CentOS 5 :: Information About Customizing ISO Images
Nov 4, 2009
I know there are similar topics about this that have been posted, but the information I need I cannot find. Im in a situation where I have two new HP DL360 G6 servers, both have a HP Smart Array B110i Sata Raid Controller. Since the raid controller is so new CentOS 5.3/5.4 and RHEL 5.3/5.4 do not have support built into the installer.I do have a driver for the raid controller which I have used and successfully installed CentOS 5.3 on one of the systems.The reason I need to customize an ISO is because I need the raid controller driver as part of the installation disc. As these systems are servers and are going to be deployed remotely I will not have physical access to these systems if they need to be rebuilt. I also have to build machines remotely as well using iLO (having a floppy image or usb image of the drivers does not work through iLO).
The installation rpm's can be as is, I do not need to make any changes there. I just need to make sure that the raid controller driver is loaded into memory from the media rather than another media source, before the installer kicks in.
I am just customizing CentOS and would like to change "Welcome message[image is attached] to something that I wanted. I went trough the anaconda source rpm and found that OS name is being picked by %s and not sure what %s refers to or where is that variable it pointing to.
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
I tried to load CentOS on another system last night. I used the same cd I used on my previous system and now when I run the test it fails and wont load the os. I tried to burn another set and same results. I there a know good mirror I can try and re-download the ISO again to see what going on. I loaded xp just to see if it was my drive and xp and and livecd fo CentOS works fine. So I dont think its a cd issue. I used the same drive to burn all the cd too. I tried the gui and the text version.
On the text version I get some error about mounting the cd and tty2 or something like that. This happens after I enter in all my disk/networking info and it is trying to do the load. The gui version when it starts up seems OK then it says starting x server and then I get a blank screen with a big X cursor but never get the screen to enter in info. No I have not tried the cd on another system yet as I don't have one that I can risk wiping out. But if I have to I will get an old drive and put it in my laptop and see if it boots.
I recently migrated to a newer server running centos5 and cpanel
I have imagemagick installed
I installed freetype as well
Most images display fine on web pages for accounts on the server, however, .gif images do not display.All I get is an image placeholder.
.png are fine .jpg are fine
I have not tested all the possible varieties of images, but .gif I know is not displaying.I am sure its some kind of RPM I am missing or a configuration problem.
What is the difference between the boot.iso and netinstall.iso images? I've looked at the wiki and done some Googling, but haven't found a good answer yet. I know it is probably going to be something obvious, but in the context of installing a Xen fully virtualised guest there doesn't seem to be much difference. After booting both ask for the location of the install tree and proceed happily.
I am trying to get my head around my new server. I am using CENTOS 5.4 x86_64 with 300GB harddrive.
The 300 GB been partitioned with the following:
Device Size Used Available Percent Used Mount Point /dev/md0 99M 18M 77M 19% /boot /dev/md1 16G 8.7G 5.8G 61% / /dev/md2 246G 40G 194G 18% /home /dev/md3 4.8G 1.6G 3.0G 35% /var /usr/tmpDSK 3.9G 432M 3.3G 12% /tmp
I have increased teh tmpDSK as it was getting full very quickly. My question is, what are these md0; md1, md2 and md3 are they harddrive partitions and as md1 is getting full will that have an impact on my sites.
One of our devices running CentOS 5--an 8e6 Technologies Enterprise Reporter network appliance--has started displaying the following three messages repeatedly, though not continuously.Best as I can tell, hard drive four may be experiencing sector errors.(The messages do differ slightly at times. For example, 16384 may instead read 49152 or 12285, and the two strings of colon-separated hexadecimal digits may also vary in content.)Other than these messages, the device seems to be running fine. Its internal diagnostics indicate no problems.I will, of course, call 8e6 Techonologies tech support. But, prior to that, I'd like to do some troubleshooting on my own. What other troubleshooting techniques may I employ to gather more information?
I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.
using the update maneger to update on ubuntu new linux images available 2.6.31-17 generic and after the download is complete both images exist in the grub menu should i remove them ? or just remove them from the boot menu ? and if so how could i do each.
When I attempt to add software i get the following error:
Unable to Retrieve Software Information
This could be caused by not having available connection.
