Da auf meinem Rootserver zum wiederholten Mal Probleme mit der zweiten Festplatte (/dev/sdb) auftraten, wurde diese soeben im Rechenzentrum getauscht (ein Lob an Hetzner für den schnellen Support). Da die Platte Bestandteil eines Software RAID1-Verbunds ist, kurz die Schritte zum Entfernen und anschließenden Reaktivieren der Platte.
Zuerst alle Partitionen der Platte auf faulty setzen und anschließend aus dem jeweiligen Array entfernen:
On a server, I use logcheck to get an email based on logfile analysis if anything goes wrong and doesn’t fit the usual patterns. In addition, I use sSMTP to forward all sent mails to my mailserver. Unfortunately, this solution ends up in sending a mail like the following every hour because of a bug in logcheck’s ignorefile for sSMTP.
Dec 12 22:02:06 hostname sSMTP[22391]: Sent mail for logcheck@hostname (221 2.0.0 Bye) uid=101 username=logcheck outbytes=639
To fix this, I replaced the contents of the file /etc/logcheck/ignore.d.server/ssmtp with the following lines:
^w{3} [0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2} [a-zA-Z0-9]+ sSMTP[[0-9]+]: Sent mail for logcheck@.*$
^w{3} [0-9] [0-9]{2}:[0-9]{2}:[0-9]{2} [a-zA-Z0-9]+ sSMTP[[0-9]+]: Sent mail for logcheck@.*$
I removed the other lines, because sSMTP shouldn’t do anything else on the system and if it would, I’d like to be informed. If you need more ignore patterns you might have to keep/edit some of the original lines.
In Magento it is possible to access a product’s attributes with a simple getter method. Let’s get the attribute test:
$_product->getTest()
This works as long as test is an attribute of type ‘text’. If the attribute is a dropdown, the method will just return the id of the selected option. To get the dropdown text, you need to call another method:
Lately, I wanted set up a Ubuntu Hardy DomU on an existing Debian Etch Dom0 box. Usually, setting up Debian-based DomUs is very simple with xen-create-image and debootstrap (there are tons of tutorials out there dealing with this topic), but unfortunately Etch’s version of debootstrap doesn’t support Ubuntu Hardy. I spent a surprisingly long time on searching the net until I found a solution for this problem on a french site: Installer et configurer Xen sur Debian 4.0 Etch (it’s a complete howto for Xen on Debian Etch, but it deals with the Hardy part too). The author created a backport of the debootstrap package, which enables you to debootstrap Hardy.
First, you have to create the hardy.d directory (symlink) for xen-tools.
$ cd /usr/lib/xen-tools
$ ln -s ubuntu.d hardy.d
There’s a debian repository holding the backport package, however I got problems to use that repository on an amd64 box, so I downloaded and installed the package manually.
“Cygwin is a Linux-like environment for Windows.” This means, you can use linux/unix commandline tools like ls, grep and find on your Windows system. However, the default installation of Cygwin uses Windows’ default commandline terminal cmd.exe, which is not really handy. Fortunately, there’s a solution to use PuTTY as Cygwin terminal.
Download and install Cygwin. The setup will download all needed packages, so make sure you check what you need (my main reason to install Cygwin was to have a Git client on Windows)
Download PuTTYcyg and extract the contents of the archive anywhere on you hard drive
Start putty.exe, select Cygterm as connection type and enter - (dash) as command. Enter a session name (e.g. cygwin) in the text field below Saved Sessions and click on Save.
Create a shortcut to putty.exe. Right click the shortcut, select Properties and append the following string to the target field: -load "cygwin". Of course you have to replace cygwin with the name of the session you saved in PuTTYcyg.
Open the shortcut and you should directly get into your Cygwin shell
As the documentation on Magento is a bit…spread around the web: here’s a collection of links to guides and hints how to deal with magento’s templating system (partially german). I will add more as I find them.
When configuring VPN connections in Ubuntu through network-manager-pptp the connections don’t get displayed until a reboot due to a bug. In the bugtracker I found a solution which makes the connections available without a reboot.
First, restart dbus
sudo /etc/init.d/dbus restart
Then run the NetworkManager applet by opening a command window with ALT+F2 and typing in nm-applet.
CONGRATULATIONS!!!!
WHY ?? BECAUSE YOU ARE ONE OF THE VERY VERY VERY FEW WHO READ THE README FILE!!
But because the other, huge percentage do NOT, we moved the actual contents
of this file into IGNOREME file because the chances for most of the people to
read IGNOREME are at least the chances to read README (more than that, we
believe they are really much higher).
So now, go read IGNOREME with the actual contents what you would have
expected here.
