multiple cd's containing the data of one tar.gz file of course i can use data dump (the dd command) to cut the tar.gz into 700 MB pieces. yet then i must calculate the exact location where to cut, and use the skip, seek and count parameters to proceed. Does anybody here know, software that automatically creates 700 MB parts of a single file?

Got a Zimbra server FOSS edition running on CentOS5.5. Everything was running fine until couple of days just found out that web administration interface just does not give the proper status. Web console says that none of the services are running which infact is not true. Only service that is not running is logger. This is the zmcontrol status output
Code:
antispam Running
antivirus Running
imapproxy Running
ldap Running
[code]....
Just the logger service is not running all the others are. But web admin interface shows all are stopped. Also it can be seen that zmlogswatchctl is not running. Starting it manually does not do any good. It does not start and it dies out by itself.I tried to google and found a couple of bugs related to logger and web interface but those were old and should have been done in this version 6.

Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk
Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.
You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.
Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).

I'm trying to run LKL (Linux Keyboard Logger) in a Ubuntu 9.04 VirtualBox VM (VirtualBox 2.2.2 running on a XP host). The package installs fine, but when I try to run it lkl -l -k /usr/share/lkl/keymaps/us_km -o ./kbd.log & it hogs the CPU usage to 50% and never logs a keystroke (in fact the kbd.log file is never created)

I do the following tasks to move sdb1 to VolGroup00:
After that I moved /var back to / folder and reboot but the system hangs at "Starting system logger". Uninstall and re-install sysklogd package don't make any change. What I don't understand is I can start syslogd from command line:

Or run the init script in debug mode:

Used gparted to format a brand new iomega prestige 1 tb usb hard drive (ntfs) to ext4. The problem is that I can't create folders from nautilus because I don't have permission (root). There is one folder present already lost + found that appeared after reformatting. i can't access that folder because of permissions. Was any of this supposed to happen after formatting an external drive and how can I fix this? I intend to use grsync to back up important folders but can't create folders from grsync also. The only account on ubuntu is mine and i have access to root privileges.

I'd like create my own effects and synths and use them in my composition. I googled around and I discovered a lot of language (graphical and not) to create sound and music. But I don't understand if they can be used to create (with wrapper or indirectly) VST FX and instrument. I need to create something that can be impoted in Cubase and having a basic GUI to change its setting and attribute!
I think SuperCollider is cool, but it looks not to create something importable via VST... Am I wrong?
What about CSound and Pure Data?
