CentOS 5 :: Testing Installation - Image File Not Running
Jul 12, 2009
Before installing Centos, I downloaded an image file and burned it to CD using InfraRecorder. It starts to run but does not complete. My machine is a new Intel Q6600 Core 2 Quad CPU with 4G of RAM. It is a 64-bit machine, and I used the 64-bit image. After Centos (which I tried first) failed, I then tried (using the same burning software):
o Slackware
o UBuntu
o gNewSense
o Knoppix
o Debian
o Fedora
o Suse
o BSD
o Solaris
0 puppy Linux
Most failed similarly to Centos. Knoppix worked fully several times, but I was not enthusiastic about installing it, and eventually (on the 5th iteration), it started to fail in a way similar to Centos, and continues so. Solaris and PuppyLinux worked. Those that failed, failed while attempting to start the 4 CPUs. Solaris and Knoppix (when it worked) succeeded in starting all 4 cpus and I could see the messages.
How to communicate what's happening during a failed boot? Finally, I hit upon the idea of photographing the screen during the failing part of the boot; the file is attached. The photo shows the screen just before it blanks, and the BIOS resets for another try. Please let me know if I can collect any other information. I would like to use Centos as a dual boot on my shiny new machine.

As I understand it creating an image of a Linux system makes an exact copy of the OS and any user files/configurations/programs etc. What i would love to do is create an image of my work PC and install it at home on my desktop. Can someone briefly explain the process of creating and installing images of Linux systems?
Home OS - windows Want - An image file that can be executed in a virtual machine(VMPlayer or VirtualBox) or booted directly on my home PC.

I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer
to do a text-based install.
The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.

I am trying to upload some pics on my Facebook account using Firefox. When I click on Facebook's file upload icon, Firefox bring up a 'File Upload' window. I noticed that smaller image file is previewed on the lower right hand corner, while bigger image file is not. Is there anyway I can change this behavior or maybe change what Firefox is using to browse my files?

I'm trying to install Squeeze onto a new DELL Vostro 1520 laptop. The Windows Device Manager says it is Realtek PCIe GBE Family Controller.
During the network card detection phase, it prompts to install missing firmware file rtl8168d-1.fw from removable media. I understand that this is a non-free blob removed from kernel v2.6.32.

Does anybody know how to or even if it's possible to create an ISO image (a snapshot, if you will) of an entire volume on a Linux box so that I can use that ISO to burn to a CD use in the future for creating an identical configuation on another box (which would have the same exact hardware)? It is to my understanding that I'd have to first create the ISO file of the entire system and then burn it to a CD and somehow mount it onto the hard drive of the identical-system-to-be.
I'm thinking that I'd have to use the "mkisofs" command but I'm not sure exactly how to do this. P.S. I do not want to use any 3rd party applications.

I've got a desktop "konsole" shortcut that works great, it has a "konsole" icon on it that fits well.
I've copied this desktop shortcut to a taskbar shortcut (via drag'n drop).
The result is a usable shortcut, but with a wrong icon image.
I've reproduced the problem three times for different apps and obtained three times the same icon (but the shortcut is however good).
If I open the configuration popup, it displays the correct icon ...
Indeed, I found a way to change the icon : I must modify the icon of the filetype associated with "desktop" filetype ... but after a reboot, all icons will changed Strange isn't it ? have a look of the screenshot

I have a system built and running in exactly the basic configuration I want, with my recompiled kernel, extra packages, special drivers, everything works, life is good. What I want to do is take this exact setup and create an image I can copy onto a bootable USB stick. Is there a way to essentially take the contents of my hard drive and copy that onto a USB stick and then boot directly from that? The use case behind this is that I am building an embedded system of which I may have hundreds of boxes with identical hardware and software configurations. Instead of hard drives, I am going to use USB sticks for cost efficiency and maintenance. My idea is that when it's time to upgrade, I could just image a hundred new sticks and go out and swap them.
My issue is that a standard LiveCD install gets me maybe 25% of the way to a finished system. I need to recompile the kernel for realtime support with my CPU, add some fidgety drivers for some specific hardware, and install a whole bunch of additional packages. I suppose I could create a makefile(s) to replicate all the manual steps of the buildout but that seems like a lot of unnecessary complexity IF I can just image that running system as it is.

I have a CentOS5 server with a 1tb hard drive.There is only 80gb of data on that huge drive and now I want to make a bare metal recovery backup using AcronisMy question is, how can I estimate the amount of time the backup will take and the size of the image file? Is it based on the size of my drive or is it based on the amount of data on the drive?

I'm trying to test my harddrive, but no results are coming through - running the following I hear the drive, and all reads to be well:
Code:
[stuart8.5@mepis1 Documents]$ sudo smartctl -t long /dev/sda
smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen
Home page is http://smartmontools.sourceforge.net/
[Code].....
Running this command on an older PC, I know that the "Remaining" percentage should decrease over time till expiration (83 mins here). Additionally, I have noticed that the 'complete time' of 16:31 is wrong, behind the actual time by 3/4 hours, but whether this is factor or not I don't know. Short testing is the same.

