Free linux ext2 ext3 data recovery by unistal 10.12 software for linux

The gzip Recovery Toolkit attempts to automate the recovery of data from corrupted gzip files (including tarballs) through a program called gzrecover. gzip Recovery Toolkit package is still very experimental at this point.
99% of "corrupted" gzip archives are caused by transferring the file via FTP in ASCII mode instead of binary mode. Please re-transfer the file in the correct mode first before attempting to recover from a file you believe is corrupted.
This program is provided AS IS with absolutely NO WARRANTY. It is not guaranteed to recover anything from your file, nor is what it does recover guaranteed to be good data. The bigger your file, the more likely that something will be extracted from it. Also keep in mind that this program gets faked out and is likely to "recover" some bad data. Everything should be manually verified.
Usage:
Run gzrecover on a corrupted .gz file. Anything that can be read from the file will be written to a file with the same name, but with a .recovered appended (any .gz is stripped). You can override this with the -o option.
To get a verbose readout of exactly where gzrecover is finding bad bytes, use the -v option to enable verbose mode. This will probably overflow your screen with text so best to redirect output to a file.
Once gzrecover has finished, you will need to manually verify any data recovered as it is quite likely that our output file is corrupt and has some garbage data in it. If your archive is a tarball, read on.
For tarballs, the tar program will choke because GNU tar cannot handle errors in the file format. Fortunately, GNU cpio (tested at version 2.5 or higher) handles corrupted files out of the box.
Heres an example:
$ ls *.gz
my-corrupted-backup.tar.gz
$ gzrecover my-corrupted-backup.tar.gz
$ ls *.recovered
my-corrupted-backup.tar.recovered
$ cpio -F my-corrupted-backup.tar.recovered -i -v
If you have a previous release, please note that the patches to GNU tar have been discontinued. They were only marginally successful at best and GNU cpio does what is needed out of the box and does it far better.
Enhancements:
- Documentation updates, including a man page, plus code cleanup to better enable inclusion in GNU/Linux packages and eliminate compilation warnings.

Linux Commander is a powerful file manager for the X Window System.

It is partially modelled after Window Commander for Windows.

Linux Mobile System project (LMS) is a full Linux system whose support is the new USB Flash Memory Drives. The intention is to boot any PC with USB support with our system and therefore we will have every administration and analysis applications that we have selected, so we will not need install it. This way, always we will be able to get our Linux system ready to use in our pocket.
This project arose with the intention to study the Linux system of exhaustive way and simultaneously enjoy with it. The initial idea is to fuse two separated disciplines: the programming and the systems management. So well center our study in the denominated "system programming, as much networking level as at device level (drivers).
Main features:
- To initiate our Linux system from memories flash USB.
- The system will be a selection of common GNU tools in every system: disk diagnosis, memory, hardware, networks monitoring tools, etc.
- LMS Tux
- As far as possible well develop new tools and/or utilities with the objective to study deeply the underlying technology.
- The programming languages used will be C, C++, Python and Perl, without forget the system shell scripts.
- The resources minimization (disk space, memory...) isnt a functional objective of the developments.
LMSs main aim is to achieve a highly specialized distribution of GNU/Linux which can carried through the USB Flash Memory Drives. Once the distribution is ready in the USB device, it can be carried in your own pocket and you can start up any PC x86 with no need to install it directly in the PC.
The LMS system is aimed at the development of specific tasks such as network administration, security analysis of networks, and recovery and repair of host data, as well as all information exchange, which is what makes it different from other portable systems such as "live CDs". The main idea is to carry all the potency of Linux and our tools in our own pockets, ready to be used.

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.

Tao Linux (pronounced dow Linux) is a project to build a free Linux distribution from the sources used in the Red Hat Enterprise Linux product line.
The target market is either experienced system administrators who would like freely available binaries of this code, or end users who are interested in experimenting with enterprise functionality.
Besides being mostly compatible with Red Hat Enterprise Linux 3, it also includes software packages such as Eclipse and clustering tools not found in the base RHEL products.
Main features:
- Includes gcj-compiled Eclipse IDE
- Includes clustering tools
- Yum with protectbase patch for safer use of 3rd-party repos
- Supports ACLs in ext3, nfs and Samba
- Many packages for Red Hat Enterprise Linux also run on Tao Linux
- Free as in speech and beer
- Security updates (in SRPM form, at least) available into 2008

Ext2 compression extension (E2compr) is a small patch against the ext2 filesystem that allows on-the-fly compression and decompression. It compresses only regular files; the administrative data (superblock, inodes, directory files etc.) are not compressed (mainly for safety reasons).
Access to compressed blocks is provided for read and write operations. The compression algorithm and cluster size (see section Clusters) is specified on a per-file basis. Directories can also be marked for compression, in which case every newly created file in the directory will be automatically compressed with the same cluster size and the same algorithm that was specified for the directory.
E2compr is not a new filesystem. It is only a patch to the ext2 filesystem made to support the EXT2_COMPR_FL flag. It does not require you to make a new partition, and will continue to read or write existing ext2 filesystems. You should consider it is only a way for the read and write routines to access files that could have been created by a simple utility similar to gzip or compress. Compressed and uncompressed files will coexist nicely on your ext2 partitions.
Usage
Basically, a file is compressed with the command `chattr +c filename, and decompressed with the command `chattr -c filename. You can also do `chattr +c (etc.) on a directory. The directory itself wont be compressed, but any new files created in that directory inherit that directorys compress flag and compression algorithm and cluster size.(1)
Use lsattr to see if a file should be compressed or not, and to see what compression algorithm and cluster size will be used.
Use e2ratio to see how much disk space is used by the compressed form compared to the uncompressed form.
You can also try the `-u or `-r options to lsattr. (The difference is that, for directories, e2ratio finds the disk usage of the whole directory tree, like du, whereas `lsattr -u only shows the space taken by the directory file, like `ls -s.)
Enhancements:
- kernel 2.4.26 and 2.6.18.5 patch sets.
- Allows repeated compress/decompress cycles.
- The ability to compile within a compressed directory tree.
- This release corrects small file sizes and fixes all known GPFs.
- It removes compiler warning messages and regularizes debug output.
