Crash Recovery Kit for Linux
Crash Recovery for Linux sounds a bit superfluous. Linux is regarded
as one of todays most stable Operating Systems. In the case of some
hardware failure like a broken disk it can however be handy.
Of course your machine doesn't have to have linux installed to make use
of the CRK kit. There are several uses and purposes for the CRK to
be used. To name a few :
- recovery of a trashed LILO boot record. How many times does it
happen that some person installs windows 98/95 after he/she installed
linux? Well in that case windows 9X just overwrites the MBR record
and linux won't be able to boot anymore.
- backup over the network in the form of tar.gz tarballs. Both
FAT16, FAT32, ext2 and all filesystems which Linux supports in a
read/write fashion can be taken care of. The strong part of the CRK
is when a disk is replaced or repartitioning is being done. The
CRK boots a complete mini linux with networking where all possible
hardware which is inside the Linux kernel is available.
- Testing hardware of new intel based machines.
- Detecting versions and types of hardware. The Linux kernel holds
a large database of hardware supported. Booting a linux kernel doesn't
only resolve if the hardware is ok, it also show its specs. This
can be handy if one wants to check-out an old/new PC which is for sale.
- Recovery of a misconfigured or hacked Linux system. Well that can happen.
/etc/fstab can be wrong or the root password is unknown etc.
- make a tape backup of a disk which can't be booted anymore.
The CRK is based on RedHat Linux. I have always used RedHat systems, thats
why. When my system needed maintenance the rescue floppy image which RedHat
supplies didn't fullfill my needs. Thats why i created the CRK. Lately
i use Mandrake. How and why the CRK was created read the short history.
The CRK is licensed under the GNU Public License (GPL).
See the Changelog for whats included.
if passive ftp doesn't seem to work, try switch passive off
Mirror's
The gzip Recovery Toolkit
Custom PXE boot support
MP3 Rip Kit for Linux
- A hyperthreading commandline tool for encoding
your audio cd albums with lame as
fast as your Linux iron allows it.
OSS DVD Extensions for cdrtools-2.0
- A Open Source patch which add DVD extensions
to cdrtools-2.0. As a convenience also SRPM and RPM packages for several
RPM based Linux distro's are given.
Perl-less Sender Policy Framework SPF on Qmail 1.03
- Although Perl is a nice tool inside UNIX/Linux, why should
it be fired up 10.000 times a day as part of a UNIX/Linux
email server system? The peoples from Amavis, Spamassasin,
and also OpenSPF.org however seem to ignore this, as they
only implement and test their reference sofware as a Perl
package. Why, why should one add a Perl plugin into Qmail ??
After short thoughts i rejected this approach, and created my own
gear for running SPF1, SRS1, SRS2 on Qmail 1.03.
ClamAV 0.90.2 with old perl-les amavis
- If you are running some old mailserver (RedHat 6.2 or 7.3 on a
P3 500MHz), you might wanna look at the old fast version of
amavis which runs without perl.
The old version which i maintain, currently amavis-0.2.4, now also
automaticly selects and configures to use ClamAV 0.90.2 if installed.
Mozilla Firefox 1.5.0.7 on Mandrake 10.1 i586/x86_64
- The open source browser Mozilla Firefox Version 1.5.0.7
is backported from Mandriva 2006.0 to Mandrake 10.1 i586/x86_64.The
result is surprising and stunning as even flash9 now works like it should.
RSA speed benchtest
- Test your computer's crypto speed. The CRK 2.4.18 based
RSA speed benchtest measures
your PC's encrypting power. basicly proceed as with any CRK, i.e.
login as root, install-cdrom, install-utils and next do install-openssl.
The RSA benchtest should be run at least twice. To run the test run:
# openssl speed rsa