Cannot find a valid baseurl for repo: addons
To get my browser to work properly, I have to specify a proxy (manual) and use the IP address of our proxy server. After this, I'm able to get out through the internet using my browser. Not sure why I fail to get software updates though. I used the same setting in Proxy - Control Center. Repository Manager show's CentOS-5 - Addons mirror list as :
I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.
Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data
I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.
I'm trying to install centos 5.3 as part of AsteriskNow 1.5 on a SuperMicro server with main board type X5DA8 The anaconda fails with the following text visible:
[Code]....
Other terminals (F3 and F4) don't appear to have any interesting information on why it barfed. I tried it with a text install too, much the same result. I get this error with other Centos 5.n based Asterisk and GUI bundled mini distors too, specifically TrixBox
i've configured my laptop so i can use my domain account (active directory win 2003 DC) to logon to my machine. Now i'd like to browse and mount shares etc using my logon information. Now when i connect to a share with nautilus it tells me 'guest' can't log in and i need to re-enter my user info. This is a real pain since our passwords change often. Is there some way i can use PAM to authenticate? I've searched everywhere, but you only find info about the other way round (win->linux).
I'm trying to write a program which would get information from a webpage and display the information on my desktop sort of like a widget. I kind of remember there being something like this already made, but for the life of me I can't remember what it's calledDoes anyone know?
I have configured the proxy server. I want to observer users's download information. What should I need to do? Shall I install squint? what is the process? How do I monitor the users?
i wanted to learn linux, so i just installed Centos on a thinkpad x200. my wireless will not work. when i try to activate it i get this error:
Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory SIOCSIFFLAGS: No such file or directory # lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.
I have 2 network cards eth0 and eth1, for eth0 i set a manual MACADDR in network scripts. Ok so every time i boot, if the cable is plugged in, my eth0 fails to mount or i don't know.. i get this after bood when i type ifoncifg eth0 (eth0: error fetching interface information:Device not found). So i have to unplug the cable when i boot, then plug it in and do a service network restart.
i want to resolve the above error. I'm using systemimager to autoinstall system images on pc's connected in lan. while doing this i got the error No DHCPOFFERS received. Also at the time of booting my pc it shows the message No dhcp and/or proxyDHCP offers recieved. But i've started the dhcpd deamon on my pc. Also the systemimager rsync deamon is running. The two pc's are also connected in lan properly.
Still while autoinstalling the image on client it fails showing the error message... No DHCPOFFERS recieved. what do i do in order to make my autoinstall work properly? How do i come to know whether the dhcp server is running or not? What will be the exact problem in autoinstalling?
I decided I would try to custimize Fedora to my liking (which proved to be overwhelming). I installed Compiz-fusion and enabled "wobbly windows", which forced me to disable "snapping windows". After doing that, I rebooted to enable the effects and it starts up to a command line.I pressed CTRL+ALT+F2, logged in and ran "rm -rf .gnome .gnome2 .gconf .gconfd .metacity" which I was told would reset my gnome shell, which it didn't. I know Compiz Fusion caused this crash, how can I revert back or at least get my GUI back.
I have been using Fedora 12/13 for last 6 months or so but still I never tried my hands with the customization of its desktop and its kernel which is the beauty of Linux so I want some links or guidelines about how to start doing something meaningful with Fedora.
I just want to know weather it is possible by some means to set different preferences for the two desktops that are available in ubuntu?? E.g.: different backgrounds, shortcuts etc...
So, in the system preferences there is a setting for the laptop touchpad. I never use it and want it deactivated. Unchecking the box and setting the program as a startup app isn't doing it. So how do i go about it? Correct me if i'm wrong, but i'm thinking the best way is gonna be to edit the startup command for the app from:
command: gsynaptics to command: gsynaptics + "whatever the commands would be to tab to the first item and hit space" I have NO idea what that command would be or if it's possible.
In my menu bar under Places, I could see my Windows partitions being displayed as 20 GB Filesystem and 25 GB Filesystem which are basically C drive and D drive respectively. Is there any way I could change the way the partitions are displayed under the Places menu. I want it to be displayed as C Drive and D drive instead of 20 GB, etc.
