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.

FTP downloads of CRK for Linux

if passive ftp doesn't seem to work, try switch passive off. Recently the Big Browsers like google chrome and now also opera have switched ftp off by default, labeling it a "dangerous" experiment. If you know the dangers you can still use ftp:// from your browers . Here's how to enable old-style ftp inside opera. As of opera-stable_78.0.4093.147 the Big Browsers came to the conclusion that the ftp:// experiment had become to dangerous. If you know the dangers you can still obtain the older versions and are available here.

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 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.

Webster's Hypertext Gateway for dictd on ubuntu 20.04

  • Webster's Hypertext Gateway interface, dict-webinterface, provides a point-and-click client interface (for non-linemode browsers) for accessing various dictionary services on the Internet. It uses apache2, mod_cgi and interfaces with dictd which is open at port 2628. dict-webinterface is very tiny and therefor the fastest gear available for this task.

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
