CentOS 5 :: Re-instal Windows XP - Systems Hangs?

Mar 29, 2009

I had a spare computer (Dell Optiplex GX270) which I had installed Centos 5 on and have been setting up asterisk (telephony) on it. My main computer has broken down and I need to load Windows XP back on to the Optiplex.

I put the Windows XP disk in the drive and directed the bios to boot from the cd. I get the message "Please wait while windows inspects your current hardware configuration" and then after about 10 seconds the screen goes blank (the cd also slows down and then stops) and then the systems seems to just hang.

If I take the cd out and boot from the hard drive Centos loads normally; therefore I'm assuming my problem is not a defective hard drive.

I've spent quite a bit of time searching online for a solution and although there seems to be several different situations where the above can occur, I'guessing that my ssues are related to either partions/mbr and or the bios/cmos. I'm really new to Linux and not knowledgable on partitions and cmos so I'm hoping someone could help me out here.

I've checked in the bios and could not find an option to restore the settings to factory defaults. Should I pull the csmos datterry out? Does this restore the bios settings to factory defaults?

CentOS 5 :: Yum Update Three Systems With Only One Download?

Mar 31, 2009

I have three CentOS machines which want updating from CentOS 5.2 to 5.3 sometime in the next week or two.I've always just done su -c 'yum update' on each machine, and let it slowly download and update a zillion pkgs. And every time I do that, I tell myself that *next* time, I'll figure out a better way.

I'd like to be a little more efficient this time, and have the 2nd & 3rd machines re-use some of the packages that the first machine downloaded. Two are workstations, and the third, a headless non-X11 fileserver, so they have different (but overlapping) sets of packages that they'll need. But the in-common packages comprise a lot of downloading that I would rather do only once. There's some way to set up a local yum repo on my server, mirror *everything* onto it, and update all machines from it. But that looks trickier, and way overkill for my purpose. Or I could just download ISOs, and work from there, but two machines don't have optical drives to boot from, and the ISOs contain tons of stuff that none of these systems need, so the download savings would be cancelled out.

A little reading of forums/manpages/etc, and I think I want to make use of yum localupdate (which I've never tried before), and do something along the lines of: 1.) Update the first workstation. It'll download all pkgs it needs overnight, and then update itself: [wkstn]$ su -c 'yum update'

2.) Make sure everything is working correctly.

3.) Grab every *.rpm from wkstn's /var/cache/yum and all its subdirs, and copy these to a temp dir on the server's raid: [wkstn]$ cp -a /var/cache/yum /server/raida/wkstn_yum_cache

4.) Update any server packages that the wkstn already downloaded.[server]$ su -c 'yum localupdate /raida/wkstn_yum_cache/'

5.) Update any server packages that the wkstn did NOT download: [server]$ su -c 'yum update'

6.) Deal with anything that broke on the server. The raid drivers, for example, always seem to need rebuilding, after kernel updates.

7.) Update the other workstation.

Question #0: Will this do what I want? I've never tried yum localupdate before, and the yum manpage doesn't elaborate much. Am I really barking up the wrong tree? Is there some much better way of doing this, for updating just 2 to 4 machines.

CentOS 5 :: Yum Automatically Updated Systems Without Configured

Aug 11, 2011

I came to a "weird" situation when I saw in yum log files that several centOS systems have been automatically updated via yum. I checked the following:
1. chkconfig for init services that could upgrade the system: only yum-updatesd
2. In the config file of yum-updatesd.conf the do_update function is set to no.
3. If an updated made manually by a user ..no.
Where else should I look or how this update happened?

Ubuntu Installation :: Grub And Other Boot Systems (Windows)

May 1, 2010

I have Win7 and ubuntu installed on the same PC. Win7 was installed first, after I installed GRUB from Ubuntu, Win7 is not listed as a second option to boot. FYI, On the same PC I had Win7 and Debian (before changing from Debian to Ubuntu) and GRUB from Debian was showing Win7 as second option for boot. Ubuntu was installed on the same partitions as Debian. (For Win7 I have 2 partitions one 100M-system reserved and one 30G; both on NTFS). I have:
Linux ubuntu 2.6.28-18-generic #60-Ubuntu SMP Fri Mar 12 04:40:52 UTC 2010 i686 GNU/Linux

CentOS 5 :: Create A Workflow For Upgrading Various Systems Using Kickstart?

