My daily WTF: The following script reproducibly makes my desktop Ubuntu stop. The script deploys files to a cluster of 20 machines. In order not to wait for 20 subsequent rsync executions, I sent each one to the background. Bad idea...
while read p; do
rsync from-path $p:to-path &
done < slaves
Ich hatte für den Faxversand und Push Service der FritzBox bisher das T-Online-E-Mailkonto eingetragen als Absender. Diese Einstellungen funktionierten allerdings plötzlich nicht mehr. In der FritzBox konnte man unter "System" > "Push Service" > (Haken bei "Test E-Mail") "Übernehmen" sehen, dass keine E-Mail versendet werden kann.
Es haben sich anscheinend zwei Dinge verändert: Man kann E-Mails nur noch verschlüsselt verschicken, wozu eine Änderung des SMTP-Servers und des Ports nötig ist. Zudem wird dann zwingend ein Passwort benötigt, welches nicht einem bereits existierenden Standard-T-Onlinepasswort entspricht (trotzdem man sich mit diesem wiederum im Webmailer einloggen kann... 
).
Kochrezept:
1. Separates neues E-Mailpasswort anlegen unter https://kundencenter.telekom.de/kundencenter/kundendaten/passwoerter/email-passwort-einrichten.html.
2. In der Fritzbox unter "System" > "Push Service" folgendes eintragen:
After migrating an extension of the dd_googlesitemap from T3 4.5 to 6.2, I noticed a very strange behavior which occurred after every cache clear in the install tool. Every call of index.php?eID=dd_googlesitemap or a custom sitemap index.php?eID=dd_googlesitemap&sitemap=customsitemap resulted in the following error:
#1: PHP Warning: Invalid argument supplied for foreach() in [...]/typo3_src-6.2.3/typo3/sysext/core/Classes/Utility/RootlineUtility.php line 269
The error is misleading, because it seems to have nothing to do with the skipRootlineCheck option the extension provides. The error simply disappears when accessing the frontpage after the cache clear, just before accessing the sitemap.
I was about to check out a remote repository when I got the following error:
git clone https://xyz git-repo/
Cloning into 'git-repo'...

In this case, it was due to a missing master branch. I needed to add a branch name to the checkout command with -b and the checkout worked as expected.
In our standard webserver configuration, we use Apache + PHP-FPM on Ubuntu. Apache runs with a different user and a different group than PHP. This implies that all files that are to be readable by Apache need to be world-readable. PHP creates files that are not world-readable by default.
I intended to set the creation mask within php.ini or better on a per-pool basis. Sadly, both seems not to be possible.
I finally managed to change this behavior by changing umask in the start script /etc/init.d/php5-fpm from 0007 to 0000.
