Aladdin Knowledge Systems und die Sicherheits-Experten der LSE stellen auf der Systems zusammen zwei neue Angebote für das sichere Arbeiten mit Unternehmensdaten vor.
Der Einsatz von Windows-Zertifikaten und Smart Cards unter Linux wird am Messestand demonstriert. Die Lösung sei einsetzbar mit der PKI-Software aller relevanten Hersteller. Das neue Angebot sei für jene Unternehmen interessant, die mit gemischten Systemwelten (Windows, Unix, Linux) arbeiten oder dies planen, so Aladdin. Dabei soll der plattformunabhängige Einsatz von Zertifikaten alle Ebenen eines Unternehmens unterstützen. Das reiche bis zu den Windows-Zertifikaten in Mozilla Firefox.
This is going to be primarily a geeky post, so I'll keep the non-geeky stuff to the top so you don't have to read it if you don't want to. In non-geeky news, the recent Clutch album is hella good. Well, it's not exactly new, but it's still damn good. "The Incomparable Mr. Flannery" might be my favorite song. The line "Stole my Camaro, primer gray" kills me every time. Damn, I miss my butt-rock Camaro sometimes.

Just upgraded to dovecot 1.0alpha3 on the mail machine (which is an OpenBSD box). It seems weird that the author considers it *the* version to use, yet won't remove the alpha tag. You'd think it'd be a beta. Anyway, had a few growing pains in the config file (the new one doesn't care for some of the old config options) so I had to take the example config for the new dovecot and bring it up to speed. The biggest thing I found once it was up and running was with mailbox locking....I had to add the group that owned /var/mail to the mail_extra_groups line.
Well ... yet another blog entry !
Finally I got my gentoo back online. Now I can expect a couple of days of compiling and - hopefully - I can start using the system then.
It has been somewhat broken since I had to take it down 6 months ago when I had to move.
Now Im online through a kind neighbours accesspoint and a borrowed cnet 611usb.
Took a bit of work since I had no wifi tools at all installed and the driver from atmel on the cd didnt work. After countless reboots to windows to download individual packages and drivers it finally succeded.
I'm installing Ubuntu on the Powerbook to see if it solves my sleep woes. I've narrowed down what's up (I think). The system will sleep and wake up once, and it will go to sleep a second time, but it will never wake up. The Flashing LED stops, but the screen never turns on, hard disk doesn't start running (that I can tell), etc. Ubuntu looks like it's got a decent amount of active development.
Linux System Admin Tips There are over 200 Linux tips and tricks in this article. That is over 150 pages covering topics from setting and keeping the correct time on your computer, permanently deleting documents with shred, making files "immutable" so that root cannot change or delete, setting up more than one IP address on a single NIC, monitering users and processes, setting log rotate to monthly with 12 months of backups in compressed format, creating passwords for Apache using the htpasswd command, common Perl commands, using cfengine, adding users to groups, finding out which commands are aliased, query program text segment size and data segment size, trusted X11 forwarding, getting information on the hard drive including the current temperature, using Gnuplot, POVRAY and making animated GIFs, monitoring selective traffic with tcpdump and netstat, multiple examples using the find command, getting the most from Bash, plus a lot more.
Title : Linux 2.6 Stack Protection
O/S : Linux
Distro : ALL (Tested on Slackware and Kubuntu)
I have compiled a 2.6.10 with KGDB patches on FC3.
My Connections are made correctly .
But after connections i get error message .
Following is the complete output of my console after
runnig GDB on my development machine ,which i saw on
[root@58-125-109-203 linux-2.6.10]# gdb vmlinux
GNU gdb Red Hat Linux (6.1post-1.20040607.41rh)
Now that I've done this....twice, I figure I might as well put this info on my blog so I (or maybe someone) else can retrieve it in case of problems in the future.
After screwing around with various OS's, I decided to settle on Yellowdog 4 for my PowerBook. Unfortunately, Yellowdog isn't what it used to be. YDL 3 installed very well and had few problems. YDL 4, on the other hand, does have a few problems when installed on this machine.
I don't know what it is, but I seem to be running into a lot of people lately who are against static typing. And most of theses people who dismiss static typing have a seemingly narrow view of what it enables. I assume this comes from lack of experience with good statically typed languages (here I'm thinking a language like Haskell or and ML dialect with a "modern" type system. Something with polymorphic types and type inference, like the Hindley-Milner system (circa 1970's)). What I'd like to do is present another view that many people are apparently unaware of.
I'm totally confused by recent experiences.
let me back up a few steps, and give some history first:
My brother, a non-linux non-geek hard core gamer wanted me to set him up a small server for a couple things he and his 'clan' could use. Teamspeak and Neverwinter Nights stand alone server were two of the things he wanted.
I have been working on desktop rotation in linux for some time. Achieved something good till now. ya! i found something written by Hamish Rodha for KDE, but the frustating part has been that it works only on KDE and liited to Nvidia cards. I wanted to make it more generic. So tried to hook the KDE/GNOME calls in XLIB. Till now things has been moving fine but not stuck to a block. For the last few days working on rotation of window. but yet to find the Xlib function where i can hook.
Can some GCC expert help me figure out the right combination of settings for optimizing software w.r.t speed ?
I have tried "-O3 -mtune=pentium4 -msse2" . Can I do better by adding "-floop-optimize2" or "-ftree-vectorize" or "-funroll-all-loops" ? Are there any other compiler otions that I should be considering ? I am specifically working on optimizing a video decoder software for purposes of integrating it into a player and I am working on a Linux PC that uses kernel ver 2.6.9. Thanks for any suggestions
