Guarddog

Security

Nothing's more irritating than failing hardware : what's the use of having a RAID 0+1 setup in your dedicated firewall box at home, when the disks refuse to boot from. I could mount them with a Knoppix live CD, but restoring the bootsector gave me the weirdest errors in Grub and Lilo. As I didn't had that much time handy, I finally decided to install Guarddog, a personal firewall, on my desktop and to initiate the ADSL call from that machine.

Time to start looking for a integrated router/firewall/access point.

Grsecurity for 2.6.7

Security

Cool ! Grsecurity is finally available for Linux 2.6.7, and grsecurity.net has a brand new spiffy design.

Enigma

Security

While struggling my way through documentation of 3DES encryption, I found a site explaining in detail about the Enigma, a typewriter like machine, used by the Nazi''s in World War II to encrypt military messages. This article is a lengthy piece which appeared originaly in Nautical Brass magazine, and reads like a book :

The Enigma could have been unbreakable, at least with the methods available at the time, had the machine been used properly. The biggest mistake the Germans made was their blind belief in the invincibility of Enigma. Procedural errors in using the machine, combined with occasional operator laziness, allowed the Poles and, subsequently the British, to crack the "unbreakable" codes.
