Read-only Root Filesystem
In my previous posts about ramdisks and persistent storage on my Raspberry Pi, I explained my goal to reduce write access to the sd card as far as possible. The last step is to mount the sd card read-only, so its filesystems can almost never get damaged. This is the …

Intel Centrino IPW2200 Monitor Mode unter Linux
Nach meinen bisherigen Versuchen unterstützt der im Linux Kernel enthaltene Treiber für den Intel IWP2200 Centrino WLAN-Chipsatz (zumindest bis Version 2.6.15.1) nicht den Monitor Mode. Man kann diesen Modus aber durch Selbstkompilieren der nötigen Treiber aktivieren und dann Tools wie Kistmet verwenden, um WLANs auf Schwachstellen hin …
