Free memtest86 software for linux

The mkCDrec utilities are optional for mkCDrec itself, but are an added value for rescue and recovery purposes.

The utilities are staticly compiled and include parted, memtest, partimage, gpart, and recover. Memtest86 is also available for memory testing.

To improve the added value of your recovery/rescue CD-ROM. You will notice that links from mkCDrec CD-ROM are foreseen to the /cdrom/utilities part of the CD-ROM and that man pages of these tools are already available within mkCDrec main toolset.

Without installing the utilities you cannot use them (obvious), but it will not break any other functionality of the mkCDrec tools. Therefore, a full restore remains possible (and disk cloning too), but you will not be able to resize a partition afterwards to name something.

Most of these utilities were compiled as static binaries, therefore, you can use those tools seperately too. If you know any tool which could useful to be included, please let me know... Since mkCDrec_utils_v0.5.7 you will notice that mkCDrec will use isolinux to boot from the CD-ROM instead of using syslinux floppy boot emulation.

But, this will only work if you use mkCDrec_v0.5.7 (or higher) as isolinux was first introduced in v0.5.7.

Parted

The famous Partition Editor of GNU software. The User Manual of parted is already part of mkCDrec.

Memtest

An excellent memory testing tool.

Partition Image

A tool to make/restore partition of msdos/vfat/ext2/reiserfs file systems. The primary purpose to include this tool is to allow a restore of old partition images made by this tool.

Gpart

Guess partition does what it implies. It can even recover destroyed partition tables, and therefore, maybe preventing a full restore. Useful in case if you do not make a mkcdrec on a regular basis.

Recover

An excellent tool to edit an EXT2 file system to recover lost files.

e2salvage

e2salvage is a utility which tries to recover a data from damaged ext2 partition. It may be used when e2fsck does not recover the broken ext2 filesystem. Before trying this tool read the man page (man e2salvage).

ext2resize

ext2resize, ext2prepare and ext2online are useful tools. ext2resize can increase (or decrease) the size of an unmounted ext2 filesystem. Be aware for ext2online one need a kernel patch (not likely installed). By the way, ext2resize does work too on an Ext3 filesystem! Be aware, one needs to apply S. Tweedies kernel patch (ext3) and an updated ext2 filesystem e2fprogs-1.20 or higher (which are ext3 aware). Last 2 requirements are of course only needed in case if you want to work with ext3 filesystems.

memtest86

Memtest86 is thorough, stand alone memory test for x86 architecture computers. BIOS based memory tests are only a quick check and often miss many of the failures that are detected by Memtest86.

chntpw

The offline NT password editor (chntpw) is a little program wich enables you to view and change passwords in a Windows NT SAM user database. For example,

Installation

# cd mkcdrec; tar zxvf mkCDrec_v0.7.9_utils.tar.gz
# ls -l utilities

This is a Linux Live CD based on KNOPPIX technology using mostly pure Debian/sid.
Most tools follow the GNU GENERAL PUBLIC LICENSE. If you are in doubt, look at the specific docs.
Main features:
- Kernel 2.6.11.11 with many patches
- ACPI and DMA enabled by default (can be disabled with acpi=off and nodma respectively)
- i586 optimization - not for use with older CPUs!
- 128 MB RAM required, 256 MB RAM recommended
- Unionfs support (with unionfs cheat)
- AVM Fritz!Card DSL support
- Eagle USB DSL support
- KDE 3.4.1
- Captive 1.1.5
- OpenOffice 1.9.104
- ALSA 1.0.8
- GRUB boot loader for CD start - ideal for rescue in command line mode
- Memtest86+ - Advanced Memory Diagnostic Tool in the extra menu of the boot loader
Simply boot from CD and enjoy Linux. Some tools may request a root password. As none is set, you have to set one using "sudo passwd" or use "su" in konsole.
Whenever you execute something with root permissions, you should know what you are doing! For web surfing over LAN no root access is required. I am sure you can discover many things to do with it :)
Dont try to write to NTFS partitions using the standard NTFS driver included with the kernel, as its support for writing is very lacking - thus it could destroy the partition and the data in it.
There is a new Captive NTFS driver that does a better job at writing to NTFS, so use it instead. For FAT partitions you can enable write-access with the context menu (right mouse button).
You may not have the rights to modify Linux partitions, use the root mode in konsole if needed. Some links are not working in the menu - that is not my fault - the packages from Debian/sid are very new and may have some little bugs, but you can always use new releases.

Recovery Is Possible (RIP) is a Slackware-based CD or floppy boot/rescue/backup/maintenance system. It has support for a lot of filesystem types (Reiserfs, Reiser4, ext2/3, iso9660, UDF, XFS, JFS, UFS, HPFS, HFS, MINIX, MS DOS, NTFS, and VFAT) and contains a bunch of utilities for system recovery.
R.I.P. also has IDE/SCSI/SATA, PCMCIA, RAID, LVM2, and Ethernet/DSL/cable/PPP/PPPOE network support.
The bootable CD image `RIP-12.4.iso.bin can be written to a CD/DVD disk, using cdrecord/dvdrecord etc.
The 2.6.11.6 kernel has IDE/SATA and SCSI support. The kernel also has PCMCIA, LVM2, RAID, and Ethernet/cable/dsl/ppp/ pppoe/wireless networking support.
These are some of the programs it contains (partimage/partimaged, parted, dump/restore, reiserfsck, fsck.reiser4, fdisk, cfdisk, sfdisk, mke2fs, e2fsck, tune2fs, debugfs, mkfs.xfs, jfs_mkfs, jfs_fsck, xfs_repair, cdrecord/dvdrecord, mkisofs, dvd+rw-format, growisofs, ntfsresize, mkntfs, lynx, mutt, fetchmail, pop3spam, popselect, ncftp, epic irc, tin, telnet, wget, naim, zgv, testdisk, smbclient, smbmount, ssh/sshd, rsync, udp-sender/receiver, lde, blesstivo, rtvpatch, chntpw, cmospwd, grub, grubconfig, smartctl, memtest86, captive-ntfs, ddrescue, dd_rescue, acpitool, dmidecode, hwinfo, lshw, ethtool)
It also includes the DVD udf filesystem packet writing tools (cdrwtool, mkudffs, pktsetup).
The reiserfsck and fsck.reiser4 programs are used to check and repair a Linux reiserfs and reiser4 filesystem.
The xfs_repair program is used to repair a Linux xfs filesystem.
The jfs_fsck program is used to check and repair a Linux jfs filesystem.
The e2fsck program is used to check and repair a Linux ext2 or ext3 filesystem.
The ntfsresize program non-destructively resizes Windows XP/2000/NT4 or Windows Server 2003 NTFS filesystems. Read /usr/doc/RIP/ntfsresize.txt on the rescue system.
The parted program is used for creating, destroying, resizing (fat16/32, ext2/3, reiserfs v3.6), checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data between hard disks and disk imaging.
The partition image program partimage saves partitions in the ext2, ext3, reiserfs, jfs, xfs, ufs, ntfs, fat16, and fat32 formats to an image file. Only used blocks are copied to save space and increase the speed. The image file can be compressed, in gzip or bzip2 formats.
Enhancements:
- A few fixes and updates were done.
