Ubuntu Installation :: Custom Server ISO - The CD On /dev/sr0 Is Not An CD?
Mar 12, 2010
What I am going to tell you has worked for the Alternative Ubuntu ISO but I would like to see if I can do this for the Server Ubuntu ISO. I need to pass along some ideas as no one else seems to have tried it this way on this forum (other have been using preseeds but I don't think this way).[URL]Copy files from the mounted ISO to my HDD: cp -rf /mnt/ubuntu/* /opt/ubuntu-server/Once the files were on my HDD, I started to edit files that would help using a special preseed I wanted to configureI changed directories to /opt/ubuntu-server/preseed/ and created a file called test.seedI edited the test.seed file with the example found here:[URL]Saved it and changed directories to /opt/ubuntu-server/isolinux/Started the edit the text.cfg (holds the labels for installing ubuntu)Here is what I appended to the end of the file:
---
label test-install
menu label ^Install Test Ubuntu

Just spent three whole days barking up the wrong tree, solving Fedora 11 and Fedora 12 boot failures because the correct hypothesis was illogical: installation did not update/modify the initrd.
The first couple of times I installed Fedora 11 on the HighPoint Technologies RocketRaid 2640x4, the installation inserted my "custom" driver module (rr26xx) into the initrd, permanently, so that the system booted off the controller card for which the custom driver was inserted. (I yelled about this success in this thread: [url]
My most recent installs of BOTH F11 and F12 on the RocketRaid failed to properly set up the boot. It turns out that the "rr2640" module I "slipstreamed" into the installation process was *NOT* permanently added to the initrd by anaconda. (F12 gave me "no root device found boot has failed, sleeping forever", on boot; F11 hung also, without such error, I presume, during the init script execution). Because of limited resources and time, I only know for sure the module was missing from the F11 initrd, and am ASSUMING the same was the case with F12.
The only difference between the successful installs and the ones with failed boot is that the successful installs were made on a single-drive (JBOD) mode on the controller; whereas, the failed ones were placed on RAID 5. But, AFAIK, the created logical device for the card is "/dev/sda", in both cases, and the kernel can not distinguish between the two cases (or can it?). Thus, the inconsistency cost me a lot of time, and is still inexplicable to me.
Question: What is the best way to deal with custom drivers, today? There are custom spins, and many tools, like isomaster. Stupid question: Is there a way to modify the initrd inside an installer ISO -- be it for CD/DVD/USBboot drive -- beefing the init RAM disk with whatever modules you'd like, for the boot process (using, say, isomaster)?
And what makes anaconda understand that a module must be added to the initrd ? How can one force anaconda to do so?
How does moving to dracut as the initrd tool affect any/all of the above?

I have a little script that lives on a samba server, which I want to be run at boot on all of about a dozen Lubuntu 10.04 desktops? How do I go about doing this? IIRC there's somewhere you can put your own boot scripts, but I forgot where. Mount the samba share with fstab and put a symlink to the script is what I'm thinking. Currently on one machine I have the relevant line in /etc/fstab as
Code:
//192.168.10.8/wpkg /media/wpkg smbfs rw,username=wpkg,password=password 0 0
I'm not sure if that will mount it at boot or if I'm missing anything. (There's nothing private in that share so the password in plaintext doesn't matter).The script itself does things like adds a user if it's not present, installs and updates software - basically anything I want done to all the computers, I just put it in the script.

I've created a USB startup disk under Ubuntu 10.04 lucid (Live CD), Ive selected the option to save system settings to the flashdrive with about 200MB usage, now that ive configured and customized the opperating system (on the flashdrive) I want to create a ISO from that flashdrive installation.
Once the ISO is created, I want to burn it, boot off the CD then create another startup disk but this time setting "Discard on shutdown" so no settings or files can be saved to the flashdrive, but my custom setup remains. "its for an internet cafe setup".
How do i recreate an ISO from the USB startup disk?

I'm a bit of a noob at Ubuntu (I can use the terminal and stuff though), and I want to know if I can specify a custom server for downloading updates and packages.I am running Ubuntu 10.04 and I want to use Adam Internet's FileArena server: [URL]... It's not listed in the list of servers and I want to know how I can add it or use it(because downloads from there don't count towards my download allowance).

I'm currently running 10.10 64-bit version, with the current Nvidia driver installed for my 9600GT graphics card (2x DVI-out). With the card, I am running one VGA monitor and one HDMI TV (both using adaptors). I am running the screens in TwinView, using X Server Settings. My problem is, with the resolution available for my HDTV. In both Windows (XP and 7) and Ubuntu, the current Nvidia drivers all report the native resolution as 1920x1080, this however, is incorrect; the reported native resolution of the TV (according to the manufacturer) is 1280x720; but even set to that, there are still a few pixels missing outside of the screen.
In Windows, the Nvidia Control Panel lets me manually resize the desktop area on the HDTV, to a slightly smaller resolution than 1280x720, so that all pixels are within the viewing area. Is there anyway to do this with Ubuntu, using the current Nvidia driver? I cannot seem to find a way, using Nvidia X Server Settings.

I have builded my kernel through wiki manual, BUT, the kernel-headers rpm-package has not been builded. Now i have only two packages: kernel and kernel-devel. Is that ok? (i think, that it is not ok, because when i build the same version of kernel on x86_64 platform, after rpmbuild command i have kernel, kernel-devel and kernel-headers packages) My CentOS version is 5.2; platform i686; kernel, kernel-headers, kernel-devel packages 2.6.18-92.el5.

