Freitag, Januar 21st, 2011

Downloading and extracting large tarballs usually takes plenty of time. Extracting tarballs during the their transfer reduces the waiting time because you a) don’t need to do wait for the transfer to finishes before starting the extraction and b) the machine doesn’t have to read the tarball from the disk while simultaneously writing to it.

Converting MBR Partition Tables to GPT

Donnerstag, September 23rd, 2010

MSDOS MBR Partition Tables make it impossible to use Partitions larger than 2 TiB. This is a pitfall you maybe will be faced with after expension of a RAID array. The only solution is to convert the MBR Partition Table to GPT (GUID Partition Table).

Solr Multicore: Installation, Configuration

Donnerstag, September 9th, 2010

Luckily Solr already [...]

Debian Lenny: pam_mount, files and loop devices

Donnerstag, Juni 17th, 2010

When I was trying to automatically mount an encrypted image at login using pam_mount, I encountered a strange problem:
I wasn’t able to find any errors in my configuration (at least none connected to this behaviour), but mount.crypt was unable to mount the image.
Enabling debugging in pam_mount.conf.xml (<debug enable="1" />) revealed the command used for mounting:
pam_mount(misc.c:272) [...]

suPHP und PHP Opcode Caches

Samstag, August 29th, 2009

Eigentlich ist suPHP eine nette Sache. Das Apache Modul mod_suphp sorgt in Kombination mit einem SetUID Binary dafür, dass PHP-Skripte mit den Berechtigungen des Benutzers, dem sie gehören, ausgeführt werden. Damit das funktioniert muss man in Binär-Distributionen wie etwa Debian Linux nicht mehr tun, als dass Modul zu installieren, einen Blick auf dessen Konfiguration zu [...]
