I just finished playing with some nCipher’s HSM. Unfortunately there is no integration guide for OpenSSL that cover CHIL interface and nCipher hardware security modules.

nCipher’s installation guide is quite good, but after you finish installing hardware, drivers and daemons, you are on your own.

I found only two helpful sources: Andrea Campi’s blog entry about nCipher [...]

AskApache Google 404 default 404.php does not work properly with Atahualpa theme. To fix those problems create another 404.php file in /themes/atahualpa with this content:

<?php ob_start(); include(TEMPLATEPATH . '/functions/bfa_get_options.php'); get_header(); if (function_exists('aa_google_404'))     aa_google_404(); else { ?>     <h2><?php _e('Not Found','atahualpa'); ?></h2>     <p><?php _e("Sorry, but you are looking for something that isn't here.","atahualpa"); ?></p> <?php } bfa_center_content($bfa_ata['center_content_bottom']); get_footer(); exit(); ?>

Routing messages from one input queue to two output queues in ActiveMQ can be done in two different ways. Apache Camel, a powerful rule-based routing engine often used with ActiveMQ, is a typical choice. Virtual composite queue is another solution. Which to choose? The faster.

Apache Camel

Camel configuration I use:

<beans    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">     [...]

W styczniu opisałem jak zainstalować dopasowaną do własnych potrzeb dystrybucję OpenWRT na routerze ASUS WL-500g Premium. Pora na aktualizację.

Kopia zapasowa

Na wszelki wypadek, gdyby aktualizacja się nie powiodła warto wykonać kopię bezpieczeństwa aktualnego systemu. Informacje na temat wykonywania kopii całego oprogramowania (kernel + squashfs + jffs2) znajdziemy w wiki pod hasłem “BackupAndRestore“.

Aktualizacja źródeł

Zgodnie z instrukcją na [...]

Migrating from ActiveMQ-CPP/CMS version 2.2.6 to 3.0.1 is very easy. There are only two minor problems to deal with.

First problem: exceptions

No idea what “N3cms12CMSExceptionE” is? Use getCause() on cms::CMSException objects to get std::exception*. Do not call what() directly. Do not try to call what() from any base classes.

catch (cms::CMSException& e) {     cout << e.getCause()->what() << [...]

Szwajcarskie noże oficerskie słyną ze swej funkcjonalności. Odkąd zaczęto produkować wersje z wbudowaną pamięcią flash na USB zastanawiałem się, jak zapewnić oprogramowaniu zainstalowanemu na przenośnej pamięci równie dużą funkcjonalność.

PenDrive do zadań specjalnych

Plan minimum to możliwość uruchamiania z pamięci klucza USB przynajmniej:

Programu rozruchowego GRUB Ultimate Boot CD Parted Magic OS

Dodatkowo przydatna byłaby dystrybucja typu LiveCD (Debian Live?) oraz [...]

GNOME can be easily optimized for Netbooks using configuration editor. Disabling animations, thumbnails and splash screen speeds up GNOME while scaling down icons saves space on desktop.

Metacity will give the user less feedback by using wireframes, avoiding animations, or other means if /apps/metacity/general/reduced_resources is set to true. This can be set with gconf-editor or from [...]

X.Org form ports works fine with cirrus driver, but starts in 800×600 only. Small tweak to configuration file is needed to run X in higher resolutions.

Install X.Org and drivers

First install xorg, xf86-video-cirrus and xf86-input-keyboard ports.

DBus and HAL

Installing DBus and HAL allow X Server to guess hardware configuration and work without any configuration file.

If your console [...]

First generate Doxyfile skeleton like usual:

$ doxygen -g Doxyfile.in

Then open Doxyfile.in in $EDITOR and set following variables:

Debian GNU/Linux provides several packages that can be used to audit C/C++ source code. First three search for programming errors that might lead to potential security flaws: flawfinder rats pscan Next two tools find bugs in C and C++ source code by doing a static check too, but their checks are not security-related: splint cppcheck

To make whole home network use OpenDNS I need to change only 3 files on my OpenWRT router. First step – resolv.conf Create /etc/resolv.conf.opendns with OpenDNS servers addresses, eg: nameserver 208.67.222.222 nameserver 208.67.220.220 Make sure /etc/resolv.conf defines 127.0.0.1 as a name server. Second step – dnsmasq In /etc/config/dhcp set resolvfile variable: option resolvfile '/etc/resolv.conf.opendns' Restart dnsmasq with: # /etc/init.d/dnsmasq restart Third step – /etc/hotplug.d/iface This step is [...]

Ostatnio wydziałem tę procedurę w Gnome. Cała praca użytkownika to kilka kliknięć myszą. A na konsoli wystarczy tylko: pmount sda1 && cp /media/sda1/*.jpg ~/NEW && pumount sda1 Za pomocą exiftran i prename możemy zdjęcia obrócić do właściwej orientacji i zmienić ich nazwy. Zamiast obracać każde zdjęcie ręcznie można użyć: exiftran -ai *.jpg … i obrócić wszystkie do ich właściwej orientacji [...]