At work, we use custom Ubuntu installations, I create them by plugging the new hard drive to my computer and running some installation scripts, basically, these scripts debootstrap the hard drive and later install some additional packages and files. It works great for our needs.
But now, I think a CD or USB installation method could be a better option, and would like to get some advice on how and what tools could be of use for this.
I'm reading the Install CD Customization guide at [url]...DCustomization, and I think I can use it, but would have to remove a lot of packages (we use only the ones supplied by the "normal" debootstrap process and some other packages, mainly the X server and optionally FluxBox).
Are there other alternatives? Is there a tool that I could execute inside one of the already created systems that would allow me to package the whole system as an installation CD? Remastersys perhaps?

I am trying to get custom options to work.
This is my Dhcpd.conf file
This shows that I have 3 custom option in RED.
Now when I try to pull an Ip from the 96.63.0.0/24 subnet I do not see the options in the DHCPACK from the server. The client gets an IP 96.63.0.12 but no options are present in the DHCPACK or any other DHCP transaction. I have confirmed this trhough tcpdumps on the server and client.
The server version I am using is:
The version of the DHCP server is :
Internet Systems Consortium DHCP Server V3.0.6-Fedora

We're using Munin for trend analysis purposes, but would like to use it to generate custom reports. One way I envision this is:
* The report is created as a web-page on the munin server, such as [URL]
* The layout of the report is customized based on the project
* The report will be triggered by a cron-job, and I will be notified by email when the report is completed
Does anyone know if this type of script/job allready exists?

When you install Ubuntu, you will typically install a complete desktop environment. It is also possible to install a minimal set of software (just enough to boot your machine) and then manually select the precise software applications to install. Such a "custom" install is usually favoured by server administrators, who prefer to keep only the software they absolutely need on the server.
I have never personally noticed any sections in the install to allow you to do a custom minimal install, is this possible in Lucid?If so how, or do I need to download just a mini install iso?

I just installed Edubuntu 10.04 and Its crashed on me twice already (by comparison, I lost 8.10 only four or five times during the entire year and a half I was using it). The monitor goes blank, then produces odd color schemes and then loses the signal altogether, eventually rebooting. It seems to be somehow connected to a non-existent /etc/gdm/custom.conf file. Here's the output from syslog:
May 5 21:16:44 rishon kernel: [ 9036.624038] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

I've recently setup a custom home server running openSUSE 11.3 64-bit in terminal mode. I've since successfully setup and configured it to act as an iSCSI target using the iscsitarget package and the corresponding kernel module, along with the YaST module for the configuration. Prior to setting up my hard drive accordingly, however, I noticed that when I ran 'zypper up' in a terminal I got the following:
Code:
pph-server:~ # zypper up
Loading repository data...
Reading installed packages...
[Code]....
At the time I accepted, and found later that it removed the setup I had, meaning I had to start over. However when I ran YaST in a terminal it then wanted to re-install the iscsitarget package, which subsequently removed the tgt package, and so this continued for a bit. (Thankfully no actual data was stored on the target at this stage .) For the time being I've locked the iscsitarget package and the kernel module to prevent zypper from wanting to remove it and install tgt instead since I now have my target working as I want.
The question I have is why zypper was trying to remove iscsitarget and install tgt, and yet the corresponding YaST module was wanting to do the opposite. Is tgt considered a better option by the openSUSE developers, in some way, for setting up an iSCSI target? Is iscsitarget development/availability being ceased by them in favour of tgt? Is there something else I'm missing? Neither of these packages seems old to me: the latest version of iscsitarget was released on SourceForge last July, while tgt was only updated this month.

Slapd is up and running perfectly well, and I can add and remove entries without a problem. My OS is the Ubuntu based Mint.
So I was hoping for someone to give me a nudge in the right direction for doing this without a slapd.conf file, or directions for how to force slapd to pay attention to a slapd.conf file whose location I specify.
I've tried messing around with /etc/ldap/ldap.conf to no avail, I've tried just putting in a custom slapd.conf file but slapd doesn't pay attention to it.
And to the best of my knowledge I can't find anything written on this specific topic. I can find plenty on slapd.conf's, but that's just taunting me considering I don't even have it on my system.

im not very educated in amd processors, but i think that they are all 64-bit processors.
i downloaded the amd ubuntu 9.10 into my computer, and used the usb maker utility in the system menu. i put in in my new pc (it was given to me), and i tell it to boot into the usb.
then i get this. i am posting a pic.
sorry about the sideways pic. i took it with my phone.
anyway, i get the syslinux boot shell script thingy. i have tried lots of things. linux, vmlinuz, lots of other things i found online. so what im wondering is the exact name of the kernel in ubuntu 9.10 amd version.

Having spent weeks perfecting my Ubuntu the way I like it, I was wondering if there is a way of preserving it as a either a liveCD or USB flash drive, with a view of using it on other PC's activated upon start up?
Possibly (under the USB option) with the option of launching from the flash drive itself, or installing onto a PC's hard drive.So, in essence, it would be a liveCD but custom made to reflect the way my Ubuntu looks and feels now? Is there any easy-to-use software available to perform such a task?

What are the best ways to make the kernel using git, and localmodinfo. and optimizing the kernel the best way on a laptop I have, which is a desktop laptop, so it is never really unplugged. Has a core 2 duo 2.53Ghz, 4GB DDR3 RAM, and an ATI HD 3870 GPU.so what things other than the obvious core 2 cpu type when making the kernel. It's on Ubuntu 11.04 64 bit. I also want to create it with the local mod info. and Also create this into a .deb package so it may be saved.