Mar 18, 2011

I am trying to create a workflow for upgrading various systems using kickstart. I was hoping folks can point me in the right direction.I have a system which already has Centos installed on it. However it is a stripped down version of Centos using a custom kickstart installer. Now I would like to upgrade these systems, using an updated kickstart file spec. I would like to be able to copy over required files into a partition on the system, make a change in the grub.conf, reboot the system and expect the system to use the kickstart file and the iso file located on a partition on the system to self upgrade the entire system.The partition which holds the iso on these systems may be raided, or it may be an LVM partition.

How do I specify in the kickstart file that the location of the iso is on an LVM partition? Is this even supported? I have tried specifiying the disk like so:

< -- isolinux/ks/harddrive.cfg -- >
harddrive --partition=mapper/VolGroup00-LogVol02 --dir=/isolinux


But the installer did not seem to like it. Instead of the iso, can I put the entire tree instead? Would that work?

General :: Windows - Why Do Operating Systems Have File Size Limits

Aug 13, 2010

What limits a file to have some maximum size depending on the Operating System? I do not exactly understand this. If you have the storage space, what else can be the limitation? You should be able to store as much data as you want the way you want (even in a single file) unless you run out of storage space.

General :: Windows - Running Multiple Operating Systems On One Laptop

Apr 23, 2011

I am in the process of running some benchmark tests on a variety of RDBMS, I am testing three different client operating systems.Would it be terrible to partition the HDD and install Ubuntu, Windows 7 and Solaris 10? If I do not do this, I will likely have to re-install the O.S numerous times due to changes in the database server o.s as well. The same question goes for the server; would it drastically effect the performance to install 3 server o.s on one server?

General :: Windows - Find In-depth Information On Various File Systems?

Apr 28, 2011

Back in the old days of PC-DOS 3.1, computers are much simpler than today's. I can learn a lot of how File System works with tools like PCTools, Norton Disk Doctor, and [URL]. Have been working exclusive in corporate database application area for over a decade, my knowledge of how these stuff work is diminishing. Standard-clean OS (Windows, Linux) installation is all I can do now. And it starts to cause me many data-loss troubles, when I have to perform something that I don't have much insight, such as install and remove peer linux os or move and resize partitions.

I'm looking for books, web resources, or communities where I can educate myself on how various file system works, for which I can have in-depth answer to questions such as:

How to remove ubuntu and grub2 ? (I recently did that, but with a lot of frustration when I was not really sure what I was doing and confront with some scary error message like "Missing BootMgr" What kind of disk-partitioning operation can be performed non-destructively, and why ? What is Active partition ? Primary Parition ? Extended Partition ? How it stored on the disk. There are many free partitioning tools out there, which one is safe to used ? NTFS, Ext3, Ext4, .. What the differences ? How to choose it wisely.

Ubuntu :: Auto Map Windows Server Folder For All Users On Systems

Feb 25, 2011

I work for a school district. We are running in a Windows environment with a Windows domain. It was asked of me if I could get an Ubuntu system on our domain and running without issue, as we would like to tinker with the idea of slowly introducing Ubuntu systems to the network.I have a test system here. I added it to the domain using Likewise-Open. I have Samba installed, etc. Here's the next curve ball that I need answered.All user documents are stored in their individual shares on the same Windows server. In Windows, we use re-directed My Documents, so their My Documents actually points to \serverusersob_dole instead of C:/Documents and Settings/Bob Dole/My Documents.

How can we do this in Ubuntu? I don't care if it re-maps the home directory or creates a folder on the desktop that is linked. Either way, I want to log in to ANY Ubuntu system and blam - I have a link to \windowsserverusersmy_share. I want any user on the domain to be able to do that to any Ubuntu system and have a link to THEIR folder on the Windows server.

General :: Preventing Windows Version Of Vim From Destroying Other File Systems Permissions

Aug 30, 2010

I am currently using the windows version of gVim to edit source files on a networked drive mapped to a linux system, as well as local files created in cygwin.

The problem is that the windows version of gVim destroys the original file permissions on the respective systems. IE: Files on cygwin are defaulted to 077. When edited by the windows version of vim they are saved as 777.This problem doesn't even occur when using ms-notepad (as well as all other editors I've tried), so I am not quite sure why gVim does it.

A possible solution would be to use cygwin's gVim for everything, but that's rather cumbersome as it requires running an x11 environment to support it, and it causes some problems when running some commands from within gVim (or vim for that matter) when working on the networked drive.