I am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.

Can I install ubuntu to an image file? I am using GRUB to boot my live cd, so is there a way to trick the installer into picking up an image file as another hard disk, like it is in wubi? (I am using mac)

The DVD disk is from LinuxFormatMagazine, and PCLOS is the ISO that boots. It has 10.10 on it also, but that isn't the ISO that loads by default. Do I have to transfer the 10.10 file, and burn it to a new ISO? Or can I run or install it from its' current file type on the DVD?

When I look in /var/cache/apt/archives/, I see packages I recognize that I downloaded. But, I also see packages that I know I did not download, but rather were part of the initial installation of the image iso file on the CD. For example, the package for Abiword is in there. I would like to know which packages in this directory I installed, and which were part of the initial installation.
How do I know which packages are part of the installation from the image iso file on the CD? Once I know that, I would make a copy of all the other packages in this folder onto a DVD, so if I ever need to reinstall Ubuntu 9.10 I will know which packages to install over and above those part of the initial installation off the iso CD.

I have just acquired a new co-hosted server and want to get squirrelmail up and running for all domains.
I only have ssh access and have installed squirrelmail using "yum install squirrelmail" which seemed to go ok but when I try to invoke it on any domain produces a blank page.
I have looked at various installation tutorials but all seem to take it from initial compilation etc which I haven't had to do. IMAP is already set up.

I am trying to search a tool for testing multicast. Currently, 'yum search multicast' yields nothing. I saw mcsender and mctest in google but they seem not to be supported in CentOS. Do you know any tool that can test multicast?

I put a script into the post installation of kickstart and the log showed that the yum that is started in the script had to wait for yum to finish. I understand I can (and will) put this package in the packages section, but isn't it bad that yum is still finishing up when the post installation is initialized? Has anyone else noticed this?

I have Centos 5. I enabled the EL repos so I could upgrade the php to the latest, and now there are upgrades that yum is not letting me get. I have a Virtualmin VPN plugin that needs Virtualmin to be updated to 5.10, but it seems when I updated PHP with the EL repos Yum is now reducing my available packages. Here are some outputs. with some things removed for length.

Alright, so I installed the c5-testing versions of httpd, php, and mysql, since my server is used for other daemons primarily and these aren't used as production servers I decided to test the bleeding edge versions of these, report any bugs I find, etc. The problem is, since I updated httpd and mysqld they no longer start up at boot. I tried using chkconfig --add with both of them, but both their init.d scripts have - for levels, so I did not assign any levels. They still do not start up at boot. [URL]

We are going through the motions of testing the backup and restore configurations of our postgres database. One idea was testing the viability of the dump file. Does anyone know of a way of testing the dump file to determine if there is any corruption in it

I hoped to use php-5.2 while keeping close the the centos packages (no external repositories).So I tried the packages from http://dev.centos.org/centos/5/testing/i386/RPMS/ .These packages seem to be compiled without mime-magic support (--without-mime-magic).The previous stable php-5.1.6 packages had this mime-magic support enabled.

I am a developer, not a network admin - sorry if this ia dumb question. I need to test an application on CentOS 55 64 bit. The instalation went fine and initially I let DHCP work its magic. The router IP address ia 192.168.0.1 and all other VM's I have are granted dynamic ip address on this range (i.e. 192.168.0.x). However, the CentOS vm got an IP address that looks like it belongs on a different subnet :192.168.1.1
The VM (vmware desktop) network setting for this VM uses "Bridged: Connected directly to the physical network". I can ping the host (Windows 7 64 bit) and the host can ping it (it been the VM) - but no other computer on the network can see it. To make things easier, I changed the network configuration to use a static IP address. Here are my configuration files:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes
TYPE=Ethernet

I've been working on the setup of a FTP server on my Debian system for the whole afternoon. But I can't get it straight! Normally I get it working in just a second, but it's been a while I guess.
I installed only proftpd-basic and it's default dependencies. Should be enough right?
My configuration files are as follows:
I created the user zeitgeist, gave it a password, group and a homedir. Group of the user is nogroup and the homedir is correct with the 755 permission. My port 21 for FTP is open I tested it with nmap -p 21 [ip-address].
My Filezilla client tells me that at first he is connecting, then the connection is established, And then the connection is closed by server.

Using the following software:
Ubuntu Server 8.04
SquirrelMail 1.4.13
Postfix 2.5.1
Courier 0.59.0 (Courier-IMAP 4.3.1)
Apache2 2.2.8
I've installed a mail server per the instructions at [url].
Neither POP nor IMAP test successfully with the user that I just added after following the setup instructions.
This doesn't make any sense. I added the user to the mysql database:
Code:
And after I did that, I ran the postfix reload command. If I try to log in as firstuser@mydomain.com, which is the user I created during the setup and configuration process, it works fine.
I checked the virtual mail account's home folder, and under the mydomain.com folder, I only see a folder for firstuser. I'd create one for testuser manually, but I don't know if that'll work since it seems to contain a particular folder structure of its own.
Is there some other command that I have to run? I don't recall having to do anything additional when setting up firstuser.
