I am trying to replace just the kernel (no modules) for my default kernel on FC 11. I use the default .config file and just change a few things and then run the make command. After I replace the kernel and reboot the system the password comes up for the encrypted filesystem and it does not take my password for some reason. what I need to do to get this working?

When I only change a driver file manually, for example /newkernel/linux-source-.6.32/drivers/gpu/drm/i915_drv.h, do I need to run "make config" or similar like "make menuconfig" or can I just skip? I mean these steps:
1.) apt-get install linux-source-2.6.32
2.) mkdir ~/newkernel/
3.) cp /usr/src/linux-source-2.6.32.tar.bz2 ~/newkernel/
4.) cd /newkernel/
5.) tar xjf linux-source-2.6.32.tar.bz2
6.) cd linux-source-2.6.32
7.) cp /boot/config-$(uname -r) ./.config yes "" | make oldconfig
8.) change the driver file /newkernel/linux-source-2.6.32/drivers/gpu/drm/i915_drv.h manually
8.) make-kpkg clean
9.) make-kpkg --rootcmd fakeroot --initrd --revision=custom.001 kernel_image kernel_headers

Is this way OK or do I miss something?
I need a webserver (LAMP) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole file system encrypted (#4).The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4:Can I encrypt all of the file system and still access the webserver (using a browser) or will GRUB ask me for a password?If encrypting all of the file system is not an option, can I encrypt only /home and /var/www? Will Apache/PHP be able to use files in /home or /var/www without asking for a password or mounting these partitions manually?
View 2 Replies View Relatedi installed Fedora13 a couple of days ago and also activated the encryption of the hdd. But after updating my kernel yesterday, my PC doesn't boot with the new kernel. Choosing the old one still works, so I have still acces to my Files. But how can I use the new kernel? Or how can i completely and forever decrypt my HDD? The whole hdd is encrypted, so the boot and the home stuff isn't accesible without the key. Thats pretty depressing because I felt really intelligent when enabling the encryption
View 2 Replies View RelatedI'm a long time user of Debian, but I'm having trouble with my partitioning process. Here is where I currently stand:
I am installing the latest Wheezy build. I am trying to install debian with an encrypted LVM that spans two hard disks.
My partitioning layout is as:
1. /home
2. /root
3. swap
4. /boot
I then added partitions 1, 2 and 3 to a physical volume group. I then took that physical volume group and added it to a logical volume. Then I encrypted the logical volume, leaving the /boot partition untouched. I was under the assumption that the only partition the system needed free to reach the loading of the LVM is the /boot partition, as it holds the files necessary for booting. But when I attempt to finalize the disk, it gives an error stating, "No root file system detected". That would be an issue as it is currently sitting inside the encrypted LV. Am I wrong in including the root partition in the encrypted LV?
What is the best way of having as little of my file system non-encrypted as possible while still allowing a proper boot?
Centos 5.3 includes Ext4 and improved support for encrypted file systems but it appears to be aimed at laptop/desktop systems, in that a password must be entered at boot time.
Is it possible to have a server with an encrypted root file system boot up without entering a password?
Mandos will do it...
http://wiki.fukt.bsnet.se/wiki/Mandos
...by serving up the password from another server...
http://packages.debian.org/squeeze/mandos
...to a client loaded into the initial RAM disk environment...
http://packages.debian.org/squeeze/mandos-client
...but it's not available on CentOS, and is only in Debian unstable.
Is there a similar (or any) solution for CentOS?
In particular, I'm envisaging encrypted virtual machines being served passwords from their virtual host.
Alternatively, the data that *really* needs to be protected could be encrypted while the system core remains unencrypted. But then the keys to decrypt the file system must be stored in the unencrypted portion, so this is not an effective method.

it's possible to compile the 2.6.37 kernel patched with the autogroup patch on a Slackware 13.1 system running 2.6.33.4-smp with 2.6.33.4 headers? I just compiled and installed the 2.6.37-autogroup kernel from AUR on my ARCH setup and I like it especially when using firefox with lots of tabs open and other background apps also running. I did notice a speed and smothness difference in my ARCH testing setup with this kernel patch and I can get same results in 13.1??
View 1 Replies View RelatedI am using Opensuse 11.2 on an HP Pavilion laptop. The internal wireless (Broadcom device) quit on me - It is no longer detected at boot so I assume it is dead. No problem since I have a D_Link USB adaptor (DWL-G132). To get it working however I need ndiswrapper. I then installed ndiswrapper 1.55 and the user interface supplied with Opensuse. Problem1- The interface says "The program 'kernel-headers' is missing on your system".
I have checked with Yast and the kernel-headers are installed. Problem2- I have downloaded ndiswrapper 1.55 from Sourceforge.net to attempt the traditional installation method. The 'make' command returns the following message: "Cannot find kernel version in /lib/modules/2.6.31.8-0.1-desktop/build, is it configured?."

I thought I would give some instructions on how I compile my kernels. My long-time windows user parts trader recently asked me how to compile a kernel on Fedora. He was confused with all the tutorials requiring you to build an RPM, so I showed him how I do it, the standard/easy/lazy way. Before I start, here are a couple things I assume. I assume you are a Fedora user and that you are NOT in text mode, but in GNOME. I also assume you realize that this can take up to SIX HOURS on an old Pentium 3 1.3Ghz. Remember that some proprietary drivers as well as some free ones are not included in the kernel, so make sure you don't delete your existing one.
First get the dependencies you need.
su -c "yum -y install gcc ncurses-devel"
Next get the kernel source. I use 2.6.33.3 as an example. To download it, click here.Extract it by right-clicking on the file and then choosing extract here. This will take about five minutes. Now open a terminal, become root, and cd to the directory linux-2.6.33.3. It is important to cd here and not to the kernel directory inside of there, even though make has an extra variable that specifies there.
Now we need to configure the kernel before we build it with make O=kernel menuconfig. It will take a couple minutes to set up, then you will be presented with a cheap psuedo-gui in your terminal. Just select exit and yes to save your config. You usually don't need to change anything here.
Ready to compile and install? Remember this can take up to six hours, and your machine may become VERY slow. It is not recommended that you attempt to use your machine with this in progress. OK then. As root, in the same directory, type:
make O=kernel && make O=kernel modules_install install. This will compile the kernel and install the kernel and it's modules. Done? Now change the kernel and initrd in your bootloader to match the new kernel. If you ever want to reuse the same source code folder, use make mrproper to clean things up and build it again.
I am very much a Newbie to Linux/Fedora. Just installed Fedora 10, but having some problems with hardware driver recognition, particularly a wireless network PCI card. ndiswrapper is looking for a kernel in usr/src/kernels, which doesn't exist.In Fedora, is it necessary to compile a kernel? Looking through the FAQ at kernelnewbies, states to extract the kernel to a Linux directory, in usr/src, which also doesn't exist.