Any ideas how I might be able to maintain the existing file permissions?

This morning while on a different machine the problem with cygwin did not occur. Cygwin & gVim were the same version, however the other machine is running WinXP while the machine the problem is occurring on runs Win7.

CentOS 5 Hardware :: Request For Working Xorg.conf For ATI 4xxx Systems?

Nov 10, 2010

I just set up a new CentOS 5.5 system (using the 5.5 DVD, yum updated all packages to latest) which unfortunately due to various issues and most critically availability, has an ATI-4350. The install went OK but X does not detect the card properly so it's using the slow VESA driver. I followed the instructions here [URL] to download and install the ATI driver. It appeared to be correctly installed but not used.

Display still detects my monitor and 4350 as unknown and using some "Vendor supplied driver". Yet under the "Dual Head" tab, if I would to enable it, the ATI-4350 comes up as an option, hence implying that the driver was corrected installed and the card is actually detected. I suspect it might have to do with my Xorg.conf, although trying to edit in several ways didn't make it work.

General :: Cause Any Harm To Use Dual Operating Systems Like Windows In Terms Of Losing Data?

Aug 12, 2011

I have Windows 7 working on my laptop. I have 20GB space unpartitioned. I want to install a flavor of Linux like Fedora or Ubuntu in that space, but I have heard that keeping a dual OS configuration sometimes results in losing data stored on the hard disk. I've also heard that it may sometimes cause unrecoverable problem because when Linux is loaded on hard disk it will take over the boot loader from Windows.

Is this correct? Moreover, I have 6 partitions in Windows, but if I use a Live CD for Ubuntu or Fedora to boot, then it is not showing some partitions -- sometimes it shows only 4 or 5 partitions. What might be the problem, and how to resolve it without formatting the whole hard disk and repartitioning it?

CentOS 5 :: CentOS 5.4 Hangs Just Before Desktop Loads?

My Dell poweredge server running CentOS 5.4 and booting kernel-2.6.18-164.15.1.el5.

This remains indefinitely. While the arrow is being circled, here are the results of 'getinfo.sh device'

CentOS 5 :: Udev Hangs After Upgrade To CentOS 5.4?

May 7, 2010

I have encountered the same problem as indicated in this post: "udev hang after upgrade from 5.3 to 5.4"[URL]... I'm testing the upgrade path to centos 5.4 on several virtual machines prior to upgrading our production systems. I have upgraded centos 5.2 --> centos 5.4 and centos 5.3 to centos 5.4. In both cases udev hangs after the upgrade. The following message is displayed on the console: "Starting udev: Wait timeout. Will continue in the background [FAILED]"

I found another related post: "udev hangs on boot for a long time, suspect pam_console_apply"[URL]..So, I booted by VMs using the "udevdebug" option to grub and received the same error message - "udevd-event [###]: run_program: Waiting ## seconds for output of '/sbin/pam_console_apply /dev/..."

In my /etc/ldap.conf file "bind_policy hard" is commented out. I added a line "bind_policy soft" as described in the post and my VMs booted fine. NOTE: This problem is not encountered with a fresh install of CentOS 5.4 and the "bind_policy hard" option in the /etc/ldap.conf is commented out as in the upgraded systems. What is really causing this problem and how do I get it addressed? I have a couple hundred systems to update from various releases of CentOS 5 to the latest current version 5.4. It would be nice to get this bug squashed..

Software :: Install Gcc On KDE And It Says Missing An Instal.sh File?

Jul 22, 2010

I am trying to install gcc so I can compile C++ on a Virtual linux machine I have on my pc. I went to the GNU website and downloaded gcc-g++-4.5.0.tar.gz, unzipped and un-tarred it. This left me with a folder named gcc-4.5.0 which itself contained two folders. One named gcc and another named libstdc++-v3. From trying to follow a (not very clear) guide online I created another folder in the libstdc++-v3 folder named objdir into which I copied the configre executable. I then tried to run it here and was told that I was missing an install.sh file.

found one of these from somewhere else on my machine and copied it into the libstdc++-v3 folder. Now when I try to run the configure executable from the objdir folder I get a message saying "configure: error: cannot run /bin/bash ./config.sub.Basically all I want to do is get gcc up and running so I can compile some codeWhat I have been doing so far is probably way off the mark but its as far as I could get from following stuff online.
