CentOS 5 :: Deskewing An Image
Apr 1, 2010I have install netpbm on my system because I wanted to make use of pamtilt. But when I attempt to use that command, apparently it cannot be found.

View 1 RepliesI 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

How can I create/boot CentOs 5.3 ram image?I'm looking to create a CentOs ram image that once booted will not access the hard drive.
View 3 Replies View RelatedI upgraded my system to Centos 5.2. But the system hung with 15 minutes to go on Disk 1. So I had to reboot. It completed the Upgrade without errors the second time.
But when I rebooted grub only shows the old images from Centos 4. I enter grub and ran the command "cat /boot/grub/grub.conf", whose existance I found out about reading section 39.6 of the user guide. But it returns an error "Error 15: File not found" Reluctant to proceed without understanding why this config file is not in existance. I assume I could use the command "grub>configfile/boot/grub/grub.conf" to create one from scratch, but that does not seem right. Suggested next steps?
Btw when I let Centos 4 boot is fails all over the place I assume because the system is now 5.2.
Just finished downloading the CentOS5.5 x86_64 DVD images (2 ISO's), and realize that I have almost run out of DVD-R's. First ISO is a perfect fit for the 4.7GB DVD, the second only is ~400MB. Wondering if there may be any issue if I burn the second one to a CD (which I have plenty). I guess it should be okay, but wanted to double-check.
View 2 Replies View RelatedI have 4 different servers with exactly the same hardware. I set up one of them to have a centos install with all the basic stuff I'd like running on each one. I then created an image of the harddrive with the operating system, and stored it on an external drive. I used dd to copy the external image to one of the new machines. It worked fine, everything booted up as normal and with a few tweaks everything was great. The problem is that the drive is rather large (500gb) and it takes days for dd to copy it over. I decided to try a different route, I booted to a usb (using the linux distro on the ultimate boot cd pre-loaded with gparted). There are two partitions on the external drive, a small (100mb) partition which can easily be copied over with gparted, and the larger 480+gb lvm partition.
Gparted doesn't support lvm, so I used fdisk to create a new lvm partition on the new machine, and then pvcreate/vgcreate/lvcreate to re-create the same volume groups/logical volumes that are in the image on the external harddrive. I rsync'ed all the information over from LogVol00, and made the same swap partition LogVol01 (which took WAY less time). I disconnected the hard drive and renamed the volume group to VolGroup00 (initiall I named it differently, since linux doesn't like having the volume groups named the same). I can mount the LogVol00 partition and see all the files as they should be. But when I try and boot up, it doesn't even go to grub, I just end up with a blank screen and blinking cursor. How to make the drive bootable? Alternatively, a better strategy than using dd to restore this image??
what is the best software for cloning my centos as an exact image?

But when I try building the minimal image as a test, I get lots of errors, as seen in the attached build log. There are lots of things that don't seem to work. Is this project at a state where it's not currently usable? Or do I have a problem with my system configuration? I was running at root.

I've seen some tools available for taking image backups (amanda, bacula, ...) of the O/S. I have a nas drive and want to back up the the entire disk to it (while running preferrably). Can someone recommend what tool would be best to use (free of course) and hopefully not too complex.
View 3 Replies View RelatedI have a problem with neither seems to be a problem with an image nor with firefox. I just don't see the following image with firefox (as an example): [URL] I have tried this with firefox versions 3.5.8, 3.6, 3.7a3pre in safe-mode, after clearing the cache etc. I can see the image with an other browser (e.g. opera) and also basic tools (like kview, gthumb etc) are no problem at all. My sysadmin updated the X-server for my CentOs 5.4 version without success. I am in contact with the firefox people, but no-one can reprpduce this problem. So it is likely that it is the operating system why I file this new thread.

View 3 Replies View RelatedIn order to not post into the wrong forum, I am wondering if an issue related to performing a PXE based NFS install can be posted here, or does it belong in the networking forum? Seems that I've seen both, and I've done several searches using parameters/error messages that I'm seeing and can't seem to find a post that relates.
I have results of "./getinfo.sh network", and other necessary config file info ready to post, but want to make certain on correct forum.
recommend a good image editing application for Centos?
View 3 Replies View RelatedI have a CentOS 5.5 server that has just recently been updated to 5.6 running PostgreSQL 8.4 and Drupal for an internal website. The server is also acting as a shared network storage between the Linux server and Windows desktops with Samba.
I just recently purchased a license to run Symantec Backup Exec System Restore 2010 for Linux and the only operating systems that are supported are RedHat and Suse Linux.
Does anyone know of a nice open source solution that we can use to create backup images of the server?
In the event of a server crash, we want to be able to rebuild the server via a bit-by-bit backup image.
The CentOS 5.6 is 32bit
From last few days i stuck with error in installing CentOS 5.5 ISO using USB stick, I have customized ISO from cent os tree 5.5 and update.(customization with respect to the package removing like openoffice, X-window, Gnome ...)
Here are some details
anaconda : anaconda-11.1.2.209-1.el5.centos
kernel : kernel-2.6.18-194.26.1.el5
I have a CentOS server that has all of the applications and security settings that I want. I would like to create a bootable ISO image of that server that can be installed across a wide variety of hardware platforms. What are the recommended tools for doing this with CentOS?
View 1 Replies View RelatedI have just finished installing (after hard work ) Centos 5.4 x86 configured with Snort & Snorby as frontend web, i would like to create from this installation kind of image that could fit to almost any hardware type.
View 2 Replies View RelatedBefore 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.
I just invested nearly 12 hours configuring a CCTV system using CentOS 5.5 Server and Zoneminder. I have it setup just the way I want it. I would like to make a clone image of the drive just in case disaster strikes (lightning strike, failed hard disk, etc). In the Windows PC world, I use a program called Ghost to make a mirror image of a hard disk. I power the computer down, run Ghost to make a block level clone of the drive, then power it back up. Can I assume that will work with CentOS without problem?
In the computer now is a 320GB SATA drive. One partition on it is swap, and the other is ext3. There is no raid setup on the drive. I have an identical 320GB drive I could use and keep it in the computer unplugged from the power and not spinning. That way if anything ever happens, I can power down, move the power and data cable to the new drive and power it back up. Granted, I will lose any new config and database changes, but it will be a lot better than starting back at square 1 and reconfiguring the entire OS and software.
I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

i want to setup multiple xen on a remote server in a datacenter, this is first time i am doing it, i want to know when we do it on a local machine it asks for bootable DVD to be inserted, but that can't be done on a remote server, so is there a way we can give it the path of some directory which behaves as a bootable dvd and install the os

View 1 Replies View RelatedIs there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

View 8 Replies View RelatedI'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).
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?
View 1 Replies View RelatedI 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.
When playing dvd's, vob files and wmv files, the image comes with high contrast colors ,very intense red/green/blue. very dark too. I have vlc 1.1.4 installed, using ubuntu 10.10, libdvdcss2 installed. for the rest of the video formats it seems to work fine. any ideas on what should I start debugging?

So the first image will display on the page, and when a user puts their cursor over it, then it will load image 2. When they press it, it loads image 3.
