Free kernel recovery for access software for linux

Kernel Version Monitor is a Superkaramba theme that creates a widget displaying the current version information of the Linux kernel as put forth by the kernel.org RSS feed here: http://kernel.org/kdist/rss.xml . Kernel Version Monitor uses the Tux icon from the nuoveXT icon theme found at http://nuovext.pwsp.net

Kudos and thanks to Richard "Ricardo" Szlachta for his advice on refining the aesthetics of this theme.

This is my first Superkaramba theme and a work in progress. I would love to hear comments, opinions and suggestions in order to improve this theme.

Make CD-ROM Recovery makes a bootable (El Torito) disaster recovery image (CDrec.iso), including backups of the linux system to the same CD-ROM (or CD-RW) if space permits, or to a multi-volume CD-ROM set. Otherwise, the backups can be stored on another local disk, NFS disk or (remote) tape.

After a disaster (disk crash or system intrusion) the system can be booted from the CD-ROM and one can restore the complete system as it was (at the time mkCDrec was run) with the command /etc/recovery/start-restore.sh

Disk cloning (clone-dsk.sh script) allows one to restore a disk to another disk (the destination disk does not have to be of the same size as it calculates the partition layout itself). A thrid script, restore-fs.sh, will restore only one filesystem to a partition of your choice, and the user can choose with which filesystem the partition has to be formatted.

Linux 2.2.x, 2.4.x and 2.6.x kernels are supported, and if size of the kernel is not too big a boot floppy can be made, otherwise a 2.88 Mb boot floppy will be emulated on CD-ROM.

MkCDrec supports ext2 , ext3, minix, xfs , jfs, reiserfs file systems, LVM and software RAID (multiple devices). Each file system is backed up as a compressed tar archive (including the tar log). The compress program used is the users choice (compress, gzip, bzip2, lzop,...)

But there is more: msdos, fat, vfat and ntfs mounted partitions are recognized and are saved as compressed dumps (on CD, tape, etc.)
The user has the possibility to encrypt all backups with openssl if desired (see the Config.sh configuration file for more information).

To restore your system completely just boot from the first CD-ROM made by mkCDrec and type "/etc/recovery/start-restore.sh " to restore everything from CD. Automatic Disaster Recovery and One Button Disaster Recovery are supported by mkCDrec too.
With the clone-dsk.sh script one can restore selective a disk or partitions to another free disk.

mkCDrec supports IDE (inclusive ATA), SCSI disks, hardware RAID based disks (e.g. Compaq SMART2 Disk Array), LVM and software RAID. With an El-Torito CD-ROM you can boot from an IDE or SCSI based CD-ROM drive on IA32/64, powermac and x86_64 GNU/Linux based computer systems only.

nEW uNIFIED mEMORY aCCESS (or numa for short) is a file recovery tool for the ext3/ext2 file system. It recovers deleted GIF files of less than 48kb.
Enhancements:
- This release also recovers MP3, PDF, PNG, HTML, and Java files.

Kernel Configuration Comparison (kccmp) provides a GUI for comparing two Linux kernel ".config" files.
It shows configuration variables with different values in a tabular format. It also shows configuration variables found in only one of the input configuration files.
Building:
kccmp by default requires Qt 3.x. However, by changing one line in kccmp.pro you can build against Qt 4.x. Note that the Qt 4.x build requilres libboost_regex as well.
The standard build is as easy as:
example:
% qmake
% make
Usage
% kccmp /path/to/first/.config path/to/second/.config
example:
% kccmp /usr/src/linux/.config /usr/src/linux/.config.old
Enhancements:
- This release was ported to Qt 3.x.
- The requirement for libboost_regex was removed.
- Building with either Qt 4.x or Qt 3.x is now supported.

Kaboot Linux Operating system aims to provide an operating system which you can take anywhere and has all your favourite programs on.
Kaboot operating system is avaliable as a Live CD or Live USB you can take with you anywhere.
A number of different versions are avaliable, two optimised for size or speed, one for functionality, and one science based.
All containing a host of useful programs able to boot virtually any computer (meeting the minimum requirements) from CD and
USB.Kaboot is still in active development and if you find a bug or fix, you can let me know in the forums.
Enhancements:
- A network bug was fixed.
- A few debugging utilities were added.
- Hotplugging was implemented.

Linux Kernel Monitor is a tool for monitoring and managing linuxs kernel. It has been developed for GNOME, using Glib and Gtk libraries in C language.
lkmonitor tries to offer detailed information of the characteristics of the system, as type of cpu, state of the memory or the file system registered in kernel.
lkmonitor is an open source project with information about the source code and software architecture to make easy the development of new characteristics.
Enhancements:
- IO information, kernel information, networking info, processes specific information, filesystems, modules, etc.

Kernel Mode Linux project is a technology which enables us to execute user programs in kernel mode. In Kernel Mode Linux, user programs can be executed as user processes that have the privilege level of kernel mode.
The benefit of executing user programs in kernel mode is that the user programs can access a kernel address space directly. So, for example, user programs can invoke system calls very fast because it is unnecessary to switch between a kernel mode and a user mode by using costly software interruptions or context switches.
Unlike kernel modules, user programs are executed as ordinary processes (except for their privilege level), so scheduling and paging are performed as usual.
Although it seems dangerous to let user programs access a kernel directly, safety of the kernel can be ensured, for example, by static type checking, software fault isolation, and so forth.
For proof of concept, we are developing a system which is based on the combination of Kernel Mode Linux and Typed Assembly Language, TAL. (TAL can ensure safety of programs through its type checking and the type checking can be done at machine binary level.
Version restrictions:
- User processes executed in kernel mode should obey the following limitations. Otherwise, your system will be in an undefined state. In the worst-case scenario, your system will crash.
- On IA-32, programs executed in kernel mode shouldnt modify their CS, DS, FS and SS registers.
- On AMD64, programs executed in kernel mode shouldnt modify their CS register.
- In addition, on AMD64, IA-32 binaries cannot be executed in kernel mode.
Enhancements:
- This release has been merged with the 2.6.19 Linux kernel.
